Does Sildenafil Expire? Everything You Need to Know

Sildenafil, commonly sold under its brand name Viagra, is a medication used to treat erectile dysfunction (ED) and pulmonary arterial hypertension (PAH). It is one of the most popular medications for ED, but the concern of its expiry date often arises amongst its users. This article will answer some FAQs regarding the expiry date of sildenafil.

What is the Expiry Date of Sildenafil?

Like any medication, sildenafil also has an expiry date. The expiry date is printed on the packaging of the medication. However, once its expiry date has passed, it is not an indication that the medication is no longer safe to use or will be ineffective.

Does Sildenafil Lose Its Potency After Its Expiry Date?

Sildenafil's chemical composition may break down or degrade beyond its expiry date, which can cause it to become less effective. However, the loss in potency depends on various factors such as how it was handled, the environment it was stored in, and the manufacturing process.

Some studies have found that sildenafil may retain its potency for several years past its expiry date, but it may not provide similar results as when it was in date. Hence, it is better to use the medication as advised by the packaging label.

Should Expired Sildenafil be Discarded?

What Happens if I Take Expired Sildenafil?

Taking expired sildenafil isn't necessarily harmful, and it may still provide some effects.

However, individuals with underlying medical conditions may have different reactions to the medication.
