Secobarbital is used on a short-term basis to treat insomnia (difficulty falling asleep or staying asleep). It is also used to relieve anxiety before surgery. Secobarbital is in a class of medications called barbiturates. It works by slowing activity in the brain.
Secobarbital comes as a capsule to take by mouth. When secobarbital is used to treat insomnia, it is usually taken at bedtime as needed for sleep. When secobarbital is used to relieve anxiety before surgery, it is usually taken 1 to 2 hours before surgery. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take secobarbital exactly as directed.
Your sleep problems should improve within 7 to 10 days after you start taking secobarbital. Call your doctor if your sleep problems do not improve during this time, if they get worse at any time during your treatment, or if you notice any changes in your thoughts or behavior.
Secobarbital should normally be taken for short periods of time. If you take secobarbital for 2 weeks or longer, secobarbital may not help you sleep as well as it did when you first began to take the medication. If you take secobarbital for a long time, you may also develop dependence ('addiction,' a need to continue taking the medication) on secobarbital. Talk to your doctor about the risks of taking secobarbital for 2 weeks or longer. Do not take a larger dose of secobarbital, take it more often, or take it for a longer time than prescribed by your doctor.
Do not stop taking secobarbital without talking to your doctor. Your doctor will probably decrease your dose gradually. If you suddenly stop taking secobarbital, you may develop anxiety, muscle twitching, uncontrollable shaking of your hands or fingers, weakness, dizziness, changes in vision, nausea, vomiting, or difficulty falling asleep or staying asleep, or you may experience more severe withdrawal symptoms such as seizures or extreme confusion.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
talk to your doctor about the risks and benefits of taking this medication if you are 65 years of age or older. Older adults should not usually take secobarbital to treat conditions other than seizures because it is not as safe as other medications that can be used to treat the same conditions.
Unless your doctor tells you otherwise, continue your normal diet.
Secobarbital is usually taken at bedtime. If you forget to take secobarbital at bedtime, you are unable to fall asleep, and you will still be able to stay in bed for a full night's sleep, you may take secobarbital at that time. Do not take a double dose of secobarbital to make up for a missed dose.
