People with ED have difficulty achieving or maintaining an erection. It’s a widespread condition, but many people find it difficult to discuss.
The main component of sildenafil is sildenafil citrate. Inactive components include:
anhydrous calcium hydrogen phosphate
Viagra is just one branded variant containing sildenafil. Other products may use other inactive ingredients.
Another brand name drug containing sildenafil is Revatio. In addition to treating ED, Revatio treats pulmonary hypertension (PH).
Sildenafil belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. These inhibit the phosphodiesterase enzymes that degrade muscle tissue-relaxing molecules. This allows increased blood flow, which causes an erection.
However, it can help treat the symptoms of the condition.
The pills come in strengths of 25 milligrams (mg), 50 mg, and 100 mg. People usually take a 50mg pill about 1 hour before sex. Regardless of the dose, a person should not take sildenafil more than once a day.
The drug is fast-acting and its effects usually last about 1 hour. It is important to note that sildenafil does not produce an erection immediately and that sexual arousal is necessary for the drug to work. Sildenafil also does not affect sexual desire .
People are more likely to experience adverse drug reactions if they take more than the recommended amount.
Some common side effects of sildenafil include:
muscle aches and pains
Is it possible to take too much sildenafil? If a person overdoses on this drug, they should seek immediate medical attention.
It is important to note that sildenafil is not a form of contraception, so it does not prevent pregnancy. In addition, it does not protect against sexually transmitted infections.
A person with ED symptoms can take sildenafil if they discuss it with a healthcare professional first.
Sildenafil can also help people with pulmonary arterial hypertension. It works by relaxing and dilating the blood vessels in a person’s lungs, which helps blood flow.
Since sildenafil requires a valid prescription, the doctor will prescribe the appropriate dosage for the individual. A person should not take more than the prescribed dose.
ED can sometimes be a sign of an underlying condition. For this reason, men should contact a doctor if they have difficulty achieving or maintaining an erection.
Some conditions that can cause ED include:
Type 2 diabetes
high blood pressure
atherosclerosis, which refers to hardening of the arteries
