Is there a difference between Benadryl (diphenhydramine) and pseudoephedrine?

Benadryl (diphenhydramine) and Sudafed. Benadryl (diphenhydramine) is an antihistamine (blocks the histamine receptor) and sudafed is a decongestant. Basically sudafed grabs a hold of the blood vessels and squeezes them down for a period of time. Hence the reason that rebound congestion and high blood pressure are attributed to this medicine.

Can you give a child Benadryl (diphenhydramine) and sudafed at the same time?

Avoid decongestants. Pseudoephedrine (sudafed) can cause irritability and high blood pressure in children but doesn't seem to actually help with congestion until puberty. Sudafed-pe (phenylephrine) has the same issues but typically is very poorly absorbed into the body. These drugs should never be given to children given the potential harm and lack of benefit. Benadryl should be limited to once a day during a cold. Read more...
