Does Testogel Need to Be Kept in the Fridge?

No, Testogel does not need to be kept in the fridge. This is a common question among patients prescribed testosterone replacement therapy, and the answer is straightforward: Testogel should be stored at room temperature, not refrigerated.

Testogel (testosterone gel) is formulated to remain stable at normal room temperatures. According to the UK Summary of Product Characteristics (SmPC) and patient information leaflet, Testogel should be stored below 25°C. The product should be kept in its original packaging to protect from light and must not be frozen. Refrigeration is not required and may make the gel uncomfortably cold to apply.

The gel's active ingredient, testosterone, and its delivery system are designed to maintain potency and effectiveness when stored according to the manufacturer's instructions approved by the Medicines and Healthcare products Regulatory Agency (MHRA). There is no clinical benefit to refrigerating Testogel, and doing so does not extend its shelf life or improve its efficacy.

A suitable storage location is a cool, dry place away from direct heat sources such as radiators or windowsills exposed to sunlight—for example, a bedroom drawer or cupboard. The medication must be kept out of the sight and reach of children. Ensure the container is properly sealed after each use to maintain the medication's quality and ensure you receive the intended therapeutic benefit from each dose.

Proper Storage Conditions for Testogel

Correct storage of Testogel is essential to maintain its stability, efficacy and safety throughout its shelf life. The storage requirements are straightforward but must be followed consistently.

Temperature requirements: Store Testogel at room temperature. Do not store above 25°C. Avoid exposing the medication to excessive heat or freezing temperatures. Do not freeze. In the UK climate, most indoor environments naturally fall within safe storage limits.

Location considerations: Choose a storage location that is:

  • Cool and dry – avoid areas with high humidity or temperature fluctuations, such as bathrooms where steam from showers may affect the product

  • Away from direct sunlight and heat sources – keep in the original packaging to protect from light

  • Out of the sight and reach of children and pets – testosterone is a prescription-only medicine that can cause serious harm if accidentally ingested or applied by others

  • Secure – consider a locked drawer or cupboard, particularly in households with children

Container integrity: Always keep Testogel in its original packaging until use. The sachets or pump dispenser are designed to protect the gel from light and contamination. Once a sachet is opened, use the entire contents immediately—do not attempt to save partial sachets for later use. For pump dispensers, ensure the cap is replaced securely after each application. Do not transfer the gel to alternative containers.

Important safety note: Testogel is flammable until dry. Keep away from naked flames and do not smoke during and immediately after application. Allow the gel to dry completely on your skin before approaching heat sources.

What Happens If Testogel Is Stored Incorrectly

Incorrect storage of Testogel can compromise the medication's effectiveness and safety. The extent of impact depends on the nature and duration of improper storage.

Effects of excessive heat: If Testogel is exposed to temperatures significantly above 25°C—such as being left in a hot car, near a radiator or in direct sunlight—the gel's consistency may change and the active testosterone may degrade. The product might become thinner or separate. Prolonged heat exposure can reduce potency, potentially leading to suboptimal testosterone levels. If you notice any change in the gel's appearance, texture or smell, do not use it and consult your pharmacist.

Consequences of freezing: Testogel must not be frozen. Freezing may alter the formulation and affect how the testosterone is released and absorbed through the skin. If the product has been frozen, do not use it. Contact your pharmacist for a replacement.

Damaged or compromised packaging: If the packaging is damaged or the seal is broken, the gel's sterility or consistency may be affected. Do not use products with compromised packaging integrity.

Clinical implications: Using improperly stored Testogel may result in suboptimal testosterone levels, potentially leading to a return of hypogonadism symptoms such as fatigue, reduced libido or mood changes. If you suspect your Testogel has been stored incorrectly, contact your GP or pharmacist before continuing use. They can assess whether replacement is necessary and may arrange monitoring blood tests to ensure your testosterone levels remain therapeutic.

Always follow the storage instructions in the patient information leaflet supplied with your medication.

Travelling with Testogel: Storage Tips

Travelling with Testogel requires planning to ensure the medication remains effective and that you comply with transport regulations, particularly for air travel.

Domestic travel within the UK: When travelling by car or train, keep Testogel in a cool place, protected from excessive heat. Avoid leaving the medication in a parked vehicle, especially in warm weather, as interior temperatures can quickly exceed safe storage limits. A small insulated pouch can provide additional protection during transit, but do not use ice packs that could cause freezing.

Air travel considerations: Testogel can be carried in hand luggage or checked baggage. Important points to consider:

  • Carry in hand luggage when possible to maintain better temperature control and avoid loss

  • Declare at security – essential prescription medicines are exempt from the usual 100 ml liquid restrictions for hand luggage, but you should declare them at security screening and carry supporting evidence (prescription, patient information leaflet or GP letter)

  • Keep in original packaging – carry Testogel in its original box with the patient information leaflet and pharmacy label showing your name

  • Carry a prescription or GP letter – this can expedite security checks and is advisable for all travel

For detailed guidance, see GOV.UK advice on hand luggage restrictions and travelling with medicines.

International travel: Testosterone is a controlled substance in many countries. Check the regulations of your destination country well in advance, as some require advance notification, import permits or specific documentation. For travel outside the UK with controlled medicines, consult GOV.UK guidance on travelling with controlled drugs. Your GP surgery can provide a letter confirming your prescription and medical need. Contact the embassy or consulate of your destination country to confirm their requirements.

Climate considerations: If travelling to hot climates, store Testogel in the coolest part of your accommodation, away from windows and direct sunlight. An air-conditioned room provides suitable storage. Do not freeze the product. Maintain storage below 25°C where possible.

Time zone changes: Maintain your regular dosing schedule as much as possible, adjusting gradually if crossing multiple time zones. Consult your doctor if you need advice on timing doses during long-haul travel.

When to Dispose of Testogel

Knowing when and how to dispose of Testogel safely is important for both efficacy and environmental protection. Several situations warrant disposal of this medication.

Expiry dates: The most common reason for disposal is reaching the expiry date printed on the packaging. Do not use Testogel after the expiry date stated on the label. The manufacturer cannot guarantee the potency or safety of expired medication. Check expiry dates regularly, particularly if you have stockpiled supplies.

Changes in appearance or consistency: Dispose of Testogel if you notice:

  • Discolouration or unusual appearance

  • Separation of the gel that does not resolve

  • Unusual odour

  • Crystallisation or particles in the gel

  • Damaged, torn or compromised packaging

These changes may indicate degradation or contamination, and the product should not be used.

Treatment discontinuation: If your doctor advises stopping testosterone replacement therapy or switches you to an alternative formulation, return unused Testogel to your pharmacy for safe disposal. Do not keep it for future use or share it with others, as testosterone is a prescription-only medicine that requires medical supervision.

Safe disposal methods: Do not dispose of Testogel in household waste or pour it down sinks or toilets, as testosterone can contaminate water supplies and harm aquatic life. The correct disposal method is to:

  • Return unused or expired Testogel to any community pharmacy

  • Use the pharmacy's pharmaceutical waste disposal service (provided free of charge under NHS arrangements)

  • Keep the medication in its original packaging for identification

  • Note that used sachets or pump containers may contain residual gel; keep them out of reach of children and pets and return to a pharmacy where possible

Community pharmacies accept unwanted medicines and will ensure proper disposal. If you have concerns about disposal or large quantities to return, contact your GP surgery or pharmacist for guidance. Further information is available from NHS guidance on disposal of unwanted medicines.

Frequently Asked Questions

Can I keep Testogel in the bathroom cabinet?

It is not recommended to store Testogel in the bathroom. Bathrooms experience high humidity and temperature fluctuations from showers and baths, which can affect the gel's stability and consistency. Choose a cool, dry location such as a bedroom drawer or cupboard instead.

What should I do if my Testogel has been left in a hot car?

If Testogel has been exposed to excessive heat in a car, check for changes in appearance, texture or smell. If you notice any alterations, do not use the product and contact your pharmacist for a replacement. Prolonged heat exposure can degrade testosterone and reduce the medication's effectiveness.

Can I take Testogel through airport security in my hand luggage?

Yes, Testogel can be carried in hand luggage as it is an essential prescription medicine exempt from the usual 100 ml liquid restrictions. Declare it at security screening and carry it in its original packaging with your prescription or a GP letter to expedite checks.

How long does Testogel last once opened?

Individual Testogel sachets should be used immediately once opened—do not save partial sachets for later use. For pump dispensers, ensure the cap is replaced securely after each application and use before the expiry date printed on the packaging.

Is Testogel the same as other testosterone gels like Tostran?

Testogel and Tostran are both testosterone gels used for replacement therapy, but they differ in concentration and application method. Both require similar storage conditions at room temperature below 25°C. Your doctor will prescribe the formulation most suitable for your needs based on dosing requirements and individual response.

Where do I return unused or expired Testogel?

Return unused or expired Testogel to any community pharmacy for safe disposal free of charge under NHS arrangements. Do not dispose of testosterone gel in household waste or pour it down sinks or toilets, as it can contaminate water supplies and harm aquatic life.
