If i am having an allergic reaction to peanuts what can i take in the meantime until i go to the doc?

Benadryl (diphenhydramine) and Zantac: If you are having an allergic reaction to peanuts.. You need to be in the er (period). Peanuts are highly allogenic and a reaction could be fatal. Treatment in the er would include steroids, benadryl, (diphenhydramine) Zantac and possibly epinephrine.

Epi pen: Usually it depends on what kind of allergy you have, if you had anaphylaxis which involves breathing trouble, wheezing or throat swelling you have to inject yourself with Epinephrine , which comes as an Epipen (can be prescribed by your doctor). If it's some thing like a rash you can take some antihistamine like Benadryl (diphenhydramine) but still i would advice you to go to the nearest emergency room afterwards.

Epi, antihistamines: If there is a history of anaphylaxis (facial or throat swelling, or collapse within an hr or 2 after ingestion) immediate medical attention is lifesaving. Whole body itching is often the first symptom. Antihistamines (eg, benadryl) and Epinephrine (epi-pen or even inhaled primatene mist) can help on way to hospital. Delay can be deadly. Rash onset more than 2 hrs after nuts much less serious.

Benadryl (diphenhydramine): Due to the question you are obviously not having an emergency. If you are having breathing difficulties call 911. Otherwise avoid all peanut containing products. Benadryl (diphenhydramine) 1-2 caps every 6 hours will help until you can get to the doctor.
