Warning Signs of Allergy to Medication
Always report any unpleasant or unexpected side effects of medication to your doctor.
The following symptoms may indicate an allergy to medication:
• rash
• hives (itchy, raised, red patches on the skin)
• itching
• swollen lips
If you experience any of these symptoms after taking medication, contact your doctor. If you experience more serious symptoms—such as nausea and vomiting, difficulty breathing, confusion, loss of consciousness, swollen tongue or throat, or slurred speech—seek emergency medical help immediately. A severe allergic reaction is a medical emergency that can lead to respiratory failure and shock (see “Anaphylactic Shock,” Post).
