The following information is a guide only,  a doctor may want to try dosages outside these recommended guides.

Form: Tablets.

When: At any time of day, although recommended you stick to the same time every day. If you have trouble sleeping, it’s best to take the medication in the morning.

Child dose: The usual dose for children aged 6-12 is 25mg daily but this may be increased to 50mg. For children aged 13-17 the usual dose is 50mg daily.

Adult dose: The usual dose for adults is 50mg daily, as a single dose,  however, it may be started at a lower dose and gradually increased at 50mg intervals to a maximum dose of 200mg a day.

Older people: Please consult your doctor.

Half-Life: It’s thought to be approximately 26 hours (but ranges between 22-36 hours). If you occasionally forget to take a dose, because of the long half-life don’t worry, take your next dose the next day at the usual time. Never take two doses at the same time to make up for a forgotten one.

Drug interactions: Don’t take St John’s wort, the herbal remedy, while you are taking Sertraline as this will increase your risk of side effects.

Pregnancy and Breast Feeding: It’s important for you and your baby that you stay well during your pregnancy. If you become pregnant while taking Sertraline speak to your doctor, it’s important not to stop taking your medicine unless your doctor tells you to.  Ask your doctor to discuss the potential benefits against potential risks of staying on medication whilst pregnant or breastfeeding so that you can make an informed choice about what is right for you and your baby.  NHS Choices report that if your doctor or health visitor says your baby is healthy, Sertraline is one of the preferred antidepressants to take when breastfeeding because despite Sertraline passing into breast milk in tiny amounts, its only been linked with side effects in a very few breastfed babies.

The NICE guidelines, published in 2005, reported that Sertraline has a UK marketing authorisation for treating OCD in children aged 6 years and older.
