What is the max amount of Benadryl (diphenhydramine) I can take in a day?

Technically, 300mg : I don't recommend taking more than 100mg (25mg every 6 hours) without physician input, as that can be extremely sedating. That said, technically the dose is 25-50mg every 4-6 hours. If you take 50mg every 4 hours that makes 300 mg. ...Read more

Bad: Benadryl (diphenhydramine) can make you sleepy, but it can have after effects. Studies show that using too much of it can lessen your responses similar to drinking alcohol. It is found in many over the counter sleep medications but I do not believe that most doctors would recommened them. Would check with your doctor. ...Read more

Any age: Asthma can develop at any age. Most children who develop asthma will have symptoms before 3 years old. 20% of adult onset asthma will have an occupational trigger for their asthma.

Steroid nasal spray: I assume you mean your nose is still stuffed. Benadryl (diphenhydramine) is a short acting antihistamine that can cause drowsiness. I recommend Allegra 180 mg once a day.

Is Benadryl (diphenhydramine) perfect to take Monday-Friday to control my perfume allergy while being in highschool? Thank you. :)

Not Really: Benadryl (diphenhydramine) can make you sleepy and have an effect on your ability to pay attention and concentrate in school. In addition, perfume "allergy" is not really an allergy but what we call faso motor rhinitis or non-allergic rhinitis. The best treatment for this is a intranasal antihistamine mast cell stabilizer like azelastine or olopatadine spray. See your doctor. ...Read more
