So this itching problem started 3 years ago for me. It happens during the summer and lasts about 2-3 months. It resurfaces about every 3 years. I don’t know if what I have is cholinergic urticaria, but it sounds like it. Basically my skin feels prickly and itchy whenever I’m out in sunlight, when I’m stressed, body temperature goes up, etc. As I’ve said this only lasts about 2-3 months during the summer.
It definitely is annoying, and I’ve read that the most suggested cure is antihistamines. I’ve tried Claritin and Zyrtec in the past. They would help a little bit, but I would still feel the itch throughout the day. Lately I’ve been trying Benadryl, and I must say it does seem to be working. The trick is I need to be taking it often in order to get daily relief. For example when I started taking Benadryl, I would take 25-50mg in the morning and that’s it. This is not enough. The max daily dose of Benadryl a person can take is 300mg. So I started taking more, about 50mg every 4-6 hours as needed.
I’ve noticed that my body would get excessively itchy shortly after I would take the Benadryl, and then the itch would subside after that. I think the Benadryl is having an effect. The itch definitely seems more controlled compared to me not taking the pills
For anyone who wants to try this, I recommend talking to your doctor about taking 50mg every 6 hours. Do not take more than 50mg at once. You can also do every 4 hours which would equal 300mg for the whole day (max daily dose), if your doctor approves of this dosage.
Benadryl can make you drowsy, so be aware of that. If you feel uncoordinated I wouldn’t drive or operate machinery/devices.
I would talk to your doctor about trying the Benadryl for about a week and see how it works for you. You may only need to use it for a few months until your itch is gone if your case is like mine. My itch is seasonal and happens every few years so the Benadryl can help you get through those periods of time
My case is different in that I don’t get any rashes or visible hives on my skin. My skin looks fine, but I feel that annoying and painful itch which is the problem
Good luck all,
