Your doctor will calculate the dose based on your body weight. You can start with a low dose which your doctor will then gradually increase. Contact your doctor if you are not sure how much to take or if you think your dose needs to be changed.

Taking Epidyolex with food may increase the number of medicines taken up by the body. As far as possible, try to take Epidyolex, in the same way, every day when it comes to meals. Take Epidyolex with or without food every day so that you get the same effect from the medicine every time.

Tell your doctor if you have liver problems as your doctor may need to adjust someone.

How to take Epidyolex orally (by mouth)

The package contains the following

  • A bottle of Epidyolex oral solution
  • A plastic bag with two oral dosing syringes of 1 ml and a bottle adapter
  • A plastic bag with two oral dosing syringes of 5 ml and a bottle adapter

A spare syringe of each size is included in the package in case the first syringe breaks or disappears.

1. Open the bag containing the oral dosing syringe you are going to use to measure dose one.

  • If your dose is 1 ml (100 mg) or less, use the small 1 ml syringe.
  • If your dose is greater than 1 ml (100 mg), use the larger 5 ml syringe.
  • If your dose is greater than 5 ml (500 mg), you must use the larger 5 ml syringe more than once. In this case, you must keep a close eye on how many times you have filled the syringe (eg by dotting each 5 ml dose ) so that you take the correct dose.

You must use the correct dosing syringe to measure dose one. Your doctor or pharmacist will tell you which syringe to use for the prescribed dose. Follow the instructions of your doctor or pharmacist. The bag containing the other syringes and the adapter (ie those you do not need for your dosing ) should be discarded according to the instructions unless your doctor or pharmacist tells you to save both syringe sizes until you have reached your escalated dose.

2. Remove the child-resistant cap from the bottle by pushing it downwards while turning it counterclockwise.

3. Push the bottle adapter firmly into the neck of the bottle. Make sure it is fully inserted. The adapter may come loose and cause suffocation if not fully inserted.

4. Press down on the tip of the dosing syringe you are going to use in the bottle adapter. Leave the syringe in place and turn the bottle upside down.

5. Slowly pull the plunger out of the syringe so that the amount of solution (number of ml) needed is drawn into the syringe. The end of the plunger should be level with the volume marking on the syringe, see the picture.

If there is an air bubble in the syringe, push the liquid back into the bottle, still with the bottle upside down. Then repeat step 5 until the bubble is gone.

6. Turn the bottle over again and carefully remove the syringe from the adapter.

7. Place the syringe tip against the inside of the cheek and gently press on the plunger so that the medicine is sprayed out. Do not press hard on the plunger. Do not aim the medicine far into the mouth or throat.

If dose one is more than 5 ml, repeat steps 4 to 7 for the remaining dose one. Use the 5 ml syringe.

8. Screw the child-resistant cap back onto the bottle firmly by turning it clockwise. The bottle adapter does not need to be removed, the lid fits on top of the adapter.

9. Fill a glass or mug with warm soapy water and clean the dosing syringe by pulling the water in and out using the plunger.

10. Pull the plunger completely out of the syringe body and rinse both parts under the tap. Do not place the dosing syringe in the dishwasher.

Shake off the water from both parts and let them air dry for the next use. Make sure that the dosing syringe is completely dry before using it again, otherwise, it may make the solution look cloudy if water enters the bottle.

If the solution in the bottle has become cloudy, it does not affect its effect. Continue to use the medicine as usual.

If you have taken more Epidyolex than you should, tell your doctor or pharmacist immediately, or contact your nearest emergency department and take the medicine with you. Signs that you have taken more Epidyolex than you should include diarrhea and drowsiness.

If you or your patient have forgotten to take Epidyolex

If you miss a dose, do not take a double dose to make up for a forgotten dose. Take the next dose at the usual time. If you miss many doses, talk to your doctor about which dose you should take.

If you or your patient stop taking Epidyolex
