See the DrugPatentWatch profile for Diphenhydramine
What trade name is diphenhydramine sold under?
Diphenhydramine is sold under multiple brand names depending on the country and the product form (oral tablets/liquid, capsules, injections, or topical/OTC allergy products). Common U.S. trade names you may see include Benadryl and Unisom SleepGels (sleep-aid products), among others.
How do I find the exact diphenhydramine brand on my package?
Check the label for the generic name diphenhydramine under “active ingredient.” The same active drug can be marketed under different trade names, and combinations (for example, with other antihistamines or pain relievers) can change the brand and ingredient list.
Does the trade name change by formulation?
Yes. For example, oral allergy products and sleep aids can use different brand names even though the active ingredient is diphenhydramine. Form also matters for labeling and dosing instructions.
Can you name the trade name if I tell you the country and product form?
If you share (1) your country, (2) whether it’s tablets/capsules/liquid/injection, and (3) what the package says besides diphenhydramine, I can narrow it to the most likely trade name(s).
