How to Get Rid of Congestion Fast

DetoxWater Editorial Team•Published November 5, 2026

For fast congestion relief, an oxymetazoline nasal spray can work quickly; saline spray or a rinse and a clean humidifier may also help. These remedies address a blocked or stuffy nose, not chest congestion.

A cold, allergies and other irritants can all cause nasal congestion, so the most helpful approach depends partly on what is causing it. For additional hydration ideas, see the best drinks for congestion.

5 home remedies for fast congestion relief

1. Use an oxymetazoline nasal spray

Oxymetazoline is a medicated nasal decongestant. It narrows blood vessels in the nasal lining, reducing swelling so air can pass through more easily. It relieves congestion temporarily; it does not cure a cold or address the underlying cause of allergies.

For an adult, follow the package directions for the amount and timing. Blow your nose gently first, then hold the bottle upright and point the nozzle slightly outward, away from the middle of your nose. Breathe in gently as you spray, and do not share the bottle.

Do not use the spray for more than 3 days, or longer than the package directs, unless a clinician specifically tells you to. Overuse can cause rebound congestion, in which the nose becomes blocked again. If you still need relief after the recommended period, ask a pharmacist or clinician what to do next.

Check with a clinician or pharmacist before use if you are pregnant or breastfeeding, or have high blood pressure, heart disease, thyroid disease, diabetes, glaucoma or difficulty urinating. Also check if you take other decongestants or antidepressants, especially a medicine called an MAO inhibitor. Ask a clinician about an age-appropriate product before using a decongestant spray for a child.

Evidence: A 2026 review of topical nasal decongestants found that oxymetazoline can rapidly improve congestion. The exact timing of rebound congestion remains uncertain, so follow the product label rather than extending use on your own.

2. Try a saline spray or nasal rinse

Saline moistens the nasal passages and can help clear mucus and irritants. Unlike oxymetazoline, it does not work by narrowing blood vessels, so it may not reduce swelling as quickly. It can be useful when your nose feels dry as well as blocked.

Use a ready-to-use saline spray according to its label. For a rinse, follow the device instructions: generally, you lean over a sink, tilt your head and let the solution flow through the nasal passages. Breathe through your mouth and blow your nose gently afterward. Do not force a rinse if your nostrils are completely blocked or it causes pain or ear pressure.

For nasal rinsing, use only distilled, sterile, or previously boiled and cooled water to prepare the solution and to rinse the device after cleaning. Do not use unboiled tap water. Wash and dry the device according to its instructions; a ready-to-use saline spray does not require you to add water.

Evidence: Saline may provide temporary relief by clearing and moistening the nose, but the speed and size of its effect are uncertain. The decongestant review cited above studied medicated sprays, not saline.

3. Run a clean humidifier

Dry air can make the nasal lining feel irritated and mucus feel dry. A cool-mist humidifier adds moisture to the air, which may make breathing feel more comfortable. It is less likely to be a quick answer when swelling, rather than dryness, is the main problem.

Place the humidifier where its mist is not directed at a person or bedding, and follow the manufacturer’s instructions. Empty and dry the tank daily and clean the device as directed; a dirty humidifier can put unwanted particles or microbes into the air. Avoid making the room damp enough for condensation or mold to develop.

Do not lean over a bowl of hot water to inhale steam. It can cause scalds and is not a proven fast fix for congestion.

Evidence: Evidence that home humidifiers rapidly relieve nasal congestion is limited. Any benefit may be more noticeable for dryness than for a severely blocked nose.

4. Drink enough fluids

Staying hydrated can help keep mucus from becoming dry and sticky. Drinking water is a supportive measure, not a decongestant: it will not reliably shrink swollen nasal tissue or clear a blocked nose immediately.

Drink water regularly, especially if you have been eating or drinking less while unwell. A warm drink may feel soothing, but choose a temperature that will not burn your mouth. You do not need to force large amounts of fluid; if a clinician has advised you to limit fluids, follow that advice.

Evidence: Hydration supports normal body function, but there is no strong evidence that drinking more water rapidly relieves nasal congestion. Use it for comfort rather than expecting the same effect as a medicated spray.

5. Raise your head when resting

Congestion can feel more noticeable when you lie flat. Keeping your head and upper body raised may make it easier to rest comfortably, although it does not treat the cause of the congestion.

If you are an adult, try an extra pillow or a comfortable position that supports your upper body without sharply bending your neck. Adjust your position if it causes discomfort, and stop if it does not help. This is an option to try alongside other measures, not a substitute for medical care when symptoms are concerning.

Do not use pillows, wedges or inclined sleep surfaces for a baby with congestion. Babies should sleep on their backs on a firm, flat surface.

Evidence: Elevating your head may improve comfort for some people, but evidence that it quickly clears nasal congestion is limited.

When should you see a doctor for congestion?

Seek emergency care for severe trouble breathing, blue or gray lips, or confusion. Also seek urgent medical attention for swelling around an eye or a change in vision, particularly with facial pain or fever.

Contact a clinician if congestion lasts more than 10 days without improvement, gets better and then worsens, or comes with persistent fever or significant facial pain. Frequent nosebleeds, recurring symptoms or symptoms mainly on one side also deserve medical advice. A clinician can assess the cause rather than assuming every blocked nose is a cold.

For a baby younger than 3 months with a fever, seek medical care promptly. Get prompt advice for a child who is having difficulty feeding or breathing. People with weakened immune systems or serious underlying conditions should also ask a clinician when new or worsening symptoms need assessment.

Frequently asked questions

Can I use saline and a medicated nasal spray together?

Usually, saline can be used first to clear mucus, followed by the medicated spray. Follow both products’ directions and do not extend the recommended course of the decongestant.

Can blowing my nose make congestion worse?

Blowing gently can help remove mucus, but forceful or frequent blowing may irritate your nose. If your nose feels sore or bleeds, ease up and ask a clinician for advice if it continues.

How can I tell whether congestion is from allergies or a cold?

Itching and repeated sneezing may occur with allergies, while a cold can include a sore throat or fever. Symptoms overlap, so a clinician can help assess congestion that persists or keeps returning.
