Sildenafil Side Effects, Overdose and Pregnancy Information
Sildenafil side effects include acid
indigestion, diarrhea, flushing, headache, and nasal congestion. Rare Sildenafil side
effects may include blindness, heart attack, stroke, high blood pressure,
asthma, asthma, and sudden death. Heart attack, stroke, sudden rise in blood pressure, and sudden
death have all been reported usually in men with pre-existing heart
problems. Recently some patients have reported blindness after using Sildenafil
(Viagra), though such cases are rare.
SILDENAFIL SIDE EFFECTS REPORTING
If you experience any Sildenafil side effects not mentioned above you should report it to your primary health care provider or FDA 1-800-FDA-1088 in the United States, Health Canada 1-866-225-0709 in Canada, MHRA 020 3080 6000 in UK, or TGA 1800 020 653 in Australia.
Sildenafil is prescribed to treat male sexual impotence also
known as ED (Erectile Dysfunction). Sildenafil was the first drug
that came out for impotence. Sildenafil works by controlling the
enzyme Phosphodiesterase TYPE 5(PDE5), which in turn causes higher level
of Nitric oxide that dilates blood vessels in the male organ by allowing
the influx of blood needed to sustain an erection.
Sildenafil is effective only during sexual arousal. Sildenafil
citrate does not work in the absence of libido. For best results use
Sildenafil approximately 1 hour before sexual activity, though for
some people as little as half hour or as much as 4 hours are needed for
Sildenafil to function properly.
Sildenafil is effective in about 70% of men, though it is
effective only when poor blood circulation is the cause of the ED.
SILDENAFIL OVERDOSE
No overdose of Sildenafil has been reported as of yet.
However, any medicine taken in excess can have grave consequences. If you
suspect Sildenafil overdose, seek medical attention right away. If you miss a dose of Sildenafil, take it as soon as you can. However, if it is just about time for your next dose, skip the one you forgot and go on with your regular schedule. Never take a double dose of Sildenafil.
SILDENAFIL DOSES
Sildenafil doses range from 25mg-100mg. The usual dose is 50mg. Your physician will adjust the dosage if you are over 65, have liver or
kidney problems, or are taking erythromycin, ketoconazole, itraconazole,
ritonavir, or saquinavir. A dose of 25mg may be adequate in that case.
Take Sildenafil only before sexual activity. The
manufacturer recommends a maximum of 1 dose per day. To avoid a sudden drop in blood pressure, do not take the
50mg-100mg dose of Sildenafil within 4 hours of taking an
alpha-blocking drug such as Cardura.
SILDENAFIL WARNING
People with pre-existing heart related problems such as severe high
or low blood pressure, heart failure, or unstable angina or those taking
medications called nitrates should avoid using Sildenafil.
If you take Sildenafil and experience cardiac symptoms like
dizziness, lightheadedness, nausea, or chest pain during sexual activity,
stop immediately. Alert your physician as soon as possible.
If you have a condition that might result in long-lasting
erections, such as sickle cell anemia, multiple myeloma, Peyronie's
disease or leukemia, use Sildenafil with caution. If an erection
lasts more than 4 hours, seek medical help immediately.
Use caution if you have a bleeding disorder, a stomach ulcer, or
the inherited eye condition known as retinitis pigmentosa.
To avoid low blood pressure, do not take the 50mg-100mg dose of
Sildenafil within 4 hours of taking an alpha-blocking drug such as
Cardura.
People with kidney or liver problem should begin with lower
doses.
SILDENAFIL CAUTION
Do not take Sildenafil if you are taking any nitrate-based
drug, including nitroglycerin patches, nitroglycerin ointment,
nitroglycerin pills, and isosorbide pills (Isordil). Combining Sildenafil
citrate with these drugs may result in a severe drop in blood
pressure.
If an allergic reaction happens with Sildenafil, stop
using it right away.
