MHRA Sildenafil Storage & Handling Guide

Proper storage of sildenafil tablets is essential for maintaining their effectiveness and safety. The MHRA provides specific guidelines for storing both branded Viagra and generic sildenafil safely at home. Following these storage recommendations helps ensure your ED medication remains potent throughout its shelf life. EverydayMeds offers both Viagra and generic sildenafil options, with the same storage requirements applying to both formulations.

  • Store sildenafil tablets at room temperature (15-25°C) away from heat and moisture
  • Keep tablets in original packaging until ready to use to protect from light
  • Never store in bathroom cabinets or car glove compartments due to humidity and temperature fluctuations
  • Check expiry dates regularly and dispose of expired tablets safely through local pharmacy return schemes

How ED treatment works in your body.

Increases blood flow

Increases blood flow

When PDE5 is suppressed, blood is able to flow more freely through the body—including to the (you guessed it) penis.

Increase erections

Increase erections

More blood flow to the penis means harder, more satisfying erections once you're sexually stimulated.

Complete Sildenafil Storage Requirements

Temperature and Environmental Controls

Sildenafil citrate, whether in branded Viagra or generic form, requires storage at controlled room temperature between 15-25°C (59-77°F). The active ingredient degrades when exposed to excessive heat or cold, potentially reducing effectiveness. Avoid storing tablets near radiators, in direct sunlight, or in freezing conditions such as garages during winter months.

Humidity and Moisture Protection

Moisture can cause sildenafil tablets to deteriorate or stick together, making them unsafe to use. The bathroom medicine cabinet, despite being convenient, creates the worst storage environment due to steam from showers and baths. Similarly, kitchen storage near dishwashers or kettles should be avoided. A bedroom drawer or dedicated medicine box in a dry area provides optimal conditions.

Light Protection and Original Packaging

MHRA guidelines emphasise keeping tablets in their original blister packaging until consumption. The aluminium backing and plastic forming protect sildenafil from UV light degradation. Never transfer tablets to pill organisers or different containers unless specifically advised by your pharmacist. The original packaging also maintains important information including batch numbers and expiry dates.

Safety Considerations for Household Storage

Store sildenafil securely away from children and pets, as accidental ingestion can cause serious health complications. Consider using a locked medicine box if young children have access to storage areas. EverydayMeds supplies both Viagra and generic sildenafil in child-resistant packaging, but additional precautions remain advisable.

Expiry Dates and Disposal

Check expiry dates every few months and never use sildenafil past its indicated date. Expired medications may lose potency or develop harmful breakdown products. UK pharmacies, including participating EverydayMeds partner locations, accept unused medicines for safe disposal through the NHS Returns Scheme, preventing environmental contamination from household waste disposal.

What you need to know about erectile dysfunction

It's one of the most common conditions we treat, and one of the most treatable.

What is Erectile Dysfunction?
ED means finding it hard to get or keep an erection firm enough for sex. It's not unusual to have an off night; the point at which it's worth doing something is when it's happening regularly, or when it's starting to bother you.
How will I feel when I take ED medication?
For most men, nothing feels different day to day. The medication works in the background — when you're sexually aroused, it helps blood flow where it's needed, so erections come more easily and last longer. It doesn't cause arousal on its own. Some men notice mild, short-lived effects like a headache, facial flushing or a stuffy nose, which usually pass as the dose wears off.
Why do I need a prescription for ED medication?
ED treatments are prescription-only medicines in the UK because they aren't suitable for everyone — for example, alongside certain heart conditions or medications like nitrates. That's why we ask you to complete a short online consultation first. A UK-registered prescriber reviews your answers to make sure your chosen treatment is safe and right for you before it's dispensed.
