Avaforce 50 mg has a relatively rapid onset of action compared to some other PDE5 inhibitors. It typically starts to work within 15 to 30 minutes after administration, making it a quick-acting option for ED treatment. Avaforce 50 mg is usually taken orally with a full glass of water, about 15 to 30 minutes before anticipated sexual activity. It can be taken with or without food. Avaforce 50 mg, like other PDE5 inhibitors, does not cause spontaneous erections. Sexual arousal or stimulation is necessary for the medication to be effective.
