How Does Qsymia Work?

Qsymia, which comes in the form of an extended-release capsule, is made with a combination of the medications phentermine and topiramate. Phentermine is an appetite suppressant, which effectively decreases your appetite to encourage reduced caloric intake. Topiramate is typically used as an anticonvulsant medication for people suffering from seizures. In addition to decreasing the appetite, Qsymia can work by increasing the amount of energy used by the body or affecting certain parts of the brain.

How Much Weight Can You Lose With Qsymia?

In clinical studies, patients taking Qsymia for 56 weeks have lost an average of between 24 and 32 lbs. The specific amount of weight you lose will depend on your dosage, your starting weight, and for how long you take the medication.

How Soon Can I Expect to Lose Weight?

It will typically take several weeks to start experiencing significant weight loss while taking Qsymia in NYC, Long Island & New Jersey. In clinical studies, patients taking Qsymia had lost an average of 15 lbs after taking the medication for three months.

How Often Is Qsymia Taken?

Qsymia is meant to be taken once per day. Ideally, you should take the medication every morning with or without a meal.
