Antidepressants and pregnancy what choices for women?

Women taking antidepressants can be faced with a difficult choice when pregnant.  Many women are reluctant to take medication during pregnancy and feel the need to choose ‘between the drug and the baby’. Data shows that the majority of women stop taking such medicines abruptly on becoming pregnant.  But is this the best approach, particularly when the majority (70%) will relapse on stopping the medication?  

So, should women stop taking the medication on becoming pregnant?  Certainly, there isn't a 'one size fits all solution'.  But women need to be supported in whatever decision is made.  This is why professional bodies such as  The Royal College of Obstetricians and Gynaecologists (RCOG) in the UK  recommend a pregnancy management plan worked up for an individual with a multidisciplinary support team.  We need more understanding of the mental health issues involved in a pregnancy. 

The consequences of stopping medication can be severe.  Mental health relapse can lead to suicidal risk, puerperal psychoses and an unstable emotional connection between the mother and the child.  Postpartum psychosis (or puerperal psychosis) is a severe mental illness starting suddenly in the days, or weeks, after having a baby. Symptoms vary and can change rapidly. They can include mood swings, depression, confusion,  as well as hallucinations and delusions. 

A new study confirms there are no easy answers, but stresses the need to work with women both during and after pregnancy.  Approximately 10% of pregnant women will experience clinically significant depressive symptoms during pregnancy.  Women with a history of major depression are considered at risk of a recurrence during pregnancy if medication is stopped.  A major study in 2006 found that women who discontinued antidepressant medication during pregnancy relapsed significantly more frequently during their pregnancy than those who continued their medication.  Nor is depression during pregnancy without consequences for babies.  Studies have also shown that children born to depressed mothers are more likely to have behavioural problems or problems in cognitive and emotional development.  

In an analysis of women who started pregnancy when taking antidepressant medications, investigators found three pathways of antidepressant dispensing during pregnancy: more than half stopped their treatment, a quarter maintained their treatment throughout pregnancy, and one-fifth discontinued it for a minimum of three months, resuming it during the postpartum period.

The researchers noted that no sociodemographic or medical characteristics were associated with any particular approach.  Women who continued antidepressant treatment tended to have more frequent obstetric complications and postpartum psychiatric disorders. Among women who interrupted treatment, prescription of benzodiazepines and anti-anxiety drugs, such as valium and Xanax,  decreased initially but rose after birth to a higher level than before pregnancy.


"Monitoring the pregnancy of women taking antidepressants requires a lot of attention. It is important to assess the appropriateness of treatment at the time of pregnancy announcement and to monitor for psychiatric symptoms throughout pregnancy when treatment has been stopped,” said senior author Dr Catherine Laporte, of the Universit√© Clermont Auvergne, in France. “General practitioners are very often called upon for non-obstetric health problems during pregnancy, so they must be made aware.”

What is clear is that following guidelines issued by professional bodies such as the RCOG have improved outcome for both mothers and babies.  There isn't a unique solution that works for all women. Depression during pregnancy is complex and challenging to treat. When antidepressants are stopped at the beginning of pregnancy, patients should be reassessed to identify those who will experience a relapse their mental health problems, and manage them differently to prevent an over‐prescription of medication.

Ian Duncan-Smith says he wants to make those on benefits 'better people'!

By any account, the government's austerity strategy is utilitarian. It justifies its approach by the presumed potential ends. It's objective is to cut the deficit, but it has also adopted another objective which is specifically targeted. It seeks to drive people off benefits and 'back to work'.  The two together are toxic to the poorest in society. Those least able to cope are the most affected by the cuts in benefits and the loss of services. It is the coupling of these two strategic aims that make their policies ethically questionable. For, by combining the two, slashing the value of benefits to make budget savings while also changing the benefits system, the highest burden falls on a specific group, those dependent on benefits. For the greater good of the majority, a minority group, those on benefits, are being sacrificed; sacrificed on the altar of austerity. And they are being sacrificed in part so that others may be spared. Utilitarian ethics considers the ba

A time for every purpose

All life moves. Or, more precisely, all life moves purposefully.  This is true even for trees and plants.  Movement is essential for maintaining life.  Animals migrate; plants disperse.  Some form of migration is an ingredient of all life.  For many organisms, it is a key function of reproduction.  We don't reproduce merely to create a new organism, but also to disperse the population - finding new fertile ground, or resources. Reproduction is a form of migration. Reproduction isn't merely to replicate. Reproduction produces change and diversity.  While we may have strong resemblences in families, we also have differences.  Creating a difference is how evolution works.  In this sense, nature is a continuous exploratory process, finding what works best.  Nature senses change and responds.  Some of this is immediate and physiological or behavioural; some of it is over generations.  If we look at a forest over long periods of time, we would see that it shifts. There is a movement

A weaver's tail - the harvest mouse

Living in the grass is a tiny mouse: the tiny harvest mouse, with a wonderful scientific name that sounds like the title of a Charles Dickens Novel,  Micromys minutus.   It is the only British mammal with a prehensile tail. It uses its tail to hold on to the slender grass stems, at the tops of which it builds a nest. Photo: Nick Fewing These tiny mammals (just around 5 cm long) build a spherical nest of tightly woven grass at the top of tall grasses, in which the female will give birth to about six young.  In the fields, we see cows and horses brushing away flies with their tails; often they will stand side-by-side and end-to-end, and help each other.  Two tails are better than one!  In nature, tails are put to good use.  Just as a tight-rope walker uses his pole for balance, so for some species, a tail provides balance. When running, a squirrel uses its tail as a counterbalance to help the squirrel steer and turn quickly, and the tail is used aerodynamically in flight.  But many anima
