If you have a reaction after taking a medication, chances are it’s a side effect, not an allergic reaction. Side effects occur when the medication causes a problem, such as nausea, sun sensitivity, or liver damage.
Allergies account for 5-10% of all drug reactions. If you have an allergy, your symptoms don’t come from the drug; they occur when your immune system reacts to the medicine and releases chemicals that cause allergy symptoms.
Any medication may cause an allergy, but the most common include:
If you’re allergic to one drug, you have a higher risk of developing an allergy to other medications.
Drug allergy symptoms may occur in hours to weeks after taking the medication. Though not as common, some medications cause a skin rash that doesn’t appear until six weeks after you take the drug.
When your symptoms appear, you may have:
Drug allergies can also cause a life-threatening anaphylactic reaction. This serious allergic response occurs quickly, causing symptoms such as:
Anaphylaxis is an emergency that requires immediate attention. If you have an epinephrine pen, use it right away and call 911.
Allergy and Asthma Institute, LLC, specializes in customized allergy care, beginning with allergy testing to identify the medication. After verifying the drug that is causing your allergic reaction, your provider may prescribe antihistamines to improve your symptoms or steroids to reduce inflammation.
However, the main treatment for a drug allergy is to stop taking the medication. If you need the drug for a health condition, your provider may recommend drug desensitization.
Desensitization occurs in the office under close supervision. During the treatment, your provider gives you doses of the drug every 15-30 minutes. You start with a very small dose, then each one gets a little larger. Your treatment continues, gradually desensitizing your immune system.
The process continues until you have an allergic reaction or reach the full dose. If you can get to the full dose without having an allergic reaction, you can take the medication as needed.
Drug allergies can cause serious reactions, so don’t wait to seek help. Call Allergy and Asthma Institute, LLC, or book online today.
