- Most sore throats are caused by viruses and improve on their own within about one week.
- Fluids, warm salt-water gargles, honey for people older than 1 year, and properly humidified air may ease discomfort.
- Acetaminophen or ibuprofen may reduce pain and fever when they are appropriate for the person and used exactly as directed.
- Antibiotics do not treat viral sore throats. Group A strep normally requires testing before antibiotics are prescribed.
- Difficulty breathing, inability to swallow, drooling, stridor, dehydration, or rapidly worsening symptoms require prompt medical attention.
Most uncomplicated sore throats can be managed at home with fluids, rest, soothing treatments, and appropriate pain relief. However, a sore throat can occasionally be a sign of strep throat or a more serious condition, so it is important to recognize the warning signs.
Viruses are the most common cause of a sore throat. Group A strep causes an estimated 20%–30% of sore-throat cases in children and 5%–15% in adults. A cough, runny nose, hoarseness, or pink eye makes a viral cause more likely. When clear viral symptoms are absent, an examination alone cannot reliably distinguish strep from a viral infection, and testing may be needed.
This article provides general information and does not replace medical advice, diagnosis, or treatment.
What Helps a Sore Throat Quickly?
Start by drinking water or another warm or cold beverage. Warm liquids may feel soothing, while cold drinks, ice chips, or frozen fruit pops may temporarily numb the discomfort.
Adults and older children who can gargle safely may try warm salt water. Honey in warm water or caffeine-free tea may help soothe throat irritation and an accompanying cough, but it must never be given to a child younger than 12 months.
A clean cool-mist humidifier can help when the air is dry. Acetaminophen or ibuprofen may also reduce pain and fever when used according to the label and when appropriate for the person’s age and medical history.
These measures can ease symptoms, but they do not cure the underlying infection.
Check for Emergency Warning Signs
Seek emergency medical care if you or your child:
- Has difficulty breathing
- Cannot swallow fluids or saliva
- Is drooling because swallowing is too difficult
- Makes a high-pitched sound when breathing in, known as stridor
- Has severe symptoms that are worsening quickly
- Is unusually difficult to wake or appears seriously unwell
Contact a healthcare professional promptly for signs of dehydration, such as very little urination, a dry mouth, dizziness, or an inability to keep fluids down.
A baby younger than 3 months with a temperature of 100.4°F/38°C or higher also needs prompt medical advice.
Common Causes of a Sore Throat
A sore throat may be caused by a cold, flu, COVID-19, strep throat, allergies, dry air, smoke exposure, vaping, heavy voice use, or acid reflux.
The following table can help you decide on a reasonable next step, but it cannot diagnose the cause.
| Symptom pattern | What to consider | Next step |
| Sore throat with a cough, runny nose, hoarseness, or pink eye | A viral respiratory infection is more likely | Use supportive care and consider flu or COVID-19 testing when relevant |
| Sudden sore throat with fever, painful swallowing, tender neck glands, or red and swollen tonsils, especially without a cough | Group A strep is possible | Ask whether a rapid strep test or throat culture is appropriate |
| Symptoms linked to dry air, smoke, vaping, allergies, voice use, or reflux | Irritation may be contributing | Reduce the trigger and seek advice if symptoms persist |
| Difficulty breathing, inability to swallow, drooling, stridor, or rapid worsening | A potentially serious throat or airway problem | Seek emergency care |
Flu and COVID-19 can both cause a sore throat, and their symptoms may overlap. People at increased risk of severe illness should seek medical advice early. Flu antivirals work best when started within one or two days, while eligible COVID-19 treatments generally must begin within five to seven days after symptoms start.
How to Soothe a Sore Throat at Home
Drink plenty of fluids
Water helps keep the throat moist and reduces the risk of dehydration. Warm broth, warm water, or caffeine-free tea may feel soothing. Chilled water, ice chips, or frozen fruit pops may provide temporary numbing relief.
Choose the temperature that feels most comfortable, and avoid liquids that are hot enough to burn.
If swallowing is painful, take frequent small sips. Soft foods such as soup, yogurt, oatmeal, scrambled eggs, or smoothies may be easier to eat. Avoid foods and drinks that noticeably worsen the irritation, which may include very hot, dry, spicy, or acidic items.
Gargle with warm salt water
Dissolve approximately one-half teaspoon of table salt in an 8-ounce glass of warm water. Gargle for several seconds and spit the water out.
Salt-water gargling may temporarily soothe irritation, but it does not cure a viral or bacterial infection. It should be used only by adults and children who can gargle reliably without swallowing the solution.
Try honey if it is safe
Honey may soothe an irritating cough and throat discomfort. Add a small amount to warm water or caffeine-free tea, or take it by itself.
Never give honey to a child younger than 12 months because it may cause infant botulism. Remember that honey contains sugar, so use a modest amount when appropriate.
Add moisture to dry air
A cool-mist humidifier may reduce irritation caused by dry indoor air. Clean and maintain the humidifier exactly as directed by the manufacturer because germs can grow in the water tank and spread through the mist.
Avoid placing your face over a bowl or container of very hot water. Steam treatments can cause serious burns, particularly in children.
Avoid smoke and other irritants
Avoid cigarette smoke, secondhand smoke, vaping aerosols, incense, and harsh chemical fumes. Rest your voice, and avoid shouting or whispering, both of which can increase strain.
Use lozenges carefully
Throat lozenges or hard candy can stimulate saliva and provide temporary relief. Follow the label when using medicated lozenges or sprays.
Do not give small, hard items to young children or anyone who may have difficulty swallowing because of the choking risk.
Can Pain Medicine Help?
Acetaminophen or ibuprofen may reduce throat pain, body aches, and fever. They will not cure the infection, but they may make it easier to drink, eat, and rest.
Use a product that is appropriate for the person’s age and health. Follow the Drug Facts label, and check the active ingredients before combining products. Many multi-symptom cold medicines already contain acetaminophen, so taking an additional acetaminophen product can cause an accidental overdose.
Ask a pharmacist or clinician before using pain medicine if you are pregnant, take blood thinners, have stomach ulcers, kidney disease, liver disease, a medication allergy, or another significant health condition.
For a child:
- Use only a product intended for children of that age and weight.
- Follow the weight-based instructions on the label.
- Measure liquid medicine with the supplied syringe or cup, not a household spoon.
- Never give a child a product packaged for adults.
- Ask a clinician or pharmacist when the child is very young or when you are unsure about the dose.
The FDA does not recommend over-the-counter cough and cold medicines for children younger than 2 years, and manufacturers commonly label these products “Do not use in children under 4 years of age.”
Never give aspirin to a child or teenager with a viral illness unless a clinician has specifically prescribed it. Aspirin use during certain viral illnesses is associated with Reye syndrome, a rare but serious condition.
What Should You Avoid?
Do not take leftover antibiotics or medicine prescribed for another person. Antibiotics do not treat viral sore throats and can cause side effects when they are not needed.
When testing confirms group A strep, antibiotics can shorten symptoms, reduce transmission, and lower the risk of complications. Take the entire course exactly as prescribed.
Be cautious with herbal remedies, essential oils, homeopathic products, and products marketed as “natural.” Evidence for many of them is limited, and some can interact with medicines or be unsuitable during pregnancy, breastfeeding, or childhood.
Do not apply undiluted essential oils inside the mouth or throat, and do not inhale very hot steam.
When Should You Get a Strep Test?
Ask about strep testing when a sore throat begins suddenly and occurs with symptoms such as:
- Fever
- Painful swallowing
- Tender glands at the front of the neck
- Red or swollen tonsils
- White tonsil patches
- A fine, rough-feeling rash
- An absence of cough, runny nose, and hoarseness
These signs can suggest strep, but they cannot confirm it. A rapid antigen test or throat culture is used for diagnosis.
In symptomatic children aged 3 years or older, a negative rapid test may need to be followed by a throat culture. A backup culture after a negative rapid test is not routinely required for most adults.
When Should You See a Healthcare Professional?
Arrange medical advice when the sore throat:
- Is getting worse instead of better
- Has not noticeably improved after several days or lasts longer than about one week
- Keeps returning
- Occurs with dehydration, a rash, persistent fever, neck swelling, blood in the saliva, or difficulty opening the mouth
- Occurs in someone with a weakened immune system
- Does not improve within approximately 48 hours after starting antibiotics for confirmed strep
A mouth ulcer lasting more than three weeks, an unexplained lump in the mouth or neck, persistent hoarseness, or a sore throat that does not go away should also be examined. These symptoms often have noncancerous causes, but they should not be ignored.
How to Help a Child With a Sore Throat
Offer frequent small drinks and soft or cold foods. Honey may be offered only after the child’s first birthday.
Do not use salt-water gargles until the child can gargle and spit reliably. Avoid hard lozenges, ice cubes, or candy when there is a choking risk.
Use child-specific pain or fever medicine only when appropriate. Follow the weight-based label directions and measure liquid medicine with the device supplied with the product.
Seek prompt care if the child:
- Struggles to breathe
- Cannot swallow fluids
- Drools because swallowing is difficult
- Shows signs of dehydration
- Is unusually sleepy or difficult to wake
- Develops a concerning rash
- Is becoming worse quickly
How Long Does a Sore Throat Last?
Most uncomplicated viral sore throats improve within about one week. Irritation caused by dry air, smoke, allergies, or reflux may continue until the underlying trigger is controlled.
When you have symptoms of a respiratory infection, stay home and away from others until your symptoms are improving overall and you have been fever-free without fever-reducing medicine for at least 24 hours. For the following five days, consider additional precautions such as good ventilation, careful hand hygiene, distancing, testing, or wearing a well-fitting mask around others.
For confirmed strep throat, stay home until you no longer have a fever and have taken an appropriate antibiotic for at least 12–24 hours, following your clinician’s advice.
Frequently Asked Questions
Can a sore throat be contagious without a fever?
Yes. Viral and bacterial infections can spread even when no fever is present. Whether the sore throat is contagious depends on its cause, not on whether a fever occurs.
A sore throat caused by allergies, dry air, reflux, smoke, or voice strain is not contagious.
Why is my sore throat worse in the morning?
Dry air, mouth breathing, nasal congestion, postnasal drip, or acid reflux can irritate the throat overnight.
Drinking water, improving room humidity, and addressing nasal congestion may help. Speak with a healthcare professional if morning symptoms happen frequently or are accompanied by persistent hoarseness, difficulty swallowing, or reflux symptoms.
Can allergies cause a sore throat?
Yes. Allergies can cause nasal drainage that irritates the back of the throat. Allergy-related symptoms may recur during certain seasons or after exposure to dust, pollen, mold, or animals.
Fever and significant body aches are less typical of allergies and may point toward an infection.
Can acid reflux cause a sore throat?
Yes. Stomach contents can irritate the throat, sometimes without causing obvious heartburn. Reflux may be more likely when the sore throat is recurrent, worse after meals or when lying down, or accompanied by a sour taste, throat clearing, or hoarseness.
Persistent symptoms should be medically assessed rather than treated repeatedly with home remedies.
What happens if a rapid strep test is negative?
For most adults, a follow-up throat culture is not routinely necessary. In symptomatic children aged 3 years or older, a clinician may send a throat culture to confirm a negative rapid result.
Why does my sore throat keep coming back?
Recurring sore throats may be caused by repeated infections, allergies, dry indoor air, smoke exposure, reflux, mouth breathing, or ongoing voice strain.
A healthcare professional should evaluate recurrent symptoms, especially when they are severe, occur with neck swelling, or interfere with swallowing or breathing.
