What Zurzuvae is and what it is used for

What Zurzuvae is

Zurzuvae is an antidepressant medicine used to treat postnatal depression. It should be taken after giving birth by adults aged 18 years or older.

What Zurzuvae is used for

Postnatal depression is depression that begins during pregnancy or soon after giving birth.

Symptoms can include low mood or sadness, sleep disturbances, changes in weight, difficulty in concentrating, feelings of worthlessness, loss of interest in favourite activities, and feelings of being slowed down or anxiety.

Postnatal depression may interfere with the mother-baby relationship and have serious effects on the newborn baby and other family members.

How Zurzuvae works

Zurzuvae increases the activity of GABA (gamma-aminobutyric acid) on receptors in the brain. GABA is involved in the regulation of mood. By increasing the activity of GABA, Zurzuvae may help the parts of the brain affected by depression. Typically, symptoms start to improve by the third day of the 14-day Zurzuvae treatment course.
