What should patients do if they experience allergic reactions to Penicillins?

When a patient experiences an allergic reaction to penicillins, seeking emergency treatment is crucial. Allergic reactions can range from mild to severe, including anaphylaxis, which can be life-threatening. Prompt medical intervention is necessary to manage severe symptoms, such as difficulty breathing, swelling of the face or throat, rapid heartbeat, or a severe rash.

Over-the-counter antihistamines may be helpful for mild allergic reactions, but they are not sufficient in the case of a severe allergic response. Continuing to take the medication can exacerbate the reaction and lead to more serious consequences, especially if the allergy is severe. Consulting a nurse within a delayed timeframe, like 48 hours, does not provide the immediate care needed for such reactions, especially when symptoms can escalate rapidly. Therefore, the best course of action is to seek emergency treatment right away.
