Over-the-counter antihistamines are safe to take if you use Lexapro. But I suggest you use one that does not cause drowsiness. Antihistamines can cause drowsiness, which can be more pronounced in someone taking a medication like Lexapro. Always ask your pharmacist before using an over-the-counter medication to ensure it is safe for you.
