You started a new medication and your hearing changed. Before assuming it's a side effect, here's the one thing worth checking first.
You started a new medication a few weeks ago. Since then, your hearing feels slightly muffled — or there's a faint ringing you didn't have before. You look up the side effects. Hearing changes are listed. You assume it's the drug.
But what if it isn't?
Some medications genuinely do affect hearing
This is real. A class of drugs known as ototoxic medications can cause hearing changes, tinnitus, or balance problems. The most commonly cited examples include:
- High-dose aspirin or NSAIDs — chronic use at high doses (often for arthritis or cardiovascular conditions) can cause temporary tinnitus or muffled hearing, usually reversible when the dose is reduced
- Loop diuretics (furosemide, bumetanide) — prescribed for heart failure or high blood pressure; can affect the fluid balance in the inner ear at high doses
- Aminoglycoside antibiotics (gentamicin, neomycin, streptomycin) — powerful antibiotics for serious infections; ototoxic effects are dose-dependent and can be permanent in severe cases
- Chemotherapy drugs (cisplatin, carboplatin) — well-documented causes of hearing changes, often monitored during treatment
According to the American Academy of Audiology, over 200 medications have known ototoxic potential. If you've recently started one of the above and your hearing has changed, it's worth mentioning to your prescribing doctor.
But here's the step most people skip entirely.
Ear wax can cause every single one of those symptoms
Muffled hearing. Tinnitus. A blocked or full feeling. Even mild dizziness. These are also the classic signs of cerumen impaction — a buildup of ear wax that presses against the eardrum.
According to the Cleveland Clinic, cerumen impaction affects around 6% of the general population and up to 35% of older adults. It's extremely common, often painless, and easy to overlook because you can't see inside your own ear canal without a camera.
Here's where it gets more complicated: some medications indirectly affect ear wax. Antihistamines — taken by tens of millions of people for allergies, colds, or sleep — can dry out secretions throughout the body, including ear wax. When ear wax becomes drier and harder, it's more likely to become impacted. Decongestants can affect Eustachian tube pressure, creating that "stuffed up" feeling that has nothing to do with the inner ear.
So you may genuinely be experiencing a medication effect — just not the one you think.
The symptoms of ototoxic drug effects and ear wax impaction are nearly identical. Without looking inside, there's no reliable way to tell which one you're dealing with.
The problem with assuming before you look
Most people in this situation do one of two things: they call their doctor and describe the symptom, or they look up the medication's side effects online and conclude it's a match.
Neither approach tells you what's physically happening inside your ear canal right now.
A doctor can check — but booking an appointment, waiting, and traveling to a clinic is a significant investment of time, especially if it turns out to be a simple wax buildup. And reviewing a side-effect list only tells you what could happen to some patients, not what is happening in your specific ear at this moment.
The most useful first step is to look. If you can see a wax buildup, that's a meaningful data point — and something you may be able to address at home before making any further decisions. If your ear canal looks clear, that's equally useful information: the symptom is more likely coming from somewhere a camera can't reach, which is when a doctor visit makes the most sense.
How Slivor changes the first step
This is exactly what Slivor is built for. The Slivor VisioEar is a 1080p FHD ear camera with integrated LED lighting that streams live video to your phone. You can see what's inside your ear canal — clearly, in real time, without guessing.
More than 100,000 households already use Slivor to check their ears at home. That includes people who discovered that the "medication side effect" they'd been managing for weeks was actually a wax buildup that resolved with a few drops of softening oil.
One engineering detail worth knowing: Slivor ships with 8 medical-grade silicone tips. Soft silicone conforms gently to the ear canal and flexes with its natural curve. If your ears are already sensitive, that gentleness is something you'll notice on first use.
The right order of operations
- Look inside your ear first — use Slivor to see whether there's a visible wax buildup
- If there's wax, try approved softening drops and monitor whether the symptom improves over a few days
- If the canal is clear (or the symptom doesn't improve), contact your prescribing doctor with that information
- Bring what you know — telling your doctor "I checked and there's no wax" is a more useful starting point than "I'm not sure"
This sequence doesn't replace medical advice. It makes the medical conversation you eventually have more productive.
Frequently asked questions
Can antihistamines cause ear wax buildup?
Antihistamines don't directly cause the body to produce more wax. However, they can dry out secretions — including ear wax — making existing wax harder and more prone to becoming impacted. If you take antihistamines regularly and notice your ears feeling blocked, checking inside with a camera is a practical first step.
Can aspirin cause tinnitus?
Yes — high doses of aspirin (typically 8 or more standard tablets per day, used in some arthritis protocols) are a well-documented cause of tinnitus. The effect is usually reversible when the dose is reduced. That said, tinnitus from ear wax impaction is also extremely common. If you're on regular aspirin and develop ringing, looking inside your ear first is the most informative thing you can do before calling your doctor.
How do I know if my hearing change is from medication or ear wax?
The most reliable approach is to look inside your ear. If there's a visible wax buildup, try softening it with approved drops, then see whether the symptom improves. If it does, wax was the culprit — or at least a major contributing factor. If the canal looks clear and the symptom persists, that's when it's appropriate to contact your prescribing doctor about a medication review.
Is it safe to use an ear camera if I'm on blood thinners?
Yes — an ear camera is non-invasive. You're illuminating and viewing the ear canal, not inserting anything sharp. Slivor's medical-grade silicone tips are soft and flexible. The thing to avoid when on blood thinners is scraping or aggressively pushing wax, which could irritate the canal. Slivor shows you what you're dealing with so you can decide whether gentle softening drops are enough or whether professional removal is the safer call.
Should I stop my medication if I notice hearing changes?
Never stop a prescribed medication without speaking to your doctor first. Hearing changes are worth mentioning at your next appointment — but so is the possibility that ear wax is contributing. The more information you can bring to that conversation, including what you observed inside your ear, the more useful the discussion will be.
Not sure if it's wax or a side effect? See for yourself.
