Warnings & Precautions

Taking sildenafil - or any other PDE5 inhibitor - won’t give you an instant erection. It usually takes an hour to kick in and will stimulate an erection only when you’re sexually aroused. This is helpful because this gives you more control over your erections and allows you to get an erection when the time’s right. After all, it would be pretty inconvenient to take a tablet that gives you an instant erection against your will. Sildenafil’s effects last for around four hours. It’s important to talk to a clinician before taking sildenafil to make sure that it’s safe for you to take and won’t interact with any medications you’re taking.

My “little blue pill” isn’t blue, it’s white. Is this normal?

Nonetheless, it’s still good to be aware of any potential side effects before taking any erectile dysfunction treatment (or any medication) for the first time, which is why we’ll outline them for you here. Sildenafil is a medicine used to treat erectile dysfunction symptoms. It belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors, which are usually the first types of medicines doctors prescribe to treat erectile dysfunction. Like other PDE5 inhibitors such as tadalafil and tadalafil daily, sildenafil is a prescription-only erectile dysfunction treatment. This means you can only get it once your health and medication history has been assessed by either a doctor or clinician.

If sildenafil is right for you, our clinicians are often able to prescribe it the same day and have it discreetly delivered to you within 24 hours. Sildenafil works by helping to relax the blood vessels in your penis, allowing blood to flow in when you’re sexually aroused and produce an erection. Contrary to common myth, the penis is not a muscle. You can’t get it hard simply by flexing it like you would a bicep. You should not take sildenafil if you are: Taking medicines called nitrates (which are often given for relief of angina pectoris [or “chest pain”]).

Instead, it’s a rod of spongey tissue that gets hard when blood flows into it. The more blood that flows into the penis, the harder it becomes. Think of it like a balloon, if that helps. By increasing the flow of blood to the penis, sildenafil can generate stronger erections in men with erectile dysfunction. Other PDE5 inhibitors work in a similar way, which is why they're so effective at treating ED.
