Topamax (topiramate) General Information
Weight No More – Effective, physician-supervised weight-management solutions
Main Indication For Use:
Migraine prevention and as adjunctive therapy in children and adults with partial onset seizures or primary generalized tonic-clonic seizures.
Most common and not dose related were somnolence (sleepiness,) dizziness, ataxia (loss of balance,) psychomotor slowing, difficulty with memory, paresthesias (numbness and tingling sensation involving extremities,) “metallic” taste in mouth.
Dose Related Side Effects:
Include fatigue, nervousness, and difficulty with concentration, anorexia, weight decrease.
Increased incidence of kidney stones (1.5%) = @ 2-4 times expected at doses above 300mg/day. Higher in men vs. women. High fluid intake to prevent dehydration should decrease this risk.
Do not use with diamox (acetazolamide,) or in conjunction with a ketogenic (starvation type) diet.
Topamax is in tablet/pill form (25/50/200 mgs)
Dosage – Take in the evening Week 1:
25mg samples (1)
¼ of 200mg tab = 50mg
¼ of 200mg tab + 25mg sample = 75mg
½ of 200mg tab = 100mg
Topamax has been used in over 1 million patients and has been on the market for 8 years. The “off label” use of Topamax for chronic pain syndromes, bipolar illness and obsessive compulsive disorders, exceeds its “on label” indication as adjunctive treatment for partial complex seizures.
Topamax has been used safely down to the age of two.
Johnson and Johnson are currently conducting studies evaluating Topamax as a weight loss medication. Possible FDA approval in 2 – 3 years.
Topamax may decrease the effectiveness of oral contraceptives; therefore alternative birth control methods are recommended.
If confusion or disorientation occurs, discontinue Topamax (regardless of dose) and contact my office immediately.
If your “distant” vision seems to get worse during the first six weeks of treatment, discontinue and contact my office as soon as possible. (23 case reports from a database of 825,000.)
ADDENDUM TO “APPETITE SUPPRESSANT INFORMED CONSENT”
I have read and understand my doctor’s statements regarding the use of Topamax (topiramate) and its “off label” use for medical weight loss.
I have been fully informed of the increased risk of kidney stones. I will report any adverse side effects to my physician including, but not limited to, somnolence, fatigue, dizziness, nervousness, etc.
I am aware that I will be taking Topamax (topiramate) as an adjunct to appetite suppressant medication and/or antidepressant medication. I will be monitored on a monthly basis or more frequently as medically indicated.
I have had an opportunity to ask questions and have them answered to my satisfaction.
