Why is this medication prescribed?
Revefenacin oral inhalation is used to control wheezing, shortness of breath, coughing, and chest tightness in patients with chronic obstructive pulmonary disease (COPD; a group of diseases that affect the lungs and airways, that includes chronic bronchitis and emphysema). Revefenacin is in a class of medications called anticholinergics. It works by relaxing the muscles around the airways in your lungs which makes it easier to breathe.
How should this medicine be used?
Revefenacin comes as a solution (liquid) to inhale by mouth using a nebulizer (machine that turns medication into a mist that can be inhaled). It is usually inhaled once a day. Inhale revefenacin at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use revefenacin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Always look at revefenacin nebulizer solution before you inhale it. It should be clear and colorless. Do not use the solution if it is colored, cloudy, or contains solid particles, or if the expiration date on the vial has passed.
Do not use revefenacin during a sudden COPD attack. Your doctor will prescribe a short-acting (rescue) inhaler to use during COPD attacks.
Call your doctor or get emergency medical help if your breathing problems worsen, if you have to use your short-acting inhaler to treat attacks of COPD more often, or if your short-acting inhaler does not relieve your symptoms.
Revefenacin controls COPD but does not cure it. Continue to use revefenacin even if you feel well. Do not stop using revefenacin without talking to your doctor. If you stop using revefenacin, your symptoms may get worse.
Before you use revefenacin for the first time, read the written instructions that come with it. Ask your doctor, pharmacist, or respiratory therapist to show you how to use the nebulizer and compressor. Practice using the nebulizer and compressor while he or she watches.
Revefenacin oral inhalation should be used only in a standard jet nebulizer with a mouthpiece connected to an air compressor. Do not swallow or inject revefenacin nebulizer solution. Do not mix the solution with anything else. To inhale the solution using a nebulizer, follow these steps;
- Twist off the top of one vial of revefenacin solution and squeeze all of the liquid into the nebulizer reservoir.
- Connect the mouthpiece to the nebulizer reservoir. Connect the nebulizer to the compressor.
- Sit in an upright, comfortable position. Place the mouthpiece in your mouth or put on the face mask.
- Turn on the compressor.
- Breathe in calmly, deeply, and evenly for about 8 minutes until mist stops forming in the nebulizer chamber.
Clean your nebulizer regularly. Follow the manufacturer's directions carefully and ask your doctor or pharmacist if you have any questions about cleaning your nebulizer.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with revefenacin and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.

What should I know about storage and disposal of this medication?
Keep this medication in the foil pouch it comes in, sealed, and out of reach of children. Do not open the foil pouch until you are ready to use the medication. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
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
