3 min read 14-03-2025

Antipsychotic medications, also known as neuroleptics, are prescribed to treat a range of mental health conditions, including schizophrenia, bipolar disorder, and severe depression. While these medications can be highly effective in managing symptoms, it's crucial to be aware of their potential side effects. This article provides a comprehensive overview of these side effects, categorized for clarity and ease of understanding. Remember, this information is for educational purposes only and should not replace consultation with a healthcare professional. Always discuss any concerns about medication with your doctor or psychiatrist.

Common Side Effects of Antipsychotic Medication

Many people experience some side effects when starting antipsychotic medication. These are often mild and may lessen over time as the body adjusts. However, it's important to report any concerning symptoms to your doctor immediately.

Movement-Related Side Effects (Extrapyramidal Symptoms - EPS)

Acute Dystonia: This involves sudden, painful muscle contractions, often in the neck, face, or back. It can be frightening but is usually treatable with medication adjustments.
Akathisia: This manifests as inner restlessness and an inability to sit still. It can be very distressing and requires medical attention.
Parkinsonism: Symptoms mimic Parkinson's disease, including tremor, rigidity, slow movement (bradykinesia), and postural instability.
Tardive dyskinesia (TD): This is a serious, potentially irreversible movement disorder characterized by involuntary movements of the face, mouth, tongue, and limbs. Early detection and intervention are crucial.

Metabolic Side Effects

Antipsychotic medications can significantly impact metabolism, leading to:

Weight gain: This is a common and concerning side effect, increasing the risk of diabetes, heart disease, and other health problems. Lifestyle changes and medical intervention may be necessary.
Increased blood sugar (hyperglycemia) and diabetes: Regular blood sugar monitoring is essential, especially for those with a family history of diabetes.
Increased cholesterol and triglycerides: This raises the risk of cardiovascular disease. Dietary changes and medication adjustments may be necessary.

Other Common Side Effects

Beyond movement and metabolic effects, other common side effects include:

Sedation and drowsiness: This can interfere with daily activities and may improve over time.
Dry mouth: This can lead to dental problems if not addressed.
Constipation: Increasing fiber intake and fluids can help manage this.
Blurred vision: This usually resolves with time.
Orthostatic hypotension (low blood pressure upon standing): This can cause dizziness and fainting. Rising slowly can help minimize this.

Less Common but Serious Side Effects

While less frequent, some serious side effects require immediate medical attention:

Neuroleptic Malignant Syndrome (NMS): This is a rare but life-threatening condition characterized by high fever, muscle rigidity, altered mental status, and autonomic instability. Immediate hospitalization is necessary.
Agranulocytosis: This is a severe drop in white blood cells, increasing the risk of infection. Regular blood tests are crucial to monitor this.
Prolonged QT interval: This can lead to potentially fatal heart rhythm disturbances. An electrocardiogram (ECG) may be used to monitor this.

Managing Side Effects

The management of side effects depends on the individual and the specific medication. Strategies may include:

Medication adjustments: Your doctor may adjust the dose or switch to a different antipsychotic medication.
Lifestyle changes: Dietary modifications, exercise, and stress reduction techniques can help manage weight gain, blood sugar, and cholesterol levels.
Additional medications: Other medications may be prescribed to alleviate specific side effects, such as anticholinergics for EPS.
Therapy: Therapy can help manage the emotional distress associated with some side effects.

When to Seek Medical Attention

Contact your doctor or psychiatrist immediately if you experience:

Severe or worsening side effects
Sudden, unexplained changes in your mental state
High fever, muscle rigidity, or altered mental status (possible NMS)
Signs of infection (e.g., fever, sore throat)
