Which medications to stop before allergy testing?

Before allergy testing, it is generally recommended to stop antihistamines, including over-the-counter options like diphenhydramine and loratadine, at least 48 hours prior to testing, as they can interfere with results. Additionally, certain medications such as corticosteroids may also need to be paused, depending on the type of allergy test being performed. Always consult with your healthcare provider for personalized advice on which medications to discontinue before testing.
