Nasal sprays are used to deliver medications into your nostrils. Most often, they are used to treat allergy or cold symptoms, such as:

  • Itching
  • Sneezing
  • Nasal congestion

Some nasal sprays, however, deliver medications that act elsewhere in the body. The lining of your nose is rich in blood vessels. This means it can easily absorb medications into your bloodstream.

Depending on the medication, nasal sprays are available by prescription or over-the-counter (OTC). Most come in a hand-operated pump bottle or squeeze bottle. They work by introducing a fine mist of the medication into your nostrils.

This article looks at the different types of nasal sprays and how to use them. It also discusses potential side effects.

Types of Nasal Sprays

There is a wide variety of OTC and prescription nasal sprays on the market. Some treat nasal congestion and allergies. Others deliver medications and vaccines to manage or prevent illness. The first step in correct nasal spray use is making sure you are using it for the right reasons.

Basics of Nasal Spray Use

Many different medications come as nasal sprays, and instructions for how to use them can vary. If you don't understand the instructions for the particular product you're using, ask your pharmacist to walk you through them.

Before starting:

  • Make sure you can breathe through each nostril. If your nostril is blocked, the medication won't go deep enough into the nasal passage to be effective.
  • Know that some nasal sprays need to be primed each day before use. To do so, squirt it a few times into the air until a fine mist comes out. Make sure to keep it away from your eyes and others.
  • Store your nasal spray as directed and keep the bottle away from direct sunlight. Don't share your nasal spray with other people and, most importantly, keep it where children can't get to it.

When you're ready to use the spray, remember to sniff gently as if smelling your favorite food or a flower. Do not snort the spray, which can cause the medication to bypass your nasal passage and go straight into your throat.

Step-by-Step Instructions

To use a pump-bottle nasal spray correctly:

  1. Blow your nose gently to remove mucus from your nasal passages.
  2. Wash your hands with soap and water.
  3. Gently shake the bottle of nasal spray and remove the cap. If needed, prime the dispenser before using it.
  4. Tilt your head slightly forward and close one nostril by gently pressing against the side of your nose with your finger.
  5. Insert the tip of the nasal spray into the other nostril. Point the tip toward the back and outer side of your nose. Make sure to direct the spray straight back, not up into the tip of your nose.
  6. Squeeze the nasal spray bottle as you slowly breathe in through your nose.
  7. Remove the tip of the nasal spray from your nostril and breathe out through your mouth.
  8. Repeat this procedure for your other nostril (if advised). Make sure to follow the directions and use only the recommended amount of medication.
  9. Wipe the tip of the nasal spray with a tissue or alcohol pad and put the cap back on.
  10. Try to avoid sneezing or blowing your nose immediately after using the nasal spray.

If you're using your nasal spray correctly, the medication should not drip from your nose or down the back of your throat.

Some nasal sprays leave an unpleasant taste in your mouth. A drink of water or juice should help eliminate the aftertaste.

Never use your nasal spray after the expiration date on the bottle. Liquid medication can easily be contaminated with dirt or bacteria.

Side Effects

Nasal sprays can cause side effects. Some common ones include:

  • Burning
  • Bleeding
  • Stinging
  • Increased runny nose
  • Dryness in the nose
  • Sneezing
  • Nervousness
  • Nausea
  • Headache

If any side effects are persistent or severe, let your healthcare provider know. Also contact your healthcare provider if you experience any of the following more significant side effects:

  • Dizziness
  • Insomnia
  • Tremors
  • Vision changes
  • Weakness
  • Shortness of breath
  • Irregular or rapid heartbeat

Rebound Congestion

Vasoconstriction is the narrowing of blood vessels in the nose, which is what helps decrease congestion and fluid release. It is what makes vasoconstrictive nasal sprays, such as Afrin and neosynephrine, beneficial.

With regular use of such sprays over time, however, you'll need increasing dosages to relieve your stuffiness. The overuse of such sprays decreases their effectiveness and can actually make nasal obstruction worse—what's known as rhinitis medicamentosa, or rebound congestion.

As a rule, never use a decongestant nasal spray for longer than three days. Overuse can lead to dependence and require you to use a metered-dose device called a Rhinostat to gradually wean you off the medication.
