privacy practices. Following randomization, patients began the double-blind phase of treatment. Topamax can increase the level of acid in your blood (metabolic acidosis). The dosage should then be increased at 1- or 2-week intervals by increments of 1 to 3 mg/kg/day (administered in two divided doses), to achieve optimal clinical response. In this open-label, uncontrolled study, the mortality was 37 deaths/1000 patient years. TOPAMAX can be taken before, during, or after a meal. It blocks a specific type of receptor found in the prostate. Tell your doctor about all your other medicines, especially: other glaucoma medications, including eye drops. Brand names: Topamax, Topamax Sprinkle This finding was not statistically significant. In the monotherapy epilepsy controlled trial, the proportion of patients who experienced one or more cognitive-related adverse reactions was 19% for TOPAMAX 50 mg/day and 26% for 400 mg/day. Call your doctor for medical advice about side effects. The risk for cognitive adverse reaction was greater in younger patients (6 to 11 years of age) than in older patients (12 to 17 years of age) [see WARNINGS AND PRECAUTIONS]. We comply with the HONcode standard for trustworthy health information. Remember, keep this and all other medicines out of the reach of children, never share your medicines with others, and use tamsulosin only for the indication prescribed. The median average daily dosages were 47 mg/day, 86 mg/day, and 150 mg/day in the target dose groups of TOPAMAX 50, 100, and 200 mg/day, respectively. If left untreated, metabolic acidosis can cause brittle or soft bones (osteoporosis, osteomalacia, osteopenia), kidney stones, can slow the rate of growth in children, and may possibly harm your baby if you are pregnant. acting aggressive, being angry, or violent, an extreme increase in activity and talking (, other unusual changes in behavior or mood. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use. The mean migraine headache frequency rate at baseline was approximately 5.5 migraine headaches/28 days and was similar across treatment groups. The purpose of this registry is to collect information about the safety of TOPAMAX and other antiepileptic drugs during pregnancy. Approximately 21% of the 159 adult patients in the 400 mg/day group who received TOPAMAX as monotherapy in Study 1 discontinued therapy due to adverse reactions. Hemodialysis is an effective means of removing topiramate from the body. The mean reduction from baseline to the last 12 weeks of the double-blind phase in average monthly attack rate, a key secondary efficacy endpoint in Study 13 (and the primary efficacy endpoint in Studies 11 and 12, of adults) was 3.0 for 100 mg TOPAMAX dose and 1.7 for placebo. The inactive ingredients are black pharmaceutical ink, cellulose acetate, gelatin, povidone, sodium lauryl sulfate, sorbitan monolaurate, sugar spheres (sucrose and starch) and titanium dioxide. If you have epilepsy and you stop taking Topamax suddenly, you may have seizures that do not stop. The relative risk for suicidal thoughts or behavior was higher in clinical trials for epilepsy than in clinical trials for psychiatric or other conditions, but the absolute risk differences were similar for the epilepsy and psychiatric indications. This registry is collecting information about the safety of antiepileptic drugs during pregnancy. Forty-nine percent of patients had no prior AED treatment and 17% had a diagnosis of epilepsy for greater than 24 months. In patients who develop unexplained lethargy, vomiting or changes in mental status associated with any topiramate treatment, hyperammonemic encephalopathy should be considered and an ammonia level should be measured. Patients who experienced a pre-specified minimum number of partial-onset seizures, with or without secondary generalization, during the baseline phase (12 seizures for 12-week baseline, 8 for 8-week baseline or 3 for 4-week baseline) were randomly assigned to placebo or a specified dose of TOPAMAX tablets in addition to their other AEDs. Selective alfa1-adrenergic antagonists are now first-line drugs in the medical management of BPH. The incidence of these abnormal shifts was 6 % for placebo, 10% for 5 mg/kg/day, 9% for 15 mg/kg/day, 14% for 25 mg/kg/day, and 11% for any topiramate dose. The bioavailability of topiramate is not affected by food. Follow your doctor's instructions about tapering your dose. information highlighted below and resubmit the form. Insomnia. Serious skin reactions (Stevens-Johnson Syndrome [SJS] and Toxic Epidermal Necrolysis [TEN]) have been reported in patients receiving topiramate. Some of the cases were reported after exposure to elevated environmental temperatures. It may not be safe to breastfeed a baby while you are using this medicine. However, tamsulosin will not shrink the prostate. Using a high-efficiency, counterflow, single pass-dialysate hemodialysis procedure, topiramate dialysis clearance was 120 mL/min with blood flow through the dialyzer at 400 mL/min. The numbers of patients randomized to each dose and the actual mean and median doses in the stabilization period are shown in Table 11. However, because of the absence of an appropriate control group, it is not known if this decrement in function was treatment-related or reflects the patients underlying disease (e.g., patients who received higher doses may have more severe underlying disease) [see WARNINGS AND PRECAUTIONS]. For its part, Boehringer Ingelheim offers the brand name Flomax at an online price of $35 for 30 capsules or $90 for 90 capsules with free home delivery. Benign enlargement of the prostate is a problem that can occur in men as they get older. dutasteride 0.5 mg-tamsulosin ER 0.4 mg capsule ext.release 24hr mphas Color: white,blue Shape: oblong Imprint: C280 0.5/0.4 This medicine is a orange brown, oblong, capsule imprinted with "GS 7CZ". Comparison of the Kaplan-Meier survival curves of time to first seizure favored the TOPAMAX 400 mg/day group over the TOPAMAX 50 mg/day group (Figure 1). Potential interactions between topiramate and standard AEDs were assessed in controlled clinical pharmacokinetic studies in patients with epilepsy. In rats, given probenecid to inhibit tubular reabsorption, along with topiramate, a significant increase in renal clearance of topiramate was observed. Some drugs can affect your blood levels of other drugs you use, which may increase side effects or make the medicines less effective. Its saturated solution has a pH of 6.3. Your reactions could be impaired. Your child's dose needs may change if the child gains or loses weight. Because clinical trials are conducted under widely varying conditions, the incidence of adverse reactions observed in the clinical trials of a drug cannot be directly compared to the incidence of adverse reactions in the clinical trials of another drug, and may not reflect the incidence of adverse reactions observed in practice. Efficacy of topiramate for the preventive treatment of migraine in pediatric patients 12 to 17 years of age is demonstrated for a 100 mg daily dose in Study 13 [see Clinical Studies]. The pharmacokinetics of topiramate are linear with dose proportional increases in plasma concentration over the dose range studied (200 to 800 mg/day). Somnolence and fatigue were the adverse reactions most frequently reported during clinical trials of TOPAMAX for adjunctive epilepsy. TOPAMAX is indicated as adjunctive therapy for the treatment of partial-onset seizures, primary generalized tonic-clonic seizures, and seizures associated with Lennox-Gastaut syndrome in patients 2 years of age and older. In multiple animal species, topiramate produced developmental toxicity, including increased incidences of fetal malformations, in the absence of maternal toxicity at clinically relevant doses [see Animal Data]. Patients taking estrogen-containing contraceptives should be asked to report any change in their bleeding patterns. seizures. TOPAMAX can slow your thinking and motor skills, and may affect vision. A 15% decrease in the AUC,ss of pioglitazone with no alteration in Cmax,ss was observed. The most common adverse reactions that occurred in TOPAMAX-treated pediatric patients 6 to 11 years of age, and at least twice as frequently than placebo, were gastroenteritis (12% topiramate, 6% placebo), sinusitis (10% topiramate, 3% placebo), weight loss (8% topiramate, 3% placebo) and paresthesia (7% topiramate, 0% placebo). The following adverse reactions were observed in at least 3% of patients on topiramate and were 3% to 7% more frequent than in patients on placebo: viral infection, bronchitis, pharyngitis, rhinitis, otitis media, upper respiratory infection, cough, and bronchospasm. Topamax may cause blurred vision and may impair your thinking or reactions. The most common adverse reactions in the controlled clinical trial that occurred in adult patients in the 200-400 mg/day TOPAMAX group with an incidence higher ( 10 %) than in the placebo group were: dizziness, speech disorders/related speech problems, somnolence, nervousness, psychomotor slowing, and vision abnormal (Table 6). The brand-name medication that tamsulosin oral capsules are based on is called Flomax. Systemic exposure (AUC) of the active metabolites, 4-trans-hydroxy-glyburide (M1) and 3-cis-hydroxyglyburide (M2), was also reduced by 13% and 15%, and Cmax was reduced by 18% and 25%, respectively. Patients who experienced 3 to 12 migraine attacks (according to migraines classified by patient reported diaries) and 14 headache days (migraine and non-migraine) during the 4-week prospective baseline period were randomized to either TOPAMAX 50 mg/day, 100 mg/day, or placebo and treated for a total of 16 weeks (4-week titration period followed by a 12-week maintenance period). Avoid becoming overheated or dehydrated in hot weather. In controlled clinical trials in adults, 11% of patients receiving TOPAMAX 200 to 400 mg/day as adjunctive therapy discontinued due to adverse reactions. The registry is collecting information about the safety of antiepileptic drugs during pregnancy [see Use In Specific Populations]. Tell your eye surgeon ahead of time that you are using this medication. For the adjunctive epilepsy population, the incidence of fatigue, appeared dose related. TOPAMAX-induced metabolic acidosis can occur at any time during treatment. TOPAMAX treatment can cause metabolic acidosis [see WARNINGS AND PRECAUTIONS]. Like other antiepileptic drugs, TOPAMAX may cause suicidal thoughts or actions in a very small number of people, about 1 in 500. The results of this study indicate that topiramate Cmax increased by 27% and AUC increased by 29% when HCTZ was added to topiramate. The most common ( 2% more frequent than low-dose 50 mg/day TOPAMAX) adverse reactions causing discontinuation were difficulty with memory, fatigue, asthenia, insomnia, somnolence, and paresthesia. Table 8 includes those adverse reactions that occurred in the placebo-controlled trials where the incidence in any TOPAMAX treatment group was at least 3% and was greater than that for placebo patients. A drug-drug interaction study conducted in patients with type 2 diabetes evaluated the steady-state pharmacokinetics of glyburide (5 mg/day) alone and concomitantly with topiramate (150 mg/day). It was also higher than the background prevalence in United States (0.17%) as estimated by the Centers for Disease Control and Prevention (CDC). Keep TOPAMAX in a tightly closed container. The pharmacokinetics of a single dose of haloperidol (5 mg) were not affected following multiple dosing of topiramate (100 mg every 12 hr) in 13 healthy adults (6 males, 7 females). Anticonvulsant. You may report side effects to FDA at 1-800-FDA-1088. TOPAMAX may cause serious side effects including: See What is the most important information I should know about TOPAMAX?. Materials and methods: The change in the mean 4-week migraine headache frequency from baseline to the double-blind phase was -1.3, -2.1, and -2.2 in the TOPAMAX 50, 100, and 200 mg/day groups, respectively, versus -0.8 in the placebo group (see Figure 2). If you stop using this medicine, do not start it again without your doctor's advice. If you are not pregnant or planning to become pregnant, use effective birth control to prevent pregnancy while taking Topamax. If you stop using tamsulosin for several days in a row, do not start it again without your doctor's advice. Keep a list of them to show your healthcare provider and pharmacist each time you get a new medicine. This medicine is available only with your doctor's prescription. Therefore, patients given TOPAMAX concomitantly with another carbonic anhydrase inhibitor should be monitored particularly closely for the appearance or worsening of metabolic acidosis [see CLINICAL PHARMACOLOGY]. Notable changes (increases and decreases) from baseline in systolic blood pressure, diastolic blood pressure, and pulse were observed occurred more commonly in pediatric patients treated with topiramate compared to pediatric patients treated with placebo [see CLINICAL PHARMACOLOGY]. TOPAMAX can cause fetal harm when administered to a pregnant woman. Measurement of baseline and periodic serum bicarbonate during topiramate treatment is recommended. It may harm them. Rapid titration rate and higher initial dose were associated with higher incidences of cognitiverelated dysfunction. Visit the FDA MedWatch website or call 1-800-FDA-1088. What should I avoid while taking TOPAMAX? Do not start a new medicine without talking with your healthcare provider. Reduced topiramate clearance resulted in slightly higher maximum plasma concentration (23%) and AUC (25%) in elderly subjects than observed in young adults. The increase in the incidence of bladder tumors in males and females receiving 300 mg/kg/day was primarily due to the increased occurrence of a smooth muscle tumor considered histomorphologically unique to mice. If the decision is made to continue patients on TOPAMAX in the face of persistent acidosis, alkali treatment should be considered. If a high fever, a fever that does not go away, or decreased sweating develops, call your healthcare provider right away. Metabolic acidosis can happen with or without symptoms. A dosage adjustment is recommended in patients with moderate or severe renal impairment [see DOSAGE AND ADMINISTRATION, CLINICAL PHARMACOLOGY]. Topiramate can increase body temperature and decrease sweating, leading to life-threatening dehydration (especially in children). Subscribe to Drugs.com newsletters for the latest medication news, new drug approvals, alerts and updates. Inform patients about the signs of serious skin reactions. Topiramate is designated chemically as 2,3:4,5- Di-O-isopropylidene--D-fructopyranose sulfamate and has the following structural formula: TOPAMAX Tablets contain the following inactive ingredients: carnauba wax, hypromellose, lactose monohydrate, magnesium stearate, microcrystalline cellulose, polyethylene glycol, polysorbate 80, pregelatinized starch, purified water, sodium starch glycolate, synthetic iron oxide, and titanium dioxide. Topamaxmay cause serious side effects including: Get medical help right away, if you have any of the symptoms listed above. In patients with renal impairment (creatinine clearance less than 70 mL/min/1.73 m2), one-half of the usual adult dose of TOPAMAX is recommended [see Use In Specific Populations, CLINICAL PHARMACOLOGY]. signs of too much ammonia in your blood--vomiting, unexplained weakness, feeling like you might pass out. This drug/food mixture should be swallowed immediately and not chewed. If we combine this information with your protected In patients with or without a history of seizures or epilepsy, antiepileptic drugs, including TOPAMAX, should be gradually withdrawn to minimize the potential for seizures or increased seizure frequency [see Clinical Studies]. The most common (2% more frequent than low-dose 50 mg/day TOPAMAX) adverse reactions resulting in discontinuation were difficulty with concentration/attention, fever, flushing, and confusion. Safety and effectiveness in pediatric patients below the age of 12 years have not been established for the preventive treatment of migraine. This material is provided for educational purposes only and is not intended for medical advice, diagnosis or treatment. Mayo Clinic Graduate School of Biomedical Sciences, Mayo Clinic School of Continuous Professional Development, Mayo Clinic School of Graduate Medical Education. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Do not take tamsulosin with other similar medicines such as alfuzosin (Uroxatral), doxazosin (Cardura), prazosin (Minipress), silodosin (Rapaflo), or terazosin (Hytrin). Table 6 presents the incidence of adverse reactions occurring in at least 3% of adult patients treated with 200 to 400 mg/day TOPAMAX and was greater than placebo incidence. These very young pediatric patients appeared to experience an increased risk for infections (any topiramate dose 12%, placebo 0%) and of respiratory disorders (any topiramate dose 40%, placebo 16%). The risk of suicidal thoughts or behavior was generally consistent among drugs in the data analyzed. You and your healthcare provider should decide if you will continue to take TOPAMAX while you are pregnant. Adverse reactions associated with discontinuing TOPAMAX included somnolence, dizziness, anxiety, difficulty with concentration or attention, fatigue and paresthesia. Two hundred fifty-five patients completed the entire 26-week double-blind phase. Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. Topamax dosage for migraines. Not all possible drug interactions are listed here. If you take TOPAMAX during pregnancy, your baby may be smaller than expected at birth. Topiramate does not influence the binding of sodium valproate. Know how Topamax may affect you before driving or performing other hazardous activities. Generic name: tamsulosin [tam-soo-LOE-sin] Topiramate has anticonvulsant activity in rat and mouse maximal electroshock seizure (MES) tests. -This drug should be administered approximately one-half hour following the same meal each day. Other adverse reactions seen during clinical trials were: abnormal coordination, eosinophilia, gingival bleeding, hematuria, hypotension, myalgia, myopia, postural hypotension, scotoma, suicide attempt, syncope, and visual field defect. SPRINKLE CAPSULES, for oral use. Table 5: Adverse Reactions in the High Dose Group As Compared to the Low Dose Group, in Monotherapy Epilepsy Trial (Study 1) in Adult and Pediatric Patients. (topiramate) The noeffect dose (0.2 mg/kg/day) for pre- and postnatal developmental toxicity in rats is less than the MRHD for epilepsy or migraine on a mg/m2 basis. This metabolic acidosis is caused by renal bicarbonate loss due to carbonic anhydrase inhibition by TOPAMAX. The incidence of a markedly abnormally low serum bicarbonate (i.e., absolute value < 17 mEq/L and >5 mEq/L decrease from pretreatment) in these trials was up to 11%, compared to 2% for placebo. Topiramate is cleared by hemodialysis. Protect from moisture. Body as a Whole-General Disorders: oligohydrosis and hyperthermia [see WARNINGS AND PRECAUTIONS], hyperammonemia, hyperammonemic encephalopathy [see WARNINGS AND PRECAUTIONS], hypothermia with concomitant valproic acid [see WARNINGS AND PRECAUTIONS], Gastrointestinal System Disorders: hepatic failure (including fatalities), hepatitis, pancreatitis, Skin and Appendage Disorders: bullous skin reactions (including erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis) [see WARNINGS AND PRECAUTIONS], pemphigus, Urinary System Disorders: kidney stones, nephrocalcinosis [see WARNINGS AND PRECAUTIONS], Vision Disorders: acute myopia, secondary angle closure glaucoma [see WARNINGS AND PRECAUTIONS], maculopathy. The clinical relevance of this observation has not been established. TOPAMAX can cause hyperchloremic, non-anion gap, metabolic acidosis (i.e., decreased serum bicarbonate below the normal reference range in the absence of chronic respiratory alkalosis). It will not treat a headache that has already begun. Patients who experienced at least three primary generalized tonic-clonic seizures during the baseline phase were randomly assigned to placebo or TOPAMAX in addition to their other AEDs. Most important fact about this drug In most cases, hyperammonemic encephalopathy abated with discontinuation of treatment. There was also an increased incidence of markedly increased hyperammonemia at the 100 mg dose. Data sources include IBM Watson Micromedex (updated 2 Apr 2023), Cerner Multum (updated 17 Apr 2023), ASHP (updated 10 Apr 2023) and others. In general, the adverse reaction profile for TOPAMAX in this population was similar to that of older pediatric patients, although results from the above controlled study and an open-label, long-term extension study in these pediatric patients 1 to 24 months old suggested some adverse reactions/toxicities (not previously observed in older pediatric patients and adults; i.e., growth/length retardation, certain clinical laboratory abnormalities, and other adverse reactions/toxicities that occurred with a greater frequency and/or greater severity than had been recognized previously from studies in older pediatric patients or adults for various indications. The incidence of decreased serum bicarbonate in pediatric trials, for adjunctive treatment of Lennox-Gastaut syndrome or refractory partial-onset seizures was as high as 67% for TOPAMAX (at approximately 6 mg/kg/day), and 10% for placebo. . In comparison, topiramate clearance per kg is greater in pediatric patients than in adults and in young pediatric patients (down to 2 years) than in older pediatric patients. This approach consisted of first showing a similar exposure response relationship between pediatric patients down to 2 years of age and adults when TOPAMAX was given as adjunctive therapy. Some people use Topamax to treat other . Topiramate by itself is not specifically approved by the FDA for weight loss, but is used in an "off-label" fashion for this condition. The Cambridge Neuropsychological Test Automated Battery (CANTAB) was administered to adolescents (12 to 17 years) to assess the effects of topiramate on cognitive function at baseline and at the end of the Study 13 [see Clinical Studies]. Instruct patients to immediately inform their healthcare provider at the first appearance of skin rash [see WARNINGS AND PRECAUTIONS]. Clinical symptoms of hyperammonemic encephalopathy often include acute alterations in level of consciousness and/or cognitive function with lethargy and/or vomiting. However, if a patient is within 6 hours of taking the next scheduled dose, tell the patient to wait until then to take the usual dose of TOPAMAX, and to skip the missed dose. Topiramate is a white crystalline powder with a bitter taste. Although the effect of TOPAMAX on labor and delivery in humans has not been established, the development of topiramate-induced metabolic acidosis in the mother and/or in the fetus might affect the fetus ability to tolerate labor. Inform patients about the signs of serious skin reactions. Version: 11.01. finasteride, Flomax, tadalafil, prazosin, doxazosin, Cialis. As in adults, hepatic enzyme-inducing antiepileptic drugs decrease the steady state plasma concentrations of topiramate. TOPAMAX can increase the level of acid in your blood (metabolic acidosis). Serious eye problems include: TOPAMAX may cause decreased sweating and increased body temperature (fever). Closely monitor TOPAMAX-treated patients, especially pediatric patients, for evidence of decreased sweating and increased body temperature, especially in hot weather. Avoid driving or hazardous activity until you know how this medicine will affect you. Markedly abnormally low serum bicarbonate values indicative of metabolic acidosis were reported in topiramate-treated pediatric migraine patients [see WARNINGS AND PRECAUTIONS]. Taking topiramate during pregnancy may increase the risk of cleft lip and/or cleft palate, a birth defect that can develop early in pregnancy even before you know you are pregnant. Many adverse reactions shown in Table 9 indicate a dose-dependent relationship. In four, fixed-dose, double-blind clinical trials for the preventive treatment of migraine in TOPAMAX-treated pediatric patients 12 to 17 years of age, the most common adverse reactions with TOPAMAX 100 mg that were seen at an incidence higher (5%) than in the placebo group were: paresthesia, upper respiratory tract infection, anorexia, and abdominal pain (see Table 9).
