Depends on Problem: If you were put on loratadine for allergies and it is not responding to the medication you can take the loratadine in the morning and Benadryl (diphenhydramine) at night. But, there are other allergy medicine that may help you more. I would suggest letting your doctor know you are not getting relief. Also, be careful with Benadryl (diphenhydramine) as it can be sedating and driving with it is a DUI in many states.
