Cause: Drug allergies occur when the immune system reacts to medications. Penicillin (PCN) is a well-known allergenic drug.
Symptoms: Symptoms of drug allergies can range from mild rashes and itching to severe anaphylactic reactions, depending on the drug and individual sensitivity.
Treatments: The primary treatment for drug allergies is avoiding the allergenic drug, and healthcare providers will prescribe alternative medications when needed.
Prevention: Patients should always inform their healthcare providers of any known drug allergies, and these allergies should be documented in medical records to prevent future exposure. Education and awareness about drug allergies are essential to prevent adverse reactions.
