Although only 10% to 15% of men with erectile dysfunction seek
treatment, the recent introduction of two more erectile
dysfunction medications may prompt more men to seek help for an
often treatable condition. If erectile dysfunction is a symptom
of an underlying medical problem like diabetes or heart disease,
treating the problem sometimes improves erectile dysfunction
without a medication. But if more help is needed, men now have
three erectile dysfunction drugs available: Viagra, Levitra
(vardenafil), and Cialis (tadalafil) All three block the action
of an enzyme known as PDE5, to permit more blood flow to the
penis during sexual stimulation. More blood means a harder
erection.
What every man wants to know
How long before having sex should I take the
medication?
Most men get good results taking the medication about an hour
before anticipated intercourse. One study suggests that Levitra
was ten times more effective than Viagra in inhibiting PDE5, and
some research suggests that higher doses of Levitra may have a
faster effect.
How long will the medication last?
Viagra and Levitra typically improve erections for about 4 hours.
However, they should not be taken more than once daily. Cialis is
effective for 24 to 36 hours, and the advantage is obvious. You
can take your medication Friday night and be "good to go" for
much of the weekend.
It could take some experimentation, directed by your doctor,
to find the best option for you. These drugs are not recommended
for men who use nitroglycerin tablets or patches, and liver or
kidney impairment may preclude them, or affect the dosage you
take. Drug interactions are also possible.
