Do Pembrolizumab injections need to be given before chemotherapy?

Pembrolizumab is a cancer treatment given through a vein. This is called an infusion. The doctor will inject pembrolizumab into your vein through an intravenous (IV) line. Treatments take more than 30 minutes. They can be done at your doctor or an infusion clinic, but must be supervised by a doctor or health care provider. In the absence of meals or low calcium(≤50 mg) with a meal, take pembrolizumab at least 2 hours before or after taking other medications (such as antacids), calcium-rich foods (containing >50 mg of calcium, such as dairy products, calcium-fortified juices, and certain fruits and vegetables), or supplements containing polyvalent cations (such as iron, calcium, aluminum, magnesium, selenium, and zinc).

For some patients with cancer, pembrolizumab may be used as a stand-alone treatment without the need for concurrent chemotherapy. In this case, the injections can be given before, after, or independently of chemotherapy. Pembrolizumab may be used in combination with chemotherapy. In this case, pembrolizumab is often injected before chemotherapy to increase the effectiveness of the treatment. Chemotherapy can help reduce tumor burden, making it easier for pembrolizumab to work.
