Possibly: Benadryl (diphenhydramine) is a sedating antihistamine. The best answer i can give you is if the mucus production is caused by an allergic rhinitis (allergy of the nose) Benadryl (diphenhydramine) will help. However, if the mucus production is not of an allergic etiology, the antihistamines will be of little help and an otc decongestant will be more helpful for symptomatic relief.
