Keytruda 100mg Injection (Pembrolizumab) – Uses, Side Effects, Dosage & Price in Pakistan

Keytruda 100mg Injection (Pembrolizumab) is a prescription immunotherapy medicine used to treat several types of cancer. It contains pembrolizumab, a monoclonal antibody that belongs to a group of cancer treatments known as PD-1 immune checkpoint inhibitors.

Unlike conventional chemotherapy, pembrolizumab helps the body’s immune system recognize and attack certain cancer cells. Keytruda may be prescribed alone or together with chemotherapy, targeted medicines or other cancer treatments depending on the type and stage of cancer.

Keytruda is given as an intravenous (IV) infusion under medical supervision. It is not intended for self-administration at home.

Patients searching for Keytruda 100mg Injection price in Pakistan should remember that imported oncology medicine prices can change because of supply, manufacturer availability and market conditions. Patients can contact Impo Medic for current product and availability information in Pakistan.

Keytruda 100mg Injection (Pembrolizumab) Used

Pembrolizumab has approved uses across a wide range of cancers. Whether Keytruda is appropriate depends on the cancer type, stage, previous treatments and, for some indications, specific biomarkers.

Depending on the clinical situation, Keytruda may be used for certain cases of:

• Non-small cell lung cancer
• Small cell lung cancer
• Melanoma
• Head and neck squamous cell cancer
• Classical Hodgkin lymphoma
• Primary mediastinal large B-cell lymphoma
• Urothelial cancer
• Colorectal cancer
• Gastric and gastroesophageal junction cancer
• Esophageal cancer
• Cervical cancer
• Endometrial cancer
• Renal cell carcinoma
• Triple-negative breast cancer
• Hepatocellular carcinoma
• Biliary tract cancer
• Merkel cell carcinoma
• Cutaneous squamous cell carcinoma

Pembrolizumab also has indications involving cancers with certain biomarkers, including MSI-H, dMMR or high tumor mutational burden (TMB-H) in specified treatment settings.

The exact approved indication, combination therapy and biomarker requirements vary. Therefore, Keytruda should only be selected by an experienced oncology team.

How Does Keytruda 100mg Injection Work?

Cancer cells can sometimes use the PD-1 pathway to reduce the immune system’s ability to recognize and attack them.

Pembrolizumab is an antibody that binds to the PD-1 receptor on immune cells. By blocking interactions between PD-1 and its ligands, including PD-L1 and PD-L2, pembrolizumab can restore immune activity against susceptible tumor cells.

This is why Keytruda is called an immune checkpoint inhibitor.

Because it activates immune responses, some Keytruda side effects are different from those associated with conventional chemotherapy. The immune system can sometimes attack healthy organs and tissues, causing immune-mediated adverse reactions.

Keytruda 100mg Injection Dosage

Keytruda 100mg Injection refers to the product concentration/amount supplied in the vial and should not be interpreted as the standard patient dose.

Pembrolizumab dosing varies according to:

• Patient age
• Cancer type
• Treatment setting
• Combination therapy
• Treatment response
• Side effects
• Pediatric or adult use

For many adult indications, established regimens include 200mg every 3 weeks or 400mg every 6 weeks, but the correct regimen depends on the approved indication and treating oncologist’s plan.

Pediatric dosing can be weight-based for appropriate indications.

Patients must never calculate or modify a Keytruda dose themselves.

How Is Keytruda Administered?

Keytruda is administered by intravenous infusion, generally over approximately 30 minutes, by trained healthcare professionals.

Before each treatment, the oncology team may review:

• Current symptoms
• Blood counts
• Liver function
• Kidney function
• Thyroid function
• Other hormone levels when indicated
• Previous treatment reactions

Treatment may be temporarily withheld or permanently discontinued if serious immune-related or other adverse reactions occur.

Keytruda should not be injected or infused by the patient at home unless a healthcare system specifically provides an appropriately supervised administration program.

Common Side Effects of Keytruda

Side effects vary depending on whether pembrolizumab is used alone or with other cancer treatments.

Commonly reported effects can include:

• Fatigue
• Reduced appetite
• Nausea
• Diarrhea
• Constipation
• Rash
• Itching
• Muscle or joint pain
• Cough
• Shortness of breath
• Fever

Combination treatment may cause additional side effects associated with chemotherapy or other medicines used alongside Keytruda.

Patients should report new or worsening symptoms to their oncology team rather than waiting for the next scheduled appointment.

Serious Immune-Mediated Side Effects

One of the most important considerations with Keytruda 100mg Injection (Pembrolizumab) is the possibility of immune-mediated adverse reactions.

These reactions can affect almost any organ and can occur during treatment or after treatment has ended.

Lung Problems

Immune-mediated pneumonitis can cause inflammation of the lungs.

Symptoms may include:

• New or worsening cough
• Chest discomfort
• Difficulty breathing
• Shortness of breath

These symptoms require prompt medical assessment.

Intestinal Problems

Pembrolizumab can cause immune-mediated colitis.

Warning signs include:

• Persistent diarrhea
• Blood or mucus in stools
• Severe abdominal pain
• Significant changes in bowel habits

Severe diarrhea should not simply be treated at home without contacting the oncology team.

Liver Problems

Immune-mediated hepatitis may occur.

Patients should promptly report symptoms such as:

• Yellowing of the skin or eyes
• Dark urine
• Severe nausea or vomiting
• Pain on the right side of the abdomen
• Unusual tiredness

Liver blood tests are generally monitored during therapy.

Hormone Gland Problems

Keytruda can affect endocrine glands, including the:

• Thyroid
• Pituitary gland
• Adrenal glands
• Pancreas

This may result in thyroid disorders, adrenal insufficiency, hypophysitis or type 1 diabetes.

Symptoms such as severe weakness, persistent headache, dizziness, unusual thirst, frequent urination or unexplained weight changes should be discussed with the healthcare team.

Kidney Problems

Immune-mediated nephritis can affect kidney function.

Doctors may monitor kidney blood tests during treatment and investigate unexplained changes.

Skin Reactions

Serious immune-related skin reactions can occur, although they are less common.

Blistering, peeling skin, widespread rash or sores involving the mouth or other mucous membranes require urgent medical assessment.

Infusion-Related Reactions

Some patients can experience a reaction during or after the Keytruda infusion.

Possible symptoms include:

• Chills
• Fever
• Flushing
• Itching
• Rash
• Dizziness
• Wheezing
• Shortness of breath

Healthcare professionals monitor patients during administration and can slow, stop or permanently discontinue treatment depending on the severity of the reaction.

Monitoring During Keytruda Treatment

Regular medical follow-up is essential throughout pembrolizumab therapy.

Monitoring may include:

• Liver-function tests
• Kidney-function tests
• Thyroid-function tests
• Blood glucose when appropriate
• Assessment for respiratory symptoms
• Assessment for gastrointestinal symptoms
• Imaging to evaluate cancer response
• Other laboratory tests based on symptoms and treatment combinations

Immune-mediated reactions can sometimes begin after treatment has been discontinued, so new symptoms should still be reported to the oncology team.

Drug Interactions and Other Medicines

Patients should provide their oncologist with a complete list of medicines they use, including:

• Prescription medicines
• Over-the-counter medicines
• Vitamins
• Herbal products
• Supplements

Patients should not start medicines intended to suppress or stimulate the immune system without consulting their cancer specialist.

Treatment decisions involving corticosteroids or other immunosuppressive medicines should be managed by healthcare professionals, particularly when treating immune-mediated adverse reactions.

Pregnancy and Breastfeeding

Pembrolizumab may cause harm to an unborn baby.

Patients who can become pregnant should discuss effective contraception with their healthcare professional during treatment and for the recommended period after their final dose.

Breastfeeding is generally not recommended during treatment and for the specified period following the last dose.

Patients who are pregnant, planning pregnancy or breastfeeding should inform their oncology team before receiving Keytruda.
