From the Guidelines

Expired isotretinoin should not be used as its effectiveness and safety cannot be guaranteed. When isotretinoin (commonly known by brand names like Accutane or Roaccutane) expires, the medication may undergo chemical degradation, potentially reducing its therapeutic effectiveness in treating severe acne. The active ingredient may break down over time, especially if the medication has been stored improperly in conditions with heat, light, or humidity. While expired isotretinoin isn't typically dangerous, it may simply be less potent rather than harmful. However, given that isotretinoin is a powerful medication with serious potential side effects including birth defects, liver problems, and increased triglycerides, it's particularly important to use only as prescribed and within its shelf life. If you have expired isotretinoin, dispose of it properly through a medication take-back program or by mixing it with unpalatable substances like coffee grounds before placing it in the trash. Always consult with your healthcare provider for a new prescription rather than using expired medication, as recommended by recent guidelines 1. Key points to consider include:

  • Isotretinoin's effectiveness in treating severe acne, as supported by various studies 1
  • The potential for chemical degradation of the medication over time, especially when stored improperly
  • The importance of proper disposal of expired medication to prevent misuse or accidental ingestion
  • The need for consultation with a healthcare provider for a new prescription, ensuring the patient receives effective and safe treatment for their acne.

From the Research

Isotretinoin Expiration

  • There is no direct information available on what happens when isotretinoin expires 2, 3, 4, 5, 6.
