Arestin (minocycline hydrochloride) microspheres are indicated as an antibiotic add-on to scaling and root planing (SRP) procedures for the reduction of periodontal pocket depth in adult patients with periodontal gum disease. Common side effects of Arestin include:

  • headache,
  • infection,
  • flu-like symptoms,
  • pain,
  • mouth irritation,
  • gum infection,
  • cavities,
  • dental pain,
  • gum inflammation (gingivitis),
  • swelling and sores inside the mouth,
  • sore throat, and
  • indigestion.

Arestin is a variable dose product, dependent on the size, shape, and number of pockets being treated. Arestin may interact with other drugs. Tell your doctor all medications and supplements you use. Use of tetracycline antibiotic medications such as Arestin during tooth development may cause permanent discoloration of the teeth, and should not be used in children or in pregnant or nursing women.

Our Arestin Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
