What is the most important information I should know about vigabatrin for oral solution? Vigabatrin for oral solution can cause serious side effects, including:

  1. Permanent vision loss:

Vigabatrin for oral solution can damage the vision of anyone who takes it. Some people can have severe loss particularly to their ability to see to the side when they look straight ahead (peripheral vision). With severe vision loss, you may only be able to see things straight in front of you (sometimes called "tunnel vision"). You may also have blurry vision. If this happens, it will not get better.

Tell your healthcare provider right away if you think that your baby is:

All people who take vigabatrin for oral solution:

  • You are at risk for permanent vision loss with any amount of vigabatrin for oral solution.
  • Your risk of vision loss may be higher the more vigabatrin for oral solution you take daily and the longer you take it.
  • It is not possible for your healthcare provider to know when vision loss will happen. It could happen soon after starting vigabatrin for oral solution or any time during treatment. It may even happen after treatment has stopped.

  •   Because vigabatrin for oral solution might cause permanent vision loss, it is available to healthcare providers and patients only under a special program called the Vigabatrin Risk Evaluation and Mitigation Strategy (REMS) Program. Vigabatrin for oral solution can only be prescribed to people who are enrolled in this program. As part of the Vigabatrin REMS Program, it is recommended that your healthcare provider test your (or your child's) vision from time to time (periodically) while you (or your child) are being treated with vigabatrin for oral solution, and even after you (or your child) stop treatment. Your healthcare provider will explain the details of the Vigabatrin REMS Program to you. For more information, go to www.vigabatrinREMS.com or call 1-866-244-8175.

Brain pictures taken by magnetic resonance imaging (MRI) show changes in some babies after they are given vigabatrin for oral solution. It is not known if these changes are harmful.

3. Risk of suicidal thoughts or actions:

Like other antiepileptic drugs, vigabatrin for oral solution may cause suicidal thoughts or actions in a very small number of people, about 1 in 500 people taking it.

Step 1: Start with 1 of the empty cups and the total number of packets you will need for 1 dose.

Step 2: Before you open the packet, tap it to settle all the powder to the bottom of the packet.

Step 3: Use a pair of scissors to cut open the vigabatrin for oral solution packet along the dotted line.

Step 4: Empty the entire contents of the vigabatrin for oral solution packet into 1 of the clean empty cups (see Figure A).

Figure A
  •   Repeat steps 2 to 4 above to open all of the packets needed for 1 dose of vigabatrin for oral solution.

Step 5: Take the second cup and fill it half way with water (see Figure B).

Do not mix vigabatrin for oral solution with anything other than water.

figure-b
  • You will use the larger oral syringe (10 mL) to draw up the water needed to mix with the powder from the packets. You will need 10 mL of water for each packet of vigabatrin for oral solution.
  • For example:
    • If you are using 1 packet of vigabatrin for oral solution, you will need to use 10 mL of water (fill the 10 mL oral syringe 1 time)
    • If you are using 2 packets of vigabatrin for oral solution, you will need to use 20 mL of water (fill the 10 mL oral syringe 2 times)
    • If you are using 3 packets of vigabatrin for oral solution, you will need to use 30 mL of water (fill the 10 mL oral syringe 3 times)

Step 6: Use the 10 mL oral syringe to draw up 10 mL of water. To do this, put the tip of the oral syringe all the way into the water in your cup. Then pull the plunger up towards you until the white ring at the end of the plunger is at the 10 mL line on the barrel of the oral syringe (see Figure C).

figure-c
  • If you see bubbles of air in the oral syringe after drawing up the water, turn the oral syringe so the tip is pointing up (see Figure D ). The air will move to the top of the oral syringe. Pull the plunger back towards you and then push it back gently into the oral syringe to get rid of the bubbles. Tiny bubbles are normal.

Step 10: Slowly push the oral syringe plunger all the way down to empty the water from the oral syringe straight into the cup containing the vigabatrin for oral solution (see Figure F).

figure-f

Repeat steps 6 through 10 until all of the water that is needed to mix 1 dose of vigabatrin for oral solution has been added to the cup containing the powder.

Step 11: Stir the mixture with the small spoon or other clean utensil until the solution is clear (see Figure G). This means that all of the powder is dissolved and ready for use.

figure-g
  • To give a dose of vigabatrin for oral solution to your child, you should use the oral syringe to draw up the total number of mLs of the mixture that your healthcare provider tells you to.
    • If you are giving 3 mL or less of the mixture, use the smaller 3 mL oral syringe.
    • If you are giving more than 3 mL of the mixture, use the larger 10 mL oral syringe (this is the oral syringe that you just used to add the water).

Step 12: Put the tip of the oral syringe all the way into the mixture. Pull the plunger up towards you to draw up the mixture. Stop when the white ring at the end of the plunger lines up with markings on the barrel of the oral syringe that matches the number of mLs of mixture your healthcare provider told you to give (see Figure H).

figure-h
  • If you see bubbles of air in the oral syringe after drawing up the mixture, turn the oral syringe so the tip is pointing up (see Figure I ). The air will move to the top of the oral syringe. Pull the plunger back towards you and then gently push it back in the oral syringe in order to get rid of the bubbles. Tiny bubbles are normal.
figure-i

Step 13: Place the tip of the oral syringe into your child's mouth and point the oral syringe towards either cheek (see Figure J). Push on the plunger slowly, a small amount at a time, until all of the mixture in the oral syringe is given.

figure-j

Step 14: Throw away any mixture that is left over. Do not save or reuse any leftover mixture.
