Ototoxicity Monitoring Navigator

Some cancer treatments, powerful IV antibiotics, and other medicines can affect hearing and balance. This navigator helps you understand what basic hearing care to expect during treatment, and gives you clear language to use with your care team when you ask about baseline tests, monitoring, and follow-up.

About 2–4 minutes Designed for phones

This tool is for education, not diagnosis or treatment decisions. It cannot see your full medical picture. Do not stop or change any medicine on your own. If something feels like an emergency, or you notice sudden big changes in hearing, balance, or neurologic symptoms, treat it as urgent and seek care right away—even if this page suggests a non-urgent path.

Answer a few questions

This tool can’t tell how serious things are, but it can help you organize your thoughts about hearing tests during treatment. Choose the option that feels closest—even if it’s not perfect.

Question 1
Who are you filling this out for?

This only changes wording—it doesn’t change the medical message.

Question 2
Where are you in treatment or medicine use?

Think about the treatment your team has said could affect hearing—such as certain chemotherapy, IV antibiotics, or other long-term medicines.

Question 3
What hearing testing or plan do you already have?

If you’re not sure, pick the closest match. This helps us talk about “bare minimum” hearing care for your situation.

For many chemo and IV antibiotic regimens, a baseline hearing test near the start, at least one check during treatment, and a follow-up a few months after are common building blocks of monitoring.

Question 4
Have you noticed any new hearing or balance changes?

Check any that apply in roughly the last few weeks or months. If you’re not sure, it’s okay to guess.

Sudden big changes, especially in one ear, or new neurologic symptoms can signal emergencies. This tool will always recommend urgent evaluation in that situation.

Your suggested starting place

Educational triage

As you answer, we’ll suggest a starting point for hearing care around your treatment: emergency/urgent evaluation, treatment‑phase monitoring, post‑treatment follow‑up, or long‑term preventive care. You can screenshot the final summary and bring it to your clinicians.

Red-flag symptoms

This looks emergent: seek urgent medical care now

Based on your answers, you reported sudden big changes in hearing (especially in one ear) and/or new neurologic warning signs such as facial weakness, trouble speaking, severe headache, vision changes, or serious difficulty walking.

These patterns may signal problems that are time-sensitive for hearing and brain health. This navigator cannot tell how serious things are, so it leans strongly toward safety.

  • In many places, this combination of symptoms is treated as a medical emergency.
  • If you are in the U.S. and can do so safely, consider calling emergency services (for example, 911) or going to the nearest emergency department.
  • Use direct language such as: “Sudden hearing loss,” “sudden one-sided hearing loss,” or “new severe dizziness plus neurologic symptoms.”
  • Tell them which treatment or medicine you’re on (for example, “I’m getting chemotherapy called cisplatin” or “I’m on strong IV antibiotics”).
Do not change medicines on your own

Even when a medicine can affect hearing, stopping it suddenly may be unsafe. The safest path is to get urgent medical help so clinicians can weigh all the risks and benefits with you.

After emergency issues are addressed, you can ask whether a formal hearing test and follow‑up ototoxicity monitoring are appropriate in your situation.

Before treatment · No baseline yet

Ask for a baseline hearing test before or near the start

You haven’t started treatment yet, or you’re right at the beginning, and there hasn’t been a hearing test connected to this treatment so far.

Many programs aim for a baseline hearing test before the first dose or as close as possible to the start of chemotherapy or IV antibiotics, so that any changes later can be compared to where you started.

“Bare minimum” to ask for:

  • A baseline hearing evaluation with an audiologist, ideally:
    • Before treatment begins, or
    • Within the first few days or first cycle if things are already moving quickly.
  • Clarify: “If my hearing changes, who should I contact first—oncology, infectious disease, or audiology?”
  • Ask whether your program typically does at least one check during treatment and one follow‑up a few months after treatment.
Sample language for your care team

“I’ve read that some chemo and IV antibiotics can affect hearing. Could we add a baseline hearing test before or early in treatment so we have something to compare against later?”

Before treatment · Baseline in place

You’ve done the first step—now confirm the follow-up plan

You’ve already had a baseline hearing test tied to this treatment. That’s a key building block of ototoxicity monitoring.

The next step is to make sure there’s a clear plan for checks during and after treatment, especially if you’re receiving medicines known to affect hearing (for example, certain “‑platin” chemotherapies or IV antibiotics ending in “‑mycin” or “‑micin”).

“Bare minimum” to ask for now:

  • Confirm that your baseline will be used to watch for changes in:
    • High‑frequency hearing (often where changes show up first).
    • Speech‑range hearing that affects everyday communication.
  • Ask whether your plan includes:
    • At least one check during treatment (for example, mid‑course), and
    • One follow‑up a few months after treatment ends.
Sample language for your visit

“I’m glad we did a baseline hearing test. Can we map out when we’ll re‑check my hearing during treatment and once things are done, so changes don’t sneak up on us?”

During treatment · No hearing test yet

It’s not too late to ask for hearing monitoring

You’re already in treatment that may affect hearing, and no one has checked your hearing specifically for this course yet.

Even if the ideal “before treatment” baseline didn’t happen, it can still help to: get a first hearing test now and then track changes from here.

“Bare minimum” to ask for now:

  • A hearing evaluation with an audiologist as soon as reasonably possible during treatment.
  • A plan for at least:
    • One check during treatment (this first test can double as baseline), and
    • One follow‑up a few months after treatment ends.
  • Clear instructions on who to call if you notice new tinnitus, muffled hearing, or imbalance: oncology/ID, audiology, or primary care.
What to say when you message or call

“I’m in the middle of treatment with medicine that can affect hearing. I haven’t had a hearing test yet. Could we add one now, and set up at least one follow‑up while or after I’m on this medicine?”

During treatment · Baseline exists

Use your baseline to guide at least one check during treatment

You’re in the middle of treatment, and you’ve had at least one hearing test connected to this course. That’s a solid start.

For many high‑risk treatments (such as cisplatin or certain IV antibiotics), programs aim for:

  • A baseline near the start of treatment,
  • At least one check during treatment (often focused on the highest frequencies first), and
  • Post‑treatment follow‑up to see where things settle over time.

Questions you can bring to your team:

  • “When is my next planned hearing check during treatment?”
  • “If I notice new ringing, muffled hearing, or imbalance, can I be seen sooner than the routine schedule?”
  • “Will we also check hearing a few months after treatment ends?”
Side note

If hearing changes show up first in ultra‑high frequencies (beyond everyday speech), your audiology team may still choose to follow them closely, since they can be early warning signs. That doesn’t automatically mean you’ll lose all speech‑range hearing, but it’s worth taking seriously.

After treatment · No hearing tests yet

Consider a post-treatment hearing check

Your treatment has ended within about the last year, and there hasn’t been a formal hearing test linked to that care.

Some people notice changes only after treatment is done. Even if you’re not sure anything has changed, it can help to get a “new baseline” now, in case things shift later.

“Bare minimum” to ask for:

  • A hearing evaluation with an audiologist sometime in the first year after treatment— sooner if you’ve noticed ringing, muffled hearing, or imbalance.
  • A chance to talk about:
    • Whether your past treatment carries ongoing risk to hearing.
    • How often (if at all) ongoing hearing checks are recommended for you.
Sample language for your clinicians

“I had treatment that can affect hearing last year. I never had a hearing test for it. Could we schedule one now so we know where things stand?”

After treatment · Some testing already done

You have data—now turn it into a long-term plan

You’ve already had at least one hearing test connected to your past treatment. That’s helpful for understanding where things landed.

Depending on how your hearing looks now, your care team might recommend:

  • Watching and re‑checking only if new symptoms appear, or
  • Periodic monitoring, especially if you had high‑risk treatment to the ears or head/neck.

Questions to bring to your next visit:

  • “Does my hearing test suggest I should have regular follow‑up (for example, yearly)?”
  • “If I notice new ringing, muffling, or imbalance, how quickly should I try to be seen?”
  • “Are there things I can do now (like hearing protection or devices) to protect or support my hearing?”
Long-term medicines / not sure about risk

Start with a medication review and baseline hearing test

You’re on one or more long‑term medicines, or you’re not sure whether your medicines affect hearing. Over time, medicine combinations, kidney function, and other health conditions can all influence risk.

Reasonable starting steps:

  • Ask your primary care clinician or specialist for a medication review that includes hearing risk. Typical medicines people ask about include:
    • Certain water pills (loop diuretics).
    • Some IV antibiotics and chemotherapy drugs.
    • Long‑term very high‑dose aspirin or related medicines.
  • If you haven’t had one, consider a baseline hearing test so you have a reference going forward.
How to frame the conversation

“I take a few medicines and I’ve read some can affect hearing over time. Could we review whether any of mine are in that category, and whether a baseline hearing test would be helpful?”

Long-term medicines · Hearing already being checked

Fine-tune how often you’re checked and what is tracked

You’re already getting periodic hearing tests. That’s an important safety net, especially if you’re on medicines with potential hearing side effects.

Questions to refine your plan:

  • “Given my medicines and health conditions, how often do you recommend hearing checks?”
  • “If my medicines change—for example, if we add a chemo drug or strong IV antibiotic—should my hearing monitoring change too?”
  • “If I notice sudden changes between routine visits, how should I get back to you—portal message, phone call, or urgent visit?”
Pro tip

Keeping copies of your hearing tests (audiograms) over time makes it easier for new clinicians to see the big picture if things change later.

You identified as a clinician or professional

Use this as a patient education scaffold, not a protocol

You’re using this navigator in a professional role. It’s designed to give patients and families language and expectations around ototoxicity monitoring, based on widely used concepts such as:

  • Baseline audiometry (including extended high frequencies) before or soon after treatment starts.
  • Targeted monitoring during treatment, often using high‑frequency and SRO‑based approaches.
  • Post‑treatment follow‑up to characterize outcomes and support rehabilitation.

Local protocols will rightly vary by cancer center, ID service, and resources. This tool is meant to support conversations like:

  • “Here’s why we’re recommending a baseline before your first cisplatin cycle.”
  • “Even if we can’t see you before every dose, here’s our minimum monitoring plan.”
  • “If you notice X, Y, or Z between visits, that’s a reason to let us know sooner.”
Integration ideas

Consider linking this tool from patient‑facing education pages or after‑visit summaries for high‑risk regimens, so patients know that hearing monitoring is a “real thing,” not a luxury add‑on.

We couldn’t clearly sort your answers

Try adjusting your answers, or focus on questions for your team

The combination of answers you chose doesn’t clearly land in one of the main paths this tool uses (before treatment, during treatment, after treatment, or long‑term medicines).

That’s okay—real life is messy, and this navigator is only a rough guide. You can:

  • Revisit the earlier questions and choose the closest‑fitting options, or
  • Use these core questions at your next visit:
    • “Does anything I’m taking now affect hearing or balance?”
    • “Should I have a baseline or follow‑up hearing test?”
    • “If I notice sudden changes, who do I contact first?”

Building Your Hearing & Treatment Care Team

Ototoxicity monitoring works best when oncology, infectious disease, primary care, audiology, and rehab all share the load. This navigator is a starting point. Use it to organize your questions, then work with your own clinicians to decide what makes sense for you.
