Custom pet medication, compounded in Kuala Lumpur

If your vet has prescribed a medicine your cat won’t take, your dog reacts to, or your rabbit can’t have because of its size, Lynnity can almost certainly compound an alternative. We work directly with Malaysian veterinarians to reformulate medicines for cats, dogs, rabbits, ferrets, guinea pigs, birds, and reptiles.

Quick facts

  • Flavour bases for pets: chicken, beef, fish, liver, tuna, peanut butter, malt, neutral.
  • Dose forms: flavoured oral suspension, treat-style chew, transdermal gel (cat ear), capsule, lozenge.
  • Common compounds: methimazole transdermal gel (feline hyperthyroidism), flavoured fluoxetine chews (canine behavioural), buprenorphine oral solution, potassium bromide for canine epilepsy.
  • Requires: prescription from a Malaysian-registered veterinarian.

Why pets need compounded medication

Three problems compounding solves for pets:

  1. They refuse the pill. Cats are masters of spitting out tablets. Compounding lets the vet prescribe the same drug as a chicken-flavoured liquid or a transdermal gel applied to the ear flap.
  2. The dose is wrong for the species. A 5 kg cat needs roughly 10% of a 50 kg dog’s dose. Splitting a tablet to that accuracy isn’t possible — a 0.5 mg/mL suspension is.
  3. Commercial products contain species-toxic ingredients. Xylitol (in many human sugar-free products) is fatal to dogs; paracetamol is fatal to cats; certain flavourings irritate exotic species. A compounded version removes these.

Species-specific safety notes

Our pharmacists screen every prescription against the following non-exhaustive list before compounding:

  • Cats: no acetaminophen, no aspirin > 81 mg/kg q72h, no propylene glycol in chronic doses, no benzoyl peroxide topically.
  • Dogs: no xylitol, no chocolate, no grape, no macadamia, no caffeine, no alcohol in flavour bases.
  • Rabbits / guinea pigs: no oral penicillin, no clindamycin orally (enterotoxaemia risk).
  • Birds: species-appropriate volume only; no ethanol-based liquids.
  • Reptiles: preservative-free preparations only where the dose volume exceeds 5% body weight.

How a vet sends a prescription

Veterinarians send the prescription to eugene@lynnitypharma.com or WhatsApp +60 12-661 8987 with:

  • Patient species, breed, weight, age.
  • Drug, strength, dose form requested, total quantity.
  • Flavour base preference (or “pharmacist’s choice”).
  • Owner’s name and contact for dispense / collection.

We confirm receipt within 4 working hours and compound within 3–5 working days. Urgent post-surgical analgesia can sometimes be expedited.

Frequently asked questions

What types of veterinary medicines does Lynnity compound?

Lynnity compounds analgesics (for arthritis and post-surgical pain), dermatology preparations (otic drops, antifungal creams), behavioural medications (fluoxetine, gabapentin), hormone therapy (methimazole for feline hyperthyroidism), and joint-health formulations for cats, dogs, rabbits, ferrets, and exotic pets.

What flavours are available for pet medications?

Lynnity uses chicken, beef, fish, liver, peanut-butter, malt, and tuna flavour bases for cats and dogs. For exotic pets, neutral or species-appropriate bases are used (e.g., fruit flavours for some birds). Flavour selection improves compliance — animals are much more likely to take a flavoured liquid or treat-style chew.

Does my veterinarian need to send the prescription?

Yes. Veterinary compounds require a prescription from a registered Malaysian veterinarian. Lynnity works directly with the prescribing vet to confirm species-appropriate dose, excipients (some sweeteners like xylitol are toxic to dogs), and dosage form.

How long do pet medications take to prepare?

Most veterinary compounds are ready in 3 to 5 working days. Urgent post-surgical pain compounds can sometimes be expedited — call +60 12-661 8987 to confirm.

Can I get methimazole as a transdermal ear gel for my cat?

Yes. Compounded methimazole 2.5% – 5% in a pluronic lecithin organogel (PLO) is one of our most frequently dispensed veterinary compounds. Owners apply 0.05 mL to the inner pinna of the cat’s ear twice daily, alternating ears. Bypasses the oral route entirely.

My pet won’t take any flavour — what now?

For oral-refusing pets we can usually compound a transdermal alternative (works for some drugs, not all) or a treat-style chew with high palatability rates. Speak to your vet about whether the drug is suitable for transdermal delivery.
