Pseudoephedrine is the original decongestant in Sudafed. It’s a sympathetic nervous system stimulant that induces “fight or flight” response, which raises your heart rate and blood pressure. Part of the effect is to constrict blood vessels, which is how it works as a decongestant. Constricting the capillaries in your sinuses and nasal passages reduces the swelling, which opens up the breathing passages.
That is what the doctor said to give the kids when they got it, worked great, I tried it to and was amazed how it cleared out my lungs.
They got natural immunity now. They won't need it.
I can’t take Sudafed- there’s something in it that makes my heart race real bad. Not sure if that’s a common side effect?
Yes, that's why if you have high blood pressure you can't take any of the effective decongestants.
Hmm. I’ve always had good blood pressure.
