Get emergency medical help if you have signs of an allergic reaction to Uloric (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning in your eyes, skin pain, red or purple skin rash that spreads and causes blistering and peeling).
Seek medical treatment if you have a serious drug reaction that can affect many parts of your body. Symptoms may include: skin rash, fever, swollen glands, flu-like symptoms, muscle aches, severe weakness, unusual bruising, or yellowing of your skin or eyes. This reaction may occur several weeks after you began using Uloric.
Call your doctor at once if you have:
a light-headed feeling, like you might pass out;
heart attack symptoms - chest pain or pressure, pain spreading to your jaw or shoulder, fast heartbeats, shortness of breath;
liver problems - stomach pain (upper right side), unusual tiredness, dark urine, jaundice (yellowing of the skin or eyes); or
signs of a stroke - sudden numbness or weakness (especially on one side of the body), sudden severe headache, slurred speech, problems with vision or balance.
Common Uloric side effects may include:
gout flares, joint pain;
nausea;
mild rash; or
abnormal liver function tests.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
