Product Description

Revatio is an erectile dysfunction medication that is also prescribed for patients who suffer from pulmonary arterial hypertension (PAH). Revatio contains the active component Sildenafil which helps in the treatment of PAH and ED. The other popular brand name of sildenafil is Viagra. However, it has to be kept in mind that that the drug is intended only for adults, hence children should never be given this medication.


The normally suggested dosage of Revatio is close to 5 mg or 30 mg taken thrice in a span of 24 hours. Revatio dosage needs to be administered with a gap of four to six hours. In the clinical trials performed using the medicine not much efficiency was achieved by increasing the dosage level.

One should definitely refrain from exceeding 20 mg of Revatio thrice in a day and it may lead to some adverse consequences.

Revatio injection is given priority for people who are unable to take up the oral form of the medication presently. If the medication is administered in a manner of intravenous bolus injection it should be three times in a given day with the dosage level of 2.5 mg or 10 mg.

The patients need not be concerned about modifying the dosage with respect their weight. The similar pharmacological effect offered by sildenafil is thought to be experienced by taking a 10 mg dose of Revatio. The effect felt also is equal to that of experienced by taking 20 mg of N-desmethyl metabolite taken orally.
