Topiramate (Topamax) is a medicine that is usually used to control
seizures. However, recent studies found that it may be
effective in controlling binging and reducing weight in people who have
binge eating disorder and obesity.1
This medicine lowers some people's appetites. It is not clear how
topiramate helps with weight loss, but experts believe that it affects brain
chemicals called
neurotransmitters.
Side effects usually are temporary but can include:
- Sleepiness.
- Dizziness.
- Loss of
appetite and weight loss.
- Nervousness.
- Difficulty
concentrating and paying attention.
- Problems with
speech.
- Memory problems.
- Aggressiveness or
agitation.
- Changes in sensation, such as touch, smell, or
taste.
- Vision problems, such as blurred or double vision.
Topiramate can cause other rare side effects, including:
- Changes in blood chemistry. If you take this
medicine, you may need periodic tests of the bicarbonate levels in your
blood.
- Vision problems and glaucoma (a serious condition that
causes increased pressure inside the eye).
- Decreased sweating and
increased body temperature, especially in hot weather. This may be especially
true for children.
- An increased risk of becoming pregnant while
using birth control pills.
- An increased possibility of kidney
stones.
