Possible uses of this
medication
Viagra is used to treat male sexual function problems
(erection problems).
How to take this medication
Viagra is taken by mouth as needed between 4 hours
and half an hour hour before sexual activity (about 1
hour before is most effective). Take only as directed,
usually once daily. Sildenafil works along
with sexual stimulation to help achieve an erection.
Side Effects
Headache, stomach upset, flushing, nasal stuffiness,
diarrhea and dizziness might occur. If these effects
persist or worsen, notify your doctor promptly.
Precautions
Before using Viagra, tell your doctor your medical history,
including any allergies (especially drug allergies),
any penis conditions such as fibrosis/scarring, history
of painful/prolonged erection (priapism), sickle cell
anemia, blood system cancers (such as leukemia or myeloma),
or Peyronie's disease, eye problems (retina diseases).
kidney or liver disease, bleeding disorders or active
stomach ulcers, heart diseases, stroke or severe high
or low blood pressure. Limit alcohol intake, as it may
aggravate side effects of this drug. To avoid dizziness
and lightheadedness when rising from a seated or lying
position, get up slowly. The elderly may be more sensitive
to the side effects of this drug, therefore caution
is advised in this group.
Drug Interactions
Tell your doctor of all nonprescription and prescription
medication you may use, especially any nitrate medications
(e.g., nitroglycerin, isosorbide dinitrate), nitroprusside
(any "nitric oxide donor" medicines), cimetidine,
erythromycin, azole antifungals (e.g., itraconazole,
ketoconazole), mibefradil, rifamycins (e.g., rifampin)
or high blood pressure medicines.
Viagra ® (sildenafil citrate) is contraindicated in patients who are taking organic nitrates in any form at any time. Consistent with its known effects on the nitric oxide/cGMP pathway, Viagra ® was shown to potentiate the hypotensive effects of nitrates and its administration to patients who are concurrently using organic nitrates in any form is therefore contraindicated.
Missed Dose
Not applicable.
Storage
Store Viagra at room temperature between 59 and 86 degrees
F (15-30 degrees C) away from light and moisture. Keep
this and all medications out of the reach of children.
Notes
Do not share Viagra with others, since they may have
a problem that is not effectively treated by this drug.
Use of this drug does not protect against sexually transmitted
diseases (e.g., HIV, Hepatitis B, gonorrhea)
