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

A severe allergic reaction is known as anaphylaxis, and generally 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 () and act out first aid.

The symptoms of anaphylaxis are:

  1. difficult/noisy breathing
  2. swelling of the tongue
  3. dizziness or collapse
  4. swelling/tightness of the throat
  5. difficulty talking/hoarse voice
  6. wheezing or coughing
  7. pale and floppy (especially young children)

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

The Australasian Society of Clinical Immunology and Allergy recommends 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-istered 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 generally a side-effect of the medicine, rather than an allergic reaction.

Your doctor can generally diagnose allergic reactions to antibiotics by talking to you.

He or she may refer you to an allergy specialist, who may enquire for skin allergy and blood tests.

If you own any other concerns about antibiotics, including possible side effects, contact your doctor.

Signs of a reaction

Dealing with allergies is tough.

More than 50 million Americans own some type of allergy, according to the American College of Allergy, Asthma and Immunology. Most of the time, the body responds to outdoor and indoor allergens with mild reactions, such as a runny nose or sneezing. Sometimes, the reaction is more severe, such as stomach cramps, dizziness or difficulty breathing. But some people with allergies react in more unusual ways. Here are 7 particularly strange symptoms people own developed during an allergic reaction.

Skin tumors

Some people whoget permanent tattoosdevelop strange skin growths.

In , University of Maryland researchers reported a case of a year-old man who developed a skin tumor one month after getting a tattoo. In another study, published in in the Journal of Cutaneous Pathology, researchers analyzed eight people of tattoo-related skin tumors, and found that red tattoo ink was associated with most of the skin tumors. Experts tell the skin recognizes the red ink as a foreign substance, and triggers an immune response.

Blisters, hives and swollen skin — from the sun

There are people who are allergic to the sun and experience symptoms such as blisters, hives and swelling of the skin when they’re exposed to it.

According to a study from researchers in Germany, about 10 to 20 percent of people in Europe, United States and Scandinavia suffer from a sun allergy. The abnormal reaction to sunlight is generally due to ultraviolet rays, according to the Mayo Clinic.

Black spots on the skin

An itchy rash may be a common allergic reaction topoison ivyor poison oak, but there are also rare cases where people develop black spots, according to a study published in the journal Dermatitis.

Black shiny deposits form on the skin and clothing when a high quantity of resin, the toxic plants’ oily secretion, is exposed to the air.

The researchers said the spots eventually peel off, and the skin heals without scarring.

An strange, itchy rash

An year-old boy developed an itchy rash on his abdomen and under his wristwatch a week after he was fitted for his braces, according to a case report published in the journal Dermatitis. It turned out, the boy was allergic to the nickel in the braces. The silver-colored metal is often mixed with other metals and is found in coins, jewelry eyeglass frames, key and home fixtures.
