While our erectile dysfunction tablets usually work well for most men, some men may find that a particular ED treatment doesn’t give them the results they were hoping for. That’s why we give you the freedom to change your ED treatment prescription so that you can find the perfect treatment for your needs. All you need to do is email our clinical team and they will do their best to find you an alternative. If you change your erectile dysfunction medicine and it still doesn’t work for you, then it’s best to speak to your doctor as it may be a sign of an underlying condition that needs specific medical attention.
