From the Guidelines

I strongly recommend using Orabase paste for the management of oral lesions or discomfort, with a typical prescription of Orabase Protective Paste, applying a small amount to affected areas in the mouth 3-4 times daily, especially after meals and before bedtime, as directed by your healthcare provider, usually for 7-14 days. The application process involves drying the affected area with a clean tissue, then placing a small dab of paste directly on the lesion and pressing gently to ensure adherence. It is essential to avoid eating or drinking for 30 minutes after application to allow the paste to form a protective barrier. Orabase works by creating a protective coating over oral sores or irritated tissue, shielding them from further irritation from food, beverages, and saliva, thereby allowing the underlying tissue to heal more effectively while providing temporary pain relief. The paste contains carboxymethylcellulose sodium that adheres to moist mucous membranes, creating a bandage-like effect. Some formulations may also contain benzocaine for additional pain relief, as seen in studies such as 1.

Key Points for Application and Use

  • Apply a small amount to affected areas in the mouth 3-4 times daily
  • Use especially after meals and before bedtime
  • Continue use until lesions heal or as directed by your healthcare provider, usually for 7-14 days
  • Dry the affected area with a clean tissue before application
  • Avoid eating or drinking for 30 minutes after application

Mechanism of Action and Benefits

Orabase paste creates a protective barrier over oral lesions, reducing further irritation and promoting healing. The carboxymethylcellulose sodium in the paste adheres to moist mucous membranes, creating a bandage-like effect. This mechanism is supported by various studies, including those focused on the management of oral mucositis and stomatitis, such as 1 and 1, which highlight the importance of protective measures and oral care in managing such conditions.

Considerations and Precautions

While Orabase is generally recommended for oral lesions and discomfort, it's crucial to follow the prescribed application instructions and to consult with a healthcare provider for specific guidance, especially in cases of severe oral mucositis or when undergoing treatments like chemotherapy or radiation therapy, as discussed in 1. Additionally, considerations for oral hygiene and the prevention of secondary infections are vital, as emphasized in the guidelines for managing oral and gastrointestinal mucosal injury.
