Uses of Generic Sildenafil Citrate Tablets
Generic Sildenafil Citrate is used to treat male sexual function
problems (impotence or erectile dysfunction - ED). In combination
with sexual stimulation, Sildenafil works by increasing blood flow
to the penis to help a man get and keep an erection. To treat
erectile dysfunction-ED, take this drug by mouth as directed by
your doctor, usually as needed. Take Sildenafil at least 30 minutes,
but no more than 4 hours, before sexual activity (1 hour before is
the most effective).
Generic Sildenafil is also used to treat pulmonary arterial
hypertension and improve exercise capacity to improve exercise
ability and delay clinical worsening in men and women.

In combination with sexual stimulation, Sildenafil works
by increasing blood flow to the penis to help a man get

Warnings
Patients must not use Generic Sildenafil Citrate tablets or jelly in case
sexual activity is contraindicated due to their cardiovascular status.
Patients must stop taking this medicine and seek immediate medical
attention in case a sudden loss of vision occurs in one or both eyes,

(NAION).

Warnings
Use Sildenafil Citrate with caution in patients with anatomical
deformation of the penis (e.g., angulation, cavernosal fibrosis, or
Peyronie's disease) or in patients who have conditions, which may
predispose them to priapism (e.g., sickle cell anemia, multiple myeloma,
or leukemia).
In the case of an erection that lasts for more than 4 hours, the patient
should seek immediate medical treatment.
In case priapism (painful erection greater than 6 hours in duration) is
not treated immediately, penile tissue damage and permanent loss of
potency could occur.

Erectile Dysfunction Treatment with Generic Sildenafil Citrate
Medications
Warnings
Patients should stop using Generic Sildenafil Citrate and seek
immediate medical care in the case of sudden decrease or loss of
hearing.
Caution is advised when Generic Sildenafil Citrate is co-administered
along with alpha-blockers or anti-hypertensives. Using both the
medicines at the same time can lead to hypotension.
Decreased blood pressure, syncope, and prolonged erection can take
place at higher Sildenafil Citrate exposures.
In patients taking strong CYP inhibitors, such as Ritonavir, Sildenafil
exposure is increased. Decrease in Generic Sildenafil Citrate dosage is
recommended.

nose.
Seek immediate medical care in case of the following rare but serious

breath, wheezing or difficulty breathing; swelling of the face, lips, tongue or
other parts), chest pain, sudden decrease or loss of hearing, seizures, fits or

Overdose
In studies conducted with healthy volunteers of single doses of
Sildenafil Citrate up to 800 mg, adverse reactions were similar
to those observed at lower doses but incidence rates and
severities were increased.
In cases of overdose of Generic Sildenafil Citrate, standard
supportive measures must be used as necessary.

Sildenafil Citrate is highly bound to plasma proteins and it is
not eliminated in the urine.
