How long does Viagra last?« Back to Questions List
Viagra, also known as Sildenafil Citrate Tablets, is mainly used to improve erectile dysfunction in men, and its efficacy usually lasts for 2-4 hours. It is generally recommended to take it one hour before sexual life, because the peak time of oral concentration of this drug is usually 30-120 minutes, and the average peak time for most patients is about one hour. Studies have shown that the effective duration of this drug can last for four hours, but for most patients, it usually has a better therapeutic effect in the first two hours, and the effect in the last two hours is actually weaker. In addition, when taking drugs, it should be noted that drugs can only play a therapeutic role under the condition of sexual stimulation, so sexual stimulation can make drugs play a better role. It is recommended that patients must take it on an empty stomach or 2 hours after meals. If they eat high-fat and greasy food, the onset time will be significantly delayed. At the same time, they should not drink alcohol before and after taking medicine, nor take hot baths, so as to maintain a good mentality. |
