- How long does Phenylephrine stay in your system if was used for a cold/alka seltzer?
- Q: Alka-seltzer Plus cold and cough/liquid gel form. This is a new formula using Phenylephrine. I consumed eight pills total; last taken over a week and a half ago. Thanks.
- A: Only 38% of an oral dose of phenylephrine is able to be used by the body. The elimination half life is 2 to 3 hours meaning that it only takes 2 to 3 hours for half of the dose taken to be eliminated from the body. If a 10mg dose of phenylephrine is taken 3.8 mg will be distributed into circulation. In 2 to 3 hours half of that will be eliminated so only 1.9mg will be left. For every 2 to 3 hours this will continue until the dose is completely removed. To sum it up, phenylephrine is not terribly effectivewhen taken orally because it is poorly available to the body and it is metabolized and removed very quickly.
- Does a decongestant or phenylephrine cause high or low blood pressure?
- Q: I know they can make you drowsy.
- A: “Decongestants work by constricting blood vessels, which in turn shrinks the swelling in the nose and open nasal passages. While this constriction of blood vessels helps alleviate congestion, it may raise high blood pressure temporarily after each dose. Some common decongestants include pseudoephedrine and phenylephrine.”The only ones that are safe to take are those specifically formulated for people who suffer from hypertension, like Coricidin HBP(R).ETA: BTW, that includes not only pills and liquids but nasal sprays.
- Why does pseudoephedrine work better for my congestion than phenylephrine?
- A: Phenylephrine is extensively metabolized by the liver and doesn’t work as well as PSE.
