When your nose is running, it can seriously affect your quality of life. Many people turn to nasal sprays for relief. There are several different types of nasal spray available, including decongestant spray.
Congestion is caused by inflammation in your nasal passages. These are the hollow, air-filled cavities inside your nose. Decongestant nasal sprays (DNSs) provide immediate relief by shrinking swollen blood vessels in your nasal passages. This reduces the inflammation and helps you breathe easier.
DNSs are supposed to be used for a maximum of three days. If you use them longer than that, they can cause rebound congestion. Doctors call this rhinitis medicamentosa. It means congestion caused by medication.
People develop a tolerance to DNSs. This means they need to take increasingly larger amounts to achieve the desired effect. Tolerance can lead to physical drug dependence, which is different than drug addiction. You can become dependent on nasal spray, but not addicted to it. Read on to learn more.
A nasal spray is any kind of medication that’s inhaled through the nose. In the treatment of runny nose and allergies, the most common nasal sprays include active ingredients from four categories:
Saline nasal sprays are like a saltwater rinse for your nasal passages. Germs and irritants enter your nose when you breathe. Your nose produces mucus to flush them out. Saline sprays act like mucus, flushing out irritating substances before they cause inflammation. They can also help flush out excess mucus.
Many saline nasal sprays contain preservatives. These preservatives may cause irritation if your nose is inflamed or damaged. However, if your nose is irritated by dry winter air, saline sprays can add healing moisture.
Some nasal sprays contain corticosteroids that help reduce swelling in the nasal passages. Steroid sprays work best for chronic congestion caused by allergies or irritants. Some steroid sprays require a prescription from your doctor, while others are available at your local drugstore. Common brand names include Nasacort and Flonase.
Steroid nasal sprays are safe for long-term use in adults. Side effects include:
- stinging and burning of the nasal passages
- throat irritation
Some nasal sprays contain antihistamines, which work to reduce congestion caused by an allergic immune response.
Sprays containing azelastine (Astelin and Astepro) have proven to be very safe.
Possible side effects of azelastine sprays include:
- bitter taste
- weight gain
- muscle pain
- nasal burning
Most DNSs contain oxymetazoline (Afrin and generic brands). They work by constricting blood vessels in the nasal passages. DNSs are best for colds, flus, or other short-term problems.
When you’re congested, it’s because your nasal passages are swollen. This makes them feel blocked. The swelling leads to increased mucus production, which causes a runny nose. When DNSs shrink blood vessels, they reduce the inflammation and the associated mucus production.
If you use a DNS, you may experience any of the following side effects:
- increased mucus
- dryness in the nose
- difficulty falling or staying asleep
Some side effects can be serious. Call your doctor right away if you experience feeling a faster or slower heartbeat than what’s usual for you.
Rebound congestion refers to the unfortunate phenomenon in which using DNSs for too long causes — rather than prevents — congestion. It’s a subject of some controversy. In fact, many researchers question whether it’s real.
Decongestants shrink the blood vessels in your nasal passages. When the drug wears off, they swell up again. This causes immediate withdrawal congestion.
According to the National Institute on Drug Addiction, there’s a difference between physical drug dependence and addiction. You’re physically dependent on a drug when skipping a dose causes withdrawal symptoms, such as congestion.
Addiction is categorized by intense cravings for a substance and an inability to stop using despite facing negative consequences.
Addiction is a complex disease with many behavioral characteristics. Unless you have intense cravings for nasal spray, you’re probably dependent — not addicted.
What are the signs that you’re overusing nasal spray?
- You’ve been using it longer than one week.
- You’re using it more frequently than directed.
- When you try to stop using it or skip a dose, you get very congested.
The primary symptom of DNS withdrawal is congestion. In addition, it’s likely that whatever initially caused your congestion will return. This is especially true if you have chronic allergies.
You may experience:
- runny nose
- sore throat
- difficulty breathing
- sinus pressure
Use a DNS only as directed. Follow the instructions on the box or the directions of your doctor. Some general guidelines are:
- Don’t use it for longer than three days.
- Use it once every 10 to 12 hours.
- Don’t use more than twice in 24 hours.
DNSs work best for short-term congestion caused by a virus or infection.
The misuse of DNS isn’t an addiction. However, if you’ve been using it for weeks or months, then it’s likely that you have become physically dependent on it. Talk to your doctor about other treatment options, including steroid nasal sprays and oral allergy medications.
