Allergy Symptoms

• The symptoms of an allergic reaction to amoxicillin are serious and require medical attention immediately. Please make sure to seek treatment or go to the ER when these symptoms begin. The symptoms of an allergic reaction are hives, trouble breathing, and swelling of face, tongue, lips or throat.
  
  

Physical Interactions

• You may also want to inform your doctor if you have liver disease, kidney disease, asthma, a bleeding or blood clotting problem, mononucleosis, a history of any type of allergy or a history of diarrhea caused by taking antibiotics.
  
  

Drugs Interactions

• Because amoxicillin is in the penicillin family of drugs, an allergic reaction will occur if you ingest any drugs that contain penicillin. Drugs with penicillin to avoid are drugs such as cephalosporins antibiotics, ampicillin, carbenicillin, dicloxacillin, oxacillin and, of course, penicillin. It is important to tell your doctor if you have previously experienced allergic reactions to any of these antibiotics.
  
  

Pregnancy Interactions

• Amoxicillin has the ability to lessen the effectiveness of birth control and can result in pregnancy. While amoxicillin is safe to use during pregnancy, it can be secreted in breast milk and harm a nursing baby. The best recommendation is to not use amoxicillin while breast feeding.
  
  

Phenylalanine Interactions

• The chewable tablets of Amoxicillin may contain phenylalanine. If you are phenylketonuric or PKU, meaning that your liver cannot produce a specific type of PAH enzyme, you should not take the chewable tablets. The lack of PAH builds up high levels of phenylalanine in the brain and blood which are toxic to the nervous system and cause irreversible damage to the brain. Phenylalanine can cause deformities and birth defects in growing fetuses.
  
  

Conclusion

• Always tell your doctor concerns you have or problems you have had in the past with particular antibiotics; this may lead to the discovery of a previously unknown allergy. The knowledge of having an amoxicillin allergy may save you from pain or even fatal reactions.
