• children 1 to 17 years old to improve their ability to exercise, and in children too young to do certain exercise and lung testing.

It is not known if REVATIO is safe and effective in children younger than 1 year of age.

Do not take REVATIO if you or your child:

• take medicines called nitrates.
• take riociguat, a guanylate cyclase stimulator medicine.
• are allergic to sildenafil or any of the ingredients in REVATIO. See the end of this leaflet for a complete list of ingredients in REVATIO.

Before taking REVATIO, tell your healthcare provider about all of your medical conditions, including if you or your child:

• have low blood pressure

Instructions for Use

REVATIO^® (re-VAH-tee-oh)

(sildenafil)

oral suspension

Read this Instructions for Use before you start taking REVATIO oral suspension or giving REVATIO oral suspension to your child and each time you get a refill. There may be new information. This information does not take the place of talking to your healthcare provider about your or your child’s medical condition or treatment.

Important information:

• Ask your healthcare provider or pharmacist to show you how to measure and take or give your child’s prescribed dose of REVATIO oral suspension.
• Your pharmacist will mix (reconstitute) REVATIO oral suspension before it is given to you. Do not take or give REVATIO oral suspension and contact your pharmacist if the medicine in the bottle is still a powder.
• Always use the oral dosing syringe that comes with REVATIO oral suspension. If your carton does not come with an oral dosing syringe, contact your pharmacist.
• Do not take or give REVATIO oral suspension if the bottle adaptor is not in the bottle. If the bottle adaptor is not in the bottle, contact your pharmacist.
• REVATIO oral suspension should not be mixed with any other medicine or flavoring.

Supplies you will need to take or give a dose of REVATIO oral suspension (See Figure A):

• 1 bottle of REVATIO oral suspension with pre-inserted bottle adaptor
• 1 oral dosing syringe (provided in the carton)

Step 1. Shake the bottle of REVATIO oral suspension for 10 seconds before each use. (See Figure B)

Step 2. Remove the cap. Open the bottle by pushing down on the cap and twisting it in the direction of the arrow (counter-clockwise). (See Figure C)

Step 3. Fully push down (depress) the plunger of the oral dosing syringe. Then insert the tip of the oral dosing syringe into the bottle adaptor while holding the bottle upright, on a flat surface. (See Figure D)

Step 4. Turn the bottle upside down while holding the oral dosing syringe in place. Slowly pull back the plunger of the oral dosing syringe until the bottom of the plunger is even with the mL marking on the syringe for your or your child’s prescribed dose. (See Figure E)

If your or your child’s dose of REVATIO oral suspension is more than 2 mL (20 mg), you will need to divide the dose. Follow the instructions given to you by your healthcare provider or pharmacist about how to prepare the divided dose.

If you see air bubbles in the oral dosing syringe, slowly push the plunger all the way up so that REVATIO oral suspension flows back into the bottle and repeat Step 4.

Step 5. Turn the bottle back upright with the oral dosing syringe still in place. Place the bottle on a flat surface. Remove the oral dosing syringe from the bottle adaptor by pulling straight up on the barrel of the oral dosing syringe. (See Figure F) Do not press on the plunger of the oral dosing syringe at this time.

Step 6. Put the tip of the oral dosing syringe into your or your child’s mouth and point it towards the inside of the cheek. Slowly push the plunger of the oral dosing syringe all the way down to give the entire dose. Do not squirt the medicine out quickly. (See Figure G)

If you are giving REVATIO oral suspension to a child, make sure they are in an upright position before giving the medicine.

Step 7. Replace the cap on the bottle, leaving the bottle adaptor in place. Turn the cap in the direction of the arrow (clockwise) to close the bottle. (See Figure H)

Step 8. Wash the oral dosing syringe after each use. Pull the plunger out of the barrel and rinse both parts with water. (See Figure I)

Step 9. Dry all parts with a clean paper towel. Push the plunger back into the barrel. Store the oral dosing syringe with the REVATIO oral suspension bottle.
