Lithium helps reduce the severity and frequency of mania — the elevated, euphoric end of the mood scale — and may help to treat bipolar depression. If you have been at risk of suicide, lithium may help reduce these feelings. Lithium also helps prevent manic and depressive episodes occurring in the future.
At a neuronal level, lithium reduces excitatory (dopamine and glutamate) but increases inhibitory (GABA) neurotransmission; however, these broad effects are underpinned by complex neurotransmitter systems that strive to achieve homeostasis by way of compensatory changes.
Lithium stands out for its preventative effects in bipolar disorder, but it also has important benefits outside of the manic-depressive symptom lists. It is the only mood stabilizer that significantly reduces the risk of suicide, and it reduces mortality in other ways as well.
The most common side effects of lithium are feeling or being sick, diarrhoea, a dry mouth and a metallic taste in the mouth. Your doctor will carry out regular blood tests to check how much lithium is in your blood.
It is not known how lithium works to stabilize a person's mood. However, it does act on the central nervous system. It helps you to have more control over your emotions and helps you cope better with the problems of living. It is important that you and your family understand all the effects of this medicine.
Furthermore, in a study done by Schou, all three patients that were given dosages of lithium all appeared emotionally flattened to their families, as if the drug had had a “blunting effect” on their personalities.
When first starting lithium, many people experience common side effects, such as nausea, shakiness, or greater thirst. Regular blood monitoring is important to make sure you are taking a safe and effective dose of lithium.
Lithium might increase a brain chemical called serotonin. Some medications also have this effect. Taking lithium along with these medications might increase serotonin too much. This might cause serious side effects including heart problems, seizures, and vomiting.
Symptoms of lithium toxicity include severe nausea and vomiting, severe hand tremors, confusion, and vision changes.
Neurotransmitter Regulation: Lithium increases the activity of calming GABA receptors and decreases the activity of more stimulating dopamine and NMDA receptors, resulting in an overall relaxing, stabilizing effect.
Long-term lithium treatment is more effective than second-generation antipsychotics. For the majority of patients, the side effect profile of lithium carries less risk than the use of second generation antipsychotic medications.
Lithium has been the treatment of choice for patients with bipolar disorder (BD) for nearly 70 years. It is recommended by all relevant guidelines as a first-line treatment for maintenance therapy.
Such studies found that long-term risk of new manic or depressive episodes was lower with lithium than with placebo, although the benefit was greater against new episodes of mania than of depression.
If you have bipolar disorder, you may be offered lithium for a longer period, to prevent or reduce your risk of relapse. Your doctor may suggest that you commit to taking lithium for at least six months, possibly longer. This is because it can take some time to make sure the medication is working effectively.
It takes about 1 to 3 weeks for lithium to show the effects and remission of symptoms. Many patients show only a partial reduction of symptoms, and some may be nonresponders. In cases where the patient does not display an adequate response, consider monitoring plasma levels, and titrating the dose.
If you suddenly stop taking lithium, one of the drugs most commonly prescribed to stabilize bipolar disorder moods, you can experience “rebound,” a worsening of your bipolar symptoms.
In 62% of episodes, lithium was discontinued due to adverse effects, in 44% due to psychiatric reasons, and in 12% due to physical reasons interfering with lithium treatment.
Much of the information available says that—once you are diagnosed with bipolar disorder—you will have to take medication for the rest of your life. Most commonly included medications are Lithium, mood stabilizers, and antipsychotics.
Research has shown that in some bipolar patients, weight gain occurs with lithium monotherapy because lithium alters their taste. This side effect causes cravings for beverages and food that are salty, fatty, or sugary.
Excessive urination and thirst (polyuria and polydipsia) are consistently found to be among the most common side effects associated with lithium with rates up to 70% in long-term patients (Bone et al.
Results: Long-term lithium treatment is associated with a reduced urinary concentrating ability, with subsequent polyuria and polidypsia and nephrogenic diabetes insipidus (in 10-40% of patients).
Take your lithium each night at the same time. You need to take it at night because blood tests need to be done during the day, 12 hours after a dose (see Section 4 'Blood tests after starting to take lithium').
While other medications might work better for some people, lithium remains a common form of treatment for stabilizing manic episodes, characterized by racing thoughts, grandiosity, decreased need for sleep, and hallucinations, says Shayla Sullivant, MD, a child and adolescent psychiatrist at Children's Mercy Hospital ...
Approximately 25% of people gain weight from taking lithium, according to a review article published in Acta Psychiatrica Scandinavica. 1 After analyzing all relevant published medical studies, the authors reported an average weight gain of 10 to 26 pounds among those who experience this troubling side effect.
There are cases when suicidal thoughts or bipolar tendencies become temporarily, or permanently, worse when you start taking lithium. If you feel that your symptoms are worsening, call the doctor who prescribed lithium to you and discuss your options.
