Is there an over-the-counter antihistamine medication available to treat poison oak?

Steroids needed. If you have a significant case of poison oak, antihistamines are unlikely to faze the itching. You probably need oral steroids. You can certainly try oral antihistamines and topical steroids like cortisone 10, but these rarely control the severe itch of even a moderate case. Better see your doctor for stronger stuff. Most cases last about 3 weeks.
Many. Many otc antihistamines can treat the itching associated with poison oak. These include claritin, (loratadine) clarinex, zyrtec and allegra. Older antihistamines are available but associated with drowsiness, delayed reaction time and dry mouth. Treatment with topical cortisone treatment is usually necessary for poison oak and sometimes requires higher potency than is available over the counter.

I got poison oak and was given hydroxyzine as an antihistamine, but it makes me really drowsy. Is there anything I can do to counteract this effect?

Non drowsy antihist. Instead of using hydroxyzine, you may be better off using a 'non-sedating' antihistamine such as Allegra (fexofenadine) or Zyrtec (cetirizine) which are effective for itchiness but do not cause the sleepiness you are experiencing. Both of these medications work for 24 hours (not 6 hours like hydroxyzine) which is also a benefit. You can also apply hydrocotisone cream to the itchy areas. Read more...
