The white round pill with the imprint G 25 has been identified as Topiramate 25 mg supplied by Glenmark Generics Inc.. Topiramate is in a class of medications called anticonvulsants. It works by decreasing abnormal excitement in the brain.
G 25 pill is used alone or with other medications to treat certain types of seizures including primary generalized tonic-clonic seizures (formerly known as a grand mal seizure; seizure that involves the entire body) and partial onset seizures (seizures that involve only one part of the brain). G 25 pill is also used with other medications to control seizures in people who have Lennox-Gastaut syndrome (a disorder that causes seizures and developmental delays). G 25 pill is also used to prevent migraine headaches but not to relieve the pain of migraine headaches when they occur.
There have not been any studies on whether topiramate can cause dependence, but it may be possible. Unlike many other drugs of abuse, topiramate won’t make you feel high. Instead, you’re more likely to feel sleepy, dazed, or a little bit confused. It won’t produce feelings of pleasure, excitement, or happiness.
How should I take G 25 pill?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed. G25 pill can be taken with or without food.
Swallow the tablet whole and do not crush, chew, or break it. Carefully follow the swallowing instructions for your medicine.
G25 pill doses are sometimes based on weight in children. Your child’s dose needs may change if the child gains or loses weight. Drink plenty of liquids while you are taking G25 pill, to prevent kidney stones or an electrolyte imbalance.
You will need frequent medical tests. If you need surgery, tell the surgeon ahead of time that you are using G25 pill. Any medical care provider who treats you should know that you take seizure medication.
Do not stop using G 25 pill suddenly, even if you feel fine. Stopping suddenly may cause increased seizures. Follow your doctor’s instructions about tapering your dose.
Call your doctor if your seizures get worse or you have them more often while taking G25 pill.

Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
• tell your doctor if you or any family members have or have ever had kidney stones, and if you have ever thought about killing yourself or tried to do so.

Also tell your doctor if you have diarrhea or if you develop diarrhea during your treatment.
• tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you are pregnant or plan to become pregnant, your doctor may prescribe a different medication instead of topiramate because topiramate may harm the fetus. If you do not plan to become pregnant, you should use birth control to prevent pregnancy during your treatment with topiramate. Talk to your doctor about what type of birth control you should use, because taking topiramate may decrease the effectiveness of some types of birth control.

Avoid exposure to heat, drink plenty of fluids and tell your doctor if you have a fever, headache, muscle cramps, or an upset stomach, or if you are not sweating as usual.
• you should know that you may be more likely to develop a kidney stone while you are taking G 25 pill. Drink 6 to 8 glasses of water every day to prevent kidney stones from forming.
• you should know that your mental health may change in unexpected ways and you may become suicidal (thinking about harming or killing yourself or planning or trying to do so) while you are taking G 25 pill for the treatment of epilepsy, mental illness, or other conditions.

Some of these people developed suicidal thoughts and behavior as early as 1 week after they started taking the medication.
