Hallucinations can often be reduced or stopped entirely, but the right approach depends on what’s causing them. Some hallucinations stem from psychiatric conditions like schizophrenia, others from neurological diseases like Parkinson’s, and still others from reversible triggers like sleep deprivation, dehydration, or medication side effects. Identifying the underlying cause is the single most important step, because treating that cause frequently resolves the hallucinations on its own.
Rule Out Reversible Triggers First
Not all hallucinations signal a chronic condition. Several common physiological states can produce them, and correcting the trigger often leads to a full recovery. Sleep deprivation is one of the most frequent culprits. After 24 to 48 hours without sleep, the brain begins generating perceptions that aren’t there, typically visual distortions or sounds. Restoring normal sleep usually stops them within a day or two.
Dehydration, electrolyte imbalances, and metabolic disorders can also cause a state called delirium, which frequently includes hallucinations alongside confusion and disorientation. Infections (especially urinary tract infections in older adults), high fevers, and sudden medication changes are other well-known triggers. Treatment in these cases focuses on the root problem: rehydrating, correcting the imbalance, treating the infection, or adjusting the medication. In the meantime, keeping the room quiet, well-lit, and familiar helps. Having a clock or calendar visible and family members nearby reduces disorientation while the underlying issue is being addressed.
In-the-Moment Coping Techniques
When a hallucination is happening right now, several strategies can reduce its intensity or duration. These fall into three categories: cognitive, behavioral, and physiological.
Cognitive techniques involve occupying the language centers of your brain. Reading aloud, counting objects in the room, or humming can reduce the loudness, clarity, and duration of auditory hallucinations. The more mentally engaging the activity, the better it tends to work. Some people find it helpful to describe the hallucination in detail out loud, which can create a sense of distance and control. Others practice “talking back” to voices, directly challenging what they hear rather than passively accepting it.
Behavioral strategies center on changing your activity or social environment. Going for a walk, starting a conversation with someone, or picking up a book can redirect your attention. Men tend to prefer solitary coping strategies while women often benefit more from social interaction, though this varies widely from person to person.
Physiological approaches use the body to calm the nervous system. Relaxation exercises that don’t involve mental imagery work best, since people prone to hallucinations can have difficulty distinguishing internal images from external reality. Physical activity like jogging or cycling has shown benefit. Listening to music through headphones helps some people, and using an earplug in the dominant ear (the right ear for right-handed people) has been found to reduce auditory hallucinations in certain cases.
Medication for Persistent Hallucinations
When hallucinations are part of a condition like schizophrenia, antipsychotic medication is the only drug class proven to reliably reduce their frequency and severity. These medications work by dampening overactive dopamine signaling in the brain, which is closely linked to psychotic symptoms.
Most people start on one antipsychotic and give it two to four weeks to take effect. If the first medication doesn’t provide adequate improvement, switching to a different one is the standard next step. For people who don’t respond to two different antipsychotics, clozapine is generally considered the strongest option, though it requires regular blood monitoring due to potential side effects.
One critical point about antipsychotic treatment: the dose that stops hallucinations is the dose you need to stay on. Cutting the dose by half increases the risk of relapse two- to threefold. Staying on the effective dose long-term provides the lowest chance of hallucinations returning.
A Newer Option Worth Knowing About
A medication called Cobenfy, approved for schizophrenia, works through an entirely different mechanism than traditional antipsychotics. Instead of blocking dopamine receptors directly, it activates specific receptors in the brain that dial down dopamine signaling through an indirect route. In clinical trials, people taking Cobenfy showed significantly greater improvement in psychosis scores compared to placebo, with nearly twice as many cognitively impaired participants showing meaningful improvement by week five (39% versus 19%). Notably, Cobenfy has not been associated with the weight gain, movement disorders, or heart rhythm changes that can accompany traditional antipsychotics.
Hallucinations in Parkinson’s Disease
Parkinson’s-related hallucinations require special care because standard antipsychotics can worsen the movement symptoms of the disease. Pimavanserin is the only medication specifically approved for Parkinson’s disease psychosis. It works by targeting serotonin receptors rather than dopamine, so it doesn’t interfere with the dopamine replacement therapy that Parkinson’s patients depend on for mobility.
In clinical studies, 76% of individuals treated with pimavanserin showed clinical improvement in psychosis, and that improvement held up over two years of follow-up. Compared to other antipsychotics used in this population, pimavanserin was associated with 35% lower mortality and roughly half the rate of falls and fractures. Clozapine also works for Parkinson’s psychosis but carries heavier monitoring requirements. Quetiapine, despite being widely prescribed for this purpose, has no strong evidence of actually reducing hallucinations in Parkinson’s patients. It may ease agitation and distress without addressing the hallucinations themselves.
Therapy That Changes Your Relationship With Voices
Cognitive behavioral therapy adapted for psychosis (sometimes called CBTp) takes a different angle than medication. Rather than trying to eliminate hallucinations entirely, it focuses on reducing the distress and control they have over your life. This distinction matters because for many people, the most damaging aspect of hearing voices isn’t the sound itself but the belief that the voices are powerful, threatening, or must be obeyed.
CBTp helps people examine and challenge beliefs about their hallucinations. If someone hears commanding voices and feels compelled to comply, therapy works on dismantling the perceived authority of those voices. Over time, this leads to less fear, less compliance with harmful commands, and more active resistance. The hallucinations may still occur, but they lose their grip. For many people, this shift in relationship with the experience is just as valuable as a reduction in frequency.
Adjusting Your Environment
For people who experience visual hallucinations, particularly those with dementia or Lewy body disease, the physical environment plays a surprisingly large role. The brain tries to make sense of ambiguous visual information, and when its processing is impaired, it fills in the gaps with images that aren’t there. Certain objects and conditions reliably trigger this.
Patterned carpets, clothes hanging on walls or doors, dolls, and shadows cast by furniture or handrails are all documented triggers. In case studies, straightforward changes made a measurable difference: storing hanging clothes in closets, covering patterned carpets with plain tablecloths, reducing the number of dolls or figurines in a room, and using blindfold shades to cover faces on decorative items. Increasing indoor brightness and reducing shadowy areas also helps, since dim lighting forces the brain to interpret more ambiguous visual signals.
These adjustments are simple and cost nothing, but they require looking at a room through the eyes of someone whose visual processing is compromised. Walk through each space and note anything that could be misinterpreted: a coat on a hook that looks like a figure, a shadow that resembles a face, a busy pattern that seems to move. Removing or concealing these triggers won’t cure hallucinations, but it can meaningfully reduce how often they occur.
