Tri-Solfen is a local anaesthetic and antiseptic gel spray for use on lambs to provide pain relief following mulesing and tail docking and on lambs and calves to provide pain relief during and following castration.

The product contains two proven topical local anaesthetics; fast-acting Lignocaine for immediate pain relief and long-acting Bupivacaine for prolonged post-operative pain relief. Adrenaline is included for its ability to reduce the shock and stress of blood loss, whilst prolonging the anaesthetic action. Tri-Solfen also contains Cetrimide, an antiseptic widely used to cleanse skin and wounds and provides protection from bacterial contamination. The product's gel base adheres well to the wound and acts as a barrier to environmental
stimuli to improve wound healing.

Active Constituents: Lignocaine (as hydrochloride) 40.6g/L , Bupivacaine (as hydrochloride) 4.2g/L , Adrenaline (as tartrate) 24.8mg/L , Cetrimide 5g/L

Directions for Use




DO NOT USE this product except as a one-off post-mulesing treatment of lambs that are to be kept for wool production.

Apply Tri-Solfen spray to the wound immediately after mulesing using the special Tri-Solfen applicator as per the figure below. The applicator applies 2mL per spray.

Apply the Tri-Solfen as a series of stripes up and down the wound for full cover of the wound, edges and tail. Do not spray to run-off.





Insecticidal preparations registered to treat mulesing wounds can be applied AFTER application of Tri-Solfen. However high volume fly treatments are not suitable to be used as they are likely to wash the Tri-Solfen from the wound.
