Antihistamines and weight loss

tigerblue

I've just read some disturbing things about how antihistamines can inhibit weight loss or even cause weight gain. I have to take either Benadryl or Zyrtec often because of nasal allergies. This is also a professional issue since I am a musician and the nasal allergies cause laryngitis. So there are times I absolutely have to take them.

I had suspected that they perhaps caused me to retain fluids, and possibly to not eliminate well (poop), and what I am reading confirms that. But I am also reading that they increase appetitie and can slow metabolism. Wow!

What are your experiences with these drugs and others like them?

Meh. There seems to be a slight correlation from what I could pull down quickly, but that doesn't mean they actually do any of those things. The more sedating ones (old class antihistamines like Benedryl) might cause you not to burn as much through NEAT activity because they cause sedation. No big surprise there.

If you need your Zyrtec, take it. I take some most days and haven't noticed any troubles with weight gain or loss.

I take Benadryl and Zyrtek for allergies. I find they work very well (Benadryl makes me sleepy though). I don't think they make a dang bit of difference for weight loss. At least I don't notice any difference related to anything other than caloric intake vs output.

I read the same thing about antihistimines but I never noticed a difference when taking them or not and I have tried both. I suggest you don't suffer with allergies and just take them.
