Topamax and Allergy medications

Hello! I am currently taking Topamax (I was taking 50mg, now I'm taking 25mg) for my migraines and I have had one doctor and one pharmacist tell me that I should not take allergy medications with Topamax because there would be adverse side effects. Is this true and if it is, is there something I can do for my allergies?

I'd think your Dr would help you alittle more. By the way,
in June, FDA gave ok to a generic Topamax you should be asking
abt to save some $. As far as a allergy med, many are sedating
& would also help migraines but so is Topamax to some. Zyrtec is
a 1 a day time release rx w/ little affects w/ other rx's. It
isn't sedating yet they all say 'may cause'. Unless you have
severe blood pressure problem & on meds for that. Ask Dr abt
some samples of Zyrtec. Most ENT's have them or I think there's
a online sample request if Dr signs a script to release. Not
sure how it works but ask Dr & ck out Zyrtec's site by google?
Your allergies may be causing you more hdaches. I've taken
many types of pain meds w/ Zyrtec w/ no problems. Keep in mind,
this isn't always affective rx for everyone & it's a trial by
sneeze or whatever you have. Gd-luck

I take topamax 100 mg, Zyrtec 10 mg,Trileptal 600mg, plus Benedryl everynight and I am still alive. All of my medicine says "may cause"  but I never get sleepy.  I am one of those types of people that could stay up for days!
