How much childrens benadryl (diphenhydramine) can i give my 16 mo old? my doc and nurse said that 1 tsp is ok, the box says not to give at all. it's for a flight.

? Flight ?: The dose is generally 1 teaspoonful per 25 pounds.You may want to be sure what effect it has on your kid before you use it as a sedative.Sometimes kids will have the opposite of the expected sedation and become hyper, which would not bode well for your flight plans. Keeping the kid up late the night before and limiting their day naps can help them sleep through the flight.

Depends on weight: Dose of Benadryl (diphenhydramine) depends on the weight.It is not recommended in children less than 1 year of age.Dose for 20 to24lbs is Benadryl (diphenhydramine) is 3/4 tsf.25to37lbs is 1 tsf.The effect lasts for 4to6 hours.But it is not a good idea to give sedatives to babies for flight as benefits outweigh side effects.Benadryl (diphenhydramine) can make some children hyper and irritable.Useonly if you have used it before& there was no il effect.
