Lisinopril and taste changes

Why ACE inhibitors like lisinopril can change your sense of taste, when the effect usually fades, and what to do if it does not.

Dry mouth

Never start, stop, or change a medication based on what you read here. Bring questions to your dentist, physician, pharmacist, or prescribing clinician.

Quick answer

Lisinopril can cause altered taste, including a metallic taste, reduced taste sensitivity, or food tasting strange. This is a known side effect of ACE inhibitors as a class. It usually appears in the first few weeks and resolves on its own, but a minority of patients have persistent changes. Lisinopril does not cause the gum overgrowth seen with calcium channel blockers like amlodipine, but it does affect a related cluster of oral side effects (cough, taste, rarely angioedema).

The mechanism

Why lisinopril affects taste

Lisinopril works by blocking the angiotensin-converting enzyme (ACE), which lowers blood pressure. ACE also helps regulate zinc metabolism in the body, and zinc is essential for normal taste perception. ACE inhibitors can subtly disrupt this balance, leading to taste changes in a small percentage of users.

The most common report is a metallic or bitter taste, sometimes accompanied by reduced ability to taste sweetness or saltiness. Foods can taste flat or different from before. Some patients also describe a persistent unusual aftertaste even when not eating.

Taste sensation is also affected by saliva flow. Lisinopril is associated with mild dry mouth in some patients, which compounds the taste change. The combination is usually mild but can be enough to make some foods unappealing, which occasionally leads to weight loss in elderly patients.

Practical steps

What to do about a taste change on lisinopril

Give it four to eight weeks. Many cases resolve as the body adjusts.
Stay well hydrated. Saliva flow affects how strongly you taste food.
Brush your tongue gently with your toothbrush at the back where bacteria accumulate.
Ask your physician about alternative ACE inhibitors or different drug classes if the taste change is severe and persistent. ARBs (like losartan) usually do not cause the same effect.
Track which foods are affected. Some patients can adapt by adjusting seasoning rather than switching medications.
Get a dental check to rule out other causes of taste change, especially if you have not been seen recently.

Signs to watch for

When to call your dentist

  • A taste change that does not improve after eight to twelve weeks.
  • A new sore or ulcer in the mouth that does not heal in two weeks.
  • Sudden swelling of the lips, tongue, or throat (this is a medical emergency, possibly angioedema, not a routine dental issue).
  • Persistent bad breath even with good hygiene.
  • Localized bad taste from one specific spot, which usually means an infected tooth or gum.
