Question

What is the strongest antihistamine?

Answer 1

The strongest antihistamine that you can get over the counter is Brompheniramine (Dimetane).

However if you want an even stronger antihistamine then you would have to have your doctor prescribe a by prescription only antihistamine.

But usually the Brompheniramine (Dimetane) over the counter antihistamine will work just as great as the prescription antihistamine.

Zyrtec and Allegra are also other good strong antihistamines that work great for allergies.

Answer 2

Thank you for the thread! I would also like to add that you can buy such medicine for you from Canadian Pharmacy Online, for example. I have been using that service for some time, and I am really happy with it. Good luck, guys :)

Answer 3

I would highly recommend taking Zyrtec for a good strong antihistamine that you can get over the counter.

I've used and still use Zyrtec for my allergies and although it can be a bit more expensive than other allergy medicines the Zyrtec is well worth the money and has always worked well for my allergies.
