• Take at the same times each day.
• Do not crush or split unless your product instructions say you can.
• Swallow whole with water.
• Continue regularly even when you feel better—stopping suddenly can increase the risk of mood relapse.

When to expect benefit

• Early period: Some people notice mood changes within days to two weeks, but it can take longer.
• Maintenance benefit: Stabilisation is usually more evident over weeks to months.

Missed dose guidance (general)

If you miss a dose, take it when you remember unless it is close to your next dose. Do not take a double dose to make up for it. If you are unsure, check your specific product instructions or ask your pharmacist.

Food interactions

Food can affect lithium indirectly by changing fluid intake, salt intake, and hydration. In general, lithium can be taken with or without food, but consistency matters.

• Maintain consistent salt and fluid intake day to day.
• Avoid large dietary changes (for example, sudden low-salt diets) unless directed by your clinician.
• Stay hydrated, especially during hot weather, exercise, or illness.
• If you experience vomiting or diarrhoea, seek advice promptly—dehydration may raise lithium levels.

If your healthcare professional recommends a specific diet plan (including salt changes), it should be accompanied by lithium level monitoring.

Alcohol and medicine interactions

Alcohol

Alcohol may worsen mood instability and can also affect hydration and kidney function. In addition, alcohol may mask early symptoms of lithium side effects (such as dizziness or nausea).

• Use caution or avoid heavy drinking.
• Hydrate and avoid becoming dehydrated.
• If you notice symptoms such as severe nausea, tremor, confusion, or unsteadiness, seek medical advice urgently.

Important medicine interactions

Lithium interacts with several commonly used medicines. Some interactions increase lithium levels (raising toxicity risk), while others can reduce lithium effectiveness or alter kidney handling of lithium.

Tell your pharmacist and healthcare professional about all medicines you take, including over-the-counter products and herbal supplements.

• Non-steroidal anti-inflammatory drugs (NSAIDs) (e.g., ibuprofen, naproxen, diclofenac) — may increase lithium levels in many people.
• ACE inhibitors and ARBs (used for blood pressure/heart failure) — may increase lithium levels.
• Diuretics (especially thiazides) — can significantly raise lithium levels.
• Some antibiotics (certain types) — can affect levels depending on the situation.
• Other mood medicines — combination may be appropriate, but requires monitoring for side effects and kidney/thyroid effects.
• Serotonergic medicines — combining with other drugs may increase risk of side effects in certain situations; discuss with your clinician.
• Dehydration risk medicines — anything that causes fluid loss can increase lithium concentration indirectly.

This is not a complete list. Your pharmacist can check specific interactions for your exact medicines.

Dosing (general information)

Lithium dosing is highly individual. The dose is usually adjusted based on:

• Lithium blood levels (measured via blood test)
• Kidney function (creatinine/eGFR)
• Age and body water balance
• Other medicines and overall health

Because safe and effective levels are close to toxic levels, dose changes should never be self-directed. Your prescriber may schedule blood tests after starting treatment and after each dose adjustment.

Typical target blood levels (general)

Target ranges vary by indication and local clinical guidance. Your clinician will determine your personal range and monitoring schedule.

How dosing schedules often look in practice

• Start low and adjust slowly to reduce the risk of side effects.
• Extended-release formulations are designed to reduce peak-trough swings, but monitoring remains essential.
• Regular monitoring helps ensure levels stay within the intended therapeutic window.

If your blood tests show levels are too high or too low, your dose may be changed and retested.

Safety profile and warning signs

Key safety points

• Narrow therapeutic index: Lithium is effective at certain levels, but toxicity risk increases if levels rise.
• Kidney and thyroid monitoring: Lithium can affect the kidneys and thyroid, so periodic blood tests are usually recommended.
• Dehydration risk: Lithium levels can increase with dehydration.

Common side effects

Some side effects may occur early, and often improve with dose adjustment and careful monitoring.

• Thirst and increased urination
• Tremor (shakiness), especially with higher levels
• Mild nausea or stomach discomfort
• Fatigue or sleep changes
• Weight changes in some people

Serious symptoms to seek urgent advice for

Contact your healthcare provider urgently (or emergency services if severe) if you experience signs that may suggest lithium toxicity. These can include:

• Severe or worsening vomiting and diarrhoea
• Confusion, unusual drowsiness, or severe dizziness
• Loss of coordination or trouble walking
• Marked tremor or muscle twitching
• Slurred speech
• Fainting

Toxicity risk is higher with dehydration, drug interactions, kidney impairment, or rapid dose increases.

Pregnancy and breastfeeding (general considerations)

Lithium use during pregnancy and breastfeeding requires specialist discussion due to potential risks and the need for careful monitoring. If you are planning pregnancy, are pregnant, or breastfeeding, talk to your healthcare team promptly to discuss benefits and risks and suitable monitoring.

Practical use tips (how to use Lithobid safely)

1) Keep up with blood test monitoring

Monitoring is a cornerstone of lithium safety. Your clinician may check:

• Lithium levels (to confirm dose is in range)
• Kidney function
• Thyroid function
• Sometimes electrolytes depending on your health and other medicines

2) Stay hydrated and manage illness early

• Drink adequate fluids daily.
• Avoid overheating (especially during summer or in gyms/saunas).
• If you have fever, vomiting, or diarrhoea, seek advice promptly. You may need blood tests or temporary dose changes.

3) Keep salt intake consistent

Sudden changes in salt intake can influence lithium levels. If you start a low-salt diet for blood pressure or other reasons, make sure your clinician is aware so levels can be checked.

4) Review medicines every time

• Before starting a new medication, ask the pharmacist to check interactions.
• Be careful with NSAIDs for pain and diuretics for fluid retention.
• Tell your clinician about supplements and herbal products as well.

5) Don’t stop abruptly

Stopping lithium suddenly can increase the risk of mood relapse. If changes are needed, it should be done under medical supervision with a monitoring plan.

Alternative options

Lithium is one option for bipolar disorder and related mood stabilisation. Depending on your symptoms, history, and health profile, clinicians may consider other medicines or strategies. Alternatives can include:

• Other mood stabilisers (for example, certain anticonvulsants used in mood disorders)
• Antipsychotic medicines used for bipolar mania or maintenance in some cases
• Psychological therapies such as structured psychotherapy and relapse-prevention plans
• Lifestyle supports including sleep regularity, stress management, and substance avoidance

The “best” alternative depends on your condition, side-effect tolerance, kidney/thyroid status, and prior response. If you’re considering switching from lithium, discuss it with your clinician rather than stopping on your own.
