Because there are so many antihistamine products, both over-the-counter and prescription, and because they are used to treat so many different conditions, you may need help figuring out which medication to take. For minor ailments, you can probably take over-the-counter products. You can read the package labeling and match your symptoms to the labeled symptoms. Also, never hesitate to ask the pharmacist.

They will also want to know if you are pregnant, plan to become pregnant or are breastfeeding. Some antihistamines are not recommended in pregnancy because they may cause birth defects in very high doses. Antihistamines can pass into breast milk, so you should consult with your healthcare provider before using antihistamines if you are breastfeeding.

In addition, some individuals can be ‘slow-metabolizers’ or ‘fast-metabolizers’ of Benadryl, which alters how long the effects last for.

Benadryl is typically dosed at 25 to 50 mg at 4 to 6 hour intervals.


Zyrtec has a duration of action of 24 hours, which is the claim to fame of most ‘second-generation’ antihistamines. This long duration of action allows it to be dosed only once a day, which is ideal for treating perennial and seasonal allergy symptoms.

The most common dose of Zyrtec is 10 mg once daily, although low doses of Zyrtec twice daily can be used in young children for certain indications, like atopic dermatitis .

Antihistamines are often combined with decongestants and/or pain relievers. If you take a combination medicine, its important to know each active ingredient. One or more could interact with other medicines youre taking.
