What it does
Trandolapril is used to treat high blood pressure.
Common side effects
Cough, Dizziness
Key warnings
If you become pregnant, stop taking trandolapril right away.
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.
Pregnancy & Breastfeeding
Do not take trandolapril if you are pregnant. It can cause serious harm to your unborn baby. Talk to your doctor about other blood pressure medicines if you are breastfeeding.
Missed Dose
If you miss a dose, take it as soon as you remember. If it is close to your next dose, skip the missed dose and continue with your regular schedule.
Storage
Store trandolapril tablets at room temperature, between 68°F and 77°F.

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.

What the FDA Data Shows for trandolapril
The FDA label for trandolapril (sold under brand names such as Mavik) classifies it as a prescription-only medication in the ACE Inhibitor class. Trandolapril is used to treat high blood pressure. Official labeling lists 2 commonly reported side effects, including Cough, Dizziness.
Post-market surveillance from the FDA Adverse Event Reporting System (FAERS) captures real-world experience. For this drug, FAERS contains 1,014 voluntary reports. The database also lists 8 documented drug interactions derived from FDA labeling, with the top-flagged interaction rated major severity. NADAC pricing from CMS shows a generic unit cost of $0.17.
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.
