Reactions to medications can often be confused with side effects or intolerances. Drug allergies are unique in that they involve the immune system mistakenly identifying a medication as harmful. Here is more information on this type of allergy, the medications that may be involved, symptoms to look out for, and available options for addressing them:
What Are Drug Allergies?
A drug allergy occurs when the immune system reacts to a medication as though it is a harmful invader. This triggers the release of histamines and other chemicals, leading to an immune response. The reaction is typically caused by the body’s prior exposure to the drug, wherein the immune system has become sensitized to it.
Drug allergies should not be confused with drug side effects or drug intolerances. Side effects are unintended effects of a medication, while intolerances, such as stomach upset from antibiotics, do not involve the immune system. Consulting a specialist helps with the diagnosis and treatment of this condition.
What Medications Could You Be Allergic To?
Drug allergies can be triggered by a variety of medications. Antibiotics, such as penicillin and sulfa drugs, are common culprits. Nonsteroidal anti-inflammatory drugs (NSAIDs), like ibuprofen and aspirin, may also lead to allergic reactions in some individuals.
Chemotherapy agents and medications used to treat autoimmune diseases have been associated with allergic responses. Even over-the-counter drugs, including certain pain relievers and cold medications, can cause allergic reactions in sensitive individuals. It is helpful to be aware of the symptoms of this kind of allergy so that you can know if you are having an adverse reaction.
What Are the Symptoms of a Drug Allergy?
Drug allergy symptoms can vary widely, from mild to severe. Common symptoms include skin rashes, hives, and itching. More severe reactions may involve difficulty breathing, swelling of the face or throat, and wheezing.
Anaphylaxis, a life-threatening reaction, is a possibility with drug allergies. It may present as a combination of symptoms, including rapid heartbeat, low blood pressure, and confusion. If left untreated, anaphylaxis can progress quickly, requiring immediate medical intervention.
What Can You Do About Drug Allergies?
The first step when a drug allergy is suspected is to consult a healthcare professional. A doctor may recommend stopping the medication and substituting it with an alternative. Discontinuing the drug should always be performed under medical supervision, particularly for certain medications.
For mild symptoms, antihistamines may be used to block histamine production and provide relief from itching and hives. Corticosteroids, either oral or topical, may help reduce inflammation and immune response. If symptoms progress to anaphylaxis, emergency treatment is required. Epinephrine is typically administered to counteract severe allergic reactions.
Desensitization may be recommended for those who need to take a specific drug despite their allergy. This involves gradually introducing small doses of the drug under strict medical supervision. This allows the immune system to tolerate it over time.
