Which E.D. medication should I take?
The good news for men suffering from E.D. is that you have a variety of options, and REX MD carries the vast majority of them. Your online visit can help our doctors decide which medication is best for you, and you can pick a price plan that works for you as well. Sildenafil (generic Viagra) for instance, requires taking the medication 30-60 minutes in advance of sex. Tadalafil daily (generic Cialis daily) can be taken once a day.
Why do I need to check my blood pressure first?
Knowing your blood pressure is an important part of knowing whether you can take an E.D. medication. It can be dangerous to take most E.D. meds if your blood pressure is too high.
Your initial online visit will require that you enter your most recent blood pressure reading, from within the last 6 months. If you need to have your blood pressure measured, many pharmacies today offer free and easy clinically-verified blood pressure monitors.
Where can I get my blood pressure checked?
Many pharmacies in the U.S. will offer free blood pressure readings, many of which are automated. Higi can show you where a blood pressure monitor is near you, or you can call your nearest pharmacy to find out if they offer a system as well.
How fast do E.D. medications work?
E.D. medications vary in strength and action time, but most of the single-use products (like Viagra and Cialis) work within 30 minutes and for up to a few hours.
What is a “generic” drug?
A generic medication is one that is no longer protected by its original patents or government-mandated periods of exclusivity on the market. Viagra is chemically and generically known as sildenafil. 20 years after its first FDA approval at Pfizer, it is available generically. Generics are usually cheaper and more plentiful than their branded counterparts.
What is an “off-label” drug?
Off-label drugs are medications that may be FDA approved for one indication (disease or sickness) but are used for other things too. In the world of E.D., the most common example is sildenafil. Sildenafil is approved in 25, 50, and 100mg doses and tablets for E.D., but it’s also approved in a 20mg tablet for pulmonary arterial hypertension.
Doctors sometimes prescribe drugs for “off-label” uses because they may be cheaper or more convenient in different doses. With sildenafil, taking five 20mg tablets is equivalent to a 100mg tablet of Viagra’s dosage, but at a fraction of the cost.
Why do I see 20mg sildenafil when Viagra is 25, 50 or 100mg?
Viagra (sildenafil) in 25, 50 or 100mg doses and tablets was originally approved for Erectile Dysfunction.
Revatio (sildenafil) was approved in a 20mg tablet for the treatment of pulmonary arterial hypertension.
Today, both are available generically, and 20mg sildenafil tabs are often cheaper than Viagra. Taking five 20mg tablets can be cheaper than a 100mg Viagra tablet/dose, for example, but with the same effect. 20mg sildenafil is sometimes prescribed “off label” if a doctor deems it medically appropriate
