How do I get rid of the cough from lisinopril?

Lisinopril is a widely prescribed blood-pressure medication in the ACE-inhibitor family. While it’s generally well tolerated, up to 10–20 percent of people experience a dry, persistent cough as one of the more common lisinopril side effects. If you’re one of them, here’s how to ease or eliminate that cough while keeping your blood pressure in check.

Why does lisinopril cause a cough?

ACE inhibitors like lisinopril block the enzyme that breaks down bradykinin, a naturally occurring peptide in your lungs. Elevated bradykinin levels can irritate airway nerves, triggering a dry cough that:

• Often starts weeks to months after you begin lisinopril
• Is usually non-productive (no mucus)
• May worsen at night or when you lie down

Understanding that this cough is drug-related can help you find strategies to manage it, rather than worrying about a more serious lung condition.

Self-care steps to ease your cough

Before making any changes to your prescription, try these simple, low-risk remedies:

• Stay well-hydrated
  • Warm fluids (herbal tea, broth) can soothe irritated throat tissues
  • Room-temperature water sipped throughout the day helps thin airway secretions
• Use a humidifier
  • Adding moisture to dry air can calm cough reflexes
  • Clean your humidifier daily to prevent mold
• Honey and throat lozenges
  • One teaspoon of honey before bed coats and soothes the throat
  • Menthol or eucalyptus lozenges can provide temporary relief
• Elevate your head at night
  • A few extra pillows can reduce post-nasal drip and reflux, both of which worsen cough
• Avoid lung irritants
  • Steer clear of cigarette smoke, strong perfumes or cleaning sprays
  • If you live in a dry climate, consider an indoor air purifier

These measures won’t always eliminate an ACE-inhibitor cough, but many patients notice a meaningful reduction in discomfort.

Over-the-counter and dietary aids

If your cough persists despite self-care:

• Cough suppressants
  • Dextromethorphan or other OTC syrups can calm a bothersome cough reflex
• Expectorants
  • Guaifenesin may help if you develop any loose mucus
• Anti-acid remedies
  • If mild reflux is contributing, consider an acid reducer (H2 blocker or antacid) after checking with your pharmacist

Always read labels for interactions and talk to a pharmacist if you’re on multiple medications.

Recognizing when to seek medical advice

Most ACE-inhibitor coughs are harmless but do check with a healthcare professional if you notice:

• Cough lasting more than 2–4 weeks despite self-care
• Blood in your sputum or frequent chest discomfort
• Shortness of breath that interferes with daily activities
• Swelling of the face, lips or tongue (signs of a rare but serious reaction)

Prescription adjustments your doctor may suggest

If lifestyle measures and OTC aids don’t help, your provider might recommend:

• Switching to an ARB (angiotensin II receptor blocker) such as losartan or valsartan
  • ARBs work on a similar pathway but rarely cause cough
• Trying a different ACE inhibitor at a lower dose
• Adjusting your lisinopril dose or dosing schedule
• Adding a mild diuretic or calcium-channel blocker if you need extra blood-pressure control

Never stop or change prescription medications on your own. Your doctor will balance cough relief with optimal blood-pressure management.

Monitoring and follow-up

Once you and your provider settle on a new regimen:

• Keep a daily log of your cough frequency and severity
• Track blood pressure at home with a reliable monitor
• Note any new symptoms, such as dizziness, swelling or fatigue
• Schedule a follow-up visit or telehealth check-in within 4–6 weeks

This will help ensure that your new therapy keeps your blood pressure in range without unwanted side effects.

When coughs mask more serious problems

A persistent cough can occasionally signal a lung infection, asthma, reflux disease or, rarely, heart failure. Be especially vigilant if you develop:

• Fever, chills or night sweats
• Wheezing or audible chest rattling
• Significant weight loss or decreased appetite
• Swelling in your legs or rapid heartbeat

Any of these warrant prompt evaluation. If you experience sudden chest pain, severe difficulty breathing or loss of consciousness, call emergency services immediately.

Take-home points

Lisinopril’s cough is a well-known lisinopril side effect stemming from increased bradykinin in the lungs. In many cases, simple self-care measures—hydration, humidification, honey, OTC cough suppressants—can bring relief. If your cough persists or worsens, talk to your doctor about switching to an ARB or adjusting your dose. For a free, online symptom check, using the doctor approved Ubie Symptom Checker can help you decide when to seek medical care. Above all, never hesitate to speak to a healthcare professional about any symptom that could be dangerous or life-threatening.
