QSYMIA CAN CAUSE SERIOUS SIDE EFFECTS, INCLUDING:
Birth defects (cleft lip/cleft palate). If you take Qsymia during pregnancy, your baby has a higher risk for birth defects called cleft lip and cleft palate. These defects can begin early in pregnancy, even before you know you are pregnant. Women who are pregnant must not take Qsymia. Women who can become pregnant should have a negative pregnancy test before taking Qsymia and every month while taking Qsymia and use effective birth control (contraception) consistently while taking Qsymia. Talk to your healthcare provider about how to prevent pregnancy. If you become pregnant while taking Qsymia, stop taking Qsymia immediately, and tell your healthcare provider right away.
Increases in heart rate. Qsymia can increase your heart rate at rest. Your healthcare provider should check your heart rate while you take Qsymia. Tell your healthcare provider if you experience, while at rest, a racing or pounding feeling in your chest lasting several minutes when taking Qsymia.
Suicidal thoughts or actions. Topiramate, an ingredient in Qsymia, may cause you to have suicidal thoughts or actions. Call your healthcare provider right away if you have any of these symptoms, especially if they are new, worse, or worry you: thoughts about suicide or dying; attempts to commit suicide; new or worse depression; new or worse anxiety; feeling agitated or restless; panic attacks; trouble sleeping (insomnia); new or worse irritability; acting aggressive, being angry, or violent; acting on dangerous impulses; an extreme increase in activity or talking (mania); other unusual changes in behavior or mood.
Serious eye problems, which include any sudden decrease in vision, with or without eye pain and redness or a blockage of fluid in the eye causing increased pressure in the eye (secondary angle closure glaucoma).

Increases of acid in bloodstream (metabolic acidosis). If left untreated, metabolic acidosis can cause brittle or soft bones (osteoporosis, osteomalacia, osteopenia), kidney stones, can slow the rate of growth in children, and may possibly harm your baby if you are pregnant. Metabolic acidosis can happen with or without symptoms. Sometimes people with metabolic acidosis will: feel tired, not feel hungry (loss of appetite), feel changes in heartbeat, or have trouble thinking clearly. Your healthcare provider should do a blood test to measure the level of acid in your blood before and during your treatment with Qsymia.
Low blood sugar (hypoglycemia) in people with type 2 diabetes mellitus who also take medicines used to treat type 2 diabetes mellitus. Weight loss can cause low blood sugar in people with type 2 diabetes mellitus who also take medicines used to treat type 2 diabetes mellitus (such as insulin or sulfonylureas). You should check your blood sugar before you start taking Qsymia and while you take Qsymia.
