1. WHAT METHOTREXATE 2.5MG TABLETS ARE AND WHAT THEY ARE USED FOR

Methotrexate 2.5mg Tablets are one of a group of medicines called antimetabolites which affect cell growth, including the growth of cancer cells.

Methotrexate can be used to treat severe cases of psoriasis (a skin disease) and rheumatoid arthritis (a disease of the joints). It is usually used for patients who have tried other treatments but their illness has not improved. It helps patients with psoriasis by killing the cells in the skin which are growing too quickly. It is these fast growing cells which cause the raised patches of skin in psoriasis. In the treatment of rheumatoid arthritis, methotrexate is thought to stop or reduce inflammation in the joints by altering the body's defence mechanisms in the immune system.

Methotrexate can also be used to treat several kinds of cancer when it can be given alone or in combination with other medicines. It is usually used in much higher doses when it is used to treat cancer and it will often be given as an injection rather than tablets.
