Lithium Therapy
What is Lithium Therapy?
Lithium therapy is a treatment that uses lithium salts to manage bipolar disorder and other mood conditions. Lithium helps stabilize mood swings by affecting chemical signals in the brain. It prevents both the extreme highs of mania and the devastating lows of depression.
This medication has been used for over 70 years and remains one of the most effective treatments for bipolar disorder. Lithium requires careful monitoring because the difference between a therapeutic dose and a toxic dose is small. Regular blood tests help doctors keep lithium levels in the safe and effective range.
People on lithium therapy need ongoing medical supervision to balance benefits and risks. The medication affects multiple body systems including the kidneys, thyroid, and blood. Proper monitoring ensures the treatment works safely over months and years.
Symptoms
- Increased thirst and urination, especially in the first few weeks
- Fine hand tremor that may worsen with higher doses
- Mild nausea or stomach upset when starting treatment
- Weight gain over time, usually 5 to 10 pounds
- Drowsiness or fatigue, particularly during dose adjustments
- Metallic taste in the mouth
- Memory problems or difficulty concentrating
- Skin changes including acne or psoriasis
- Muscle weakness or coordination issues
- Thyroid changes that may cause fatigue or weight changes
Some people tolerate lithium well with minimal side effects. Others experience more noticeable symptoms that improve as their body adjusts. Severe symptoms like confusion, severe tremor, or slurred speech may signal dangerous lithium levels and require immediate medical attention.

Causes and risk factors
Lithium therapy is prescribed to treat bipolar disorder, a condition that causes extreme mood swings between mania and depression. Doctors may also prescribe lithium for major depression that does not respond to other treatments. Some people receive lithium to prevent suicide in high-risk situations or to treat certain types of severe headaches.
The need for lithium therapy comes from brain chemistry imbalances, not from patient choices or behaviors. Bipolar disorder has strong genetic components and often runs in families. Stress, trauma, and major life changes can trigger episodes but do not cause the underlying condition. Lithium works by changing how brain cells respond to certain neurotransmitters, which helps restore more stable moods over time.
How it's diagnosed
Doctors diagnose the need for lithium therapy based on mental health symptoms and psychiatric evaluation. Before starting lithium, patients need baseline blood tests to check kidney function, thyroid function, and blood cell counts. These tests establish a starting point for comparison during treatment.
Once lithium therapy begins, regular blood monitoring becomes essential for safe treatment. Rite Aid offers testing through Quest Diagnostics locations nationwide to track white blood cell count and other important markers. Blood tests typically happen every few months to ensure lithium levels stay therapeutic without becoming toxic. Your doctor will also monitor kidney function and thyroid health throughout treatment.
Treatment options
- Taking lithium exactly as prescribed, at the same times each day
- Drinking 8 to 12 glasses of water daily to prevent dehydration
- Maintaining consistent salt intake, as sodium affects lithium levels
- Avoiding sudden changes in diet, especially low-salt diets
- Getting regular blood tests to monitor lithium levels and organ function
- Limiting caffeine and alcohol, which can affect hydration and mood
- Staying active with regular exercise to manage weight and mood
- Getting adequate sleep on a consistent schedule
- Informing all doctors and dentists about lithium use before procedures
- Watching for signs of toxicity like severe tremor, confusion, or vomiting

Frequently asked questions
Lithium causes a predictable increase in white blood cell count called leukocytosis. This is a normal effect of the medication, not a sign of infection. Regular monitoring helps doctors tell the difference between therapeutic changes and actual infections. Tracking white blood cell count also helps detect potential lithium toxicity.
Most people need blood tests every 3 to 6 months once lithium levels are stable. You may need more frequent testing when first starting lithium or after dose changes. Your doctor will also check kidney and thyroid function regularly. Testing frequency depends on your age, dose, and how long you have been on lithium.
Early signs include severe hand tremor, diarrhea, vomiting, and confusion. You may also notice slurred speech, extreme drowsiness, or muscle twitching. These symptoms require immediate medical attention. Dehydration, illness, or medication changes can raise lithium levels into the toxic range quickly.
Yes, but keep your caffeine intake consistent from day to day. Caffeine is a diuretic that increases urination and can affect hydration. Sudden increases or decreases in caffeine may change lithium levels. Drink plenty of water to stay well hydrated regardless of caffeine consumption.
Long-term lithium use can affect kidney function in some people. Regular monitoring helps catch changes early before permanent damage occurs. Most people on lithium maintain healthy kidney function with proper hydration and monitoring. Your doctor may adjust your dose or suggest alternatives if kidney problems develop.
Lithium can increase appetite and cause water retention. It may also slow metabolism slightly in some people. The average weight gain is 5 to 10 pounds, though this varies widely. Regular exercise, mindful eating, and staying hydrated can help manage weight during lithium therapy.
No, stopping lithium suddenly is dangerous and can trigger severe mood episodes. Bipolar disorder requires ongoing treatment even when symptoms improve. Many people who stop lithium experience relapse within months. Always talk to your doctor before making any changes to your lithium therapy.
Dehydration can cause lithium levels to rise quickly into the toxic range. This creates a medical emergency requiring immediate care. Drink extra water during hot weather, exercise, or illness. Call your doctor if you have vomiting, diarrhea, or fever while taking lithium.
Yes, ibuprofen and similar drugs called NSAIDs can raise lithium levels. This increases the risk of toxicity. Acetaminophen is usually safer for pain relief while on lithium. Always check with your doctor or pharmacist before taking any new medication, including over-the-counter drugs.
Lithium typically takes 1 to 2 weeks to start stabilizing mood. Full benefits may take 6 to 12 months of consistent use. Many people notice reduced frequency and severity of mood episodes over time. Patience and regular monitoring are essential for successful lithium therapy.
