Recommended Dosage of Keytruda 100mg Injection

For adult patients with unresectable or metastatic melanoma, the recommended dosage is 200 mg every 3 weeks or 400 mg every 6 weeks until disease progression or unacceptable toxicity.

Warnings and Precautions of Keytruda Injection

Warnings:

Keytruda can lead to serious or even life-threatening side effects. We advise monitoring for side effects during the injection, as it may cause your immune system to mistakenly attack normal organs and tissues, affecting their function. Your healthcare provider will watch for these signs.
Severe reactions can happen during infusion. If you experience symptoms like chills, shaking, rashes, difficulty breathing, dizziness, fever, or back pain during the infusion, immediately inform your healthcare provider.

For those who have had a bone marrow transplant using donor stem cells, either before or after receiving Keytruda, there’s a risk of serious complications, including graft-versus-host disease (GVHD). Your healthcare provider will monitor you closely for these.
If you’ve had an organ transplant, Keytruda may cause the body to reject the transplanted organ. Be sure to discuss the signs and symptoms you need to report with your healthcare provider.

The use of Keytruda for conditions like multiple myeloma, in combination with certain other drugs, is not recommended outside of clinical trials.

Keytruda can harm an unborn baby. If you’re of reproductive potential, it’s crucial to use effective contraception.

Precautions:

To ensure Keytruda is safe for you, you should inform your doctor if you have had any autoimmune disorders (like rheumatoid arthritis, Crohn’s disease, lupus), a stem cell or organ transplant, chest radiation, or nerve-muscle disorders (like myasthenia gravis).
