Advil is a brand name for the nonsteroidal anti-inflammatory drug (NSAID) ibuprofen [1]. It is commonly used to relieve pain, fever, and inflammation caused by various conditions such as headache, toothache, menstrual cramps, arthritis, and others. However, like any medication, Advil may cause side effects, some of which may require medical attention.

Common side effects of Advil include upset stomach, nausea, vomiting, bloating, gas, constipation, diarrhea, dizziness, headache, nervousness, and skin rash [2]. These side effects are usually mild and go away on their own without treatment. However, if they persist or worsen, you should contact your doctor or pharmacist.

Serious side effects of Advil are rare but may occur in some people, especially if they take the medication for a long time or at high doses. These side effects include stomach bleeding, ulcers, liver damage, kidney damage, high blood pressure, heart attack, stroke, and allergic reactions [3]. If you experience any of these side effects, you should seek medical attention immediately.

To treat Advil side effects, you should follow the instructions on the medication label and talk to your doctor or pharmacist if you have any questions or concerns. You may be advised to take Advil with food or milk to reduce stomach upset, avoid alcohol and smoking, and drink plenty of fluids to prevent constipation and dehydration. If you experience skin rash or allergic reactions, you should stop taking Advil and seek medical attention.

In summary, Advil is a commonly used NSAID that may cause side effects, both common and serious. To treat Advil side effects, you should follow the medication label instructions, talk to your doctor or pharmacist, and seek medical attention if necessary.
