Sildenafil is a common treatment prescribed for erectile dysfunction. It works by increasing the body’s blood flow to the penis during sexual arousal, helping achieve and maintain an erection more easily. 

Sildenafil is taken 30-60 minutes before you intend to begin sexual activity and requires sexual arousal to achieve the desired effects.


  • How long do Sildenafil tablets take to work?

    Taken in a single dose, Sildenafil typically works within 30 minutes of taking. Although its effects can be seen anywhere from 20 to 60 minutes after you take the tablet.

    Sildenafil can take different amounts of time to produce the desired effect depending on a number of factors. This can include the level of Sildenafil dose, such as 25mg, 50mg, or 100mg, as well as diet and alcohol consumption.

  • How regularly can I take Sildenafil tablets?

    Although Sildenafil can typically be taken as often as it is required, it is recommended not to take more than one erectile dysfunction medication treatment in 24 hours. It is also not recommended to take Sildenafil for more than four days a week.

  • What happens if Sildenafil doesn’t work?

    For some, it can take a few separate attempts of taking to see the effects of Sildenafil tablets. When sildenafil doesn't work during your first instance of use, it is recommended that you trial using Sildenafil on eight different occasions before increasing the strength or switching to an alternative erectile dysfunction treatment.

    Alternative erectile dysfunction treatments include Tadalafil (Cialis), Vardenafil and Levitra.

  • Can I take Sildenafil tablets if I have heart problems?

    If you suffer from heart problems or a heart condition, you should take caution before using Sildenafil and other erectile dysfunction medications. Sildenafil has the potential to put the heart under increased strain as a result of its vasodilative effects. Although Sildenafil tablets primarily target the penis’s blood vessels, this medication can also affect the heart’s blood vessels.

    If you have heart problems, please consult your GP before taking or buying Sildenafil.

  • When to take Sildenafil?

    As a single dosage erectile dysfunction medication, you can take Sildenafil as often as required. Although, you should not take more than one Sildenafil tablet, or other erectile dysfunction medication, within the same 24 hour period. It is not recommended to take Sildenafil more often than 4 days a week.

  • Who shouldn't take Sildenafil?

    Whether Sildenafil is suitable or not will depend on a number of individual circumstances, existing conditions, and symptoms - as well as their severity. Speak to one of our experts if this is the case.

Side Effects

There are possible risks of side effects when taking Sildenafil, as with any medication. Most side effects are quite mild and subside over time. Others may be more serious and should be reported to your GP right away if experienced when using Sildenafil. Please get in touch with a member of our team if you are worried about any potential side effects of Sildenafil.

Common side effects of Sildenafil may include:

  • Diarrhoea
  • Runny/stuffed nose
  • Flushing
  • Dizziness
  • Nosebleeds
  • Nausea
  • Headaches
  • Red and/or warm skin
  • Muscle pain or back pain

Where side effects are more serious, you should immediately stop taking Sildenafil and report these to your GP as a matter of urgency. More serious side effects of Sildenafil may include: 

  • Priapism after taking Sildenafil (an erection that will not go away). If your erection persists for more than 4 hours, seek immediate medical help. Priapism can lead to permanent damage to your penis.
  • Sudden loss of vision, either in both or one eye. This sudden vision loss can indicate a serious eye problem named non-arteritic anterior ischemic optic neuropathy.
  • Sudden hearing loss, or a decrease in hearing. Some may also experience tinnitus (ringing in the ears) or dizziness.
