What medications are known to help with ED?

The four well known oral medications are as follows:

  • Sildenafil (Viagra)
  • Tadalafil (Cialis)
  • Vardenafil (Levitra)
  • Avanafil (Spedra)

The listed medications increase the effects of nitric oxide which is a natural chemical produced by the body which relaxes the muscles in the penis. This subsequently increases blood flow and allows for an erection to form in response to sexual stimulation. The medication listed above do not automatically cause an erection; sexual stimulation is needed to allow for the release of nitric oxide for the medications to amplify its effect.

Can ED be prevented?

Various lifestyle activities can be implemented to help reduce ED. Examples include, having a healthy lifestyle, exercising, eating the right foods, stopping smoking and reducing consumption of alcohol. For those with certain conditions such as Diabetes, implementing the above strategies and ensuring blood sugar is controlled also contributes to reducing the prevalence of Erectile dysfunction. If you have any concerns then it is advisable to get help by visiting you GP to discuss the problem. If the root cause is psychologically related then counselling might be an option to pursue.

There are many ways in which you can take the emphasis away from erectile dysfunction specifically. Although intercourse is enjoyable and important, consider developing other forms of sexual intimacy which can still prove to be extremely pleasurable and help ignite or maintain the ‘spark’ in your relationship.

Do not be afraid to seek help and advice if you feel ED is affecting your mental or physical health. Talking to the right person (someone you feel comfortable with or with a healthcare professional) will help you decide how best to approach the situation.

Do not buy supplements or ‘aphrodisiacs’ through unwarranted websites, especially those preparations with unsubstantiated claims.

Do not blame yourself or your partner for your ED. It’s a health problem and should be treated as such. It’s not a problem to be ashamed of.
