Fortekor Flavour Tablets 20mg

Fortekor Flavour Tablets 2.5mg, 5mg and 20mg are for the treatment of heart failure in dogs. The 2.5mg tablets can also be used in cats for the treatment of chronic kidney disease. They are a light brown, oval shaped flavoured tablet and are supplied either individually or in packs of 28. The 2.5mg tablets and 5mg tablets can also be purchased in packs of 56. The tablets are scored on both sides so they can be split to ensure accurate dosing.

Fortekor Tablets are a prescription item and will be sent once a valid prescription is received. Please follow the instructions given by your vet.

Heart failure occurs when the heart is unable to circulate enough blood to meet the metabolic demands of the body. Congestive heart failure can occur when the required mechanisms are over worked and this can then cause a volume overload of blood. When the fluids back up in the veins, it causes raised blood pressure and leakage can also occur. Fortekor helps to reduce the blood pressure and the volume load on the heart.

Fortekor should be given once daily and can be given with or without food. As they are flavoured tablets, most dogs will take the tablets voluntarily. The dosage rates are as follows:

5-10kg - 1/2 x 5mg tablet

10-20kg - 1 x 5mg tablet

20-40kg -  1/2 x 20mg tablet

40 - 80kg - 1 x 20mg tablet.

The dose may be doubled if specified by your Vet.

Do not use during pregnancy or lactation.
