ED medicines are usually tablets called PDE-5 inhibitors. They work by increasing blood flow to the penis during sexual stimulation. You still need arousal for them to have an effect – they are not "instant arousal pills."

Who Is Eligible?

ED medication is generally safe for many men when prescribed properly, including those with conditions such as diabetes or cardiovascular disease. However, it is not suitable for everyone.

You must not use ED tablets if:

You take nitrates or certain heart medications that lower blood pressure
You've been advised not to have sex for medical reasons
You've had recent serious heart events, unless a clinician has specifically cleared you
You are buying from unregulated or overseas sites (these may supply counterfeit or unsafe medication)

If you're unsure about your heart health, blood pressure, or you've developed new chest symptoms, you should speak to a clinician in person before using ED treatment.

Important:

Always answer the medical questionnaire honestly. This is vital for your safety.
