COMMON BRAND NAME(S): Viagra |
IMPORTANT NOTE: The following
information is intended to supplement, not substitute for,
the expertise and judgment of your physician, pharmacist or
other healthcare professional. It should not be construed
to indicate that use of the drug is safe, appropriate, or
effective for you. Consult your healthcare professional before
using this drug.
|
This medication is used to treat male sexual function problems
(erection problems).
|
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.
|
Headache, flushing, stomach upset, nasal stuffiness, diarrhea
and dizziness might occur. If these effects persist or worsen,
notify your doctor promptly. Unlikely but report promptly: painful
or other urination problems, vision problems, skin rash. Very
unlikely but report promptly: chest pain, fainting, foot or
ankle swelling. If you experience a painful or prolonged erection
(lasting longer than 4 hours), stop using this drug and seek
immediate medical attention. If you notice other effects not
listed above, contact your doctor or pharmacist.
|
Before using this drug, tell your doctor your medical history,
including: allergies (especially drug allergies), penis conditions
such as fibrosis/scarring (e.g., Peyronie s disease), history
of painful/prolonged erection (priapism), sickle cell anemia,
blood system cancers (such as leukemia or myeloma), eye problems
(retina diseases), kidney or liver disease, bleeding disorders,
active stomach ulcers, heart disease, stroke, very high or low
blood pressure. Limit alcohol intake, as it may aggravate side
effects of this drug. Since this drug may cause dizziness, caution
is advised when performing tasks requiring alertness (e.g.,
driving). To avoid dizziness and lightheadedness when rising
from a seated or lying position, get up slowly. This drug is
not to be used in women or children. The elderly may be more
sensitive to the side effects of this drug, therefore caution
is advised in this group.

isosorbide dinitrate), nitroprusside (any nitric oxide donor
medicines), cimetidine, erythromycin, azole antifungals (e.g.,
