Which Samylin should I choose?
Choose by species and bodyweight first, then pick tablets or sachets.
| Option | Suitable for | Pack label | Daily amount (VetPlus guide) |
|---|---|---|---|
| Small Breed (tablets or sachets) | Cats and small dogs | Under 10 kg | Under 5 kg: 1 a day 5 to 10 kg: 2 a day |
| Medium Breed (tablets or sachets) | Dogs only | 10 to 30 kg | 11 to 20 kg: 1 a day 21 to 30 kg: 2 a day |
| Large Breed (tablets or sachets) | Dogs only | Over 30 kg | 31 to 40 kg: 2 a day 41 to 50 kg: 3 a day |
VetPlus’s daily-amount guide covers pets up to 50 kg and does not list weights between 10 and 11 kg or between 30 and 31 kg. For dogs over 50 kg, or a pet near the edge of a weight band, ask your vet which size and amount to use.
Tablets or sachets?
- Tablets are coated and should be given whole. They have no added flavouring because they are designed to be given whole.
- Sachets contain a palatable powder with poultry flavouring. Mix the contents into your pet’s food. Sachets are mixed into food, which suits pets that will not take a tablet.
How long does a pack of 30 last?
A pet on 1 a day uses a pack in 30 days, on 2 a day in 15 days, and on 3 a day in 10 days.
How to give Samylin
Samylin Liver Support for Dogs and Cats is simple to give at home:
- Give with or without food.
- Give tablets whole. Mix sachet contents into food.
- Samylin can be used to support the liver in the short or long term.
- Follow your vet’s advice if it differs from the guide above.
When to speak to your vet
There are many causes of liver problems, and care may involve diet changes, medicines and other support from your vet. VetPlus describes Samylin as a complementary feed, and it does not claim to treat liver disease. Contact your vet if your pet shows:
- vomiting or diarrhoea
- lethargy
- weight loss
- yellowing of the skin or the whites of the eyes
- any other change that worries you
