Tilmicosin (Micotil)
Pet owner information sheet
💊 The most important rule: give this medication exactly as your veterinarian prescribed it — the right dose, at the right times, for the right number of days.
What is this medication for?
- BRD/pneumonic pasteurellosis (Mannheimia/Pasteurella)
- Medicated FEED only (Pulmotil) — injection FATAL in swine
How is it given?
Give exactly as your veterinarian prescribed — never change the dose or stop on your own unless your veterinarian has told you to.
What if I miss a dose?
- Give it as soon as you remember — unless it is almost time for the next dose (then skip the missed one; never double up).
- Call your clinic if you miss more than one dose in a row.
Side effects — what should I watch for?
Effects listed as common in this handout
- None commonly reported; call your clinic with any concern.
Worth a phone call to your veterinarian
- Any new symptom that worries you.
⚠️ Contact your veterinarian or an emergency clinic IMMEDIATELY if you notice
- into a muscle/under the skin tissue reactions, edema, tissue death (trim loss) (Route-related)
- Fatal cardiovascular toxicity (into a vein, overdose, wrong species) (The defining risk)
Before starting (or refilling), tell your veterinarian if your pet:
- has or has had: into a vein, powered syringes, swine injection, camelids (question-marked), horses (potentially fatal)
- has or has had: Human-exposure emergency protocol; avoid eyes
- is pregnant, nursing, or used for breeding
- is taking any other medications, supplements, or flea/tick products, including:
- Epinephrine
- Erythromycin-class interactions
Storage and handling
NEVER in automatically powered syringes (auto-injector = accidental human injection machine); never into a vein; avoid eye contact; HUMAN EXPOSURE → PHYSICIAN IMMEDIATELY + manufacturer emergency line (1-800-722-0987) — the most extreme handling protocol in the library |
Good to know
- The pharmacy-law star: Micotil's human-fatality profile (cardiovascular collapse from a needlestick-scale accident) drives the "no powered syringes + emergency number on the box" dispensing culture — Elanco's warning card exists because people died.
- Cattle every 3 days dosing = the long-tissue-persistence macrolide convenience, same logic as tulathromycin's single shot.
- Epinephrine + tilmicosin increased mortality in swine — one more "not everything resuscitates" entry alongside α2-TMPS.
