how many mg of benadryl can you take pregnant?
When you're pregnant you can take the same dose of Benadryl as before pregnancy. For standard Benadryl, that means no more than 1 to 2 tablets every 4 to 6 hours for an adult. Some small, older studies suggested that taking Benadryl the first trimester of pregnancy could lead to a slightly higher risk of birth defects.
