What should I watch for while taking Zithromax?
Tell your prescriber or health care professional if your symptoms do not improve in 2 to 3 days. Contact your prescriber or health care professional as soon as you can if you get an allergic reaction to azithromycin, such as rash, itching, difficulty swallowing, or swelling of the face, lips or tongue. Keep out of the sun, or wear protective clothing outdoors and use a sunscreen. Do not use sun lamps or sun tanning beds or booths. If you get severe or watery diarrhea, do not treat yourself. Call your prescriber or health care professional for advice. Antacids can stop azithromycin from working. If you get an upset stomach and want to take an antacid, make sure there is an interval of at least 2 hours since you last took azithromycin, or 4 hours before your next dose. If you are going to have surgery, tell your prescriber or health care professional that you are taking azithromycin.
