Flonase and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Flonase falls into category C. In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.

Flonase and Lactation

Tell your doctor if you are breastfeeding or plan to breastfeed.

It is not known if Flonase crosses into human milk. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, a choice should be made whether to stop nursing or stop the use of this medication. Your doctor and you will decide if the benefits outweigh the risk of using Flonase.

Priming and Using Your Flonase Nasal Spray

Your Flonase must be primed before you use it for the first time and when you have not used it for a week or more.

How to prime your Flonase Nasal Spray:

  • Shake the bottle gently and then remove the dust cover
  • Hold the bottle with the nasal applicator pointing away from you and with your forefinger and middle finger on either side of the nasal applicator and your thumb underneath the bottle.
  • Press down and release 6 times until a fine spray appears. The pump is now ready for use.

Using your Flonase Nasal Spray:

Step 1. Blow your nose to clear your nostrils.

Step 2. Close 1 nostril. Tilt your head forward slightly and, keeping the bottle upright, carefully insert the nasal applicator into the other nostril.

Step 3. Start to breathe in through your nose, and while breathing in press firmly and quickly down 1 time on the applicator to release the spray. To get a full dose, use your forefinger and middle finger to spray while supporting the base of the bottle with your thumb. Avoid spraying in eyes. Breathe gently inwards through the nostril.

Step 4. Breathe out through your mouth.

Step 5. If a second spray is required in that nostril, repeat steps 2 through 4.

Step 6. Repeat steps 2 through 5 in the other nostril.

Step 7. Wipe the nasal applicator with a clean tissue and replace the dust cover.

Do not use this bottle for more than the labeled number of sprays even though the bottle is not completely empty. Before you throw the bottle away, you should talk to your healthcare provider to see if a refill is needed. Do not take extra doses or stop taking Flonase without talking to your healthcare provider.

Cleaning your Flonase Nasal Spray:

Your nasal spray should be cleaned at least 1 time each week.

1. Remove the dust cover and then gently pull upwards to free the nasal applicator.

2. Wash the applicator and dust cover under warm tap water. Allow to dry at room temperature.

3. Place the applicator and dust cover back on the bottle.

4. If the nasal applicator becomes blocked, it can be removed and left to soak in warm water. Rinse the nasal applicator with cold tap water. Dry the nasal applicator and place it back on the bottle. Do not try to unblock the nasal applicator by inserting a pin or other sharp object.
