Question: how much benadryl can you take while pregnant third trimester?
Answer: Your obstetrician may suggest Benadryl if you are pregnant and suffering from allergies, hayfever, nausea, vomiting, or lack of sleep. 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.
