Medications for Visual Snow Syndrome (VSS)

Welcome to our guide on medications for Visual Snow Syndrome (VSS). Here, you will find information on medications explored in research studies as potential treatments, their effects, and the challenges of finding safe and effective options.

What Medications Have Been Researched for VSS?

While no medication has consistently proven effective for Visual Snow Syndrome (VSS), various options have been studied in hopes of relieving symptoms. Below are the medications researched, their intended effects, and the outcomes observed among VSS patients. Although a few individuals experienced slight relief, overall results have been mixed, with many patients seeing little to no improvement or experiencing side effects, including worsening of symptoms or, in some cases, the onset of new VSS symptoms. Many VSS patients have also expressed that they attribute the use of various medications, including the following, to the onset of their condition. Even if they have provided relief for some, these medications have also allegedly been linked to the onset of VSS or increased symptoms in other cases. No single medication has had the same effect on everyone with VSS, nor do these medications help everyone. Otherwise, every VSS patient who took them would have experienced improvements or the same effects and treating VSS would be definitive, which is not to this date.

It is imperative to consult a qualified medical professional, ideally with knowledge of VSS such as those in our Visual Snow Doctors & Specialists Directory, to ensure safety and determine what is best for you based on your specific symptoms and personal medical history.

Lamotrigine: An anticonvulsant typically used for seizure control and mood stabilization. It provided limited improvement for a few VSS patients but was generally ineffective. In some cases, it worsened symptoms, suggesting it does not address the underlying visual processing disruptions of VSS. The best data available shows lamotrigine being effective in 8 out of 36 cases (22%).

Topiramate: Commonly prescribed for migraine prevention and seizure disorders. Results were mixed, with some patients reporting slight improvement, while others experienced worsened symptoms, including increased VSS severity. Side effects were often severe enough to outweigh any minor benefits. Data indicate that topiramate was effective in 2 out of 13 cases (15.4%).

Benzodiazepines

Typically prescribed for anxiety, muscle relaxation, and short-term relief of anxiety symptoms. Benzodiazepines provided only temporary symptom relief for some patients and did not effectively target VSS symptoms. Risks regarding dependency, tolerance, and side effects were also concerns, making them unsuitable for long-term use.

Acetazolamide

Used for conditions such as glaucoma and intracranial hypertension. While it theoretically could relieve visual disturbances, it showed limited efficacy in VSS patients. Side effects were often intolerable, and symptom relief was generally minimal or nonexistent.

Propranolol

A beta-blocker commonly used to treat high blood pressure and prevent migraines. In limited trials, it did not significantly improve VSS symptoms and was largely ineffective for managing the unique visual symptoms of VSS.

Onabotulinum Toxin A (Botox)

Botox injections are sometimes used for chronic migraines. In one case, ongoing Botox treatment was ineffective for VSS symptoms, particularly when other medications had failed. It remains under observation for potential symptom modulation.

Gabapentin and Pregabalin

Antiepileptic drugs sometimes used off-label for neuropathic pain and migraine prevention. While a few patients experienced slight symptom relief, the overall efficacy was low and side effect profile was high. These medications did not address the specific neurological mechanisms of VSS and, in some cases, worsened visual disturbances.

Antidepressants (SSRIs, Tricyclics, Atypical)

Various classes of antidepressants are used for mood disorders and migraines. A small number of patients reported improvements in VSS symptoms, particularly with tricyclic antidepressants. However, for many, these medications had no significant effect or worsened visual symptoms, with additional side effects and interactions complicating their use.

Methylphenidate (ADHD medication)

A stimulant prescribed for attention-deficit hyperactivity disorder (ADHD). Methylphenidate was noted as a potential trigger for VSS in one case, with symptoms improving when the dose was reduced. However, lowering the dose worsened ADHD symptoms, and switching to Atomoxetine provided ADHD control without visual snow effects.

Sumatriptan (Triptans)

A medication for acute migraine relief. Occasionally used in VSS cases with mixed results, it was ineffective as a long-term treatment and did not consistently improve VSS-related visual disturbances.

Verapamil

A calcium channel blocker that has shown some potential in alleviating VSS symptoms. Some patients reported reduced visual disturbances with its use. It does not always yield relief of symptoms.

Nortriptyline

A tricyclic antidepressant that has provided relief for certain VSS patients, particularly with regard to visual disturbances. However, as with other treatments, its effectiveness varies by individual.

Valproate

Another anticonvulsant used for mood stabilization and seizure disorders. Some patients reported symptom alleviation, though its efficacy remains inconsistent across studies.

Flunarizine and Cinnarizine

Both are calcium channel blockers used primarily for vertigo and migraine prevention. Some patients experienced alleviation of VSS symptoms after taking both medications, suggesting a potential benefit for those with VSS. However, its effectiveness varies by individual.

Magnesium

This mineral supplement is sometimes recommended for neurological health, and a few VSS patients reported symptom alleviation with magnesium supplementation.

Challenges in Developing Medications for VSS

Researchers agree that identifying effective treatments for VSS requires a deeper understanding of the disorder itself. Currently, VSS is thought to involve complex brain network disruptions, which means any medication would need to target these specific mechanisms to be safe and effective for VSS patients.

Key Challenges

  1. Complexity of VSS as a Network Disorder: VSS appears to affect specific neural pathways, especially those related to color and visual processing. Research also suggests that dysregulation in neurotransmitters, such as glutamate and serotonin, may contribute to the hyperexcitability of the brain, a state where neurons become overly responsive to stimuli. This hyperexcitability likely disrupts normal visual processing and heightens sensitivity to visual disturbances. The roles of these neurotransmitters highlight the challenges in developing targeted medications without fully understanding these underlying mechanisms.

  2. Side Effects and Safety Concerns: Many patients report that existing medications either do not improve symptoms, worsen them, or introduce serious side effects. The limited effectiveness of these treatments can leave patients feeling discouraged, as they often go through trials with little to no benefit. Additionally, some medications not only fail to alleviate symptoms but can intensify VSS symptoms or even introduce new visual disturbances, making the treatment process risky.  
  3. Historical Cases Linking Medication and VSS: The first documented link between medication and VSS was noted by Frank D. Carroll in 1994, who observed the onset of VSS in patients using digitalis, a heart medication. This finding highlights that certain medications may trigger or worsen VSS symptoms rather than alleviate them. This complicates both diagnosis and treatment, as it’s difficult to distinguish between naturally occurring VSS and VSS aggravated by medication. Additionally, the potential for medications to worsen symptoms limits treatment options, prompting doctors to approach certain drugs with caution.


Due to these risks, careful consideration and thorough understanding of Visual Snow Syndrome (VSS) are crucial before introducing pharmacological interventions. Global VSS researchers advocate for additional studies that can clarify the condition’s biomarkers and underlying mechanisms, which will be essential for developing safe, targeted treatments.

Ongoing Research and VSI's Commitment

The Visual Snow Initiative (VSI) supports and funds research into Visual Snow Syndrome treatments, both pharmacological and noninvasive, with the goal of finding safe and effective solutions. Researchers specializing in Visual Snow Syndrome, with access to necessary resources and expertise, are conducting studies that will continue to shed light on treatment options.
