Warnings and Precautions With Amoxil
There are numerous warnings and precautions with Amoxil to be aware of before starting treatment, including information on who should not use the antibiotic. Do not take Amoxil if you are allergic to penicillin or any components of the drug. Tell your healthcare provider if you have kidney disease or phenylketonuria before using Amoxil, as the medicine could cause problems in people with these conditions.
- Kidney disease, such as kidney failure (renal failure)
- A penicillin allergy
- Any other allergies, including allergies to food, dyes, or preservatives.
Also, let your healthcare provider know if you are:
- Pregnant or thinking of becoming pregnant
Make sure to tell your healthcare provider about all other medicines you are taking, including prescription and non-prescription medicines, vitamins, and herbal supplements.
Some warnings and precautions to be aware of with Amoxil include the following:
- Amoxil contains an antibiotic that belongs to the penicillin group of antibiotics. You should not take Amoxil if you are allergic to penicillin. Let your healthcare provider know immediately if you notice any signs of an allergic reaction, such as a rash, itching, hives, wheezing, swelling of the mouth or lips, or difficulty breathing. An allergic reaction to Amoxil can be very dangerous.
- Let your healthcare provider know if you experience bloody or watery diarrhea. While diarrhea is a common side effect of Amoxil, bloody or watery diarrhea may also be a sign of a serious reaction to Amoxil that can occur when certain bacteria (Clostridium difficile) overgrow in the colon. This severe reaction can occur long after you stop taking Amoxil and can be life-threatening.
- Make sure your healthcare provider knows if you have kidney disease, as you may need a lower Amoxil dosage.
- Sometimes, antibiotics (including Amoxil) can cause yeast infections, since they can get rid of "good" bacteria that help protect against yeast infections. Let your healthcare provider know if you develop a vaginal yeast infection or thrush (a yeast infection of the mouth) while taking Amoxil.
- Amoxil should not be used to treat viruses, such as the common cold or the flu. Amoxil is completely ineffective for treating viruses, and such use can lead to bacterial resistance to Amoxil.
- It is very important to take Amoxil exactly as prescribed. Skipping doses or stopping Amoxil too early (even if you feel better) can lead to bacterial resistance to Amoxil.
- Amoxil chewable tablets contain phenylalanine. This is important for people with phenylketonuria, who must monitor their phenylalanine intake. The other Amoxil products do not contain phenylalanine.
- In general, people with a mononucleosis infection ("mono") should not take Amoxil, since doing so increases the risk of developing a rash.
- Amoxil can interact with other medications (see Drug Interactions With Amoxil).
- Amoxil is considered a pregnancy Category B medication. This means that Amoxil is probably safe for use during pregnancy, although the full risks are not known. Talk to your healthcare provider about the risks and benefits of using Amoxil during pregnancy (see Amoxicillin and Pregnancy for more information).
- Amoxil passes through breast milk. Therefore, if you are breastfeeding or plan to start, be sure to talk with your healthcare provider about using Amoxil (see Amoxicillin and Breastfeeding for more information).
