Depends what antihistamine you take, and what the under lying condition is as to why you are taking it. But, hell, don't ask us, ask, at the very least, your pharmacist, or even a real doctor.

I have found that anti-histamins definately causes my heart rate to be higher. I have found that I have to stay away from it for about 8 - 10 hours before a race or really hard training session other wise my heart rate goes crazy.

wow, I didnt know that allergies can cause burning lungs

 

Nah, see my post about an increased heart rate being beneficial. Thought maybe he'd got advice on how to solve the burning lungs problem.

No not related. Its just you wake up before your ride and then you have hay fever and runny nose etc. But I have the suspicion that your HR runs higher and more irregular. And I'm sure there is a 'real dr' on the Hub :-)

On the flip side mild allergic reactions can cause an increased heart rate. Taking glucosamine and chondroitin supplements for joints can cause elevate heart rate if you are allergic to shellfish. I'm allergic to lots off stuff so I live on anti histamines but I would not blame them on my dismal performances on the bike ;)

Does taking a non-drowsy anti-histamin before training/race negatively affect your performance? (like heart rate)

 

You get 3 generations of antihistamines and only 3rd generation are non-drowsy. 3rd gen are the only ones prescribed for chronic medication (I'm on them) and they have zero side effect. The only difference between my chronic and non-chronic pills is that chronic is slow releasing and lasts 16-20hrs where normal is 8-12hrs.

 

A good one is Fexaway120 (Fexaway180 is chronic).

 

Been on it for 4yrs now and first thing I buy at month end. I've got a rather tough commute in the morning and keep in my HR in 90% zone for 70% of the commute and not taking my medication reduces my performances.

 

Also antihistamines on their own are not 100% effective if your got preventative asthma like me, I need to still take a preventer each morning.

Actually thats asthma, and I suffer from this problem when the pollen count is very high especially near your misses work for some reason.

Zyrtec is good. I am on the generic - Texa

 

Interesting that even though Zyrtec is a 2nd gen AH, it was the highest-grossing non food product in the states in 2008 after it was available over the counter. Use to be prescription.

 

But I would add that if your using antihistamines for more than 2 continues weeks then see your local doctor about a chronic prescription and allergy tests. Just because one AH works for me, it may not be the one you need.
