Alimta is a medicine whose active ingredient is Pemetrexed. It is used in chemotherapy treatments to combat malignant pleural mesothelioma and non-small cell lung cancer. Alimta is one of the drugs called antimetabolites. Their job is to interfere with the growth and spread of cancer cells in the body.

Alimta comes as a solution for injection containing 500 mg pemetrexed, given intravenously; and must be administered in a health center by a medical professional. The dose to be supplied will depend on various factors: weight and height, type of cancer or other health problems that the patient presents. It is usually given every 3 weeks; the specialist will be the one who indicates the cycles of treatment that you should receive.

Generally, people who receive treatment with alimta should complement said treatment with vitamin B12 and folic acid supplements, in order to slightly reduce treatment-related side effects. Your doctor may ask you to have regular blood tests while you are taking alimta, as your doctor may use these blood tests to change your dose or delay your treatment.

You should not receive this medication if you are allergic to pemetrexed, much less if you are pregnant or nursing. Similarly, it is prohibited in patients who are taking non-steroidal anti-inflammatory drugs or if they have liver conditions or have a weak immune system.

Patients receiving medication with this drug should avoid contact with people who are sick or have infections, nor should they receive “live vaccines”. This medication can pass into body fluids (faeces, urine, vomit) for at least 48 hours after receiving the dose, so it is recommended that these fluids do not come into contact with your hands.

Among the most common side effects that occur during treatment are: weight loss, feeling tired, loss of appetite, hair loss, diarrhea, vomiting, upset stomach, rash, depression. Similarly, there are other much more serious reactions such as: difficulty breathing, swelling of the face, lips, or tongue, skin pain, signs of dehydration. It is important that the patient go to the doctor if he presents any of these discomforts.
