Sulfa drugs can cause allergic reactions in some people, including hives, swelling and difficulty breathing. If you’ve ever experienced a reaction to a sulfa drug, your doctor may have diagnosed you with a sulfa allergy. Inform other treating physicians of this allergy and your medical chart will be flagged with this information. If you’re ever hospitalized, you may wear a bracelet that informs hospital personnel that you have a sulfa allergy. But sulfa drugs and foods that contain sulfites or sulfates aren’t chemically related, so you don’t have to worry about sulfa in your diet.

Sulfa Vs Sulfite Allergy

Sulfa allergies and sulfite allergies arent the same thing. Sulfites occur naturally, or are used as a preservative agent in some foods and drinks. Sulfa medications and sulfites found in food and drink arent related to each other. The similarity between their names can cause some confusion. Read more about the difference between sulfa allergies and sulfite allergies.

Symptoms of sulfa allergy are similar to those of other drug allergies. Symptoms may include:

  • skin rash or hives

What Is The Best Medication For A Rash

What is the best medication for a rash? Because most rashes resolve on their own and arent usually serious, over-the-counter creams that include diphenhydramine , cortisone and topical treatments with camphor can help with itching. If the rash is widespread, oral medication is needed.

What pain medications are known to cause rashes? Check out this roundup of some common medications that can cause rashes: ACE Inhibitors: Captopril Enalopril Fosinopril Lisinopril Anticonvulsants: Carbamazepine Ethosuximide Chlorpromazine Phenytoin Lomotrigene Zonisamide Antibiotics

Natural Wines: A Viable Wine Sulfite Sensitivity Cure

One increasingly popular soloution, that we have spoken about previously on the Sobur blog, is natural, sulfur-free wines.

These natural wines, which are still only a small market, have little or no Sulfur dioxide added. This is easier to do with red wines, because the tannin within the wine acts as a as a natural anti-oxidant. Tannin within the wine means less sulfur dioxide is needed to protect the wine during the winemaking and maturation process.

Sulfa Allergy: Symptoms, Causes, Diagnosis, and Treatment

Elemental sulfur powder is commonly used in gardening, and while irritation may occur from skin contact or inhalation, allergy has not been described.

Sulfates are in some injectable drugs as sulfate compounds, such as heparin sulfate, dextran sulfate, morphine sulfate. The sulfates in soaps are strong detergents and can irritate the skin or eyes. However sulfate itself does not cause allergic reactions. It is usually safe to use a sulfate when a person has a sulfonamide allergy or a sulfite intolerance.

Sulfite preservatives are commonly known as sulfur dioxide and metabisulfites, with preservative numbers 220-228. Sulfites can be used to preserve flavour and colour within food, inhibit bacterial growth, stop fresh food from spoiling, and help preserve medication. Sulfites are most often found in wine, dried fruit, and dried vegetables. Sometimes they are used in sausages and salads. They can also occur naturally in low concentrations. Sulfites can cause adverse reactions which are like allergy but do not involve the immune system and are therefore called intolerances. The most common reactions are asthma symptoms and rhinitis reactions. Occasionally urticaria may occur, and very rarely, anaphylaxis .

There is no relationship between sulfite sensitivity and sulfonamide antibiotic allergy.

    • Saline nasal rinses can be used for congestion-related allergy symptoms.
    • Corticosteroid creams can treat skin rashes related to allergies.
    • Immunotherapy is a long-term treatment option for chronic allergy symptoms.
    • Anaphylaxis is a medical emergency, and people should call 911 if they suspect someone is having an anaphylactic reaction.

    An allergic reaction occurs when cells in the immune system interpret a foreign substance or allergen as harmful.

    The immune system overreacts to these allergens and produces histamine, which is a chemical that causes allergy symptoms, such as inflammation, sneezing, and coughing.

    Mild allergic reactions can usually be treated with home remedies and over-the-counter medications.

    However, chronic allergies need treatment from a medical professional. Severe allergic reactions always require emergency medical care.

    Many mild to moderate allergic reactions can be treated at home or with OTC medications. The following treatments are commonly used to reduce the symptoms of an allergic reaction:

    Drugs To Avoid With Sulfa Allergies

    Sulfa antibiotics have been widely used for more than 70 years. The first antibiotic was a sulfa drug introduced in 1936. Today, these drugs include burn creams, vaginal suppositories, and eye drops as well as medications for many types of infections. If youâve had an allergic reaction to one sulfa antibiotic, youâre probably allergic to all of them.

    Here are a few examples of common sulfa drugs that could cause problems:

    But be sure to tell your doctor if you have a sulfa allergy before taking any of these.

    Important Features Of Sulfa Allergy Rash

    The most commonly visible symptom is the eruption of skin rash. Some people may get hives as well. All these symptoms start showing up soon after the use of the specific medicine that contains sulfonamides.

    As you take the medicine, the immune system responds by releasing histamines and antibodies resulting in this kind of skin reactions. In some cases, the rashes could be mild and in others they can be found all over the body.

    Mild to moderate itching sensation can be felt on these rashes. These rashes are usually extremely sensitive towards light. So, if they get exposed to direct sunlight, they worsen further.

    Generally, the rashes do not come alone and are accompanied by fever. In a serious allergic reaction, more serious symptoms could be observed along with the rash. If the respiratory system is attacked, then it causes wheezing, breathing difficulty, and pneumonia.

    Sometimes, it may result in a decrease of blood cells and platelets in the body. The condition tends to become life-threatening if the symptoms of anaphylaxis are noticed.

    This happens when the tissues inside the throat swell up to such an extent that the air passage gets blocked. It can be identified by shortness of breath, rapid pulse rate, nausea, vomiting, and gradual loss of consciousness.

    What Is A Sulfa Allergy

    Sulfa allergies are allergic-type reactions to sulfonamide drugs. If someone is sensitive to sulfa, the most common reactions manifest on the skin as rashes. However, symptoms can also be more severe.

    Sulfonamides are one of the earliest developed antimicrobial drugs. They are used less frequently than in the past because safer, more effective medications have replaced them. However, they still have uses today, especially for treating certain infections, including:

    • Pneumocystis pneumonia caused by the fungus Pneumocystis jirovecii
    • Uncomplicated cystitis
    • Stenotrophomonas maltophilia infection, a bacteria that can live in IV fluids, respiratory mucus, and urine

    The most common sulfa drug associated with sulfa allergy is sulfamethoxazole-trimethoprim .

    How Are Drug Rashes Diagnosed

    Sulfa Allergy: Symptoms, Causes, Diagnosis, and Treatment

    Diagnosing a rash caused by a reaction to medicine is complicated. First, a complete review of all prescription and over-the-counter medicines should be done. Even a small amount of a medicine can cause a major reaction in the skin. In addition, the reaction can occur even after you have taken a medicine for a long time. Your healthcare provider will usually advise you to stop taking any medicine that is not needed to sustain your life, to see if the reaction eases. Your provider may give you a substitute medicine, if possible. In some cases, a skin biopsy may be done to help with the diagnosis.

    How Are Drug Rashes Treated

    Drug rashes may go away on their own once you stop taking the drug that caused your rash.

    However, the exact timeline also depends on the type of rash you have, as well as the severity. More severe drug rashes, such as erythroderma, may cause permanent changes to skin pigmentation after treatment.

    In cases where you have other symptoms, your doctor may recommend other medications for relief. For example, if the rash is very itchy, an antihistamine or oral steroid can help manage the itching until the rash clears up.

    If you suspect you have a drug rash, talk with your doctor right away. Never stop taking any prescribed drugs without discussing it with a doctor first.

    This is especially important if youre taking multiple drugs. Your doctor will have you follow a specific plan of discontinuing each drug until they can help you figure out which one is causing adverse reactions.

    Some drug rashes are severe and require emergency medical treatment. These include severe urticaria, erythroderma, SJS/TEN, anticoagulant-induced skin necrosis, and DRESS. At the hospital, you may be given intravenous steroids and hydration.

    Treating Allergies On The Skin

    For allergic reactions that cause skin symptoms, including those associated with allergens found in animal saliva, poisonous plants, drugs, chemicals and metals, additional treatment options include:

    • Topical corticosteroid creams or tablets. Corticosteroids contain steroids that reduce inflammation and itching. Mild forms of these creams can be found online, and a doctor can prescribe stronger versions.
    • Moisturizing creams. Emollient creams with soothing ingredients, such as calamine can treat skin reactions.
    • Bite or sting medication. Medication targeted to reduce allergic reactions to insect bites or stings have a similar effect to other allergy medications.
    • Ice pack. Applying an ice pack wrapped in cloth to the area for 10- to 15-minute intervals can reduce inflammation.

    Sulfa Drugs And Skin Allergic Reaction

    Antibiotics containing the SO2NH2 moiety can trigger an allergic reaction in 3 percent of patients. An allergic reaction to sulfa drugs typically develops 30 minutes to 8 hours after taking the drug and takes on the appearance of rashes involved with hives on the skin 4. In addition to rashes and hives, the individual may develop well-defined patches of swelling and redness on the skin that are sometimes surmounted by a blister.

    A severe allergic reaction can lead to anaphylaxis, resulting in a drop in blood pressure, nausea, vomiting, dizziness and loss of consciousness. In addition to anaphylaxis, life-threatening skin reactions such as Stevens-Johnson syndrome and toxic epidermal necrolysis can occur. These severe adverse skin reactions typically begin with a headache, fever, and body aches. Then skin lesions or eruptions appear on the face and trunk of the body. These lesions begin to erupt or blister, causing a separation of the outer layer of the skin from the tissue layer on the skin. Stevens-Johnson syndrome and toxic epidermal necrolysis are extremely dangerous since the skin is no longer present to act as a barrier to pathogenic organisms the individual becomes highly susceptible to different types of infections.

    Causes Of Sulfa Allergy

    A sulfa allergy takes place when your immune system identifies the drug as a dangerous substance. Thus, your body develops antibodies specific to the drug and attack against it.

    The presence of sulfonamide in certain antimicrobial drugs can give rise to negative response when an individual has a sulfa allergy.

    Such an allergic response takes place due to differences in the molecular structure between types of sulfonamides.

    Chemically, sulfonamide antibiotics are different from other sulfonamides non-antibiotics because they have an arylamine group. This arylamine group is associated with hypersensitivity and allergies.

    A cross-reactivity between arylamine sulfonamides is common and thus, its use must be avoided in individuals who are sensitive to it.
