If im allergic to aspirin, can i take sudafed with no worry?

Sudafed and aspirin: Technically Aspirin and sudafed/pseudoephedrine are not related. The problem is that there are many medications that carry the sudafed branded name- some of which might contain nsaids. So reading labels is imperative.

Probably: Plain over the counter sudafed should be safe in the presence of allergy to aspirin. However, be careful, many cold and allergy decongestant pills in the drug store have multiple component medicines, so it is always important to look at all of the ingredients to be sure Aspirin is not included. Your pharmacist may be able to help you as well.
