Is taking an ibuprofen a few times a week bad for the body?

Side effects: All medications have side effects. Taking any nsaid, like ibuprofen, with frequency over extended periods of time can increase your chances of long term side effects like gastrointestinal inflammation/irritation and possible kidney problems. If you are taking this frequently for a short period with food you should be ok but i would try to limit your exposure and take only when absolutely necessary.

Not usually: Ibuprofen when used occasionally is a very safe medication.
