From the Guidelines
Benadryl (diphenhydramine) can be used at 9 weeks gestation, but with caution, due to some concerns over a potential association with cleft palate, although recent studies have not detected any increased risk for congenital malformations 1. When considering the use of Benadryl during pregnancy, it's essential to weigh the benefits against the potential risks. The first trimester is a critical period for organogenesis, and medication use during this time should be approached with caution 1. Some key points to consider when using Benadryl during pregnancy include:
- The typical recommended dose is 25-50 mg every 4-6 hours as needed, not exceeding 300 mg in 24 hours.
- Benadryl is classified as FDA Pregnancy Category B, meaning animal studies have not shown risk to the fetus, and there are no adequate studies in pregnant women showing adverse effects.
- While no significant birth defects or problems have been consistently linked to Benadryl use during pregnancy, it's always best to use the lowest effective dose for the shortest time necessary to manage your symptoms.
- Some women may experience increased drowsiness or dry mouth when taking Benadryl during pregnancy. It's crucial to consult with your healthcare provider before taking Benadryl, especially during early pregnancy, as they may recommend alternative treatments that are better studied or more appropriate for your specific situation 1.
