Filagra Oral Jelly contains sildenafil, which is a phosphodiesterase type 5 (PDE5) inhibitor. It works by increasing blood flow to the penis, helping men achieve and maintain an erection when sexually aroused. It's important to note that the timing of when you may experience an erection after taking Filagra Oral Jelly can vary among individuals. Generally, it is recommended to take sildenafil about 30 minutes to an hour before anticipated sexual activity, and the effects may last for several hours. However, sexual arousal and stimulation are still necessary for the medication to be effective. Simply taking the medication alone will not lead to an automatic erection; there needs to be sexual stimulation for the drug to work. It's crucial to follow your doctor's instructions and the recommended dosage guidelines for Filagra Oral Jelly. Additionally, discuss any concerns or questions you have about the medication with your healthcare provider, as they can provide personalized advice based on your health and medical history.
