Allergic reaction to Antibiotics. Symptoms.

Antibiotic allergy.

Allergic reactions to antibiotics largely depend upon the type and quantity of antibiotics taken. In most cases, symptoms of antibiotic allergy start within 24 hours. How long does an allergic reaction last is often the first question that comes to mind when one starts to develop allergies. It usually lasts for a couple of hours after taking immediate treatment. Following symptoms are observed in case of antibiotic allergy.

Painful rashes either in a simple form or as hives
Redness, swelling and itching
Mild fluid eruptions
Difficulty in breathing
Coughing and wheezing
Trouble in swallowing food
Nausea and vomiting
Anaphylactic shock is a very serious allergic reaction that needs immediate medical attention. It could prove to be fatal, if one is not stabilized and given appropriate medical care.

Allergic reactions to antibiotics in children are also similar to the ones mentioned above. They can develop bouts of diarrhea and abdominal discomfort as well. Amoxicillin and ampicillin are two common antibiotics prescribed to young children which can cause allergic reactions. Parents must restrain from giving children and infants antibiotics without prescription, and must inform the doctor in case an allergic reaction is observed. Other antibiotics that can cause an allergy include penicillin, tetracycline, chloramphenicol, sulphonamides (sulfa drugs), vancomycin, nitrofurantoin, ciprofloxacin, etc.
