In a similar vein the correct type and dose of vitamin E will prevent and reverse cardiovascular disease and it can help lung disease by allowing more oxygen to cross in to the blood from the lungs, and it can prevent hair loss with chemotherapy.
In a more balanced and fair presentation this popped up on my screen today –
The M.D.: So what’s the risk of taking that medication?
What to consider when reading drug companies’ mandated lists of side effects, which can be hard to understand or overwhelming.
Invariably, they’re intrigued. It works by preventing testosterone from turning into another hormone that causes hair loss. Over five years, the majority of men who take the drug report that their hair loss slows, their bald spot gets smaller and the appearance of their hair improves. However, the threat of drug-related side effects such as impotence, male breast cancer and perhaps prostate cancer has caused many of my friends to seriously reconsider the importance of a full head of hair.
This scenario is hardly unique to Propecia. Every medication on the market offers potential benefits and also carries risks. Deciding whether to take a drug requires a close evaluation of both. Unfortunately, the information necessary to make that decision isn’t always readily available, particularly when it comes to side effects.
Although manufacturers are required to inform consumers about side effects, these disclosures are often made in a way that render them incomprehensible and largely meaningless. On television commercials, for example, side effects are usually rattled off in quick succession toward the end of an ad. Potentially life-threatening problems such as liver failure, blood clots and stroke are presented alongside comparatively innocuous ones like nausea, dry mouth and constipation. And the likelihood that any of them will actually occur is ambiguous.
The U.S. Food and Drug Administration tries to ensure that pharmaceutical companies present the pros and cons of their products in a way that’s accurate and balanced, says Thomas Abrams, director of the FDA’s Office of Prescription Drug Promotion.
“We want people to get good information so that they can make good decisions,” Abrams says. “But that’s not an easy thing sometimes, given the complexity and technical nature of prescription drugs.”
Drug companies tend to do a better job with print advertisements — in large part because the FDA requires it. Print ads must contain a “brief summary” that includes a list of all possible side effects. When an ad is intended for consumers (as opposed to physicians), the FDA encourages drug companies to use language that’s easy to understand.
Package inserts serve as the most complete source of information about medications. These inserts include just about everything that’s known about a drug — from how it works to how to treat an overdose — and the FDA requires that consumers receive one each time they fill a prescription.
But just as too little information can leave people guessing, too much information can be overwhelming. For the average consumer, package inserts frequently add to the confusion.
Propecia’s package insert is a good example. It describes the results of several clinical trials, including the fact that 1.2 % of men discontinued taking the drug because of sexual side effects such as decreased libido and erectile dysfunction. That’s an important piece of information for potential users. But it’s also important for them to read on and see that in those same studies, nearly 1% of the men who took the placebo experienced sexual side effects and stopped treatment too.
Statistical information provided in package inserts isn’t only difficult to understand, it’s often frightening. People tend to pay more attention and give more weight to negative information than they do to positive information. And when it comes to medications even the tiniest increased risk of cancer is enough to scare away some potential users.
The FDA is aware of the need to improve the way drug information is presented to the public and has its experts on the case. Last month, researchers at the agency published the results of three studies in the journal Medical Decision Making that tested various ways of conveying information in print ads. It turned out that the format currently being used wasn’t the most effective. Instead, consumers were better able to recall information on a drug’s risks when it was displayed in a format that resembles the “Drug Facts” box on over-the-counter medications. What’s more, consumers liked this format better.
“We want people to understand, comprehend and retain the information they’re given,” Abrams says.
Hair loss treatment isn’t a matter of life and death. For men who take a pass, the worst possible outcome is baldness. Things can get complicated — and decisions more difficult — when more serious medical conditions are being addressed. If the need for treatment is urgent, a drug’s risks may be easy to accept. But if the benefits of treatment aren’t so clear-cut, the need for complete and accurate information about a drug’s risks is even more important.
My friends have put serious thought into the decision about whether to start taking Propecia. One of them was extremely concerned about the drug’s sexual side effects but opted to give it a try. Months later, his hair has regrown and his sex life is intact. Another friend is still struggling with what to do. He’s most worried about the possibility of cancer. For him, a full head of hair just doesn’t seem worth it.
I understand where both are coming from. But I have to admit, if there were a drug that could make wrinkles disappear, the side effects would have to be pretty severe to stop me from taking it.
