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.
