Further Information about Cimalgex

Cimalgex is manufactured by Vetoquinol and contains the active ingredient cimicoxib. Cimicoxib is a non steroidal anti inflammatory drug so Cimalgex is used as pain relief both short term for pain and inflammation associated with surgical procedures and also long term to control the pain and inflammation of osteoarthritis.

The active ingredient in Cimalgex, cimicoxib, is a selective COX-2 inhibitor. This means that it blocks the pathways that result in the formation of inflammatory mediators which reduces inflammation and pain. The advantage of Cimalgex over older non steroidal drugs is that they are COX-2 selective. Some older non steroidals also block the COX-1 pathway and this actually forms compounds that are protective to the gut and kidneys and it is this that causes the main side effect of these drugs so COX-2 selective non steroidal drugs have fewer side effects.

Cimalgex can have some side effects although these are usually mild and temporary. The main side effects that can be seen are vomiting and diarrhoea and more rarely anorexia and lethargy. If persistent vomiting and diarrhoea or weight loss are seen then stop the medication and contact your vet for advice. Cimalgex should be used with care in animals under 6 months old or animals who are dehydrated or suffer from pre existing kidney, liver or heart disease. Cimalgex should be avoided in animals under 10 weeks old, animals that are pregnant or lactating and animals already taking steroids or other non steroidal drugs at the same time.

Further Information about Dosage and Administration

Cimalgex is given as an oblong, white/brown, chewable tablet, once daily. Cimalgex can be given with or without food. Cimalgex tablets are flavoured and are scored so they can be divided for ease of administration. Half tablets, when broken, can be stored for up to two days before they need to be discarded. Cimalgex come as three sized tablets, 8mg, 30mg and 80mg tablets. These come in blister packs of either 8, 32 or 144 tablets or in a bottle of 45 tablets.

When Cimalgex is being used to control pain associated with surgical procedures, a dose is usually given 2 hours prior to the surgery and then for 3-7 days post surgery. If Cimalgex is being used in cases of osteoarthritis then it is usually used for 6 months and then if the desired pain relief is not being achieved it is stopped. If it is controlling the pain and inflammation of arthritis then Cimalgex can be used for longer than 6 months but at this stage, regular monitoring of the kidneys and liver is advised.
