Being a stimulant, you should avoid mixing caffeine with other stimulants. It could make you jittery. Avoid mixing it with albuterol and steroids. Note that caffeine can constrict the blood vessels. Caffeine could limit the ability of the medication to flow through your bloodstream.
Benadryl and Antihistamine
The main ingredient in Benadryl is diphenhydramine, a first-generation antihistamine. It relieves watery eyes, an itchy throat, a runny nose, sneezing, and other signs of allergies.
If you have no issues with caffeine or antihistamines, you can mix them. Do it unless your doctor advises otherwise. Note that there is a slight risk of adverse effects due to the interaction of medication and coffee. But, issues relating to caffeine and Benadryl are rare.
Benadryl has a sedating effect, and caffeine is the opposite. Therefore, mixing them could negate side effects.
