Biaxin XL Oral Side Effects

Diarrhea, nausea, vomiting, stomach upset, changes in taste, and headache may occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.

A tablet may rarely appear in your stool. This is more likely to occur if you have certain intestinal disorders (e.g., ileostomy, colostomy, diarrhea). Contact your doctor or pharmacist for further instructions.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor immediately if any of these unlikely but serious side effects occur:

hearing loss
mental/mood changes

Seek immediate medical attention if any of these rare but very serious side effects occur:

persistent nausea/vomiting
severe stomach/abdominal pain

This medication may rarely cause a severe intestinal condition (pseudomembranous colitis) due to resistant bacteria. This condition may occur while receiving therapy or even weeks after treatment has stopped. Do not use anti-diarrhea products or narcotic pain medications if you have the following symptoms because these products may make them worse. Tell your doctor immediately if you develop:

persistent diarrhea
abdominal or stomach pain/cramping
blood/mucus in your stool

Use of this medication for prolonged or repeated periods may result in oral thrush or a new vaginal yeast infection (oral or vaginal fungal infection). Contact your doctor if you notice white patches in your mouth, a change in vaginal discharge or other new symptoms.
