Outpatient KEYTRUDA Infusion Treatment Across the Southeast
When an oncologist recommends KEYTRUDA (pembrolizumab) by IV, patients and caregivers usually want to know what the visit looks like before it starts. TwelveStone coordinates KEYTRUDA infusion treatment in a calm outpatient setting, working with your referring oncology team from referral through each appointment.
KEYTRUDA can be given more than one way. This page covers the IV infusion route. Your oncologist decides whether KEYTRUDA fits your care plan and which route is prescribed.
How KEYTRUDA Works and Who Decides If It Fits
KEYTRUDA is the brand name for pembrolizumab, an immune checkpoint inhibitor. Your T cells carry a protein called PD-1 that acts like a brake. When PD-1 connects with PD-L1 or PD-L2, the T cells hold back, and some cancers use that signal to avoid attack. Pembrolizumab blocks PD-1, which helps your immune system recognize and respond to cancer cells.
KEYTRUDA has approved uses across many cancer types, alone or with other treatments. Your oncologist decides whether it is appropriate based on your diagnosis, biomarker testing when relevant, prior treatment, and full treatment plan. We do not prescribe it or change your plan.
Before Your KEYTRUDA Infusion: Coordination and Preparation
Coordination begins before your first appointment. We work with your referring oncology team to confirm the prescription, schedule, clinical details, and authorization requirements before scheduling your infusion treatment.
Our team verifies insurance benefits and reviews prior authorization needs that can affect scheduling or out-of-pocket cost. We can also point you to manufacturer copay assistance and foundation support programs when they apply. Coverage cannot be guaranteed.
Follow your oncology team’s instructions first. In general, these steps help you arrive ready:
What to Expect During Your KEYTRUDA Infusion Visit

Your visit begins with check-in, vital signs, a symptom review, and any lab work your oncologist requires. A nurse then places a peripheral IV or accesses your port while our pharmacy prepares your medication.
A KEYTRUDA immunotherapy infusion runs through an IV pump, generally over about 30 minutes. Your full appointment can be longer because of check-in, lab review, medication preparation, IV access, and discharge instructions. Before you leave, the team reviews your next steps.
We provide oncology infusion treatment in an outpatient setting with trained infusion nurses, pharmacist oversight, private suites, recliners, Wi-Fi, television, and refreshments. Your caregiver can stay with you in a guest chair.
Monitoring During KEYTRUDA Infusion Treatment
Infusion reactions can happen, but they are uncommon. Nurses watch for chills, itching, flushing, rash, fever, wheezing, dizziness, or trouble breathing during the dose and shortly after it.
Tell your nurse right away if you feel different, lightheaded, short of breath, or unwell. The team follows your oncologist’s orders and our reaction protocol. That may mean slowing or pausing the infusion and contacting your oncology team.
Premedication is not routine for every patient. Your oncology team decides whether you need it based on your treatment history and plan.
Immune-Related Side Effects to Report to Your Oncology Team
Pembrolizumab changes how your immune system behaves, so it can sometimes affect healthy tissue. These effects can appear days, weeks, or months after a dose, and sometimes after treatment ends. They differ from an infusion reaction, which starts during or soon after the dose.
Contact your oncology team promptly if you notice any of these:
Many causes can produce these symptoms, so your oncology team needs to assess them. Do not wait for your next infusion, and do not start new medicines on your own. If symptoms are severe, seek emergency care. Caregivers can help by keeping oncology contact numbers and a current medication list close at hand between visits.
How We Coordinate Outpatient Care With Your Oncology Team
We provide outpatient infusion care for patients with a valid oncology referral and a prescribed treatment plan. Our role is to carry out your oncologist’s direction, not to replace your oncology practice.
We coordinate scheduling, clarify orders when needed, document each treatment, and keep your oncology team informed about important concerns. That communication keeps your plan connected between visits.
Outpatient care is not right for every patient or regimen. Your condition, medication, and oncology plan determine whether hospital-based treatment is needed.
With more than 35 years in community healthcare, we serve patients across Alabama, Georgia, Indiana, Kentucky, Mississippi, South Carolina, Tennessee, and Virginia. Providers can submit a referral to confirm a nearby location and medication availability.
