Q. Can I take Sildenafil as often as I want?

No, do not take Sildenafil for more than once a day. If you take more Sildenafil than the recommended dose then you may experience an increase in side effects and their severity.

Q. Why is the use of Sildenafil contraindicated with nitrates?

Use of Sildenafil is harmful for patients taking nitrates or blood pressure-lowering medicines as their combined use can cause a severe fall in blood pressure, which can also result in death.
