Long-Term Effects of Risperdal – Summary

risperdal serious negative long-term risksRisperdal (risperidone is the generic name) is high on the list of most frequently prescribed antipsychotic medications in the US. When one is in a mental health crisis, an antipsychotic medication may have been correctly prescribed. However, because each person can react differently to a medication, often side effects can occur that were not easily predicted. Sometimes side effects come on immediately, and sometimes they may disappear over time. However, others may develop over a longer period of time and may begin to overshadow any the benefits that the drug provided.6,7

Risperidone’s mechanism of action is not completely understood, but it is thought to suppress the expression of dopamine and possibly affect other natural hormones, and many systems in the body.

Further below we’ll talk about the possible reasons for some of the undesirable side effects associated with Risperdal, especially side effects and safety signals that may come with long-term use.1-5,9,10,14,16

But first, here is a summary of the possible long-term effects of Risperdal, which will be followed by an expanded description to better understand some of the most concerning ones where research has provided such information.

Long-term effects of Risperdal can include:
  • Fatigue, sedation
  • Increased appetite
  • Weight gain
  • High blood sugar, diabetes
  • Sexual dysfunction
  • Emotional blunting
  • Enlargement of the pituitary gland
  • Elevated prolactin (a hormone that regulates over 300 functions of the human body)
  • Gynecomastia (male breast enlargement)
  • Galactorrhea (male lactation)
  • Cardiovascular injury, i.e., stroke
  • Altered white blood cell count
  • Cognitive impairment
  • Motor (muscle movement) impairment
  • Seizures
  • Akathisia
  • Tremor
  • Dizziness
  • Anxiety
  • Blurred vision
  • Respiratory tract infection
  • Nasal inflammation
  • Excess salivation
  • Acid reflux, indigestion, pain in throat
  • Neuroleptic malignant syndrome (altered mental state + a cascade of potentially life-threatening symptoms)
  • Tardive dyskinesia
  • Parkinsonism
  • Dystonia – involuntary muscle contractions, twisting, or abnormal postures

In general, an antipsychotic medication is prescribed to quell emotional turbulence and agitation associated with conditions like psychosis, mania, or schizophrenia. This class of drugs is renowned for negative long-term effects that can add to a person’s burden of suffering.

BUT !!! A word of caution:

Over a long period of time, such medications can result in side effects that persist, resulting in a desire or need to stop taking the medication. However, there can be disastrous consequences in stopping risperidone abruptly as even missing a dose can result in a cascade of withdrawals. Always seek professional help before attempting to stop taking antipsychotic medications especially after long-term use of risperidone or similar drugs.

Why is Risperdal Prescribed?

Risperdal is FDA-approved for treating schizophrenia, mania in bipolar conditions, and irritability in autism. It is approved for both children, adolescents, and adults.

Off-label, Risperdal has also been used for anxiety, insomnia, borderline personality disorder, depression, conduct disorder, and other uses. Doctors can legally prescribe a medication for just about anything, even when no research supports such practices.

Risperdal has also been prescribed along with other medications when efficacy was poor – such as when an antidepressant or mood stabilizer failed, and similar scenarios.

Risperdal and Metabolic Changes

Risperdal has been on the market since the early 1990s. Since that time, research has sought to explain some of the long-term effects associated with Risperdal. Research out of Korea has shown long-term metabolic changes associated with antipsychotic medications. These adverse effects include abdominal obesity, significant weight gain, insulin resistance/type 2 diabetes, as well as hypertension.11

It was found that aerobic exercise and diet management were helpful in reducing the obesity and weight issues associated with antipsychotic medications.18

Risperdal’s Effects on the Pituitary Gland and Prolactin

It has been shown that over time, Risperdal very frequently overstimulates and enlarges the pituitary gland. The pituitary gland, among other functions, produces the hormone known as prolactin. Prolactin is involved with over 300 human body functions. Prolactin’s roles include to manage reproductive health, sexual function, fertility, lactation (expression of breast milk). menstruation, male breast augmentation, and many others.

Research published in the Frontiers in Psychiatry Journal reported that elevated prolactin levels were the leading side effect of Risperdal, and that it was the main reason for non-compliance – which can lead to hospitalization due to the crushing withdrawals when the drug is abruptly stopped.19

When prolactin is elevated, the long-term effects include development of tumors in the pituitary gland, anxiety, depression, sexual impairment, hostility, mood alterations, memory loss, breast cancer, psychosis, cardiovascular risks, and many others.

Risperdal and Long-Term Sexual Impairments

The sexual impairments of Risperdal affect up to 80% of both females and males – including children – taking this medication. The sexual side effects are thought to be associated with the suppression of dopamine receptors, and is also thought related to how the drug impacts the adrenergic and histamine and possibly other receptors.16,17,19

Sexual side effects of Risperdal can include:
  • Irregular menstruation, menstruation stopping altogether
  • Priapism (persisting and painful penile erection)
  • Male breasts
  • Male lactation (milk from nipples)
  • Female lactation not associated with childbirth
  • Loss of libido
  • Anorgasmia in both males and females

The Development of Movement and Neurologic Disorders

Risperdal can induce several types of movement and neurologic disorders, shown below. Many but not all of these have been found to reverse, at least in part, after cessation of the drug. Some may persist even after discontinuation, and some may become permanently disabling or fatal. 14,17

Movement and neurologic disorders associated with long-term Risperdal include:
  • Parkinson’s syndrome
  • Tardive dyskinesia (often irreversible)
  • Akathisia
  • Neuroleptic malignant syndrome (altered mental state, lead-pipe rigidity, fever, can be fatal)
  • Floppy iris syndrome

What are the Various Brand Names for Risperidone?

Risperidone is sold under various brand names including these:
  • Risperdal
  • Uzedy
  • Perseris
  • Risperdal Consta
  • Risva
  • Rykindo

Risperdal’s Black Box Warning

risperdal risperidone carries a black box warningThe FDA’s black box warning 1,2 on Risperdal’s package must include the following statement:

WARNING: INCREASED MORTALITY IN ELDERLY PATIENTS WITH DEMENTIA-RELATED PSYCHOSIS
See full prescribing information for complete boxed warning. Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. RISPERDAL® is not approved for use in patients with dementia-related psychosis. (5.1)

Both prescribers and patients and their loved ones should read the package insert and get any questions answered about prescribed drugs.

How Do Holistic Treatments Approach Mental Health?

When it comes to severe mental health crises, time and other constraints often make immediate medication the only available choice. However, after the crisis is seen to pass, holistic treatments may offer other pathways to recovery of mental health issues. For example, CBT is recognized as an excellent tool for mental health recovery, for many different issues one may struggle with.12,13

holistic approach to mental healthNot everyone may be a candidate for total discontinuation of antipsychotic medications. But some most definitely have had success with this approach, when dose reduction is done correctly, at a very slow and measured pace, and with adequate supports in place to ensure stable long-term recovery, including the reversal of overstimulation of the pituitary gland and the effects of over-secretion of prolactin.7,8,16

It is a known fact that schizophrenia and other syndromes are prone to misdiagnosis for a wide range of reasons.15 And there is a rich evidence base for the effectiveness of non-pharmacological treatment for first-episode psychosis, mania, depression, insomnia, and many other of the afflictions that plague our modern life. Diet modification, counseling, neurotoxin removal, physical exercise and many others are some of the many holistic treatments ATMC offers.

ATMC’s first premise is to search for underlying causes, the root causes that precipitated or contributed to a mental health crisis or set of symptoms that required intervention. And after the crisis has abated, there is always time to explore the reasons for symptoms. And it is possible that addressing the underlying causes can bring about recovery without relying on a lifetime of being heavily medicated.

What Can a Person Do to Safely Reduce or Discontinue Antipsychotic Medications?

If you have other questions about Risperdal, and long-term effects, and treatment options, don’t hesitate to call on us for information. This is our area of expertise.

There are a wide range of safe and healthy alternatives to Risperdal that can be gradually blended into a personalized Risperdal withdrawal program at the Alternative to Meds Center. 

Sometimes a drug just isn’t working for a person they way they hoped it would. The long-term effects may have created a scenario where alternatives could provide a better recovery path. But in any case one should never abruptly discontinue any antipsychotic medication. Doing so could be catastrophic.
