Coming off lithium safely means doing it slowly and with your prescriber, never all at once. The pace matters because it changes how likely your illness is to come back, not just how you feel that week.1PubMed. Effects of the rate of discontinuing lithium maintenance treatment in bipolar disorders Many people stop for good reasons, such as side effects, kidney health, or pregnancy, and many manage it. The months afterward still need a safety plan, because the chance of a new mood episode stays high through the first year, and watching your mood closely for one to two years is wise.
How Slowly to Taper Off Lithium
A taper means lowering your dose in planned steps instead of stopping at once. UK guidelines advise reducing lithium over at least four weeks, ideally over up to three months.2Mind. Lithium and other mood stabilisers One prescribing guide suggests cutting the dose by 20 to 25% every two weeks or longer.3PubMed Central. Clinical use of lithium salts: guide for users and prescribers Someone on 1,000 mg a day might therefore drop about 200 to 250 mg at each step, taking eight to ten weeks in total.
In one survey of people tapering mood stabilizers, most tapered gradually and usually with a clinician’s help. Their tapers ranged from four weeks to several years.4Journal of Affective Disorders Reports. Patient experiences with tapering of mood stabilizers in self-reported bipolar spectrum disorder Liquid forms of some psychiatric drugs can make very small dose cuts easier than splitting tablets.5PubMed Central. A systematic review of manipulations to pharmaceutical dosage forms used in psychotropic tapering plans If the last steps feel hard, ask whether a lower-strength tablet or liquid lithium is available.
Before you begin, sit down with your prescriber and agree on the start date, the size of each step, and how long each step lasts. Pick a calm period, not a move, exam season, job change or new relationship. Decide in advance which signs mean pausing or going back up a step, and keep blood level and kidney checks going as your doctor advises. If symptoms appear, staying longer at your current dose is normal, not a failure, and the steps can get smaller toward the end instead of staying the same size.
Lithium comes in only a few tablet strengths, so your prescriber’s steps are partly set by which strengths can be combined to make each dose. That is why the plan should be a dated schedule, not a loose description. Ask for it on paper, with the dose for each date, so you and a family member can check that each day’s pills match. If you want to speed up or slow down because you feel fine or uneasy, call the prescriber first rather than changing course yourself, since they may adjust blood tests around the change.
Why Stopping Suddenly Raises Relapse Risk
After a fast stop, half of people had a new episode within about 4 months; after a gradual one, it took about 20 months.6PubMed. Effects of the rate of discontinuing lithium maintenance treatment in bipolar disorders In the first year, about 6.5% of people a month fell ill after a fast stop, versus 2.3% after a slow one. After that first year, the rates were similar.7PubMed. Effects of the rate of discontinuing lithium maintenance treatment in bipolar disorders About 37% of slow tapers stayed well for three years off lithium, compared with under 2% of fast stops.8PubMed. Effects of the rate of discontinuing lithium maintenance treatment in bipolar disorders Depression came back especially often after fast stops, at about five times the risk seen with a slow taper.9PubMed. Outcome after rapid vs gradual discontinuation of lithium treatment in bipolar disorders
Even a well-done taper carries risk. Across people stopping lithium, half had a new episode within about five months.10PubMed. Risk of recurrence following discontinuation of lithium treatment in bipolar disorder Mania tended to return early, often within a few months, while depression usually came later, often after a year.11PubMed. Risk of recurrence following discontinuation of lithium treatment in bipolar disorder People with more past mood episodes faced a higher risk of relapse after stopping.12PubMed. Risk of recurrence of bipolar disorder in pregnant and nonpregnant women after discontinuing lithium maintenance If your history is long or severe, you may want an especially slow taper and a strong backup plan.
A common mistake is stopping because you feel well. Feeling stable often means the medicine is working, not that it is unneeded. Relapse can take months to show, so early wellbeing is not proof of anything. Skipping doses on and off acts like a series of fast stops.
A reasonable backup plan often includes a named person who knows your early warning signs, a date for each check-in with your prescriber, and a clear step for what to do if symptoms return. If lithium is being stopped for a medical reason such as kidney damage or toxicity, you may still be right to stop; the question is usually how to stop safely and what to put in its place, so ask about both together.
What You May Feel While Coming Off
About 1 in 5 people who stopped lithium recalled a passing spell of anxiety, irritability or emotional ups and downs.13The British Journal of Psychiatry. Withdrawal Symptoms from Lithium: Four Case Reports and a Questionnaire Study These feelings can look like the start of a relapse, so report them rather than wait. You cannot reliably tell the two apart yourself, and the prescriber is the one to judge. A change that builds over several days and starts to affect sleep, work or relationships deserves a prompt call.
Early signs of mania include sleeping less without feeling tired, racing thoughts, faster speech, unusual spending or risk-taking, and irritability that feels new or stronger than usual. Early signs of depression include low mood, loss of interest, or pulling away from people for more than a few days, along with changes in sleep or appetite and trouble concentrating. Hopeless thoughts deserve an urgent call.
Suicidal acts were much more common in the first year after stopping lithium than during treatment.14PubMed. Lithium treatment and risk of suicidal behavior in bipolar disorder patients In one long-term review, suicide attempts rose about 20-fold in the first year off lithium, most after abrupt stops.15PubMed. Effects of lithium treatment and its discontinuation on suicidal behavior in bipolar manic-depressive disorders If thoughts of self-harm appear, tell your prescriber and someone close to you right away. In a crisis, call your local emergency number or a crisis line such as 988 in the US.
A daily mood and sleep log, on paper or an app, shows changes early. Share your warning signs with a trusted person who can notice them too.
Decide before the taper starts which symptoms mean a same-day call to your prescriber, and write down the clinic’s after-hours number so you are not searching for it when unwell. Give a trusted person permission in advance to contact your prescriber if they see worrying changes, because people in the early stage of mania often do not notice it themselves.
Switching From Lithium to Another Mood Stabilizer
Switching usually uses a cross-taper: you start the new medicine before lithium is gone, so you are never left without protection.16The Carlat Report. Mood Stabilizers and Anticonvulsants For a switch to valproate, lithium is typically cut in steps over about two weeks as valproate rises.17Medscape. Therapeutic Switching in Bipolar Disorder: An Expert Interview With Trisha Suppes, MD, PhD In one example, 1,500 mg of lithium drops by 300 mg every three days until it stops on about day 16.18The Carlat Report. Mood Stabilizers and Anticonvulsants
Lamotrigine is different. It has to be raised very slowly to avoid a serious rash, taking about four weeks to reach a typical dose, so lithium usually stays near full dose for about a month before its taper begins.19The Carlat Report. Mood Stabilizers and Anticonvulsants
For a while you take two medicines, so side effects from either are possible, and blood tests may check levels of both. Strong side effects or a medical problem can justify a faster switch, decided by your doctor.
On the lamotrigine route, do not skip ahead on doses to make up for a slow start, since faster increases are what raise the chance of a serious rash. If you miss several days of lamotrigine, ask your prescriber before restarting at your old dose, as the schedule may need to be repeated from a lower step.
Most rashes on lamotrigine turn out to be harmless, but you cannot reliably tell a dangerous one by looking, so report any new rash the same day. If a rash comes with fever, mouth sores, blistering or swollen glands, seek urgent care rather than waiting for an appointment.
Coming Off Lithium Before or During Pregnancy
Lithium can affect the baby’s heart, which forms about 4 to 8 weeks after conception.20MGH Center for Women’s Mental Health. Lithium Discontinuation While Attempting to Conceive Some specialists therefore suggest staying on lithium while trying to conceive and tapering once pregnancy is confirmed, before that window.21MGH Center for Women’s Mental Health. Lithium Discontinuation While Attempting to Conceive The reason is that the longer you are off lithium while trying, the higher the relapse risk.22MGH Center for Women’s Mental Health. Lithium Discontinuation While Attempting to Conceive People with very severe illness may choose to stay on lithium through early pregnancy despite the risk.23MGH Center for Women’s Mental Health. Lithium Discontinuation While Attempting to Conceive
Timing is the hard part. Stopping before conception removes the drug’s risk to the heart but exposes you to relapse for as long as it takes to become pregnant, which can be months. The best choice depends on how severe your past episodes were, how quickly you tend to relapse, and how long conception may take.
About half of women relapsed within 40 weeks of stopping, pregnant or not.24PubMed. Risk of recurrence of bipolar disorder in pregnant and nonpregnant women after discontinuing lithium maintenance Among women who stayed well through pregnancy, 70% had an episode after birth.25PubMed. Risk of recurrence of bipolar disorder in pregnant and nonpregnant women after discontinuing lithium maintenance Plan postpartum support and monitoring before the baby arrives.
See your psychiatrist before trying to conceive, not after a positive test. Ask about a perinatal psychiatrist or specialist team, and discuss whether to restart a medicine after birth and how it fits with breastfeeding.
Stopping once pregnancy is confirmed means a fast timeline, so ask in advance how quickly you can safely come down and what monitoring you will have in that window. Some people instead move to a different medicine before conceiving; ask what the alternatives would mean for the baby, since not all are safer. Never stop lithium abruptly on seeing a positive test, because a sudden stop is the highest-risk way to come off.
Stopping Lithium Because of Kidney Problems
Your blood results may list eGFR, an estimate of how well your kidneys filter.26PubMed. Renal function after withdrawal of lithium After stopping lithium, the decline in eGFR usually slowed, and the effect lasted at least five years.27PubMed Central. Kidney function decline improves after lithium discontinuation People with lower kidney function when they stopped tended to benefit most.28PubMed Central. Kidney function decline improves after lithium discontinuation Some with very low function, an eGFR around 32, kept declining.29PubMed. Renal function after withdrawal of lithium Rising kidney test values were among the most common side effects leading people to stop.30PubMed Central. Reasons for lithium discontinuation in men and women with bipolar disorder: a retrospective cohort study
A single reading can vary, so your doctor will usually look at the trend across several tests. Stopping may slow further decline but does not necessarily restore function already lost, so the aim is protecting what remains.
Keep having kidney blood tests after stopping to see the trend. Kidneys clear lithium, so weaker kidneys can push blood levels up, and dose changes need checks. Ask whether a kidney specialist should be involved. Replacing lithium with another mood stabilizer usually needs planning, not a gap.
Kidney protection has to be balanced against the risk of mood episodes. A mild fall in your kidney filtering score does not always mean you should stop, while a steady decline often does. Ask your doctor what level or rate of change would change their advice, so you know what you are watching for.
Will Lithium Work Again If You Restart
On average about 17% of people restarting lithium did not respond as well as before.31PubMed Central. Lithium-discontinuation-induced treatment refractoriness revisited This was more likely after a faster taper, a longer time off, or many years on lithium.32PubMed Central. Lithium-discontinuation-induced treatment refractoriness revisited Stopping slowly may help keep lithium as an option for later.
Responding less well means the illness may be harder to control at the same dose, not that lithium has become unsafe. Your doctor can adjust the dose or add another medicine.
Make a restart plan in advance. Agree with your doctor on which signs mean restarting, and know who to call and how fast an appointment can happen. Restarting early, at the first warning signs, tends to be simpler than in a full episode.
Support That Helps While You Come Off
Many people consider stopping because they dislike the idea that medicine controls their moods or that they have a long-term illness.33PubMed. Do clinicians understand why individuals stop taking lithium? Talking these feelings through with a therapist can help, whatever you decide. Therapy such as cognitive behavioral therapy can help manage psychological symptoms while coming off.34Talkspace. Lithium Withdrawal: Symptoms, Timeline & Coping Therapies that teach you to track mood and sleep, spot early signs and plan responses suit a taper well, so ask a therapist whether they have experience with bipolar disorder. Therapy can also start before the taper begins, which gives you time to build skills while you are still stable.
Expert guidelines for caregivers stress learning the illness and its warning signs and looking after themselves too.35PubMed Central. Development of guidelines for caregivers of people with bipolar disorder: a Delphi expert consensus study A family member can learn your early warning signs ahead of time, agree with you on how to raise concerns without arguing, and know the crisis plan and who to contact. They can also ask the prescriber how to respond if they think a relapse is starting, so they are not guessing. A relative who is exhausted or anxious is less able to notice early signs, so they need their own support, such as a friend, a support group or their own doctor.
Daily habits protect mood as well. Keep regular sleep and wake times, since lost sleep can trigger mania. Limit alcohol and avoid recreational drugs during and after the taper, keep a steady routine, and reduce major stress where you can.
