If your or your child's symptoms do not improve within a few days, or if they become worse, check with your doctor.

This medicine may cause a serious allergic reaction called anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention. Call your doctor right away if you have a skin rash; itching; shortness of breath; trouble with breathing; trouble with swallowing; or any swelling of your hands, face, mouth, or throat after you or your child receive this medicine.

Amoxicillin may cause diarrhea, and in some cases it can be severe. It may occur 2 months or more after you stop taking this medicine. Do not take any medicine or give medicine to your child to treat diarrhea without first checking with your doctor. Diarrhea medicines may make the diarrhea worse or make it last longer. If you have any questions about this or if mild diarrhea continues or gets worse, check with your doctor.

Before you have any medical tests, tell the doctor in charge that you or your child are taking this medicine. The results of some tests may be affected by this medicine.

In some young patients, tooth discoloration may occur while using this medicine. The teeth may appear to have brown, yellow, or gray stains. To help prevent this, brush and floss your teeth regularly or have a dentist clean your teeth.

Birth control pills may not work while you are using this medicine. To keep from getting pregnant, use another form of birth control along with your birth control pills. Other forms include a condom, a diaphragm, or a contraceptive foam or jelly.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
