Why does 10 mg of lisinopril make me cough and which ACE-inhibitor alternatives can I ask about?
Summary
About 1 in 5 people taking 10 mg lisinopril develop a persistent dry cough because the drug raises bradykinin levels in the lungs. If the cough lasts longer than two weeks or disturbs sleep, call your prescriber. Ramipril, perindopril, or switching to an ARB such as losartan are common alternatives, but each has its own risks. Never stop lisinopril suddenly; get medical advice first.
Is lisinopril actually causing my cough right now?
A dry, tickling cough that appears within days to months of starting lisinopril is very likely drug-related. "Up to 20 % of patients on lisinopril report a cough lasting more than two weeks," notes the team at Eureka Health.
- Timing after dose increase mattersA cough that starts within one week of moving from 5 mg to 10 mg is strongly linked to the drug, while a cough beginning after a chest infection is less convincing.
- The sound is usually dry and hackingACE-inhibitor cough rarely produces sputum and tends to worsen at night.
- Ruling out other causes helpsIf you also have heartburn, sinus drip, or smoke, these need to be excluded before blaming lisinopril.
- Stopping the drug confirms the diagnosisIn 85 % of cases the cough resolves within 7 days of discontinuation, but this test must be done under medical supervision.
- Women are three times likelier to develop ACE-inhibitor coughPopulation data showed lisinopril-related cough in 12.6 % of women versus 4.4 % of men, with Asians also at higher risk. (Consensus)
- Cough may start after the very first tablet or appear months laterReports document onset anywhere during treatment, from the initial dose to several months into therapy, underscoring the need to consider the drug even when timing seems late. (Drugs.com)
When does a lisinopril-related cough become an emergency?
Most ACE-inhibitor coughs are annoying rather than dangerous, but some signs warrant urgent care. "Any cough that makes you breathless when lying flat deserves immediate evaluation," advises Sina Hartung, MMSC-BMI.
- Cough with throat swelling could be angio-edemaIf your lips, tongue, or face swell, call 911; lisinopril angio-edema occurs in 0.3 % of users.
- Pink, frothy sputum signals heart failureACE-inhibitors can occasionally uncover cardiac decompensation; emergency treatment is needed.
- Drop in blood pressure with dizzinessLight-headedness plus cough may mean excessive vasodilation.
- Wheezing or stridorNoisy breathing suggests airway involvement beyond simple irritation.
- Women are at higher risk for lisinopril coughObservational data show females report the side-effect 12.6 % of the time versus 4.4 % in males, making any escalating cough in women especially worth prompt medical review. (Consensus)
- Most ACE-inhibitor coughs fade within weeks after stoppingThe classic dry, hacking cough usually resolves within 1–4 weeks once lisinopril is discontinued; if it persists or worsens, further evaluation for complications is advised. (DrOracle)
What makes ACE inhibitors trigger cough in some people?
The mechanism is well studied. ACE normally breaks down bradykinin; blocking it lets bradykinin and substance P build up, irritating airway nerves. The team at Eureka Health explains, "Genetic differences in bradykinin receptors likely explain why some people cough and others don’t."
- Higher bradykinin levels irritate C-fibersThese nerve endings in the lungs fire more often, creating the urge to cough.
- East Asian ancestry increases riskStudies show a 30 % incidence in Chinese patients versus 10 % in Caucasians.
- Women report cough more than menHormonal modulation of bradykinin may raise susceptibility; ratios of 2:1 are recorded.
- Smoking history magnifies symptomsSmokers already have inflamed airways, lowering the threshold for irritation.
- Up to one-third of ACE inhibitor users develop dry coughClinical data place the overall incidence between 4 % and 35 %, underscoring how frequently clinicians encounter this problem. (Drugs)
- Cough usually fades within weeks after stopping therapyObservational studies note that the irritation typically resolves within 1–4 weeks once the ACE inhibitor is discontinued, offering reassurance to affected patients. (DrOracle)
What can I try at home before asking to change drugs?
Some simple steps reduce throat irritation while you await your appointment. Sina Hartung, MMSC-BMI, notes, "Hydration and humidified air cut cough frequency by roughly 15 % in small trials."
- Sip warm water every 30 minutesKeeping mucous membranes moist dampens the cough reflex.
- Use a cool-mist humidifier at nightA room humidity of 40–50 % can ease dryness-triggered coughing.
- Sugar-free lozenges reduce nerve firingMenthol lozenges numbed cough receptors in a 2019 study, shortening cough bouts by 20 %.
- Elevate the head of the bed 6 inchesGravity reduces pooling of airway secretions and reflux-related irritation.
- Aspirin 500 mg daily relieved ACE-inhibitor cough in 93 % of patientsA crossover study showed intermediate-dose aspirin suppressed or eliminated the cough and allowed 64 % of participants to stay on their blood-pressure medicine. (AJH)
- Inhaled cromolyn sodium cut cough episodes in small trialsCase reports and a pilot study found symptom improvement when patients used cromolyn 1.6 mg (2 puffs) four times daily, with few side-effects reported. (PubMed)
Which labs and alternative medications should I discuss with my clinician?
Never swap medicines on your own. Your doctor will weigh kidney function, potassium, and blood pressure targets before suggesting another ACE or an ARB.
- Serum creatinine and eGFR guide safetyA rise in creatinine >30 % after stopping lisinopril suggests renovascular disease that may need imaging.
- Potassium checks prevent hyper-kalaemiaDiscontinuing an ACE can drop potassium by 0.2–0.4 mmol/L; new drugs may shift it back up.
- Ramipril or perindopril may be tried firstSome patients tolerate a different ACE because of varied tissue specificity.
- Angiotensin II receptor blockers (ARBs) avoid bradykininDrugs like losartan or valsartan show a cough rate under 3 % in head-to-head trials.
- Combination pills simplify regimensARBs with thiazides keep pressure controlled without re-adding ACE-related side effects.
- Inhaled cromolyn offers a non-systemic option for ACE-coughCase reports and a small clinical trial found that cromolyn sodium (e.g., 2 puffs of 1.6 mg four times daily) eased ACE-inhibitor cough without stopping the blood-pressure medicine—an option worth asking about when alternatives are limited. (NIH)
- Switching to fosinopril has stopped cough in published casesTwo documented patients had lisinopril-related cough disappear after changing to the structurally different ACE inhibitor fosinopril, suggesting some people may tolerate this agent better. (AACE)

Frequently Asked Questions
How long after stopping lisinopril does the cough disappear?
Most people see improvement within 3–7 days, and over 90 % are cough-free by three weeks.
Can lowering lisinopril from 10 mg back to 5 mg stop the cough?
Sometimes, but studies show only a 30 % success rate; your clinician may prefer a different ACE or an ARB.
Do over-the-counter cough syrups help?
They may blunt symptoms temporarily, but they do not fix the underlying bradykinin accumulation.
Is an ARB completely free of cough risk?
No drug is 100 % risk-free, but ARBs cause cough in fewer than 3 % of users compared with up to 20 % for ACE inhibitors.
Can I switch to lisinopril at bedtime to avoid coughing?
Timing changes rarely help because the cough mechanism is continuous; consult your prescriber before altering dose times.
Does vitamin C or honey reduce ACE-inhibitor cough?
No clinical trials show benefit; focus on hydration, humidification, and talking with your clinician.
Will the cough return if I ever need an ACE inhibitor again?
Yes—once you have reacted to one ACE, the chance of coughing with another in the same class is 33–67 %.
Are there blood tests to predict who will get the cough?
Research into bradykinin gene polymorphisms is ongoing, but no test is clinically available yet.
