The Department of Health and Social Care (DHSC) has issued a medicine supply notification due to shortages of several buprenorphine transdermal patches, affecting both Relevtec and Bupeaze brands.

According to the notice, Relevtec patches at 35micrograms/hour, 52.5micrograms/hour and 70micrograms/hour strengths are out of stock until early August 2025. Additionally, Bupeaze 52.5micrograms/hour patches will be unavailable until early October 2025.

These transdermal patches, used primarily for managing chronic pain, deliver buprenorphine via a four-day (96-hourly) matrix formulation.

The supply issue has been categorised as Tier 2, indicating a medium impact on the health system.

Despite the disruption, alternative matrix formulation patches – including Bupeaze at 35 micrograms/hour and 70micrograms/hour, Carlosafine, and Transtec – remain available and are expected to support the increased demand during the shortage period.
