You can help stop a runny nose by using a saline nasal spray, drinking enough fluids, and avoiding irritants such as smoke and strong perfumes. If allergies are responsible, antihistamines or other allergy medicines may help. A runny nose caused by a common cold usually improves as the infection clears. The most effective approach depends on the cause, how long symptoms last, and whether other symptoms are present.
What is the fastest way to stop a runny nose?
For quick relief, start with a few simple measures. A runny nose occurs when the lining inside your nose produces extra fluid, often in response to an infection, an allergy, or an irritant. You may not be able to stop the discharge immediately, but you can reduce discomfort and help your nose feel clearer.
- Use a saline nasal spray: Saltwater sprays help moisturize the nasal passages and loosen mucus so it can drain more easily.
- Drink enough fluids: Water, warm tea, and clear soups help you stay hydrated while you recover from a cold.
- Try a clean humidifier: Adding moisture to dry indoor air may ease nasal irritation. Clean the device according to its instructions.
- Blow your nose gently: Use a soft tissue and avoid forceful blowing, which can irritate the skin around your nostrils.
- Avoid known triggers: Smoke, dust, strong fragrances, and other irritants may worsen nasal discharge in some people.
According to the US Centers for Disease Control and Prevention (CDC), saline nasal sprays, rest, fluids, and a clean humidifier can help relieve common cold symptoms. These measures ease discomfort but do not cure the infection itself.
Which home remedies help a runny nose?
Home remedies can make a runny nose easier to manage, particularly when it occurs with a common cold or irritation from dry air. Choose methods that soothe the nose without exposing it to additional irritants or unsafe substances.
Use saline nasal spray or a nasal rinse
Saline is a mixture of salt and water. It can help moisten the inside of your nose, loosen mucus, and wash away some irritants. Ready-made saline sprays are convenient for regular use according to the product instructions.
A nasal rinse uses a larger volume of saline to flush mucus and debris from the nasal passages. If you use a rinse bottle, neti pot, or another irrigation device, use distilled, sterile, or previously boiled and cooled water. Never use untreated tap water for nasal irrigation. Clean and dry the device according to its instructions.
Mayo Clinic's guidance on cold remedies identifies saline nasal drops and sprays as useful options for easing nasal symptoms.
Drink warm fluids and stay hydrated
Water, warm tea, broth, and other suitable drinks help maintain hydration. Warm fluids may also provide temporary comfort when a runny nose occurs alongside a sore throat or other cold symptoms. You do not need to force yourself to drink excessive amounts; drink regularly and according to your usual needs.
Keep indoor air comfortable
Dry air can irritate the nose, so a clean cool-mist humidifier may help when indoor air is dry. Follow the manufacturer's instructions for cleaning and changing the water to prevent the growth of microorganisms. Avoid inhaling steam directly from a bowl of boiling water because it can cause serious burns. A comfortably warm shower may provide temporary relief without that risk.
Protect the skin around your nose
Frequent wiping can make the skin around your nostrils red, sore, or cracked. Use soft tissues, dab rather than rub, and apply a small amount of a gentle, fragrance-free moisturizer to the external skin if needed. Avoid putting ordinary skin creams or petroleum-based products deep inside your nostrils unless a healthcare professional recommends them.
Which medicines can stop a runny nose?
Medicines may help when home remedies are not enough, but the best option depends on the cause. A medicine that works well for allergies may have limited benefit for a viral infection. Read product labels carefully and ask a pharmacist or healthcare professional for advice if you have other medical conditions, take regular medicines, are pregnant, or are choosing treatment for a child.
Antihistamines for allergy-related symptoms
Antihistamines block the effects of histamine, a substance involved in allergic reactions. They may reduce a runny nose, sneezing, and itching when these symptoms are related to allergies. Some antihistamines can cause drowsiness, while others are less likely to do so. Check the label before driving or operating machinery, and ask a pharmacist which option is appropriate for you.
MedlinePlus guidance on allergic rhinitis describes antihistamines, saline nasal washes, and other treatments that may help manage allergy symptoms.
Nasal corticosteroid sprays for persistent allergies
Nasal corticosteroid sprays reduce inflammation inside the nose. They are often used for allergic rhinitis, particularly when symptoms are frequent or persistent. They may help with a runny nose, sneezing, and nasal congestion, but they generally work best when used regularly as directed rather than as a one-time treatment. Follow the product instructions and ask a healthcare professional or pharmacist about the right choice for your symptoms.
These sprays are different from decongestant sprays. They do not usually provide the same immediate sensation of an open nose, and their full benefit may take time to develop.
Decongestants and nasal sprays
Decongestants narrow swollen blood vessels in the nasal lining and are mainly used to relieve a blocked nose. They may help with some nasal symptoms, but they are not always the best choice for a nose that is simply dripping. Oral decongestants can cause side effects, including increased blood pressure, a racing heartbeat, or difficulty sleeping in some people.
Decongestant nasal sprays can cause rebound congestion if used for too long. Follow the label's duration limit, which is often no more than three consecutive days for common products, and ask a pharmacist if you are unsure. People with high blood pressure, heart disease, glaucoma, thyroid conditions, or other relevant health problems should seek advice before using decongestants.
What about combination cold medicines?
Combination cold medicines may contain several ingredients, such as an antihistamine, decongestant, or pain reliever. Taking more than one product with the same active ingredient can lead to an accidental overdose. Check the ingredient list rather than relying only on the product name, and follow the recommended dose.
MedlinePlus information on cold and cough medicines explains the different types of ingredients and the importance of using them according to their labels. Antibiotics do not treat the viruses responsible for common colds and should not be used for an uncomplicated viral infection unless prescribed for a separate, appropriate reason.
How can you stop a runny nose caused by allergies?
If your nose starts running around pets, during pollen season, or after exposure to dust, an allergic reaction may be contributing to the symptoms. Other experiences that can occur with allergies include repeated sneezing, an itchy nose, and watery or itchy eyes. These features can offer clues, but they do not establish a diagnosis on their own.
To reduce allergy-related symptoms, consider the following steps:
- Reduce exposure to triggers you already know affect you, such as pollen, pet dander, or household dust.
- Keep windows closed when outdoor pollen levels are high, if pollen is a known trigger.
- Change clothes and shower after spending time outdoors when pollen exposure is a concern.
- Use a saline spray or rinse to help remove mucus and some irritants.
- Ask a pharmacist or healthcare professional whether an antihistamine or nasal corticosteroid spray is appropriate.
According to Mayo Clinic's comparison of colds and allergies, both conditions can cause a runny nose and sneezing. Itchy eyes and recurring symptoms linked to particular seasons or exposures may occur with allergies, while a cold may also cause a sore throat, cough, or fever.
How do you stop a runny nose caused by a cold?
A runny nose is a common symptom of a viral upper respiratory infection. There is no medicine that reliably stops an ordinary cold immediately, so treatment focuses on easing symptoms while the body recovers. Rest, fluids, saline nasal spray, and a clean humidifier may help you feel more comfortable.
Most common colds improve within about 7 to 10 days, although some symptoms can last longer. The mucus may change from clear to thicker or yellow-green during the illness. That color change alone does not mean that the infection is bacterial or that antibiotics are needed.
Stay home when you feel too unwell to manage your usual activities, and practice good hand hygiene to reduce the spread of respiratory infections. If symptoms worsen, fail to improve as expected, or are accompanied by concerning features, seek medical advice rather than continuing to rely on home remedies alone.
How can you manage a runny nose in babies and children?
Children need age-appropriate treatment because some medicines used by adults can be harmful to young children. For babies and young children, saline nasal drops followed by gentle suction with a bulb syringe may help clear mucus, especially when nasal discharge interferes with feeding or sleep.
Offer fluids appropriate for the child's age and keep the air comfortable. Do not give over-the-counter cough and cold medicines to young children without checking the relevant age guidance and speaking with a healthcare professional. The CDC advises against these medicines for children younger than six years because of the risk of serious side effects.
Contact a healthcare professional if a child has difficulty breathing, cannot feed or drink adequately, shows signs of dehydration, or becomes unusually sleepy. A baby younger than three months with a temperature of 38°C (100.4°F) or higher needs prompt medical assessment.
When should you see a doctor for a runny nose?
A runny nose often improves with simple care, but persistent, worsening, or unusual symptoms may need medical evaluation. A healthcare professional can consider the duration and pattern of symptoms, other symptoms, medical history, and examination findings to determine whether further assessment or treatment is needed.
Arrange a medical appointment if your symptoms do not improve after about 10 days, become worse after initially improving, keep returning, interfere with sleep or daily activities, or do not respond to appropriate self-care. Seek advice sooner if you have a persistent fever, significant facial pain, or other symptoms that concern you.
Seek urgent medical attention if a runny nose occurs with difficulty breathing, severe headache with a stiff neck, confusion, or other serious symptoms. A persistent discharge from only one nostril, particularly if it is bloody or foul-smelling, also warrants assessment. Clear fluid leaking continuously from one nostril after a head injury requires urgent evaluation.
What should you avoid when trying to stop a runny nose?
Some approaches can cause more harm than benefit. Avoid the following:
- Overusing decongestant nasal sprays: Prolonged use can cause rebound congestion.
- Taking unnecessary antibiotics: Antibiotics do not treat viral colds and can cause side effects.
- Using untreated tap water for nasal rinses: Use distilled, sterile, or previously boiled and cooled water instead.
- Inhaling steam from boiling water: This can cause burns. Choose safer ways to add moisture to the air.
- Combining medicines without checking ingredients: Multiple products may contain the same active ingredient.
- Giving adult cold medicines to children: Children's treatment must follow age-specific guidance and appropriate dosing instructions.
The goal is to relieve the runny nose safely while addressing the reason it is happening. If the cause is unclear or symptoms continue, a healthcare professional can help determine which treatment is most suitable.
