Erectile Dysfunction

What is ED?

Erectile dysfunction, or ED, is when you can’t achieve or maintain satisfactory erections. Impotence is common, and becomes more common as men get older.

Who gets ED?

ED can affect men from age 30 and upwards and can be very distressing and frustrating for both men and their partners.

What causes ED?

Erection problems may be caused by non-medical problems such as tiredness, too much alcohol or recreational drug use, stress, depression or relationship problems. Medical causes include problems with blood flow to your penis, hormones, prostate problems or surgery, and certain medications.

For more detailed information see here.


There are treatments available. If you are having erection problems you should talk to a doctor to assess why this is happening so they can advise the correct treatment.

Sildenafil (Viagra) and Tadalafil (Cialis) are sometimes used to help with erection problems. They are not subsidised so you have to pay for it.

These treatments start working within 30 minutes to an hour. The medication will work faster if you take it on an empty stomach. You can then eat an hour after taking it without affecting how well it works.

What is the difference between Viagra and Cialis?

Viagra works for between 4-8 hours after you take them. You should take Viagra 1 hour before you attempt sex.

Cialis lasts for longer – about 36 hours – so are more suited if you need a longer-lasting treatment, for example, over a full weekend. Some people take Cialis every day at a low dose in the morning, so they don’t have to plan when they have sex.

You still need to feel sexually stimulated to get an erection when taking an erectile dysfunction treatment.

I took the tablet but nothing happened?

If you find that the medication didn’t work, you might want to consider whether you:

  • – waited long enough for the treatment to kick in
  • – waited too long for the medication to kick in
  • – had a high enough dose
  • – felt sexually aroused.

Is there any medication I can’t take with ED pills?

You cannot use GTN spray with ED tablets as it may cause you to collapse with low blood pressure. Also you should avoid drinking grapefruit juice or eating Seville oranges as these react with Sildenafil. For any concerns please discuss this with a SwiftMed doctor.
