Who’s Affected?

Did you or a loved one suffer from cerebellar atrophy or cerebellar degeneration while taking Dilantin medication?

Studies show that the long term side effects of Dilantin (phenytoin) includes an increased risk of developing cerebellar atrophy, also known as cerebellar degeneration.

Cerebellar atrophy can affect movement, coordination, and speech.

Dilantin, generic phenytoin, is a commonly prescribed antiepileptic drug, used for treating those who suffer from epilepsy and seizures. Cerebellar degeneration is one of the most significant Dilantin side effects that has been linked to the seizure medication.

What is Dilantin?

Dilantin is an anticonvulsant medication prescribed to people who suffer from seizures. It was developed in the early 1900s and was one of the first anticonvulsant drugs created.

The generic version of Dilantin is phenytoin. Dilantin can be administered orally and intravenously.



It helps prevent seizures that affect the entire brain (tonic-clonic seizures) as well as seizures that affect only one half or part of the brain (partial seizures). It is often used to prevent seizures during and after brain surgeries.

Dilantin is also prescribed to treat irregular heartbeats (arrhythmia), neuropathic pain, and bipolar disorder. While it is not approved for treating mood disorders like bipolar disorder, this is one of the off-label uses.

Doctors are allowed to prescribe drugs for off-label uses, but drugmakers are not supposed to push medications for any use until receiving approval for that purpose from the FDA.

What are the Dilantin side effects?

There are several side effects linked to Dilantin. As a drug that produces changes in the chemistry of the body, Dilantin side effects are to be expected.

Some of the minor side effects of Dilantin include:



  • Gum problems
  • Nausea
  • Stomach Cramps
  • Decreased appetite
  • Insomnia
  • Excessive hair growth
  • Headaches
  • Nervousness

The Dilantin side effects that are more serious include:

  • Bone marrow problems
  • Cerebellar atrophy
  • Hypotension
  • Liver Damage
  • Mild tremors
  • Neuropathy
  • Osteoporosis
  • Suicidal tendencies
  • Stevens Johnson Syndrome (SJS)
  • Birth defects, if taken while the patient is pregnant

What is Cerebral Atrophy?

Cerebral atrophy (atrophy of the brain) occurs when brain tissue degenerates.

When any tissue atrophies, it means that there are cells that are lost. In the case of the brain, this means the neurons in the brain and the connections between them are lost.

Cerebral atrophy can be generalized, which means the entire brain has shrunk; or it can be focal, affecting only a certain area of the brain. In focal cerebral atrophy only the functions that are controlled by that area of the brain are affected. [Source: BrainFacts.org]

Cerebral atrophy can be caused by a variety of diseases and injuries including:

  • Alzheimer’s disease
  • Cerebral palsy
  • Dementia
  • Infection diseases (AIDS, encephalitis, neurosyphilis)
  • Multiple sclerosis
  • Stroke
  • Traumatic brain injury

What is cerebellar atrophy?

Cerebellar atrophy

is a type of focal cerebral atrophy marked by a degeneration of the cerebellum, which is the part of the brain that sits under the cerebrum, behind the brain stem. It is also called cerebellar degeneration.

It is divided into two hemispheres. The cerebellum helps regulate voluntary movements such as posture, balance, coordination, and speech. It’s what allows for smooth, balanced, and precise movement.

What are the symptoms of cerebellar atrophy?

Damage to the cerebellum results in a lack of balance, slow movements, tremors, which causes shaking, and unstable eye movements. It can make certain physical tasks difficult and unsteady. The symptoms of cerebellar atrophy are similar to a stroke. Someone with cerebellar degeneration may also appear drunk.

Symptoms of cerebellar atrophy include:

  • Unsteady, lurching walk, which often includes a back and forth tremor in the main part of the body
  • Slow, unsteady, jerky movements in the arms or legs
  • Slow and slurred speech
  • Nystagmus: small rapid movements in the eyes.
  • Memory loss

What causes Cerebellar Atrophy?

Cerebellar atrophy causes

include stroke, Multiple Sclerosis, tumors, seizures, and other cerebellar disorders. Cerebellar degeneration has also been linked to toxins in the brain from ethanol, chemotherapy treatments, and Dilantin medication.

According to research on the link between cerebellar atrophy and Dilantin, cerebellar atrophy tends to show up in patients after long term use of Dilantin and when drug serum levels are above the therapeutic range. However, cerebellar atrophy has also reportedly occurred when the drug level appeared to be in the normal range.

Several studies have shown that cerebellar toxicity caused by long-term use of Dilantin can cause cerebellar atrophy.

A study published in 2003 found that moderate to severe atrophy of the cerebellum was linked to long term use of Dilantin.

Studies have also found that cerebellar degeneration can also affect children who take Dilantin medication to treat their epilepsy.

Since seizures can also cause cerebral atrophy, a 1994 study took this fact into account because patients taking Dilantin typically suffer from seizures. That study, which was the first to look at the connection, found that patients exposed to Dilantin as a group had significantly smaller cerebellums compared to non-exposed patients.

How is Cerebellar Atrophy treated?

Recovery from cerebral atrophy and localized cerebellar atrophy is reportedly possible when patients stop taking Dilantin. Withdrawal from Dilantin medication is monitored by a doctor.

However, in some cases when there is chronic treatment with Dilantin toxicity that led to cerebellar atrophy, some of the injuries were permanent, specifically the cerebellar ataxia, which is the lack of muscle coordination.
