How to Remove Sulfa Allergic Reactions Caused on the Body?

What is Sulfa Allergy?

What are the Causes of Sulfa Allergies?

The factors causing sulfa allergy should be well recognised in order to treat such adverse effects and reduce their risk. The major causes of sulfa allergies are listed below.

Causes Description
Sulfamethoxazole-trimethoprim It is a frequently used antibiotic. It is a common drug which causes allergy in people who are sensitive to sulfa drugs.
Erythromycin-sulfisoxazole This medication is given to patients suffering from bacterial infections, and most of the drugs are given to children. 
Sulfasalazine Medications for conditions such as rheumatoid arthritis and ulcerative colitis. It contains sulfa, which can trigger allergies.
Dapsone An antibiotic used for leprosy and dermatitis herpetiformis in a primarily off-label use. Such antibiotics can be allergic.
Furosemide A diuretic for oedema and high blood pressure. It has sulfa, and this may lead to allergic reactions in some patients.
Acetazolamide A drug used for the treatment of seizures, altitude sickness, and ophthalmic applications. It contains sulfa products that may be allergic to people.
Thiazide Diuretics Diuretics to reduce arterial blood pressure and decubital oedema. These drugs do contain sulfonamides and induce allergies.
Sulfonylureas Drugs intended for the treatment of type 2 diabetes mellitus. The medications contain sulfa, and they can cause reactions in people with sulfa allergy.

What are the Symptoms of Sulfa Allergies?

Symptoms Description
Skin Rash This occurs when sulfa drugs are taken as soon as possible after mild redness. Minimal redness or severe blush may occur.
Hives Raised, red, burning lumps on the skin are acquired normally when taking a sulfa drug and occur instantly.
Itchy Skin or Eyes Sustained intense scratching of the skin or the eye may be observed when taking sulfa drug as an allergy.
Breathing Problems Hoarseness, harsh sounds when exhaling, and trouble relaxing are signs of a dangerous prosthetic allergy.
Swelling of Face Hives are welts that appear with rapid relation to treatment and, most commonly, include lips with spreading areas of swelling.
Fever Among the symptoms is a fever, a strong indication of a system allergy reaction to sulfa drugs.
Joint pain Also, flu symptoms, such as joint pain and swelling, may usually appear if a more serious sulfa allergy treatment is involved.
Anaphylaxis A life-threatening allergic reaction that causes severe breathing difficulties, rapid heartbeat, and loss of consciousness. 

Furthermore, there are several serious skin reactions occurring due to sulfa allergy. They are listed below.

Serious Skin Reactions Description
Sulfonamide Drug Hypersensitivity Syndrome Symptoms include a fever and rash that progress to organ malfunction. This acute type of hypersensitivity often involves two or more systems and may need medical care.
Drug Eruption Patches on the skin appear to be round, red, and swollen. This type of hypersensitivity causes discomfort, and the drug implicated may have to be stopped.
Stevens-Johnson Syndrome Severe dermal symptoms comprise blisters and sloughing of affected areas. This condition is characterised by the destruction of the skin and mucous membranes or both.

How to Diagnose Sulfa Allergies?

Diagnostic Method Description
Medical History Review The doctor assesses the likelihood of a reaction using any past reactions, current signs and a history of taking sulfa drugs.
Skin Prick Test Alcohol, sulfa hormones, sulfa amides or other known sulfa drugs are tested topically for rapid allergy tests on patients.
Blood Test Serological tests help extend the diagnosis of sulfa allergies by measuring the antibodies against sulfa products. 
Patch Test The most common reason is delayed patch testing with sulfonamides to induce allergic contact dermatitis.
Drug Challenge Test A patch test was also done to assess the risk by submitting a provocation test, confirming the standing allergy diagnosis.
Elimination Diet Foods that include sulfa were eliminated from the diet, and symptoms were improved, which assisted in diagnosing food allergies.
Challenge Test Permitted under the watchful eye of a physician, this test places the miprim sulfa drug or presumed causative sulfa drug.
Immunologic Testing Rather than basophil activation tests or enzyme-linked immunosorbent assays were employed to deal with the allergy.
