POSSIBLE SIDE EFFECTS

The most common side effects of JANUVIA include:

  • Upper respiratory infection
  • Stuffy or runny nose and sore throat
  • Headache

JANUVIA may occasionally cause stomach discomfort and diarrhea.

When JANUVIA is used in combination with another type of diabetes medicine known as a sulfonylurea, low blood sugar (hypoglycemia) due to the sulfonylurea can occur. Your doctor may prescribe lower doses of the sulfonylurea medicine.

The following additional side effects have been reported in general use with JANUVIA:

  • Allergic reactions, which may be serious, including rash, hives, and swelling of the face, lips, tongue, and throat that may cause difficulty in breathing or swallowing. If you have an allergic reaction, stop taking JANUVIA and call your doctor right away. Your doctor may prescribe a medication to treat your allergic reaction and a different medication for your diabetes.

Tell your doctor if you have any side effect that bothers you or that does not go away.

Other side effects may occur when using JANUVIA. For more information, ask your doctor.

JANUVIA (jah-NEW-vee-ah) is a once-daily prescription pill that, along with diet and exercise, helps lower blood sugar levels in adults with type 2 diabetes.

Important Information About JANUVIA

JANUVIA has not been studied with insulin and should not be used to treat patients with type 1 diabetes or diabetic ketoacidosis (increased ketones in the blood or urine) or used if you are allergic to JANUVIA. Your doctor may perform blood tests from time to time to measure how well your kidneys are working. If you have kidney problems, your doctor may prescribe lower doses of JANUVIA.

When JANUVIA is used with a sulfonylurea, low blood sugar (hypoglycemia) can occur. To avoid this risk, your doctor may prescribe lower doses of the sulfonylurea.

Allergic reactions, which may be serious, including rash, hives, and swelling of the face, lips, tongue, and throat that may cause difficulty breathing or swallowing, can occur. If you have an allergic reaction, stop taking JANUVIA and call your doctor right away. The most common side effects include upper respiratory tract infection, stuffy or runny nose and sore throat, and headache.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch, or call 1-800-FDA-1088.
