From the Guidelines

Triamcinolone dental paste should not be used on the lips without caution and healthcare provider guidance, as it is designed for oral use and may cause skin thinning or other adverse effects with prolonged use. The primary use of triamcinolone acetonide 0.1% in adhesive paste (such as Adcortyl in Orabase) is for treating oral erosions and ulcers, as stated in the guidelines for managing pemphigus vulgaris 1. When considering its use on the lips, it is essential to weigh the potential benefits against the risks, including skin thinning, increased risk of fungal infections, or systemic absorption of the steroid.

If a healthcare provider recommends using triamcinolone dental paste on the lips, it is crucial to follow their guidance and use a small amount (about the size of a grain of rice) directly on the affected area up to 2-3 times daily after meals and before bed. Avoid ingesting food or drink for 30 minutes after application to allow the medication to work. The paste contains a corticosteroid that reduces inflammation by suppressing the immune response in the affected tissue. However, prolonged use (beyond 7-10 days) should be avoided, and patients should be monitored for any adverse effects.

Key considerations for using triamcinolone dental paste on the lips include:

  • Starting with a low frequency of application and gradually increasing as needed and under healthcare provider guidance
  • Monitoring for signs of skin thinning, fungal infections, or other adverse effects
  • Avoiding prolonged use beyond 7-10 days to minimize the risk of adverse effects
  • Consulting a healthcare provider if symptoms persist or worsen after a few days of use for further evaluation and guidance.
