Lithium is short for lithium carbonate, a medication used to treat manic episodes in bipolar disorder and schizophrenia. Before starting treatment, certain precautionary steps are essential—including avoiding alcohol consumption, as combining lithium and alcohol can significantly affect both your mental and physical health.

Taking alcohol and lithium together may trigger side effects ranging from mild drowsiness to severe complications such as lithium toxicity and hypothyroidism. It’s crucial to be informed about the lithium and alcohol interaction and the risks involved.

If you are struggling with alcohol dependency, The Recovery Team provides medically assisted treatment in a safe and supportive environment.

Lithium helps calm agitation and manage manic episodes in mental health conditions.
Inform healthcare providers of your medical history and current medications before using lithium.
The reaction between lithium and alcohol may cause nausea, dizziness, and impaired thinking.
In severe cases, this combination can lead to lithium toxicity and hypothyroidism.

How Lithium Works

Lithium is a naturally occurring element used to stabilize mood in people with mental health disorders such as bipolar disorder, depression, schizophrenia, and anxiety. It works by modifying neurotransmitter activity in the brain, enhancing communication between nerve cells and helping regulate mood, behavior, and thought patterns.

Positive effects typically appear within two to three weeks. Lithium is also prescribed to individuals with severe suicidal ideation, helping reduce destructive thoughts. Due to its potential impact on the kidneys, regular blood tests and monitoring of lithium serum levels are necessary to avoid complications.

What to Know Before Using Lithium

Consult your doctor before taking lithium if you have a history of:

Breathing issues
Kidney problems
Heart disease
Thyroid disorders
Allergic reactions

Notify your healthcare provider if you are pregnant or planning to conceive. Lithium can interact dangerously with certain medications, including stimulants, opioids, and drugs for anxiety or infections, potentially leading to serotonin syndrome.

People taking lithium may experience dehydration, especially when dealing with vomiting, diarrhea, or excessive sweating. This is why patients are advised to drink extra water and carefully follow medical guidance.

Lithium and Alcohol

If you are using lithium to stabilize your mood and drinking alcohol with the hope of enhancing its calming effects, the result may be the opposite. Alcohol can reduce the effectiveness of lithium and worsen its side effects.

Like lithium, alcohol affects the brain’s neurotransmitters and can lead to mood swings. For individuals with bipolar disorder, the interaction between lithium and alcohol is especially dangerous, as it can worsen emotional instability and impair decision-making.

Some individuals may turn to alcohol for temporary relief in social or emotional situations, but this is not a viable solution for managing mental illness. Long-term alcohol use can lead to dependency, making it harder to treat bipolar and other mood disorders.

Effects of Mixing Lithium and Alcohol

Healthcare professionals advise patients on lithium to avoid alcohol entirely. Those with alcohol use disorder who cannot abstain face a higher risk of experiencing the following adverse effects:

Dizziness
Impaired judgment
Difficulty concentrating
Nausea and vomiting
Stress, joint pain, and muscle aches
Fatigue and sluggishness

This lithium and alcohol reaction impairs motor function, elevates the risk of accidents, and disrupts normal sleep patterns. It also increases impulsivity and emotional instability—factors that heighten the risk of injury or death.

Alcohol use damages the liver and alters metabolic processes. Individuals who drink while taking lithium also face a significantly increased risk of suicidal behavior.

Lithium Toxicity

Lithium and alcohol both act as diuretics, increasing urination and causing dehydration. Dehydration raises the concentration of lithium in the blood, which can lead to lithium toxicity.

Symptoms of lithium toxicity may include:

Fainting or passing out
Confusion and hallucinations
Vomiting or diarrhea
Irregular heartbeat
Muscle weakness and numbness
Cold extremities
Seizures and vision issues

These symptoms require immediate medical attention. Lithium toxicity can be fatal if left untreated.

Hypothyroidism

When lithium and alcohol are consumed together in large amounts, they can interfere with thyroid function and cause hypothyroidism. This condition arises when the thyroid gland cannot produce sufficient hormones, resulting in a slowed metabolism.

Symptoms of hypothyroidism include:

Persistent fatigue
Numbness in hands
Weight gain
Depression
Elevated cholesterol levels

If left untreated, hypothyroidism can severely impact physical and emotional well-being. It is important to seek medical treatment early.
