## What is Nasalcrom nasal?

Nasalcrom works by preventing the release of substances in the body that cause inflammation.

Nasalcrom (for the nose) is used to prevent or relieve allergy symptoms such as runny nose, stuffy nose, sneezing, and itching.

Nasalcrom will not treat the symptoms of asthma, sinus infections, or the common cold.

Nasalcrom may also be used for purposes not listed in this medication guide.

## Warnings

Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

## Before taking this medicine

You should not use Nasalcrom if you are allergic to Nasalcrom.

Ask a doctor or pharmacist if it is safe for you to use this medicine if you have other medical conditions, especially:

- wheezing, or breathing problems;

- drug allergies;

## How should I use Nasalcrom nasal?

Use exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.

This medicine works best if used during allergy season, or at least 1 week before you come into contact with things you are allergic to (pollen, dust, pets, etc).

Nasalcrom is usually given as 1 spray into each nostril every 4 to 6 hours. Do not use this medicine more than 6 times in a 24-hour period.

Use Nasalcrom only during times when you are in contact with things that cause your allergy symptoms. Do not use this medicine for longer than 12 weeks in a row without a doctor's advice.

To use the nasal spray:

- Blow your nose gently. Keep your head upright and insert the tip of the bottle into one nostril. Press your other nostril closed with your finger. Breathe in quickly and gently spray the medicine into your nose. Then use the spray in your other nostril.

- Do not blow your nose for at least a few minutes after using the nasal spray.

- If the spray gets in your eyes or mouth or on your skin, rinse with water.

- After using the nasal spray, rinse the tip with hot water or wipe it with a clean tissue and recap. Avoid getting water into the nasal spray tip.

Call your doctor if your symptoms do not improve after 2 weeks of use, or if symptoms get worse.

Do not share nasal medicine with another person. Sharing a nasal spray bottle can allow infections or disease to pass from one person to another.

Store at room temperature away from moisture, heat, and light. Keep the bottle capped when not in use.
