My body feels itchy. I had this during my pregnancy. Took allerid n felt better. But the itch has started again...Its from head to toe. What to do?

Antihistamine 4 itch. Antihistamines are usually the most helpful medications you can take for itching. You can get benadryl, (diphenhydramine) zyrtec, allegra, Claritin and other ah otc now. Any of these may help itching, but Claritin might be the least effective; results are individual. If the itching continues or worsens over time, see an allergist for help figuring out why you are itching. It could be a disease that needs attention.
