Viagra Storage Guide: MHRA Guidelines & Side Effects

Proper storage of Viagra is essential for maintaining its effectiveness and safety. The MHRA (Medicines and Healthcare products Regulatory Agency) provides specific guidelines for storing sildenafil-based medications to prevent degradation and ensure optimal therapeutic benefits. Understanding these requirements alongside potential side effects helps ensure safe, effective treatment for erectile dysfunction.

  • Store at room temperature (15-30°C) away from heat and moisture
  • Keep tablets in original packaging until ready to use
  • Protect from light and avoid bathroom storage
  • Check expiry dates regularly and dispose of expired medication safely

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 Storage Requirements and Side Effect Management

MHRA Storage Requirements for Viagra

The MHRA mandates specific storage conditions for sildenafil citrate (Viagra) to maintain pharmaceutical integrity. Store tablets at room temperature between 15-30°C, avoiding extreme temperatures that can affect the active ingredient. Keep medication in its original blister packaging until consumption, as this provides essential protection against moisture and light exposure.

Environmental Factors to Avoid

Bathrooms and kitchens are unsuitable storage locations due to temperature fluctuations and humidity. Direct sunlight can degrade sildenafil, reducing effectiveness. EverydayMeds recommends storing Viagra in a cool, dry cupboard away from children and pets. The bedroom drawer or living room cabinet typically provides ideal conditions.

Common Side Effects and Management

Viagra and its generic equivalent sildenafil share identical side effect profiles. Common reactions include headaches (affecting 10-15% of users), facial flushing, nasal congestion, and mild digestive upset. These effects typically resolve within 2-4 hours and often diminish with continued use. Staying hydrated and avoiding alcohol can minimise these reactions.

When to Seek Medical Attention

Rare but serious side effects require immediate medical attention. Contact emergency services if experiencing chest pain, sudden vision changes, or priapism (erection lasting over 4 hours). Sudden hearing loss, severe dizziness, or allergic reactions warrant prompt medical consultation. EverydayMeds patients can access our clinical team for advice regarding any concerning symptoms.

Medication Expiry and Disposal

Check expiry dates monthly and never use expired sildenafil. Degraded medication may be ineffective or potentially harmful. Dispose of expired tablets through pharmacy take-back programmes or designated medication disposal sites. Never flush medications down toilets or discard in household waste, as this can contaminate water supplies.

Choosing Between Viagra and Generic Sildenafil

EverydayMeds offers both branded Viagra and generic sildenafil at checkout, allowing patients to choose based on preference and budget. Both contain identical active ingredients and follow the same storage requirements. Generic sildenafil provides a cost-effective alternative whilst maintaining the same efficacy and safety profile as branded Viagra.

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.
