A specific drug that a lot of people claim to be allergic to is penicillin. However, we should clarify that not all people who report being allergic to this drug experience true allergic reactions.
If you experience common adverse drug reactions to penicillin, you are likely to develop symptoms like headache, nausea, diarrhea, and vaginal itching.
Sulfa drugs are also antibiotics. However, they contain substances called sulfonamides. The interesting thing about sulfa drugs is that the person may not be necessarily allergic to the sulfonamides group or sulfur in general. They are just allergic to the sulfa antibiotic drugs.
For instance, there are medications for diabetes and arthritis that contain sulfonamides and people do not necessarily need to avoid them just because they are allergic to sulfa antibiotics.
Still, Sulfa drugs cause common adverse drug reactions like nausea and vomiting, headache, dizziness, diarrhea, and lethargy.
NSAIDs or non-steroidal anti-inflammatory drugs are primarily used to reduce pain or fever. Common examples of NSAIDs are ibuprofen, mefenamic acid, aspirin, and naproxen. They are quite notorious for some common adverse drug reactions ranging from headaches and dizziness to stomach pain and ulcers.
As you will notice, many NSAIDs are over-the-counter medications, allowing people to have access to them even without a physician’s prescription. Despite being safe for most people, itis still possible for others to develop some allergic reactions to NSAIDs.
Insulin is a common drug given to diabetic patients as it helps control their blood sugar levels. However, it can cause allergic reactions, especially if it is animal-derived. If you are allergic to insulin, you may experience localized or systemic symptoms. When we say localized, it only affects certain parts of the body. When it is systemic, it affects the entire body.
Once again, you can develop adverse reactions even if your immune system is not involved. In those times, you are not experiencing allergic reactions.
Signs and Symptoms of Drug Allergy
If you have an allergy to certain medications, you may experience the symptoms within an hour after taking the drug. At times, you may experience them after a few hours, days, or even weeks later.
