Can You Take Your Regular Medicines During Immunotherapy — What Continues and What Needs a Check First
For most patients, yes — routine medicines for blood pressure, diabetes, thyroid conditions and cholesterol continue unchanged through immunotherapy. A small number of categories, particularly steroids, other immunosuppressant medicines and antibiotics, can affect how checkpoint inhibitor immunotherapy works and need your oncology team's sign-off before you start or stop them.

- Most medicines continue — Routine treatment for blood pressure, diabetes, thyroid and cholesterol usually carries on unchanged during immunotherapy.
- Steroids & immunosuppressants need review — These can blunt how well checkpoint inhibitor immunotherapy works and are reviewed case-by-case by your oncology team.
- Antibiotics deserve a heads-up — Research has linked recent antibiotic use to weaker immunotherapy responses in some cancers, so tell your team before starting one.
- Never decide alone — Herbal supplements, Ayurvedic remedies and even common painkillers should be flagged at your next review, not decided on your own.

Do Your Routine Medicines Continue During Immunotherapy?
Yes — for most patients, routine medicines for blood pressure, diabetes, thyroid conditions and cholesterol continue unchanged throughout immunotherapy. Checkpoint inhibitor immunotherapy does not automatically interact with most everyday medicines. What matters is that your oncology team has a complete, current list of everything you take, so anything that could interfere is caught early, not missed.
That doesn't mean every medicine is automatically fine to add or continue without a mention. A small number of categories — covered below — genuinely change how immunotherapy works, and the only way your team can catch them is if you tell them what you're taking, including things that don't feel medical, like a herbal supplement or a short course of antibiotics for a cold.
Call your oncology team or the CION helpline before taking anything else if you have:
- Signs of infection — fever, chills, or a new wound that isn't healing
- Sudden, severe or bloody diarrhoea
- Unexplained bruising, bleeding, or breathlessness
- Any new or severe symptom that started soon after you began, stopped or changed a medicine
Look closer at these
Which Medicine Categories Concern Your Immunotherapy Team?
Three categories get the closest attention: steroids and other immunosuppressant medicines, which can blunt how well immunotherapy works; antibiotics, which research has linked to weaker responses in some cancers; and blood-thinning or anti-inflammatory painkillers, which matter around procedures. Herbal and over-the-counter supplements need disclosure too, even though their individual risk is lower — and routine chronic-disease medicines almost always just continue.
Needs oncology sign-off
Steroids & Other Immunosuppressant Medicines
Medicines that calm immune activity — used for autoimmune disease, transplant care, or another condition — can blunt how well checkpoint inhibitor immunotherapy works and need case-by-case review before you start or continue them.
Tell your team first
Antibiotics
Even a short antibiotic course for an unrelated infection has been linked in research to weaker immunotherapy response in some cancers. Mention any antibiotic prescription to your oncology team before starting it.
Matters around procedures
Blood Thinners & Anti-Inflammatory Painkillers
These become most relevant before biopsies, dental work or any procedure, and if you develop an immune-related side effect being treated with steroids. Flag them at your next review.
Disclose, don't hide
Herbal, Ayurvedic & Over-the-Counter Supplements
Individually lower-risk, but interactions are rarely well studied. Tell your team what you take so nothing is missed — disclosure, not permission-seeking, is the goal.
Usually just continue
Routine Chronic-Disease Medicines
Blood pressure, diabetes, thyroid and cholesterol medicines usually carry on unchanged. Still list them at every review, since doses occasionally need adjusting once other medicines are added.
Timing
When Does Each Medicine Category Typically Need a Second Look?
A general guide, not a checklist to self-manage from — your oncology team makes the actual call for your specific medicines.
| Category | When it typically comes up | Why it matters | What usually happens next |
|---|---|---|---|
| Steroids & other immunosuppressants | Before starting immunotherapy, or if prescribed later for another condition | Can blunt how well checkpoint inhibitor immunotherapy works | Oncology team reviews the specific medicine and reason before deciding |
| Antibiotics | Any time, especially around your immunotherapy infusions | Linked to weaker immunotherapy responses in some published research | Team is told before or as soon as a course starts |
| Blood thinners & anti-inflammatory painkillers | Around biopsies, dental work, procedures, or during an immune-related side effect | Bleeding and healing risk changes when combined with certain treatments | Timing is coordinated with your procedure or side-effect treatment plan |
| Herbal, Ayurvedic & OTC supplements | Whenever you start a new one, however minor it seems | Interactions are rarely well documented | Disclosed at your next review; rarely needs stopping outright |
| Routine chronic-disease medicines | At every immunotherapy review | Usually unaffected, but doses can need adjusting once other medicines are added | Continue as prescribed unless your team says otherwise |
Did you know?
A growing body of oncology research, including studies discussed at forums such as ASCO, has linked recent antibiotic use to weaker responses to checkpoint inhibitor immunotherapy in several cancers — likely because antibiotics disrupt gut bacteria that appear to support a healthy immune response. It is one reason your oncology team wants to know about every antibiotic course, however minor it seems.
The final call
Who Decides Whether a Medicine Needs to Pause?
Your medical oncology team decides — not a pharmacist's general advice, a family member's experience, or something read online. The decision depends on your specific cancer, the medicine involved, why you need it, and how your immunotherapy is progressing, coordinated directly with any other specialist managing a separate condition.
This matters most if you already live with an autoimmune disease or have had an organ transplant and take immunosuppressant medicines for that reason. In that situation, your medical oncologist and the specialist managing your other condition — a rheumatologist, nephrologist, or transplant physician — need to plan your care together, since the same medicine that protects a transplanted organ or controls an autoimmune disease can also be the one immunotherapy needs adjusted. Neither doctor should be making that call without knowing what the other has prescribed.

Want to Know Exactly Which of Your Medicines Need a Second Look?
A medical oncologist can review your full medicine list against your specific treatment plan — free, confidential, and with no commitment to start treatment.
Understanding the mechanism
Why Does Immunotherapy Make Ordinary Medicines Worth a Second Look?
Checkpoint inhibitor immunotherapy works by releasing brakes the immune system normally uses to hold back, letting your own T-cells recognise and act against cancer cells. Anything that suppresses or otherwise modulates immune activity — steroids taken for an unrelated condition, immunosuppressants for autoimmune disease or transplant care — can work against that mechanism, which is why they get flagged rather than continued by default.
Antibiotics matter for a different reason. Gut bacteria appear to play a supporting role in how well the immune system responds to checkpoint inhibitor immunotherapy, and antibiotics disrupt that bacterial population. Blood thinners and anti-inflammatory painkillers matter for a third, more mechanical reason — bleeding and healing risk changes around biopsies, dental work and any procedure, and if you're already being treated with steroids for an immune-related side effect, adding certain painkillers can complicate that treatment further. NCCN and ASCO guidance on managing immunotherapy both call for a full medicine review before treatment starts, precisely because these mechanisms don't announce themselves the way a drug interaction leaflet usually does.
A practical routine
What Should You Do Before You Start Any New Medicine During Immunotherapy?
1
Keep one complete, current medicine list
Include prescriptions, over-the-counter medicines, and any herbal or Ayurvedic supplements — not just the ones that feel medical. Update it after every change, not just before appointments.
2
Tell your oncology team before starting, not after
This applies to any new prescription, over-the-counter medicine, or supplement — don't wait for your next scheduled review if the new medicine can't wait either.
3
Make sure your other specialists are talking to each other
If a rheumatologist, transplant physician or other specialist also manages a separate condition, ask that they and your oncology team coordinate directly rather than relaying instructions through you.
4
Never stop a medicine on your own to "protect" your immunotherapy
Stopping a medicine you actually need — for example a transplant anti-rejection medicine — can be more dangerous than the theoretical interaction you're trying to avoid. Let your team weigh that trade-off.

Common questions
Can You Take Your Regular Medicines During Immunotherapy? — Your Questions Answered
Can I keep taking my regular blood pressure, diabetes, thyroid or cholesterol medicines during immunotherapy?
Yes, in most cases. Immunotherapy does not automatically interact with the everyday medicines used to manage blood pressure, diabetes, thyroid conditions or cholesterol, and these usually continue exactly as your regular doctor has prescribed them. What does change is that your oncology team needs a complete, current list of everything you take, because side-effect treatments added later — such as steroids for an immune reaction — can sometimes need existing doses reviewed. Bring your full medicine list, including any recent changes, to every immunotherapy review rather than assuming nothing needs to be said.
Which medicine categories concern your immunotherapy team the most?
Three categories get the closest attention: steroids and other immunosuppressant medicines, because they can blunt how well checkpoint inhibitor immunotherapy works; antibiotics, because research has linked recent antibiotic courses to weaker immunotherapy responses in some cancers; and blood-thinning or anti-inflammatory painkillers, which matter most around biopsies, dental work or any procedure. Herbal, Ayurvedic and over-the-counter supplements are lower-risk individually but still need disclosure, since their interactions are rarely well documented. None of this means these medicines are forbidden — it means your oncology team wants to know before you start or stop any of them.
Why do steroids and other immunosuppressant medicines matter so much during immunotherapy?
Checkpoint inhibitor immunotherapy works by releasing the brakes on your own immune system so it can act against cancer cells. Steroids and other immunosuppressant medicines work in the opposite direction — calming immune activity — so taking them for an unrelated condition can, in some situations, reduce how well immunotherapy is able to work. This matters most for patients already on long-term immunosuppression for an autoimmune disease or after an organ transplant. It does not automatically rule immunotherapy out, but it does mean your oncologist and the specialist managing that other condition need to plan your care together.
Can antibiotics affect how well immunotherapy works?
Possibly, yes. A growing body of oncology research, discussed at forums including ASCO, has linked recent antibiotic use to weaker responses to checkpoint inhibitor immunotherapy in several cancers, likely because antibiotics disrupt gut bacteria that appear to support a healthy immune response. This does not mean antibiotics are off-limits — genuine infections still need treating — but it is a reason to tell your oncology team before starting any antibiotic course, however minor it seems, rather than mentioning it only at your next scheduled visit.
Who decides whether a medicine needs to pause during immunotherapy?
Your medical oncology team makes that call, never a pharmacist's general advice, a family member's experience, or something read online. The decision depends on your specific cancer, the medicine involved, why you need it, and how your immunotherapy is progressing. If you also see a rheumatologist, transplant physician or another specialist for a separate condition, your oncology team will usually coordinate directly with them rather than asking you to relay instructions between two doctors who haven't spoken to each other.
What if I take Ayurvedic, homeopathic or herbal supplements alongside immunotherapy?
Tell your oncology team about them, plainly and without worrying about being judged. Many patients use traditional or herbal remedies alongside cancer treatment, and the goal is disclosure, not giving them up on your doctor's say-so alone. Some herbal products can affect the liver or interact with medicines in ways that are poorly studied, which is exactly why your team needs to know what you are taking. Being open about it helps your care team keep every part of your treatment safe, without dismissing what matters to you.
