What times can I safely take OTC Tylenol and Advil?

Advil (ibuprofen)

Ask a doctor or pharmacist if this medicine is safe to use if you have ever had:

heart disease, high blood pressure, high cholesterol, diabetes, or if you smoke;

a heart attack, stroke, or blood clot;

stomach ulcers or bleeding;

liver or "kidney disease;"

asthma; or

if you take aspirin to prevent heart attack or stroke.

Tylenol (acetaminophen), does not have warnings as Advil (ibuprofen, regarding kidney disease).

Although you are taking OTC meds, as you have read they do have potential side effects, risks and warnings, do not self medicate.

I suggest you see a DR. when you are able to (sooner than later) and have him/her prescribe a safe an effective pain medication given your kidney disease.
