Keytruda

Keytruda (Pembrolizumab) is a new treatment for treating a particular form of lung cancer known as non-small cell lung cancer and for a type of skin cancer called melanoma.

Keytruda (Pembrolizumab) can be used to treat lung cancer when:

• the cancer has spread AND;
• it tests positive for PD-L1 AND;
• when chemotherapy containing platinum has not worked AND;
• if the tumor has "EGFR" or "ALK" gene and you have tried an EGFR or ALK inhibitor medicine

Keytruda (Pembrolizumab) can be used to treat melanoma when:

• the melanoma has spread and cannot be surgically removed AND;
• treatment with ipilimumab has not been successful AND;
• if the tumor has an abnormal "BRAF" gene and you have tried a BRAF inhibitor medicine

Keytruda is usually prescribed at a dosage of 2mg/kg. This is administered by intravenous infusion over a period of thirty minutes. This should be repeated every three weeks until your doctor notices an improvement in the disease, or the levels in the body become too toxic.

The most common side effects of Keytruda (Pembrolizumab) are tiredness, coughing, nausea, itchiness, rash, shortness of breath, reduce appetite, constipation or diarrhea, and joint pain.

More serious side effects can occur if the immune systems begins attacking other organs. Tell your doctor if you notice:

• chest pain
• frequent bowel movements
• stools that are black, tarry, sticky, or have blood or mucus
• stomach pain or tenderness
• yellowing of the skin or whites of the eyes (jaundice)
• bleeding or bruising more easily that usual
• rapid or erratic heartbeat
• weight loss or weight gain
• increased sweat rate
• increased thirst
• frequent urination
• change in urine color
• changes or problems with eyesight
• severe or persistent muscle or joint pain
• signs of fever (chills, shaking, dizziness)

Keytruda works alongside your immune system to fight cancer. Sometimes the immune system can attack healthy organs and tissues and cause them to function incorrectly. This can lead to lung problems, intestinal problems, liver problems, kidney problems, hormone gland problems or problems to other organs.

Before starting treatment with Keytruda, be sure your doctor is aware of any immune system problems you have including Crohn`s disease, ulcerative colitis or lupus.

If you have had an organ transplant, make sure your doctor knows this.

Keytruda (Pembrolizumab) can harm an unborn baby. Make sure to be using contraception when taking Keytruda. It is not known if Keytruda is passed from a nursing mother through breast milk.
