Who should not take Qsymia?

You should not take the prescription weight-loss drug Qsymia if you are allergic to its active ingredients, phentermine or topiramate, or to any of its other ingredients.

It's also important not to take Qsymia if you take medicines known as monoamine oxidase inhibitors (MAOIs).

You should not take Qsymia if you are pregnant or planning to become pregnant. This medication can cause serious birth defects in a developing fetus, such as cleft lip or palate. You also should not take it if you're breastfeeding, because the medication may pass into breast milk and be harmful for a nursing baby.

You should not take Qsymia if you have a history of glaucoma or hyperthyroidism (overactive thyroid). Also, tell your doctor if you have a history of any of the following:
  • alcohol or drug problems
  • thoughts about harming or killing yourself or planning or trying to do so
  • mental illness such as depression or hallucinations
  • lung, liver or kidney disease
  • diabetes
  • heart disease
  • high or low blood pressure
  • anorexia or other eating disorder
