Qsymia is a weight loss prescription drug that is made up of immediate-release Phentermine and extended-release Topiramate. Phentermine is an appetite suppressant which makes you eat less.
This helps you to take in fewer calories every day which helps you to lose weight. Topiramate is a seizure drug (anticonvulsant) that helps you to feel full also helping you to eat less. Qsymia is used in conjunction with a low calorie diet and exercise as a chronic weight management program for obese individuals.
Depending on you body mass index (BMI), Qsymia is prescribed differently to be determined by your doctor. Generally, treatment starts with Qsymia (3.75 mg Phentermine and 23 mg Topiramate) daily for 14 days. Then the dose is increased to Qsymia 7.5 mg/46 mg once a day. Then, initial weight loss is determined 12 weeks (3 months) after the starting point.
Below is a list of possible Qsymia side effects and this is by no means a complete list so other symptoms are possible so keep that in mind.
