Sexual Health
Drugs for treating ED can be taken orally, injected directly into the penis, or inserted into the urethra at the tip of the penis. In March 1998, the Food and Drug Administration (FDA) approved Viagra, the first pill to treat ED. In August 2003, the FDA gave approval to a second oral medicine, vardenafil hydrochloride (Levitra). Additional oral medicines are being tested for safety and effectiveness.
Erectile dysfunction, sometimes called "impotence," is the repeated inability to get or keep an erection firm enough for sexual intercourse. The word "impotence" may also be used to describe other problems that interfere with sexual intercourse and reproduction, such as lack of sexual desire and problems with ejaculation or orgasm. Using the term erectile dysfunction makes it clear that those other problems are not involved.
CIALIS
In clinical trials, CIALIS was shown to improve, up to 36 hours after dosing, the ability of men with ED to have a single successful intercourse attempt. CIALIS has not been studied for multiple sexual attempts per dose.
LEVITRA
Levitra is taken orally when needed between 4.30 hrs and 30 minutes before sexual activity. Take Levitra only as directed, usually once daily as needed. Levitra works along with sexual stimulation to help achieve an erection.
VIAGRA
This drug is taken by mouth as needed between four hours and one-half hour before sexual activity (about one hour before is most effective). Take only as directed, usually once daily as needed. Sildenafil works along with sexual stimulation to help achieve an erection.
