Question 1

When is the best time to take an antihistamines for an allergy? why?

Accepted Answer

It depends on the antihistamine and when you are exposed to the cause for your allergies.  Antihistamine pills generally take at least 30 minutes to two hours to take effect and peak hours later.  Pollen levels are highest in the morning, but if you are exposed to other allergens such as animal dander or dust, those levels would affect you at night.  Take it a few hours before your worst time.

Question 2

I seem to have developed an allergy to our new dogs.  tried several antihistamines but benadryl (diphenhydramine) works best. can i take on a regular basis?

Accepted Answer

Remember the best treatment is avoidance and we have the same problem. I'd sacrifice to be with my dogs too, hehehe. If you can tolerate Benadryl (diphenhydramine) and it's the only thing that works, you can take it regularly, but remember, it can make you sleepy.  Have fun with the dogs, i hope you will develop tolerance.

You can take either an antihistamine or H2 blocker  (or both immediately following using an epipen (epinephrine).    It may help stop a worsening allergic reaction.   Anti histamines block H1receptors  and H2 blockers work on H2 receptors so you are blocking both histaminic receptors.   Best is to avoid whatever you are sensitive too in the first place.
