Sildenafil is a treatment for erectile dysfunction, a condition where a man finds it difficult to achieve or maintain an erection. The active substance, also called sildenafil, works by improving blood flow to the penis when a man is sexually aroused. It does not increase libido, but it supports the physical response to sexual stimulation.<\/p>\n
Originally developed for heart-related chest pain, Sildenafil was later found to be effective in treating erectile difficulties. It is often used under the brand name Viagra, although generic versions are equally effective. Sildenafil typically starts working within 30 to 60 minutes and can remain effective for about four hours, allowing for a more relaxed experience.<\/p>\n
The standard recommended dose is 50 mg, taken as needed before sexual activity. However, some people may benefit from lower or higher doses depending on individual tolerance and response. It should not be taken more than once per day and should be swallowed with water. A heavy meal can delay its effects.<\/p>\n
Common side effects may include headache, facial flushing, nasal congestion, and dizziness. More serious effects such as vision changes or prolonged erections are rare but require medical attention. Sildenafil should not be used with nitrate-containing medicines or certain blood pressure drugs due to the risk of severe blood pressure drops.<\/p>\n","protected":false},"excerpt":{"rendered":"
