Key warnings
If you become pregnant, stop taking trandolapril right away.
The sections below are summarized in plain English from trandolapril's FDA-approved prescribing information. They describe what the official label says, and are not personal medical advice.
How It Works
Trandolapril belongs to a class of drugs called ACE inhibitors. It works by blocking a substance in your body that tightens blood vessels. This helps your blood vessels relax and lowers your blood pressure.
How to Take It
If you are taking trandolapril for high blood pressure and are not on a water pill, the usual starting dose is 1 mg once a day if you are not Black, or 2 mg once a day if you are Black. Your doctor may change your dose every week based on your blood pressure. If you are taking it for heart failure after a heart attack, the usual starting dose is 1 mg once a day, and your doctor will increase it to 4 mg once a day as you tolerate it. If you have kidney problems or liver problems, the usual starting dose is 0.5 mg daily.

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.
What to do: Do not use these together if you have diabetes or kidney disease. Your doctor should check your blood pressure and kidney health often if you take both.
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.
What to do: Your doctor should check your blood potassium levels regularly if you take these two medications together.
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.
What to do: Your doctor should monitor your lithium blood levels frequently to prevent toxicity while you are taking both drugs.
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.
What to do: Your healthcare provider should monitor your blood potassium levels closely while you are using this combination.
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.
What to do: You can take these medicines together as directed by your healthcare provider. No special monitoring is required beyond your normal checkups.

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 further shape supply and switching decisions.
