October 8, 2025 •

4 min read

Approximately 81 million people in the U.S. experience allergy symptoms annually, which often includes nasal congestion. If you're wondering what drug relieves a stuffy nose, the answer depends on the cause, with options ranging from decongestants and antihistamines to nasal steroid sprays.

Quick Summary

An overview of medications for nasal congestion, including oral and topical decongestants, antihistamines, and nasal steroid sprays. The guide also covers saline options, home remedies, and important safety considerations for choosing the right treatment.

Key Points

Identify the cause: The best medication for a stuffy nose depends on whether it's caused by a cold, allergies, or chronic inflammation.
Oral decongestants shrink blood vessels systemically and are effective for cold-related congestion, with pseudoephedrine generally more potent than phenylephrine.
Nasal decongestant sprays offer rapid relief but carry a risk of 'rebound congestion' if used for more than 3-5 days.
Antihistamines are best for allergy-induced congestion, with options ranging from drowsy (diphenhydramine) to non-drowsy (cetirizine, loratadine) formulas.
Nasal steroid sprays are a good long-term solution for chronic inflammation, though they can take several days to reach full effect.
Saline nasal sprays are a safe, non-medicated option for all ages that moisturizes nasal passages and loosens mucus.
Consult a healthcare provider before using decongestants, especially if you have conditions like high blood pressure, heart disease, or glaucoma.

Understanding the Cause of a Stuffy Nose

A stuffy nose, also known as nasal congestion, occurs when the blood vessels and tissues inside the nasal passages become swollen and inflamed. This swelling is often a response to an infection (like the common cold or flu) or an allergic reaction. The best medication to relieve a stuffy nose will depend on the root cause of your congestion. Below, we explore the different types of pharmacological options available.

Decongestants: The Primary Relief for a Stuffy Nose

Decongestants are specifically designed to treat the swelling that causes nasal congestion. They work by narrowing the swollen blood vessels in the nose, which helps reduce inflammation and allows mucus to drain more effectively, making it easier to breathe.

Oral Decongestants

Oral decongestants are taken in pill or liquid form and provide systemic relief. The two most common active ingredients are pseudoephedrine and phenylephrine.

Pseudoephedrine (e.g., Sudafed): This is widely considered the more effective oral decongestant, but its sale is restricted to the pharmacy counter due to its potential use in manufacturing methamphetamine.
Phenylephrine (e.g., Sudafed PE): This ingredient is available on pharmacy shelves without restriction, but the U.S. Food and Drug Administration (FDA) has found insufficient evidence that oral phenylephrine is effective as a nasal decongestant.

Topical Nasal Decongestant Sprays

These sprays are applied directly into the nasal passages and offer rapid, localized relief. However, they should be used with caution.

Oxymetazoline (e.g., Afrin): Provides fast and potent relief, but prolonged use can lead to a condition called rhinitis medicamentosa, or rebound congestion. Using for more than 3 to 5 consecutive days is not recommended.
Phenylephrine (e.g., Neo-Synephrine): Another topical option that works similarly to oxymetazoline and carries the same risk of rebound congestion with overuse.

Antihistamines: For Allergy-Related Congestion

If your stuffy nose is caused by an allergic reaction to pollen, dust, or pet dander, an antihistamine may be the right choice. Antihistamines work by blocking histamine, a chemical released by the body during an allergic response that causes swelling, sneezing, and a runny nose.

Types of Antihistamines

Less-drowsy options: Cetirizine (Zyrtec), loratadine (Claritin), and fexofenadine (Allegra) are second-generation antihistamines that generally cause less drowsiness.
Drowsy options: Diphenhydramine (Benadryl) is a first-generation antihistamine known to cause drowsiness, making it a potential option for nighttime relief.
Combination products: Some medications, such as Zyrtec-D or Claritin-D, combine an antihistamine with a decongestant (pseudoephedrine) for dual-symptom relief.

Nasal Steroid Sprays: For Inflammation and Chronic Congestion

For chronic nasal congestion, especially that caused by allergies or inflammation, a nasal steroid spray may be a better long-term solution. They reduce inflammation and immune responses in the nasal passages.

Examples of Nasal Steroid Sprays

Fluticasone (Flonase Allergy Relief): An over-the-counter option that reduces inflammation.
Budesonide (Rhinocort Allergy): Another effective over-the-counter nasal steroid.
Triamcinolone (Nasacort Allergy 24 Hour): Available over-the-counter and provides 24-hour relief.

Nasal steroids may take several days of regular use to reach their full effect, so they are not suitable for immediate, on-demand relief.

Saline Nasal Sprays and Rinses: A Safe, Non-medicated Option

Saline (saltwater) nasal sprays and rinses are a safe and effective way to moisturize dry nasal passages, thin mucus, and flush out irritants. Since they do not contain medication, they can be used as often as needed and are safe for children, pregnant women, and individuals who need to avoid oral decongestants.

Medication Comparison Table


Medication Type	Primary Function	Best For	Relief Onset	Overuse Risk	Common Examples
Oral Decongestants	Shrinks swollen blood vessels systemically	Cold, flu, or sinus pressure-related congestion	Slow (minutes to hours)	Insomnia, increased heart rate, anxiety	Pseudoephedrine, Phenylephrine
Nasal Decongestant Sprays	Shrinks swollen blood vessels topically	Fast, temporary relief for colds	Rapid (minutes)	Rebound congestion (rhinitis medicamentosa)	Oxymetazoline (Afrin), Phenylephrine
Antihistamines	Blocks histamine response	Congestion caused by allergies	Medium (hours)	Drowsiness, dry mouth	Cetirizine (Zyrtec), Loratadine (Claritin)
Nasal Steroid Sprays	Reduces nasal inflammation over time	Chronic allergy or inflammatory congestion	Slow (days to weeks)	Minimal with proper use	Fluticasone (Flonase), Triamcinolone (Nasacort)
Saline Nasal Sprays/Rinses	Moisturizes and flushes nasal passages	General congestion, dryness, and maintenance	Immediate	None; safe for long-term use	Ayr Saline, NeilMed Sinus Rinse

Important Considerations and Home Remedies

Choosing the right medication involves considering your specific symptoms, underlying health conditions, and potential side effects. Always read the product label carefully and consult a healthcare professional, especially if you have chronic conditions like high blood pressure, heart disease, or glaucoma. Pregnant or breastfeeding individuals should also seek medical advice before use.

In addition to medication, several home remedies can provide significant relief:

Stay Hydrated: Drinking plenty of fluids, especially warm ones like soup or tea, helps to thin mucus and promote drainage.
Use a Humidifier or Vaporizer: Adding moisture to the air can soothe irritated nasal passages and loosen mucus, making it easier to clear.
Take a Hot Shower: The steam from a hot shower can help open nasal passages and break up congestion.
Try Nasal Strips: Adhesive strips can be placed on the nose to mechanically open nasal passages, especially helpful at night.

Conclusion

Finding what drug relieves a stuffy nose effectively starts with identifying the cause of your congestion. For short-term relief from a cold, an oral or topical decongestant is the standard. If allergies are the culprit, an antihistamine or nasal steroid spray may be more appropriate. For non-medicated, safe, and long-term relief, saline nasal sprays are an excellent option. For those with underlying health conditions, seeking advice from a healthcare provider is crucial to ensure the safest and most effective treatment. Ultimately, a combination of the right medication and supportive home care can provide significant relief and help you breathe easier.

Frequently Asked Questions

Sudafed contains the active ingredient pseudoephedrine, which is a highly effective decongestant but is sold behind the pharmacy counter due to regulations. Sudafed PE contains phenylephrine, which is available on store shelves, but its effectiveness as an oral decongestant is debated by the FDA.

The U.S. Food and Drug Administration (FDA) recommends avoiding over-the-counter decongestants and cold medicine for children younger than age 4. For children over this age, it's best to consult a pediatrician or pharmacist and follow dosage instructions carefully.

Rebound congestion is a condition that occurs from the overuse of topical decongestant nasal sprays. After a few days of use, the nasal passages swell up more than before, creating a cycle of dependency on the spray. It is recommended not to use these sprays for more than 3-5 days.

Oral decongestants like pseudoephedrine and phenylephrine constrict blood vessels, which can raise blood pressure. Individuals with high blood pressure should avoid these medications or consult their doctor. Safe alternatives include saline sprays or nasal steroid sprays.

Unlike fast-acting decongestants, nasal steroid sprays take time to reduce inflammation. It may take several days to a couple of weeks of regular use to feel the full effects of the medication.

Yes, you can. It's often recommended to use a saline spray first to clear the nasal passages, followed by a medicated spray. However, you should still adhere to the usage limits for the medicated spray to avoid rebound congestion.

You should see a doctor if your stuffy nose persists for more than 7-10 days, is accompanied by a fever, or gets worse after initially improving. These could be signs of a more serious condition, such as a sinus infection.
