Getting rid of hallucinations depends entirely on what’s causing them. For some people, the fix is as straightforward as catching up on sleep or stopping a substance. For others, it involves medication, therapy, or both. The good news is that most hallucinations respond well to treatment once the underlying cause is identified.
Figure Out What’s Causing Them
Hallucinations have a wide range of triggers, and the treatment path looks completely different depending on the source. The major categories include psychiatric conditions like schizophrenia or bipolar disorder, neurodegenerative diseases like Parkinson’s or Lewy body dementia, substance use or withdrawal, severe sleep deprivation, trauma-related disorders, and certain medications. Even high fevers, grief, and sensory loss (like vision or hearing decline in older adults) can produce hallucinations.
This is why the first step isn’t treating the hallucination itself. It’s figuring out why it’s happening. A doctor will typically rule out medical causes (infections, neurological conditions, medication side effects) before considering psychiatric ones. If you’ve started a new medication and hallucinations followed, that connection matters. If you haven’t slept in two or three days, that matters even more.
When Sleep Deprivation Is the Cause
Sleep deprivation is one of the most common and reversible causes of hallucinations. Research tracking the progression of symptoms during extended wakefulness shows that psychotic features, including visual and auditory hallucinations, emerge predictably as time awake increases. The fix is simple in concept: sleep. In studies where participants were allowed to recover, 82% experienced complete resolution of all psychotic symptoms without any lingering effects.
Recovery isn’t instant, though. Participants in sleep deprivation studies needed roughly half the time they’d been awake to fully bounce back. So if you’ve been up for 100 hours, expect about 50 hours of sleep spread over several days before you feel completely normal. Some people felt “quite normal” after just one full night of recovery sleep, while others needed several days. If you’re experiencing hallucinations and you know you’ve been sleeping poorly or not at all, prioritizing sleep is the single most important thing you can do.
Medications That Treat Hallucinations
When hallucinations stem from a psychiatric condition like schizophrenia, antipsychotic medications are the primary treatment. These drugs work by reducing the activity of dopamine in certain brain pathways. In people experiencing hallucinations, dopamine signaling in these pathways is overactive, and antipsychotics bring it back toward a normal range.
Antipsychotics generally fall into two groups. Older medications (sometimes called “typical” antipsychotics) block dopamine receptors directly. Newer ones (“atypical” antipsychotics) also affect serotonin signaling, which can reduce side effects and broaden their effectiveness. A third category includes partial dopamine agonists, which modulate dopamine activity rather than simply blocking it. The therapeutic sweet spot for all of these is when roughly 65% to 80% of dopamine receptors in key brain areas are occupied by the medication. Too little and symptoms persist; too much and side effects become problematic.
For people with Parkinson’s disease or Lewy body dementia, the medication picture is very different. These individuals are uniquely sensitive to many standard antipsychotics, which can trigger a dangerous reaction called neuroleptic malignant syndrome. For mild to moderate hallucinations in dementia, doctors often start with a class of drugs that boost a brain chemical called acetylcholine. These can reduce both the frequency and severity of hallucinations. When hallucinations become more distressing or disruptive, low doses of specific atypical antipsychotics may be carefully introduced. One medication approved specifically for hallucinations and delusions in Parkinson’s disease works by targeting only serotonin receptors, avoiding the dopamine blockade that makes other antipsychotics risky for these patients.
Therapy That Targets Hallucinations Directly
Cognitive behavioral therapy adapted for psychosis (CBTp) is one of the most effective non-medication approaches. It doesn’t aim to eliminate hallucinations entirely. Instead, it changes your relationship with them: how you interpret them, how much distress they cause, and how much they disrupt your daily life. A typical course involves 16 to 20 sessions.
The therapy works in stages. First, a detailed assessment maps out the hallucinations: how often they occur, how long they last, what they say, what triggers them, and what beliefs you hold about them. Then the therapist introduces specific strategies. These include distraction techniques, exposure-based approaches where you practice focusing on the hallucinations rather than fleeing from them, and exercises that test your beliefs about whether the voices have power or control over you.
Research shows that CBTp combined with medication outperforms medication alone, with improvements in hallucination frequency, loudness, and the degree to which they disrupt daily functioning. Importantly, the gains hold up over time. Follow-up assessments found that people continued to improve even after therapy ended, particularly in how often they heard voices and their overall hallucination severity.
Techniques for Managing Hallucinations in the Moment
When a hallucination is happening right now, several grounding strategies can reduce its intensity. These fall into three categories.
- Cognitive strategies: Reading aloud, counting objects in the room, or humming can reduce the duration, loudness, and clarity of auditory hallucinations. These tasks compete for the same brain resources the hallucination is using. Some people also find it helpful to talk back to voices or deliberately focus on describing the hallucination in detail, which can paradoxically reduce its power.
- Behavioral strategies: Physically changing your environment helps. Go for a walk, move to a different room, or engage in a social interaction. Reading a book or starting a hands-on activity shifts your attention away from the experience.
- Physiological strategies: Exercise, even something as simple as jogging or using a stationary bike, can interrupt hallucinations. Relaxation techniques (without visualization, which can sometimes make things worse) reduce the anxiety that often amplifies hallucinations. Listening to music through headphones is another option. Some research even suggests wearing an earplug in your dominant ear may help with auditory hallucinations.
These aren’t cures. They’re tools for getting through a difficult moment, and different techniques work for different people. It’s worth experimenting to find what reliably helps you.
Brain Stimulation for Treatment-Resistant Cases
When hallucinations don’t respond to at least two different medication trials, they’re considered treatment-resistant. Repetitive transcranial magnetic stimulation (rTMS), a non-invasive procedure that uses magnetic pulses to alter brain activity, is an option at this stage. The treatment targets areas of the brain involved in auditory processing, particularly in the left temporal region.
Results are mixed but promising for specific groups. A large naturalistic study following 65 patients with treatment-resistant auditory hallucinations found significant improvements in hallucination severity, with the best response rate (40%) occurring after about nine weeks and roughly 30 sessions. Among patients who continued treatment for 17 weeks, hallucination severity dropped by nearly 59%. Younger patients responded significantly better than older ones. However, some randomized controlled trials have found that the benefits fade after a few weeks, and one meta-analysis of 27 trials couldn’t definitively confirm routine effectiveness. It’s a reasonable option to discuss if medications and therapy haven’t worked, but expectations should be realistic.
If You’re Caring for Someone Who Hallucinates
When a loved one is experiencing hallucinations, particularly someone with dementia or Alzheimer’s disease, your instinct may be to correct them. Don’t. Arguing about what is or isn’t real increases agitation without reducing the hallucination. Instead, acknowledge their emotional experience. If they’re frightened, comfort them. If they’re agitated, try gentle physical reassurance like holding their hand.
Distraction is your most practical tool. Guide them to a different room, go for a walk together, or redirect their attention to something tangible like a photograph or familiar object. Keep the environment calm by turning off television programs that could be confusing or upsetting. If they express paranoid beliefs or blame you for something, try not to take it personally or argue the point. Let them know they’re safe, and explain to other family members or visitors that the behavior is part of the condition, not a reflection of reality or intent.
Signs That Need Immediate Attention
Most hallucinations can be addressed through the approaches above, but some situations require emergency help. Call emergency services if someone experiencing hallucinations expresses a desire to harm themselves or others, hears voices instructing them to hurt someone, becomes very agitated or aggressive, has hallucinations that are rapidly getting worse, suddenly becomes confused, or stops making sense when they speak. These signs can indicate a medical emergency, a psychiatric crisis, or both.
