Can i take loratadine tablets 10 mg with Unisom sleeping aid sleep gels?

Unisom Sleep Gels (diphenhydramine) use a short acting antihistamine to make one drowsy and easier to fall asleep. The loratadine (Claritin) is a long acting antihistamine that is promoted as being "non-drowsy", who's main side effects are drowsiness and fatigue. 

So, as you can tell, an interaction is possible, these drugs are often used together. You may feel drowsy or more tired when taking these drugs together. Do not drive or operate machinery until you know how these drugs affect you.
