Question

Do meds only go bad in extreme heat? Or can they also go bad if kept in extreme cold temperatures such as the crisper drawer in the fridge if the temperature setting in the fridge is too low i.e 0°C?

Answer 1

Medications can go bad or degrade when exposed to extreme temperatures, both hot and cold. Most medications have specific storage recommendations provided by the manufacturer, and it's essential to follow these guidelines to ensure their effectiveness and safety.

1. Extreme Heat: High temperatures can accelerate the degradation of medications. When medications are exposed to excessive heat, the chemical composition can change, leading to reduced potency and potential side effects. Avoid leaving medications in hot cars, direct sunlight, or near heat sources.

2. Extreme Cold: Cold temperatures can also affect the stability of medications, although this is less common than heat-related issues. Some medications may be sensitive to freezing temperatures, and when frozen, their composition can be altered, rendering them ineffective. Additionally, freezing and thawing may cause changes in the drug's physical properties, like texture and appearance, indicating potential degradation.

Regarding your specific example of storing medications in the crisper drawer of a fridge at 0°C, it's essential to be cautious. While refrigeration is appropriate for some medications, others may not tolerate such cold temperatures well. Some medications come with specific storage instructions that mention avoiding refrigeration, as it can lead to degradation.

To properly store medications, consider the following tips:

• Follow the storage instructions provided with the medication or on the label.
• If refrigeration is recommended, store medications in the main body of the refrigerator, not in the freezer or crisper drawer, as the temperatures there can be colder than the optimal storage range for some medications.
• Keep medications away from direct light, moisture, and heat sources like stoves and radiators.
• If you have any doubts about the storage requirements of a particular medication, consult your pharmacist or healthcare provider for guidance.

Remember, expired or degraded medications may not be as effective and can potentially be harmful. Always check the expiration date on medication packaging, and dispose of any expired or questionable medications properly. If you are unsure about the quality of a medication due to temperature exposure, it's best to contact your healthcare provider or pharmacist for advice.
