The duration of action of Fildena 150 mg, like other sildenafil-based medications, can vary from person to person. However, on average, its effects typically last for about 4 to 6 hours. During this time, you may find it easier to achieve and maintain an erection when sexually stimulated. Keep in mind that individual responses can vary, and some people may experience effects that last longer or shorter than this average duration.

It's important to note that the medication's effects do not mean you will have an erection for the entire duration of its action; instead, it means you will have an improved ability to respond to sexual stimulation with an erection during this time frame. Once the effects wear off, your ability to maintain an erection will return to its usual state.

Remember that Fildena 150 mg should be taken as prescribed by a healthcare professional, and you should not take more than one dose in a 24-hour period to avoid potential side effects and risks. If you have concerns about the duration of its effects or any other aspect of using this medication, it's best to discuss them with your doctor.
