If a patient receives an injection but has an unknown allergy to the medication administered, the immediate treatment would typically involve managing any allergic reaction that may occur. The drug most commonly used for an acute allergic reaction is epinephrine, which is administered intramuscularly.
In cases of severe allergic reactions (anaphylaxis), epinephrine is the first line of treatment and is often administered via an auto-injector (e.g., EpiPen).
In addition to epinephrine, other treatments for allergic reactions may include:
- Antihistamines (like diphenhydramine) to help alleviate mild allergic reactions.
- Corticosteroids (like prednisone) may be used for more severe reactions or to reduce inflammation.
It's critical to monitor the patient closely for any signs of an allergic reaction after an injection, especially if they are known to have allergies to certain substances. Always consult a healthcare professional for specific medical advice and treatment tailored to the patient's condition.
