It is important to remember that taking too much of this medicine can lead to severe health complications, such as heart problems or seizures. If you think you have overdosed on cenforce, contact your doctor immediately. The medication works quickly, and you should notice results within 30 minutes of taking it. Once the erection has formed, it should last for around 4 hours. It is also important to be aware that you should not use any other medications while taking cenforce 100mg. This is because it can interfere with the effectiveness of the drug. Some people find that the medication takes longer to work for them, and they may need to wait for an erection to form before engaging in sexual intercourse. For this reason, it is important to be in the right mood before you begin taking cenforce.
