Dosage Forms and Strengths of Lithium
Lithium is available in several forms and strengths to accommodate different treatment needs. Below are the common dosage forms:
- Capsules: 150 mg, 300 mg, 600 mg
- Tablets: 300 mg
- Extended-release tablets: 300 mg, 450 mg

Contraindications for Lithium Treatment
A contraindication is a specific condition or situation where a medication should not be used because it may cause harm. If you have any of the conditions listed below, Lithium may not be safe for you. Always consult your healthcare provider before starting or stopping any medication.
- Severe kidney disease: Lithium is processed by the kidneys, and if you have severe kidney disease, your body may not clear the medication properly, leading to toxic levels.
- Severe heart disease: Lithium can affect the heart’s electrical activity, and in people with heart disease, it may increase the risk of arrhythmias (irregular heartbeats).
- Dehydration or low sodium levels: Lithium levels in the blood can rise dangerously if you are dehydrated or have low sodium levels, which can lead to toxicity. This is because Lithium and sodium are processed similarly by the kidneys.
- Allergy to Lithium: If you have had an allergic reaction to Lithium in the past, you should not take it again, as this could lead to a serious allergic reaction.
Drug-to-Drug Interactions with Lithium
Some medications can interact with Lithium, either increasing its levels in the blood (which can lead to toxicity) or reducing its effectiveness. It’s important to inform your healthcare provider of all medications you are taking, including over-the-counter drugs and supplements. Below are some common medications that may interact with Lithium:
- Diuretics (water pills): Medications like hydrochlorothiazide (Microzide) can increase Lithium levels in the blood, leading to toxicity.
- Nonsteroidal anti-inflammatory drugs (NSAIDs): Medications like ibuprofen (Advil, Motrin) or naproxen (Aleve) can increase Lithium levels by reducing kidney function.
- ACE inhibitors: Medications like lisinopril (Zestril, Prinivil) or enalapril (Vasotec) can increase Lithium levels by affecting kidney function.
- Antidepressants: Some antidepressants, such as fluoxetine (Prozac) or sertraline (Zoloft), may increase the risk of serotonin syndrome when taken with Lithium.
- Antipsychotics: Medications like haloperidol (Haldol) or risperidone (Risperdal) can increase the risk of neurotoxicity when combined with Lithium.
Lithium in Pregnancy
Is it safe to take Lithium medication during pregnancy?
Taking Lithium during pregnancy, particularly in the first trimester, may increase the risk of birth defects, especially heart-related issues in the baby. However, untreated bipolar disorder or other mental health conditions can also pose significant risks to both the mother and the baby. If you are pregnant or planning to become pregnant, it’s essential to have a detailed discussion with your healthcare provider about the risks and benefits of continuing Lithium treatment. In some cases, your provider may adjust your Lithium dosage or explore alternative treatment options to ensure the best outcome for both you and your baby.
Lithium while Breastfeeding
Is it safe to take Lithium while breastfeeding?
Breastfeeding while taking Lithium is generally not recommended, as Lithium can pass into breast milk and may affect the baby. If you are considering breastfeeding, it’s important to consult your healthcare provider to carefully weigh the potential risks and benefits. In some situations, alternative medications may be safer for both you and your child.
Estimated Cost of Lithium Medication
The cost of a 30-day supply of Lithium without insurance can vary depending on the dosage and the pharmacy. With a GoodRx coupon, the estimated price for a 30-day supply of generic Lithium carbonate (300 mg) typically ranges from $10 to $20. Prices may fluctuate, so it’s a good idea to check with your local pharmacy or use a discount service like GoodRx to find the most affordable option.
Possible Alternatives to Lithium Treatment
If Lithium treatment isn’t suitable for you, there are other options available depending on your specific condition. Below are some alternatives for conditions commonly treated with Lithium. Always consult your healthcare provider before making any changes to your treatment plan. You may also consider scheduling a telemedicine visit with one of our providers to explore your options further.
Bipolar Disorder Treatment Options
Alternatives include mood stabilizers such as valproate (Depakote) or lamotrigine (Lamictal), as well as antipsychotic medications like quetiapine (Seroquel). Additionally, lifestyle changes, such as maintaining a regular sleep schedule and managing stress, can help control symptoms.
Major Depressive Disorder
Antidepressants like sertraline (Zoloft) or escitalopram (Lexapro) may be prescribed. Cognitive-behavioral therapy (CBT) and regular physical activity can also be effective in managing symptoms.
Schizoaffective Disorder
Common treatments include antipsychotic medications such as risperidone (Risperdal) or aripiprazole (Abilify). Psychotherapy and strong social support are also key components of managing this condition.
Depression
Selective serotonin reuptake inhibitors (SSRIs) like fluoxetine (Prozac) or serotonin-norepinephrine reuptake inhibitors (SNRIs) like venlafaxine (Effexor) are often used as alternatives. Therapy and lifestyle modifications, such as regular exercise, can also play a significant role in treatment.
Mania
Antipsychotics like olanzapine (Zyprexa) or mood stabilizers such as valproate (Depakote) may be considered as alternatives to Lithium for managing mania.
Hypomania
Similar to mania, mood stabilizers like lamotrigine (Lamictal) or antipsychotics such as quetiapine (Seroquel) may be recommended.
Cluster Headaches
Alternatives include verapamil, a calcium channel blocker, or corticosteroids. Lifestyle changes, such as avoiding alcohol and smoking, can also help reduce the frequency of headaches.
Borderline Personality Disorder
While Lithium is sometimes used, psychotherapy—particularly dialectical behavior therapy (DBT)—is considered the most effective treatment. Medications like mood stabilizers or antidepressants may also be part of the treatment plan.
Post-Traumatic Stress Disorder (PTSD)
Antidepressants such as sertraline (Zoloft) or paroxetine (Paxil) are commonly prescribed. Therapy, especially trauma-focused therapy, is also a critical part of treatment for PTSD.
Intermittent Explosive Disorder
Antidepressants like fluoxetine (Prozac) or mood stabilizers such as divalproex (Depakote) may be used. Cognitive-behavioral therapy (CBT) can also help manage anger and impulsivity associated with this condition.
Recent Updates on Lithium Research
Recent studies on Lithium continue to explore its neuroprotective properties and potential benefits beyond mood stabilization. Some research suggests that Lithium may offer protective effects against neurodegenerative diseases like Alzheimer’s and Parkinson’s, though more studies are needed to confirm these findings. Additionally, researchers are investigating whether lower doses of Lithium could effectively treat mood disorders while reducing side effects. Ongoing clinical trials are also examining the use of Lithium in combination with other medications to enhance its effectiveness in treatment-resistant depression and bipolar disorder.
As new research emerges, staying informed is essential. Be sure to discuss any potential changes to your treatment plan with your healthcare provider. If you have questions about Lithium or are considering alternative treatments, schedule a telemedicine visit with one of our providers today to receive personalized advice and support.
