Pay close attention to the instructions on your prescription label, and ask your pharmacist or doctor to clarify any parts you don't understand. It is recommended to take Cenforce pills 30 to 60 minutes before scheduled sexual activity. It is not a long-term treatment for ED; it only works while the user is sexually excited. Sildenafil Citrate levels in the blood can rise as a result of consuming grapefruit or grapefruit juice. You might be more susceptible to adverse consequences as a result. If you have a history of heart issues or are taking blood pressure-lowering drugs, do not take the pill without first seeing a doctor.
