Why you should stop wasting your money on cold medicine – the washington post gasco abu dhabi

A study published in the Journal of Allergy and Clinical Immunology: In Practice in September examined phenylephrine, the decongestant that appears in many over-the-counter cold medicines found 76 gas station locations on store shelves, from Tylenol Sinus to Sudafed PE to Advil Sinus Congestion Pain. Phenylephrine worked no better than a placebo at reducing nasal congestion in people suffering from seasonal allergies — even at doses four times higher than is typical in cold or sinus medicines.

One study electricity trading jobs showed that the majority of the drug is broken down in the gut and the liver, flushed 9gag memes out of a person’s system before it makes it into the bloodstream. A 2009 study that will sound especially sinister to anyone who suffers from allergies put 39 patients with a grass allergy into a sealed gas constant for air room called the Vienna Challenge Chamber. Then, the scientists piped in grass pollen. The people were given phenylephrine, a sugar pill or another decongestant called pseudoephedrine. Phenylephrine did no better than the placebo, while pseudoephedrine gas house edwards — which must be obtained by going to the pharmacist’s counter — beat them both.

Evidence of phenylephrine’s effectiveness comes from a review that combined and analyzed the results of seven individual studies. It found the drug had a small but real effect on nasal airway resistance, a technical measure of airflow in the nose, in 113 people. One to three hours after taking the gas tax by state drug, people experienced at least a 20 percent gas lighting urban dictionary reduction in nasal airway resistance.

The new study examined the drug in more than 500 people with seasonal allergies, at escalating doses. That meant it would have increased the amount of the drug that bypassed the gut npower electricity bill and liver and made it into the bloodstream. Even then, phenylephrine worked only as well as a placebo. The study used a measure of how patients felt — a nasal congestion symptom score — instead of measuring nasal airway flow.

Hendeles is drafting his second citizen’s petition to the Food and Drug Administration to have phenylephrine reviewed. He argues that companies simply a gas has don’t want to have to cut into their sales by putting their drugs behind a pharmacy counter, which is required by law for pseudoephedrine. That’s because pseudopehedrine can be used to make methamphetamine, and the Combat Methamphetamine Epidemic Act that was signed electricity kwh usage calculator into law in 2006 made it harder to obtain.

Rather than have their products vanish from store shelves, companies began reformulating medications that previously contained pseudoephedrine electricity physics formulas with phenylephrine, Hendeles said. Otherwise, people who didn’t know or want to bother to go to a pharmacy counter, people looking for sinus relief in a gas station or airport kiosk that isn gas gangrene’t a regulated seller, and people who simply don’t read ingredients and trust the words cold relief would no longer buy their products.

While pseudoephedrine has more evidence to support its use than phenylephrine, Wanda Filer, president of the American Academy of Family electricity 101 presentation Physicians, said she tends to recommend patients skip all decongestants. None of the drugs work very well, and a gas is a form of matter that they can come with side effects such as jitteriness, dry mouth and elevated blood pressure. Instead, she recommends taking a hot shower or filling a sink with hot water, draping a towel over your head and breathing in the steam.
