Compounding dental mouthwashes or rinses may offer numerous advantages over commercially available dosage forms. Elixirs, syrups, and suspensions often contain preservatives such as alcohol which can cause reactions or gastrointestinal irritation, or sugar which makes the preparation undesirable for prolonged use in the mouth or for diabetic patients. A customized preparation without unnecessary excipients – i.e., a sugar-free, dye-free, lactose-free, and preservative-free dosage form – can eliminate concerns of palatability, alcohol content, and dyes which may stain exposed mucosa.
Various preparations are also available to treat burning mouth syndrome and anesthetic/analgesic and antibiotic/anti-infective mouthwashes are commonly requested.
Tranexamic acid solution (4.8%) used as a mouthwash has been used successfully to prevent postsurgical bleeding after oral surgery without dose modification of oral anticoagulants.
