Amoxicllin is a very popular and useful antibiotic that is a derivative of penicillin. Amoxicillin is in fact known as an "aminopenicillin" and is effective against many more strains of bacteria than penicillin is. Amoxicillin is used to treat many different types of infections including upper respiratory tract infections and urinary tract infections. While typically well tolerated, amoxicillin can cause side effects and unwanted adverse reactions. The most significant of these side effects is actually a type allergy known as a hypersensitivity reaction. We will discuss this and the other possible side effects below. Hypersensitivity reactions are the most common adverse reactions in patients taking penicillin type drugs. Amoxicillin is a prescription medication used to treat certain bacterial infections such as pneumonia, bronchitis, gonorrhea, and certain types of ulcers. It can also treat bacterial infections of the ears, nose, throat, urinary tract, and skin. This medication belongs to a group of drugs called penicillin antibiotics, which work by blocking the growth of bacteria. Amoxicillin comes as a capsule, tablet, and oral suspension forms. This medication is taken up to 3 times daily, with or without food. Common side of amoxicillin effects include nausea, vomiting, diarrhea, and headache. This is not a complete list of amoxicillin side effects.

CONTRAINDICATIONS — Hypersensitivity to amoxicillin, penicillin, other beta-lactams, or any component of the formulation. WARNINGS / PRECAUTIONS Concerns related to adverse effects. Case Description. A 62-year-old male heart transplant candidate due to complicated coronary artery disease presented with a previous anaphylactic reaction. Amoxicillin is a semisynthetic (synthesized from naturally occurring substance) aminopenicillin antibiotic structurally related to ampicillin. It is a moderate-spectrum antibiotic active against a wide range of Gram-positive, and limited number of Gram-negative bacteria. Amoxicillin was discovered by scientists at Beecham Research Laboratories in 1972. In the US it is marketed by Glaxo Smith Kline (the inheritor company) under the original trade name Amoxil. The narrow antimicrobial spectrum of penicillins, led to the search for derivatives of penicillin which could treat a wider range of infections. The first important step forward was the development of ampicillin. Ampicillin had a broader spectrum of activity than either of the original penicillins and allowed doctors to treat a broader range of both Gram-positive and Gram-negative infections. Drug hypersensitivity is an immune-mediated reaction to a drug. Symptoms range from mild to severe and include rash, anaphylaxis, and serum sickness. Diagnosis is clinical; skin testing is occasionally useful. Treatment is drug discontinuation, supportive treatment (eg, with antihistamines), and sometimes desensitization., therapeutic antibodies) can directly stimulate antibody production. However, most drugs act as haptens, binding covalently to serum or cell-bound proteins, including peptides embedded in major histocompatibility complex (MHC) molecules. The binding makes the protein immunogenic, stimulating antidrug antibody production, T-cell responses against the drug, or both. Haptens may also bind directly to the MHC II molecule, directly activating T cells. When metabolized, prohaptens become haptens; eg, penicillin itself is not antigenic, but its main degradation product, benzylpenicilloic acid, can combine with tissue proteins to form benzylpenicilloyl (BPO), a major antigenic determinant.
