Sodium Phenylbutyrate and Taurursodiolpronounced as (soe' dee um fen" il bue' ti rate and taur ur" soe dye' ol )
Why is this medication prescribed?
Sodium phenylbutyrate and taurursodiol is used for the treatment of amyotrophic lateral sclerosis (ALS, Lou Gehrig's disease; a condition in which the nerves that control muscle movement slowly die, causing the muscles to shrink and weaken). Sodium phenylbutyrate is a histone deacetylase inhibitor. Taurursodiol is a bile acid. It is not known exactly how the combination of sodium phenylbutyrate and taurursodiol works, but it may reduce the breakdown and death of nerve cells associated with the worsening of ALS symptoms.
How should this medicine be used?
Sodium phenylbutyrate and taurursodiol comes as a powder to be mixed with water and taken by mouth or through a feeding tube. It is usually taken before a snack or a meal one time a day for 3 weeks then twice a day thereafter. Take sodium phenylbutyrate and taurursodiol at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take sodium phenylbutyrate and taurursodiol exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Open 1 packet and place contents into a cup of 8 ounces of room temperature water and stir vigorously. All of the medication mixed in water must be administered within 1 hour if stored at room temperature. Any medication that remains after that, must be thrown out.
Sodium phenylbutyrate and taurursodiol controls ALS but does not cure it. Continue to take sodium phenylbutyrate and taurursodiol even if you feel well. Do not stop taking sodium phenylbutyrate and taurursodiol without talking to your doctor.

Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
- if you are taking aluminum-based antacids such as Mylanta, Maalox, or AlaMag, talk to your doctor about using a different antacid as these medications can interfere with the absorption of sodium phenylbutyrate and taurursodiol.

- tell your doctor if you have heart failure, high blood pressure, or kidney disease. Sodium phenylbutyrate and taurursodiol contains 928 mg of sodium and so people with these disease states may need to restrict sodium intake from their diet while receiving sodium phenylbutyrate and taurursodiol.

What should I know about storage and disposal of this medication?
Store packets out of reach of children. 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
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.
