Pharmacist tips for Lithium
- You can take lithium with or without food, but nausea and vomiting are common side effects of lithium. Taking it with food can help. But if it doesn't and these effects are bothersome, let your provider know because you might need to have your dose lowered, your nausea treated, or switched to lithium (Lithobid) extended-release tablets.
- Lithium can make you sleepy and dizzy. Don't drive or do anything requiring concentration until you know how this medication affects you. Also, drinking alcohol isn't recommended while taking lithium because it can worsen sleepiness and dizziness.
- Stomach upset that won’t go away, shakiness, slurred speech, and extreme drowsiness can be signs that your lithium dose is too high. If you experience these symptoms, call your provider or get medical help right away.
- The amount of fluids and salt in your diet can affect your lithium blood levels. Avoid becoming overheated or dehydrated in hot weather or during exercise, and keep your salt intake consistent. Also, make sure to stay well-hydrated and drink fluids when you feel thirsty. Changing the amount of salt in your diet can change the lithium levels in your blood and cause more side effects. Too little salt can cause higher blood lithium levels, while too much salt can cause your lithium levels to fall. Talk to your healthcare provider about how much fluids you should drink when taking lithium.
- Lithium can interact with a lot of commonly used medications. such as NSAIDs like ibuprofen (Advil, Motrin) or naproxen (Aleve), blood pressure medications, and diuretics (water pills). Make sure to tell your provider and pharmacist about all of the medications you're taking before starting lithium. Also, don't start any new medications while taking lithium without talking to your provider first.
- Swallow the extended-release tablets whole. Don't crush or chew them as too much medication might get released at once, which can cause side effects.
- If you're taking the liquid form of lithium, be sure to use the measuring device that your pharmacy provides with the medication. Don't use household spoons to measure out your dose because they might not be accurate and you can give yourself the wrong dose.
- Don't change your dose or suddenly stop taking lithium without talking to your provider first. If you're interested in stopping the medication, contact your provider. They'll give you specific instructions on how to lower your dose slowly over a period of time before completely stopping the medication.

Risks and warnings for Lithium
Lithium can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Lithium toxicity
- Risk factors: Body fluids or electrolyte levels not in balance | Current fever or illness | Kidney problems | Heart problems
If your blood lithium levels are too high, you can experience lithium toxicity, which can cause serious side effects. Your risk is higher if you're taking medications that can raise the levels of lithium in your body. To prevent lithium toxicity, your provider will measure lithium levels regularly to see if you're within a safe range, and adjust the dose of your medication as needed. Get medical help right away if you're experiencing symptoms of having too much lithium in your body, such as diarrhea, vomiting, abnormal eye movements, shaking, muscle weakness, impaired speech, loss of balance or coordination, confusion, and trouble breathing.
Kidney problems
- Risk factors: Long-term use | Kidney problems
Lithium can directly damage your kidneys, which could potentially be reversed if you stop taking lithium. Lithium can also affect your kidneys' ability to balance salt and water in your body. When first starting treatment or after long-term use, you might experience more frequent urination and more thirst. It is important that you keep your fluid and salt intake relatively the same each day. You should also avoid dehydration and becoming overheated in hot weather and exercise. Your provider will monitor your kidney health before and during treatment and will adjust or stop your dose of lithium if there's evidence the medication is damaging your kidneys. Contact your provider if you notice bloody or foamy urine, lower back pain, or fatigue, because these could be signs of damaged kidneys.
Serotonin syndrome
- Risk factors: Taking other medications that raise serotonin levels in your brain
Some people taking lithium have developed a rare, but potentially life-threatening condition called serotonin syndrome. This condition happens where there's too much serotonin in the brain. Your risk for serotonin syndrome is higher if you use lithium with other medications that can raise your serotonin levels, such as certain antidepressants, mental health medications, pain medications, and migraine medications. Let your provider know about all the medications you take before starting lithium. Also, don't start any new medications without talking to your provider first. Symptoms of serotonin syndrome include fast heart rate, sweating, muscle stiffness or spasms, fever, and confusion. Get medical help right away if you have any of these symptoms.
Thyroid problems
- Risk factors: Long-term use | Thyroid problems
Lithium can build up in the thyroid and lead to thyroid problems such as hypothyroidism (low thyroid hormone) or hyperthyroidism (overactive thyroid). Your provider will monitor your thyroid health before and during treatment to make sure your thyroid gland is working properly and your thyroid hormone levels are normal. If you get symptoms of hypothyroidism (e.g., tiredness, weight gain, and feeling cold, contact your provider right away) or hyperthyroidism (e.g., weight loss, feeling hot, irritable, sweating), contact your provider.
Heart problems (Brugada syndrome)
- Risk factors: Personal or family history of Brugada syndrome | Family history of sudden death before the age of 45 | Unexplained fainting
Lithium can worsen the symptoms of a rare but life-threatening heart rhythm condition called Brugada syndrome. Lithium should be avoided in patients with Brugada syndrome or those suspected of having Brugada syndrome. People with a family history of Brugada syndrome or sudden death before the age of 45 years should consult with a heart specialist (cardiologist) to discuss the benefits and risks of starting lithium treatment.
Low blood sodium levels
- Risk factors: Older adults | Taking a water pill | Not enough body fluids | Currently sick with illness | Drinking alcohol regularly
Lithium can cause low sodium levels in your blood. Your provider might closely monitor your blood sodium levels before and during treatment with lithium. Get medical help right away if you experience weakness, confusion, difficulty concentrating, headache, or memory problems because these could be signs of low blood sodium levels, which is a medical emergency.
High blood calcium levels and high parathyroid hormone levels
- Risk factors: Long-term use | Taking other medications that raise blood calcium levels
Taking lithium for a long time can raise the calcium levels in your blood due to too much parathyroid hormone. Sometimes, these changes in your parathyroid glands won't go away and the only way to fix it is through surgery. Your provider will monitor your blood calcium levels and parathyroid hormone levels during treatment to make sure your parathyroid gland is working properly and that your calcium levels are normal. Let your provider know if you have symptoms of high calcium levels, such as tiredness, muscle weakness, loss of appetite, nausea, vomiting, constipation, and confusion.
Brain-related side effects
- Risk factors: Taking an antipsychotic and lithium together
Taking lithium with antipsychotics such as quetiapine (Seroquel), aripiprazole (Abilify), and olanzapine (Zyprexa) can raise your risk for certain brain side effects, such as weakness, fever, tremors, confusion, and muscle stiffness. If you notice any of these symptoms, get medical help right away.
Though very rare, taking lithium can also raise the pressure in the brain. Let your provider know right away if you notice changes in your vision. If this change is caused by lithium, then they'll need to switch you to a different medication.
