My asthma seems aggravated by my post nasal drip. can't seem to clear my throat entirely. bad allergies, chronic sinusitis. will sudafed help?

May: If you do not have hypertension you can take sudafed safely for post nasal drip.

Short term only: Sudafed is not a good long term answer to your problems. After using it for a few days when you may really notice a big difference, you can actually then develop rebound increase in mucous production and would have to take more and more to get relief. Not a good thing. Have you discussed intranasal steroid treatment with your doc or ent. Also daily rinses of your sinuses with a neti pot may help!

That and others: Sudafed can help but try not to use it for a prolonged time. There are anti-allergy meds that can help also. I find nasal saline irrigation to helps me and my patients. It seems weird at first, but hang in there, it is actually quite good at relieving nose related symptoms.
