What is Weight Loss?


While a few extra pounds may not seem like a big deal, they can increase your chances of having high blood pressure and high blood sugar. These conditions may lead to serious health problems, including heart disease, stroke, type 2 diabetes, and certain cancers.

Other treatments for Weight Loss







FDA-approved use

For weight loss for adults - Qsymia should be used in combination with a reduced calorie diet and increased exercise

FDA recommends you evaluate weight loss after 12 weeks of treatment. If you have not lost at least 3% of your body weight on Qsymia 7.5mg/46mg, stop Qsymia or increase dose. If you have not lost at least 5% of your body weight after 12 weeks on Qsymia 15mg/92mg, stop Qsymia because it is unlikely to work.

Track record


Medium track record means that new‚ unexpected side effects are possible. Qsymia was approved by FDA in 2012 based on studies where about 2,300 people took approved doses of the drug for 12 months. As with all new drugs, rare but serious side effects may emerge after the drug is on the market when larger numbers of people - with other conditions and on other medications - have used the drug.
