can i take benadryl while pregnant

Benadryl (diphenhydramine) is generally considered safe to take during pregnancy when used as directed. It is classified as a pregnancy category B medication, which means animal studies have not shown harm to the fetus, and evidence in humans also indicates low risk. It can be used throughout pregnancy, including the first trimester, but it is advised to use the lowest effective dose for the shortest duration possible. Benadryl crosses the placenta, so it may cause drowsiness in both the mother and the baby. In the third trimester, caution is recommended because frequent use or high doses near delivery might cause drowsiness in the newborn. Other over-the-counter antihistamines like chlorpheniramine and hydroxyzine are also considered safe alternatives in pregnancy. Nevertheless, it is important to consult a healthcare provider before starting Benadryl or any new medication during pregnancy to ensure it is appropriate for individual circumstances. In summary, taking Benadryl occasionally during pregnancy for allergy relief is generally safe, but medical advice should be sought for prolonged or high-dose use, especially later in pregnancy.
