If it doesn't seem to work
ED medicines need sexual arousal to work, and it can take a few attempts to find what works for you. If treatment isn't working, don't take extra tablets. Taking more than prescribed can be dangerous. Speak to your prescriber, who may review the medicine, strength or timing.
Repeat prescriptions
Online pharmacies usually ask you to review your health information again before a repeat supply. Tell them about any new medicines or health changes.
Switching pharmacy
You can change pharmacy. A new pharmacy will carry out its own consultation, so give it your full, accurate history, including what you've taken before and how it went.
Side effects
Tell your prescriber about side effects that bother you or don't go away. See common side effects and urgent warning signs.
