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. Healthcare providers and patients should report all cases of
pregnancy to FDA MedWatch at 1‑800‑FDA‑1088, and the Qsymia Pregnancy Surveillance Program at 1‑888‑998‑4887.
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). These problems can lead to permanent
vision loss if not treated. Tell your healthcare provider right away if you have any new eye symptoms.
Possible side effects of Qsymia include:
Mood changes and trouble sleeping. Qsymia may cause depression or mood problems, and trouble sleeping. Tell your
healthcare provider if symptoms occur.
Concentration, memory, and speech difficulties. Qsymia may affect how you think and cause confusion, problems with
concentration, attention, memory or speech. Tell your healthcare provider if symptoms occur.
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.
High blood pressure medicines. If you are taking medicines for your blood pressure, your doctor may need to adjust these
medicines while taking Qsymia.
Central Nervous System (CNS) side effects. The use of prescription sleep aids, anxiety medicines, or drinking alcohol with
Qsymia may cause an increase in CNS symptoms such as dizziness and light-headedness. Do not drink alcohol with Qsymia.
Possible seizures if you stop taking Qsymia too fast. Seizures may happen in people who may or may not have had seizures in
the past if you stop Qsymia too fast. Your healthcare provider will tell you how to stop taking Qsymia slowly.
Kidney stones. Drink plenty of fluids when taking Qsymia to help decrease your chances of getting kidney stones. If you get
severe side or back pain, and/or blood in your urine, call your healthcare provider.
Decreased sweating and increased body temperature (fever). People should be watched for signs of decreased sweating and
fever, especially in hot temperatures. Some people may need to be hospitalized for this condition.
Common side effects of Qsymia include:
Numbness or tingling in the hands, arms, feet, or face (paraesthesia); dizziness; changes in the way foods taste or loss of taste
(dysgeusia); trouble sleeping (insomnia); constipation; and dry mouth.
