Why is this medication prescribed?
Varenicline nasal spray is used to treat the signs and symptoms of dry eye disease (an eye disorder in which tears do not provide sufficient eye lubrication). Varenicline is in a class of medications called cholinergic agonists. It works by activating nerve endings in your nose resulting in increased production of tears in the eyes.
How should this medicine be used?
Varenicline comes as a liquid to spray in the nose. Varenicline usually is sprayed in each nostril twice daily, about 12 hours apart. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use varenicline exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.
Do not shake the bottle that contains varenicline nasal spray.
To use the nasal spray, follow these steps:
- Remove the blue plastic cap and safety clip from the nasal spray pump.
- If you are using the nasal spray pump for the first time, you must prime the pump. Hold the bottle upright with the applicator between your forefinger and middle finger and your thumb under the bottle. Point the bottle upright and away from your face. Press your thumb and fingers firmly and quickly against the pump 7 times. If you have not used the nasal spray for more than 5 days, reprime the pump with 1 spray.
- Blow your nose to clear your nostrils if necessary.
- Tilt your head slightly backwards and carefully put the nasal applicator tip into your nostril. Tilt and point the tip towards the top of the ear on the same side as the nostril. Be careful not let the applicator tip touch the inside of your nose.
- Place your tongue on the roof of your mouth and breath in gently through your nose. At the same time, press firmly and quickly down on the pump to release a spray.
- Repeat steps 4 and 5 in the other nostril.
- Wipe the applicator with a clean tissue and replace the blue plastic cap and safety clip on the bottle.
- Each bottle has enough medication for 15 days of treatment.

What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Do not freeze. Discard the bottle 30 days after opening.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
