Voltaren Gel side effects
Get emergency medical help if you have any of these signs of an allergic reaction to Voltaren Gel: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
Although the risk of serious side effects is low when diclofenac is applied to the skin, you should be aware of side effects that can occur if the medication is absorbed into your bloodstream.
Stop using Voltaren Gel and call your doctor at once if you have a serious side effect such as:
chest pain, slurred speech, problems with vision or balance, and feeling weak or short of breath;
bloody or tarry stools, coughing up blood or vomit that looks like coffee grounds;
pale or yellowed skin, dark colored urine, confusion;
swelling or rapid weight gain, urinating less than usual or not at all;
nausea, upper stomach pain, itching, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes);
bruising, severe tingling, numbness, pain, muscle weakness;
fever, sore throat, and headache with a severe blistering, peeling, and red skin rash; or
the first sign of any skin rash, no matter how mild.
Less serious Voltaren Gel side effects may include:
mild nausea, stomach pain, upset stomach;
diarrhea, gas; or
mild itching, dryness, redness, scaling, or other skin irritation where the medicine was applied.
