Bausch Health's OraPharma Celebrates 25 Years of ARESTIN® (minocycline HCl) Microspheres

The only FDA‑approved locally applied antibiotic used with scaling and root planing (SRP) marks a quarter‑century of clinical use

LAVAL, QC, Feb. 19, 2026 /PRNewswire/ -- Bausch Health Companies Inc. (NYSE:BHC)(TSX:BHC), and its dental products business, OraPharma, today announced the 25th anniversary milestone of ARESTIN® (minocycline HCl) Microspheres, 1 mg, a locally administered antibiotic used as an adjunct to scaling and root planing (SRP) for the reduction of pocket depth in adult patients with periodontitis. ARESTIN is supported by over two decades of clinical experience and remains the only Food and Drug Administration (FDA) approved locally applied antibiotic for this use.

Dan Wu, Ph.D., Senior Director, Pharmaceutical Sciences & Technology, Bausch Health, and a member of the development team behind ARESTIN, reflected, "The 'why' behind developing ARESTIN began with recognizing that periodontal disease is a localized, chronic bacterial condition and that clinicians had no targeted way to help address it. There was a gap in treatment, and ARESTIN was developed to help fill that need by delivering antibiotic therapy directly into the periodontal pocket, using tiny microspheres that release the antibiotic gradually over time before naturally biodegrading."

Periodontal disease remains one of the most prevalent chronic oral health conditions globally, affecting more than one billion people¹. As part of comprehensive periodontal disease management, many dental professionals have incorporated ARESTIN with scaling and root planing (SRP).

"Reaching Arestin's 25-year milestone as the only FDA-approved locally applied antibiotic reflects our commitment to periodontal care," said Tom Stern, Vice President and General Manager of the OraPharma business, Bausch Health's dentistry division. "As we recognize this legacy, we are equally focused on the future—one defined by innovation and deeper collaboration with the dental community. Building on Arestin's impactful history, we continue to support non-surgical periodontal treatment for appropriate patients."

OraPharma continues to advance its commitment to periodontal health, including recent commercial expansion into Canada and Puerto Rico aimed at improving access to treatment options in areas with unmet needs.

What is ARESTIN?
ARESTIN® (minocycline HCl) Microspheres, 1mg is used in combination with scaling and root planing (SRP) procedures to treat patients with adult periodontitis (gum disease). ARESTIN® may be used as part of an overall oral health program that includes good brushing and flossing habits and SRP.

IMPORTANT SAFETY INFORMATION

• Do not use ARESTIN if you are allergic to minocycline or tetracyclines, ask your dentist if you are not sure. Do not use ARESTIN in children, pregnant or nursing women as the use of tetracycline class drugs, including ARESTIN, during tooth development may cause permanent discoloration of the teeth.
• ARESTIN may cause you to be sensitive to sunlight. Patients exposed to direct sunlight or ultraviolet light may develop a severe sunburn. At the first evidence of skin redness, call your dentist.

• Tetracyclines, including oral minocycline, have been associated with the development of autoimmune syndromes with symptoms such as joint pain, muscle pain, rash, swelling, fever, enlarged lymph nodes, and general body weakness.
• Tell your dentist about all the medicines you take, and about any health problems you have, including if you've had oral candidiasis ("thrush").
• ARESTIN has not been studied in patients with weakened immune systems, such as patients with HIV infections or diabetes, or those receiving chemotherapy or radiation.
