If you use secobarbital while you are pregnant, your baby could become dependent on the drug. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on habit-forming medicine may need medical treatment for several weeks. Tell your doctor if you are pregnant or plan to become pregnant.

Secobarbital can make birth control pills less effective. Ask your doctor about using a non-hormonal birth control (condom, diaphragm with spermicide) to prevent pregnancy.

Secobarbital can pass into breast milk and may cause side effects in the nursing baby. Tell your doctor if you are breast-feeding.

How should I take secobarbital?

Follow all directions on your prescription label. Never take secobarbital in larger amounts, or for longer than prescribed.

Secobarbital may be habit-forming. Never share secobarbital with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it. Selling or giving away secobarbital is against the law.
