Brief Answer: Dose prescribed based on protocol ma'am Detailed Answer: Hello ma'am and welcome. Thank you for writing to us. Topamax is usually not calculated taking into consideration weight and height ma'am. There is a fixed protocol by which we prescribe the medication. It is as follows: -25 mg/day for the first week, usually a morning dose -Increased by 25 mg/day the following week -Then increased by 50 mg/day the following weeks This increase in dosage is only advised in those patients, in whom a response is not achieved. The dose is careful titrated and altered based on the patients response and individual requirement. In patients taking a dosage of higher than 50 mg/day, the dosage is also split into morning and night dosages (eg. 50 mg in the morning, and 25 mg at night). In your case, as mentioned in the above regimen, a 25 mg/day dose would be recommended to begin with, but please do consult your doctor for the same. As for the side effects, a maximum dosage of 400 mg/day is recommended, beyond which side effects, dependence or toxicity is seen. It is highly recommended for you not to self-prescribe and to only take the dosage recommended by your health care provider. I hope you find my response both helpful and informative ma'am. Please feel free to write back to me for any further clarifications, I would be more than happy to help you. Best wishes.
