Serious Warnings

If you become pregnant, stop taking trandolapril right away. This medicine can harm or cause death to your unborn baby.

Known Drug Interactions

Drug Interactions Dual Blockade of the Renin-Angiotensin System (RAS) Dual blockade of the RAS with angiotensin receptor blockers, ACE inhibitors, or aliskiren is associated with increased risks of hypotension, hyperkalemia, and changes in renal function (including acute renal failure) compared to monotherapy. Do not co-administer aliskiren with trandolapril in patients with diabetes. Avoid use of aliskiren with trandolapril in patients with renal impairment (GFR <60 mL/min).

Mechanism: Both drugs target the same system for controlling blood pressure, which can overwork the kidneys. This increases the risk of very low blood pressure and high potassium levels.

Use of potassium-sparing diuretics (spironolactone, triamterene, or amiloride), potassium supplements, or potassium-containing salt substitutes concomitantly with ACE inhibitors can increase the risk of hyperkalemia.

Mechanism: Both of these medicines cause the body to keep potassium instead of getting rid of it, which can lead to dangerously high levels in the blood.

moderate lithium

Lithium Increased serum lithium levels and symptoms of lithium toxicity have been reported in patients receiving concomitant lithium and ACE inhibitor therapy. These drugs should be coadministered with caution, and frequent monitoring of serum lithium levels is recommended. If a diuretic is also used, the risk of lithium toxicity may be increased.

Mechanism: Trandolapril can make it harder for your body to clear lithium, which may cause the lithium to build up to toxic levels.

moderate amiloride

Use of potassium-sparing diuretics (spironolactone, triamterene, or amiloride), potassium supplements, or potassium-containing salt substitutes concomitantly with ACE inhibitors can increase the risk of hyperkalemia.

Mechanism: These drugs both prevent the body from removing potassium, which can cause potassium levels in your blood to become too high.

Other No clinically significant pharmacokinetic interaction has been found between trandolaprilat and food, cimetidine, digoxin, or furosemide.

Mechanism: Studies show that these two medications do not interfere with each other in the body. They can be processed by the body at the same time without issues.

Report counts do not establish causation, a FAERS entry documents a temporal association, not proof that the drug produced the outcome. Widely prescribed medications naturally accumulate more reports than niche therapies, so raw totals must be interpreted alongside total exposure. Shortage status, recall history, and patent information are separate source-record fields.
