Adverse reactions to medications are common, yet everyone responds differently. One person may develop a rash or other reactions when taking a certain medication, while another person on the same drug may have no adverse reaction at all.
Drug allergies occur when the immune system mistakenly identifies a drug as a harmful substance, triggering an allergic reaction. This article provides essential information about drug allergies, including symptoms, common triggers, diagnosis, and treatment options.
Common Drug Allergy Symptoms
Drug allergy symptoms can vary from mild to severe and may include:
- Skin Reactions, such a rashes, hives, itching, or redness.
- Respiratory Problems, like wheezing, coughing, difficulty breathing, or nasal congestion.
- Swelling and Angioedema can occur, especially around the eyes, lips, and face.
- Gastrointestinal Issues, including nausea, vomiting, abdominal pain, and diarrhea, can result from an allergic reaction to medication.
- Anaphylaxis is a dangerous and life-threatening reaction that requires immediate medical attention.
Which Drugs Typically Cause Allergic Reactions?
Certain medications are more likely to produce allergic reactions than others. The most common of these include:
- Antibiotics, such as penicillin.
- Aspirin and non-steroidal anti-inflammatory medications, such as ibuprofen.
- Anticonvulsants.
- Monoclonal antibody therapy.
- Chemotherapy.
The chances of developing an allergy are higher if the medication in question is taken frequently, is applied by rubbing on the skin, or is administered via injection.
How Are Drug Allergies Diagnosed?
After learning about your symptoms and general medical history, an allergist can diagnose drug allergies via several different diagnostic methods, such as skin prick tests or Drug Challenges, in which patients are carefully given small doses of medication to test for allergic reactions.
Treatment for Drug Allergies
The best treatment for drug allergies is avoidance. However, when avoidance is not possible, your doctor can try prescribing an alternative medication. If the medication is essential and no alternative is available, your allergist may recommend a desensitization procedure, which involves taking slowly increasing doses of the drug until your system gets used to it.
Additionally, you may also be prescribed antihistamines, corticosteroids, or epinephrine, depending on the situation or severity of the reaction.
When You Should Call a Doctor
If you suspect you have a drug allergy, you should make an appointment to consult with an allergist, especially if you experience new or worsening symptoms after starting a specific medication.
However, if your symptoms are severe (such as respiratory issues or signs of anaphylaxis), don’t wait for an appointment; go immediately to the nearest emergency room for treatment. Serious reactions can be fatal without proper medical attention.
