What is a white pill with I8 on it?
Not Medical Advice: A white pill with an oblong shape or capsule-shaped and imprinted with I8 or 8I (depending on how you are holding it, it reads one way or the other) is a generic version of ibuprofen 800mg, an NSAID (non-steroidal anti-inflammatory drug) most often used in treating headaches; pain including back pain, toothache, muscle pain, and menstrual cramps; and osteoarthritis.
This particular generic version is primarily manufactured by Dr. Reddy's Laboratories Inc. Ibuprofen is widely marketed in its generic form, and also marketed under these brand names: Advil, Nuprin, Motrin, Midol, IBU, and Genpril.
Common side effects of ibuprofen use may include gas or bloating; upset stomach, constipation, mild heartburn, or diarrhea; nervousness, headache, or dizziness; rash or skin itching; ringing in the ears; or blurred version. If you experience any of these common side effects on a persistent basis, you may wish to consult your physician.
According to media reports in early September 2012, a new study published in Circulation (the journal of the American Heart Association) showed that heart attack survivors taking common NSAIDs (painkillers) such as naproxen, ibuprofen, and prescription drugs such as Celebrex after they've had a heart attack show an increased long-term risk of having a second heart attack or death.
