### Human:\nis there a safe dosage of benadryl i can give my 5-month-old baby who is battling a very congested nose?\n\n### Assistant: benadryl is not a nasal decongestant and will do nothing for the stuffy nose (not to mention this medication should not be given to a child this young. ) you want to use saline drops to help thin out the mucus in the nose and then use a nasal aspirator to help clear the passageway. i also recommend running a vaporizer in the baby's bedroom -- that usually helps a lot as well for congestion. parents need to be very careful about cough and cold medications in infants and children so take the time to talk to your pharmacist.
