Sildenafil is the cheapest option

Of the medications available for erectile dysfunction that contain sildenafil citrate, generic Sildenafil is the best value for money and works exactly the same as more expensive brands.

Dosages of Sildenafil

Sildenafil comes in 3 doses:

  • 50mg – the standard dosage to start with
  • 25mg – you can consider switching to this if you get side effects from 50mg
  • 100mg – you can consider switching to this if the effect of 50mg is not strong enough

Things to avoid when taking Sildenafil

  • Heavy meals – Sildenafil works best on an empty stomach. It won’t get to work as fast after eating a heavy, high-fat meal
  • Grapefruit juice – drinking grapefruit juice while taking Sildenafil can increase your chances of getting side effects
  • Changing your dosage on your own – do not start, stop, or change your intake of Sildenafil tablets without first discussing it with your doctor
  • Alcohol – although alcohol may make you less nervous it can stop Sildenafil working effectively and makes erections less likely in general
  • Amyl nitrites (poppers) – these can interact with Sildenafil and can cause potentially serious side effects

Side effects of Sildenafil

When using this medication, you may experience one or more of the following, common Sildenafil side effects:

  • Dizziness/ lightheadedness
  • Headache
  • Flushing
  • Heartburn or indigestion
  • Nosebleeds or nasal congestion
  • Trouble sleeping
  • Oedema (swollen hands, ankles or feet)
  • Visual disturbances (blurred vision/ increased sensitivity to light/ blue-green colour blindness)
