Many medications on the market today are prescribed for one condition but have been found to help others as well. Is your drug doing double duty?
"Many drugs do have added benefits," says Marc Siegel, MD, clinical associate professor at New York University School of Medicine. Aspirin, for example, can not only treat headaches, but it also reduces the risk of heart attack and has been shown to possibly lower the risk of breast and colon cancer, to name just a few of its benefits.
I had my first real epileptic seizure when I was 5 years old. My mother says my eyes were rolling and I was staring off into the distance. She was terrified.
What I had is called a "petit mal" seizure or an "absence" seizure. It’s called that because there’s a lapse in conscious activity for a couple of seconds. It’s different from a "grand mal" seizure, when people have convulsions. That’s what most people think of when they think of epilepsy. A petit mal seizure may not sound like much, but it’s...
Sometimes a drug is studied for one purpose and is then found to have another effect. Siegel says researchers investigating Viagra as a heart medication, for example, found that it caused erections; as a result, it became a best-selling treatment for erectile dysfunction. It has also been found to be an effective therapy for altitude sickness and can reverse the libido-lowering effect of antidepressants in women, Siegel says.
Beta-blockers are another multipurpose class of drugs, Siegel says. They not only lower blood pressure, but they can also be used to treat the pain of angina, slow heart rate and prevent disturbances in heart rhythm, prevent migraines, and stave off panic attacks and stage fright by preventing a surge in adrenaline.
Antianxiety medications such as Valium and Xanax can also be used as muscle relaxants, Siegel says.
Prescribing a medication for a condition other than that for which the drug has received FDA approval is a common occurrence, says Siegel, and is called prescribing "off label." "FDA guidelines are helpful, but they're not an all-or-nothing ruling. As long as the drug is on the market, it's OK for the doctor to use his judgment when prescribing it."
What is not OK, he says, is for patients to start medicating themselves. Just because you've read, for example, that antidepressants can ease hot flashes does not mean that it's all right to borrow a handful of someone else's pills.
"Never take anyone else's medicine," Siegel cautions. "These are prescription drugs and they're by prescription for a reason. Always call your doctor and ask for his or her recommendation for your individual condition."
