POM-V (Prescription Required)
Pharmasin 1g/g Granules for Use in Drinking Water for Pigs, Chickens, Turkeys and Calves is a prescription-only antibiotic medicine (POM-V). It contains tylosin, a macrolide antimicrobial used to treat specific bacterial infections in these food-producing species.
The granules are added to drinking water or, for calves, to milk or milk replacer. This allows group treatment when a number of animals in a pen, shed or house require therapy.
Your vet will decide when Pharmasin is appropriate, based on diagnosis, farm history, sensitivity patterns and responsible use guidelines.
Species and uses
Pharmasin 1g/g Granules is licensed for:
Pigs – as directed by your vet for certain tylosin-sensitive infections
Chickens – for use in drinking water as part of a targeted treatment plan
Turkeys – for specified bacterial conditions where tylosin is indicated
Calves – via milk or milk replacer, when group treatment is required
Your vet will explain exactly why Pharmasin has been prescribed on your farm (for example, respiratory disease, enteric disease or other labelled indications), and will set an appropriate course length.
Pack sizes on this page
This product page lists two tub sizes as variations:
110g tub – suited to smaller groups or short courses

How Pharmasin 1g/g Granules works
Pharmasin 1g/g Granules contains tylosin, a macrolide antibiotic. Macrolides act mainly by:
Inhibiting bacterial protein synthesis
Helping stop growth of susceptible bacteria
Allowing the animal’s immune system to clear infection more effectively
Because Pharmasin is an antibiotic, responsible use is essential to help reduce the risk of antimicrobial resistance. It should only be used where clearly indicated and under veterinary control.
How Pharmasin 1g/g Granules is given
Always follow the written directions on your veterinary prescription and the product label. General points (not a substitute for your vet’s instructions):
The required dose is calculated from:
The prescribed mg tylosin per kg bodyweight
The average weight of animals in the group
The expected daily water or milk intake
Granules are carefully weighed or measured and dissolved in the drinking water system or milk/milk replacer for calves
Fresh medicated water/milk is usually prepared daily, or as your vet and datasheet advise
Ensure that treated animals have no access to unmedicated water during the dosing period, unless your vet has specified otherwise
Your vet or a suitably trained person should show you exactly how to calculate and prepare the medicated solution for your particular set-up.
If you are unsure at any point, contact your vet before continuing treatment.
Monitoring during treatment
While animals are receiving Pharmasin 1g/g Granules:
Check appetite, demeanour and faeces regularly
Observe water or milk intake closely – reduced intake may alter the dose actually received
Reassess group weight estimates if animals are growing rapidly
Contact your vet if:
There is no improvement
Signs worsen or new signs appear
You are concerned about any animal’s condition
Your vet may adjust the plan, extend or shorten the course, or change to another treatment depending on clinical response and lab results.
