For those with high blood pressure, phenylephrine is an alternative to pseudoephedrine. They are in the same drug class known as nasal decongestants, which help relieve sinus congestion and pressure. You can buy products containing phenylephrine right off the shelf at the pharmacy.
Which is a better decongestant phenylephrine or pseudoephedrine?
Studies have shown that pseudoephedrine is a much more effective decongestant than phenylephrine. Phenylephrine’s decongestant effects may not be significantly different from that of a placebo. The effects of both drugs may be augmented with concurrent use of other products that affect rhinitis, such as antihistamines.
What replaced pseudoephedrine?
As a result of the growing restrictions on pseudoephedrine, some companies have replaced it with phenylephrine as a nasal decongestant as this cannot be converted to methamphetamine.
Is there a better decongestant than Sudafed?
Yes. Most patients and healthcare providers will agree that Sudafed (pseudoephedrine) is more effective for congestion than its counterpart Sudafed PE (phenylephrine). This is likely due to the fact that the intestines will absorb only about 38% of the amount of Sudafed PE in one tablet, while Sudafed is 100% absorbed.
Is phenylephrine safe than pseudoephedrine?
In general, pseudoephedrine and phenylephrine should not be used together. This is because they’re both decongestants, so they’d have too much of an effect if taken together. Combining them could lead to increases in both blood pressure and heart rate.

How do I choose the best over-the-counter decongestant?
To choose the best over-the-counter decongestant for you, begin by considering your symptoms. If nasal congestion is your only complaint, a simple decongestant may fulfill your needs. Should you have additional symptoms such as watery eyes, unproductive cough, or headache, you may find that a product which treats multiple symptoms is more suitable.
How do decongestants work and their possible side effects?
Common Side Effects. Decongestants can cause sleep problems and nervousness due to overstimulation of the brain. They can also cause other side effects, such as raising blood pressure.
