There are a few different ED medications that are commonly prescribed and clinically proven to help treat ED. One of the most well-known and popular is Sildenafil, generic for Viagra. Sildenafil comes in doses of 25 mg, 50 mg and 100 mg, all meant to be taken orally as needed at least an hour before sex. If you’ve been prescribed Sildenafil 50 mg, you might be wondering why your doctor chose this dosage for you and its benefits and side effects, as well as whether it’s the best ED medication for your needs.
What is Sildenafil 50 mg?
Sildenafil is a generic version of the brand name drug Viagra. It is a PDE5 inhibitor that helps men treat erectile dysfunction by improving blood flow to the penis and relaxing the muscles in the penile tissue. Sildenafil comes in doses of 25 mg, 50 mg and 100 mg. Sildenafil 50 mg is commonly prescribed for men who are trying erection pills for the first time. Depending on severity of symptoms, medical history and tolerance to the drug, your doctor might increase your dosage to 100 mg or reduce it to 25 mg.
What is ED?
Erectile dysfunction, or ED, is a common condition that describes when a man is unable to attain or maintain an erection that is firm enough for sex. It’s estimated that about 40% of Australian men will experience ED at some point in their lives.
There are many different causes of ED, including physical factors, psychological factors and lifestyle factors. It’s important to identify and understand the underlying cause of ED before starting to take any ED medications.
How does Sildenafil 50 mg work to treat ED?
Sildenafil is a PDE5 inhibitor, a type of drug that blocks PDE5 enzymes from breaking down cyclic GMP chemicals. Cyclic GMP chemicals relax and widen the blood vessels in the penis and erectile tissue to allow blood to flow in and cause erections. So by blocking these PDE5 enzymes from taking action, men are able to attain and maintain erections that are firm enough for sex.
How long does Sildenafil 50 mg last?
It’s recommended to take Sildenafil 50 mg at least an hour before sexual activity. The medication usually stays in your system for about four to five hours. However, some men have reported achieving erections up to 12 hours after taking Sildenafil.
Sildenafil side effects
Like all prescription medications, Sildenafil does have some common side effects that are typically mild and not serious. These side effects include:
- Back and muscle pain
There are other mild side effects that can occur, but most of them could go away within a few days or a couple of weeks on the treatment. If you’re experiencing any side effects, talk to your doctor.
