Celecoxib is a cancer treatment drug and is also known by its brand name, Celebrex.

Its a treatment sometimes used to try and prevent bowel cancer in people at high risk of developing it.

Clinical trials are looking at whether celecoxib can treat or prevent other types of cancer, including:

  • prostate cancer
  • breast cancer
  • bladder cancer

How it works

Celecoxib is one of a group of drugs called COX-2 inhibitors.

COX-2 inhibitors are a type of anti inflammatory drug. They block a protein called COX-2 that causes inflammation and pain. COX-2 inhibitors are used to control pain caused by some medical conditions such as arthritis.

There is some evidence that the enzyme COX-2 may also help cancers to grow.

Celecoxib is a capsule. You swallow it whole with a glass of water. You can take it with or without food.

Taking capsules

You must take tablets and capsules according to the instructions your doctor or pharmacist gives you.

You should take the right dose, not more or less.

Never stop taking a cancer drug without talking to your specialist first.

When you have it
