Is Sildenafil prescription only?
Sildenafil, a generic version of Viagra, is one of the most popular drugs prescribed for treatment of erectile dysfunction. In the majority of countries it is provided by prescription.
This drug is also available on the Internet, but a special prescription is needed in this case too. However, in this case, a different doctor than your general practitioner provides you the prescription. This is called an online prescription.
Sildenafil is a medication with very strong effect so it must be used carefully. Only a doctor can determine whether you can take Sildenafil and what dosage is safe in your particular situation. Prescription cannot be issued without consultation.
A doctor makes decision depending on your medical history, medications you are currently taking and the general state of your health. If the doctor considers the use of Sildenafil safe and appropriate, you will receive a prescription which provides you an opportunity to buy Sildenafil.
Sildenafil is almost the best-known drug for treating erectile dysfunction. It provides a temporary relief to erection problems and improves blood circulation, assuring proper erection.
