minor Known Drug Interaction
Lithium: Reversible increases in serum lithium concentrations and toxicity have been reported during concomitant administration of lithium with angiotensin II receptor antagonists including telmisartan. Therefore, monitor serum lithium levels during concomitant use.
Lithobid, Eskalith
Micardis
Lithium is a mood stabilizer medicine. It helps to balance mood swings.
Telmisartan (Micardis) is a medicine that lowers blood pressure. It belongs to a class of drugs called angiotensin II receptor blockers (ARBs).
Lithium is used to treat bipolar disorder. Bipolar disorder causes unusual shifts in mood, energy, activity levels, and concentration. Lithium helps to control the extreme highs (mania) and lows (depression) of this condition.
Telmisartan is used to treat high blood pressure. Lowering blood pressure reduces the risk of strokes and heart attacks. It can also lower cardiovascular risk if you cannot take ACE inhibitors. Controlling high blood pressure is important for overall heart health.
Lithium affects the flow of sodium in nerve and muscle cells in the body. This helps to stabilize your mood. It may also affect other chemical messenger systems in the brain.
Telmisartan blocks a substance in your body that tightens blood vessels. This helps blood vessels relax and widens them. As a result, blood pressure is lowered.

How to Read This lithium vs telmisartan Comparison
lithium is classified in the Mood Stabilizer drug class, while telmisartan sits within the Angiotensin II Receptor Blocker (ARB) class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, lithium has 7,664 submissions while telmisartan has 9,354. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known minor interaction flagged in FDA labeling, attributed to telmisartan can make it harder for your kidneys to get rid of lithium, leading to a buildup of lithium in your blood.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot represent individual circumstances. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information. This registry does not provide medical, treatment, substitution, or medication-change directions for lithium or telmisartan.
