Allergic Reaction To Antibiotics | HealthInfi

If you are allergic to antibiotics, you get signs and symptoms like a rash, swelling of the face or difficulty breathing.

A severe allergic reaction is known as anaphylaxis, and usually occurs within an hour of taking an antibiotic. A severe allergic reaction is a medical emergency requiring immediate medical attention. You may need to call triple zero (000) and perform first aid.

The symptoms of anaphylaxis are:

• Difficult/noisy breathing
• Swelling of the tongue
• Swelling/tightness of the throat
• Difficulty talking/hoarse voice
• Wheezing or coughing
• Dizziness or collapse
• Pale and floppy (young children)

Sometimes you can get less dangerous symptoms before an anaphylaxis, such as:

• Swelling of the face, lips and/or eyes
• Hives or welts
• Abdominal pain or vomiting

The Australasian Society of Clinical Immunology and Allergy rrecommends that for a severe allergic reaction adrenaline is the initial treatment. If you are allergic to antibiotics you may be instructed by a doctor how to avoid triggers and if severe may instruct you how to use a self administered adrenalin injection such as epipen. The doctor will record the allergy and type of reaction in your notes and electronic health records and will give you an anaphylaxis action plan.

Most allergies are caused by penicillin or antibiotics closely related to penicillin, or by another type of antibiotic called sulfonamides. Feeling nauseous and vomiting after taking antibiotics is usually a side-effect of the medicine, rather than an allergic reaction. Your doctor can usually diagnose allergic reactions to antibiotics by talking to you. He or she may refer you to an allergy specialist, who may ask for skin allergy and blood tests. If you have any other concerns about antibiotics, including possible side effects, contact your doctor. Nowadays, several thousands of medications for different diseases treatment are used worldwide. Despite proven efficiency and safety of these drugs, they can cause some unusual reactions.

Thus, 15% of all side effects of drug therapy are allergic reactions.

Several types of drugs provoke allergic reactions more than any other drugs do, these are:

• Antibiotic substances (up to 55%)
• Nonsteroidal anti-inflammatory drugs (up to 25%)
• Sulfanilamides (up to 10%)
• Vaccines, vitamins, enzymes (up to 10%)

Allergic reaction to antibiotics is a natural reaction of the body to medication or its metabolites. The severity and frequency of allergic reaction depend on dosage of antibiotics and time people use them.

Usually, a single or preventive application of antibiotics does not cause side effects. A long-term parenteral use of high doses of antibiotics (like injections) increases the risk of allergic reaction.

The majority of allergic reactions to antibiotics have similar signs:

• Occur in small number of people
• Develop quickly in repeated administration of an allergen
• Appear when using antibiotics with identical chemical structure

If a patient has allergic reaction to antibiotics, he should stop using the drug and determine the cause of this reaction. Hypersensitivity to antibiotics occurs either on the active pharmaceutical ingredient, or on excipients. If allergic reaction is caused by the active substance, then you need to use other antibiotic.Read More
