ACE inhibitors, (for example, enalapril [Vasotec], lisinopril [Zestril, Prinivil], benazepril [Lotensin], quinapril [Accupril], moexipril [Univasc], captopril [Capoten], ramipril [Altace]), may increase the risk of developing lithium toxicity by increasing the amount of lithium that is reabsorbed into the body in the tubules of the kidney and thereby reducing the excretion of lithium.

When carbamazepine (Tegretol) and lithium are used together, some patients may experience side effects, including dizziness, lethargy, and tremor. Central nervous system side effects also may occur when lithium is used with antidepressants, (for example, fluoxetine [Prozac] sertraline [Zoloft], and paroxetine [Paxil], fluvoxamine [Luvox], amitriptyline [Elavil], imipramine [Tofranil], desipramine [Norpramin]). Combining lithium with monoamine oxidase inhibitor (MAOI) class of antidepressants (for example, isocarboxazid [Marplan], phenelzine [Nardil], tranylcypromine [Parnate], selegiline [Eldepryl], and procarbazine [Matulane]) or other drugs that inhibit monoamine oxidase (for example, linezolid [Zyvox]) may lead to serious reactions.

Medications which cause the urine to become alkaline (the opposite of acidic) can increase the amount of lithium that is lost into the urine. This results in lower blood concentrations of lithium and reduces the effects of lithium. Such drugs include potassium acetate, potassium citrate (Urocit-K), sodium bicarbonate, and sodium citrate (Bicitra, Cytra-2, Liqui-Citra, Oracit, Shohl's).
