(1) While holding plunger, turn the knurled ring on the plunger turn to the left and slide it so the side nearest the barrel is at the prescribed weight marking. (2) Lock the ring in place by making a turn to the right. (3) Make sure that the horse's mouth contains no feed. (4) Remove the cover from the tip of the syringe. (5) Insert the syringe tip into the horse's mouth at the space between the teeth. (6) Depress the plunger as far as it will go, depositing paste on the back of the tongue. (7) Immediately raise the horse's head for a few seconds after dosing.

Discussion:
Parasite Control Program: All horses should be included in a regular parasite control program with particular attention being paid to mares, foals and yearlings. Foals should be treated initially at 6 to 8 weeks of age, and routine treatment repeated as appropriate. Consult your veterinarian for a control program to meet your specific needs. ZIMECTERIN (ivermectin) Paste effectively controls gastrointestinal nematodes and bots of horses. Regular treatment will reduce the chances of verminous arteritis caused by S vulgaris.
Product Advantages: Broad-spectrum control, ZIMECTERIN Paste kills important internal parasites, including bots and the arterial stages of Strongyles vulgaris, with a single dose. ZIMECTERIN Paste is a potent anti-parasitic agent that is neither a benzimidazole nor an organophosphate.

Precautions: Ivermectin and excreted ivermectin residues may adversely affect aquatic organisms. Do not contaminate ground or surface water. Dispose of the ZIMECTERIN (ivermectin) Paste syringe in an approved landfill or by incineration.

Cautions: ZIMECTERIN (ivermectin) Paste has been formulated specifically for use in horses only. This product should not be used in other animal species as severe reactions, including fatalities in dogs, may result.
Note to User: Swelling and itching reactions after treatment with ZIMECTERIN Paste have occurred in horses carrying heavy infections of neck threadworm (Onchocerca sp) microfiliariae. These reactions were most likely the result of microfiliarae dying in large numbers. Symptomatic treatment may be advisable. Consult your veterinarian should any such reactions occur. Healing of summer sores involving extensive tissue changes may require other appropriate therapy in conjunction with treatment with ZIMECTERIN (ivermectin) Paste. Reinfection, and measures for its prevention, should also be considered. Consult your veterinarian if the condition does not improve.
