Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, vomiting, or yellow eyes or skin. These could be symptoms of a serious liver problem.

This medicine may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and require immediate medical attention. Call your doctor right away if you have a rash, itching, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth while you are using this medicine.

The tip cap of the prefilled syringe for intramuscular injection contains dry natural rubber (a derivative of latex), which may cause allergic reactions in people who are sensitive to latex. Tell your doctor if you have a latex allergy before you start using this medicine.

This medicine may cause redness, pain, or swelling at the injection site. Some patients have developed serious skin infection or damage (necrosis), including a permanent depression under the skin at the injection site.

If you can, avoid people with infections. Check with your doctor immediately if you think you are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.

Check with your doctor immediately if you notice any unusual bleeding or bruising, black, tarry stools, blood in the urine or stools, or pinpoint red spots on your skin.

Be careful when using a regular toothbrush, dental floss, or toothpick. Your medical doctor, dentist, or nurse may recommend other ways to clean your teeth and gums. Check with your medical doctor before having any dental work done.

Do not touch your eyes or the inside of your nose unless you have just washed your hands and have not touched anything else in the meantime.

Be careful not to cut yourself when you are using sharp objects, such as a safety razor or fingernail or toenail cutters.

Avoid contact sports or other situations where bruising or injury could occur.

This medicine may cause pulmonary arterial hypertension (high blood pressure in the lungs). Check with your doctor right away if you have trouble breathing or unusual tiredness or weakness.
