In brief: Up to a few weeks
It can last a few weeks.
If more than this consider whether you've been exposed more than once, or if you still have intermittent exposure (ex oil from poison ivy on dog's fur can still get you). Wash all of your yardwork clothes, gloves, etc, if you have one shampoo the dog, wear long sleeves & pants when you're outside. If still a problem then see your doctor for eval of poss alt diagnosis.

Benadryl does nothing for ivy allergic dermatitis. It is not contageous It is not spread by scratching. Clobetosol helps. Get a prescription.

Yes, I agree, scratching does not spread it; it is from contact with the plant's oil. A topical steroid is the most likely to help treat. Hope you're feeling better soon.

In brief: It Could
Poison ivy reaction can last on average anywhere between 1-4 weeks depending on extent of rash and treatment.
Also, scratching it can cause it to spread and increase the time it takes to heal. Oatmeal baths and cool compresses can help soothe your symptoms. Calamine lotion and benedryl may also be helpful. Good luck.

In brief: It can
Though it is usually due to people putting topical benadryl, (diphenhydramine) either creams or liquids, and developing an adverse reaction to it.
If it has been going on for weeks, you need to be seen.
