Lithium, a mood stabilizer used for bipolar disorder, poses a high risk when used in patients with kidney disease due to impaired renal excretion, leading to potential toxicity.
Contraindicated in severe renal impairment (eGFR <30 mL/min); use only if benefits outweigh risks in milder cases.
Monitor serum lithium levels at least every 3-6 months, more frequently with dose changes or worsening renal function.
Watch for signs of toxicity (e.g., fine tremor, polyuria) and adjust or stop therapy promptly.
Ensure adequate hydration to support renal function.
Lithium is primarily excreted unchanged by the kidneys via glomerular filtration and partial tubular reabsorption. In kidney disease, reduced glomerular filtration rate (GFR) decreases lithium clearance, resulting in accumulation and elevated serum concentrations.
Risk of lithium toxicity, which can cause nausea, vomiting, diarrhea, tremor, confusion, ataxia, seizures, coma, and further renal deterioration; severe cases may lead to permanent neurological damage or death.
Lithium is generally contraindicated in moderate to severe chronic kidney disease (CKD stages 3-5). If use is unavoidable, initiate at low doses with frequent monitoring of serum lithium levels (target 0.6-1.2 mEq/L), renal function (eGFR, creatinine), and electrolytes. Consider discontinuation if GFR <30 mL/min or toxicity develops; alternative therapies like valproate or lamotrigine are preferred.

Hot chocolate contains small amounts of tyramine and phenylethylamine, which can interact with MAOIs, potentially leading to a hypertensive crisis if consumed in large quantities, though the risk is generally low with moderate intake.
Kale, a vitamin K-rich leafy green, can interact with warfarin by potentially reducing its anticoagulant effects if intake is inconsistent or excessive.
Large amounts of lime juice may mildly interact with certain statins, similar to but less potent than grapefruit juice, by inhibiting drug metabolism and potentially increasing statin levels in the blood.
