INTRODUCTIONINTRODUCTION

Page 3: Psychotropic Medications in Pregnancy and Breastfeeding.

The Perinatal Period.The Perinatal Period.

• A uniquely stressful time.

• Pre-existing psychological conditions can be exacerbated by the stresses of the period.

• Many psychological illnesses have an increased risk of onset at this time.

• Whether some psychological illnesses occur uniquely in this period is controversial.

Page 4: Psychotropic Medications in Pregnancy and Breastfeeding.

Some Trends in the treatment of Some Trends in the treatment of Maternal Psychological Illness (1).Maternal Psychological Illness (1).

• maternal age means greater chance of prior treatment of a psychological illness.

• treatment of depression generally in women of childbearing years.

• detection of depression via screening programs (antenatally and postnatally).

• recognition of “PND” beginning antenatally (ie antenatal depression).

Page 5: Psychotropic Medications in Pregnancy and Breastfeeding.

More Trends in the treatment of More Trends in the treatment of Maternal Psychological Illness (2).Maternal Psychological Illness (2).

• concern about the effects of maternal depression/anxiety on an infant’s psychological development.

• use of a wider range of new medications, eg,– atypical antipsychotics– anticonvulsants– new antidepressants– use of medications in combination

Epidemiology of Psychiatric Illness Epidemiology of Psychiatric Illness in Pregnancy.in Pregnancy.

• Pregnancy does not protect against mental illness as was previously thought.

• 5-10% of women have clinically significant psychological symptoms.

• 70% of women with a history of recurrent major depression will relapse during pregnancy.

• 50% of women with untreated Bipolar Disorder will develop an episode in Pregnancy.

Page 8: Psychotropic Medications in Pregnancy and Breastfeeding.

Epidemiology of Postnatal Epidemiology of Postnatal Psychiatric Illness.Psychiatric Illness.

• 2-3 x increased risk of onset of psychiatric illness in the first weeks postpartum.

• Time of greatest risk of psych. hospitalisation for a woman cf any other time in her life.– The risk is as high as 20x

• 10 - 20% of women will develop PND.

• Risk higher if any previous history of illness.

Page 9: Psychotropic Medications in Pregnancy and Breastfeeding.

• previous episode/s of Major Depression, Bipolar Disorder or psychotic illness and considering pregnancy

• currently taking a psychotropic medication and considering pregnancy

• currently taking a psychotropic medication and has become pregnant

• first onset of depression or anxiety disorder during current pregnancy

Clinical Situations Involving Clinical Situations Involving Breastfeeding and Psychotropics.Breastfeeding and Psychotropics.

• previous history of postnatal depression or psychosis requiring prevention (prophylaxis) while breastfeeding

• previous history of depressive illness where postnatal prophylaxis may be advisable

• new onset of postnatal psychiatric illness requiring medication whilst breastfeeding

Page 11: Psychotropic Medications in Pregnancy and Breastfeeding.

Potential Treatments for Maternal Potential Treatments for Maternal Psychiatric Illness.Psychiatric Illness.

• No treatment• Psychotherapy

– Supportive– Cognitive behavioural– Interpersonal– Psychodynamic

• Medications• ECT

Page 12: Psychotropic Medications in Pregnancy and Breastfeeding.

Supportive Psychotherapy.Supportive Psychotherapy.

• has many helpful components.

• information (education), and advice, which is especially relevant to new mothers

• the ventilation of difficult thoughts and feelings,

• support, praise, encouragement and reassurance

• positive focussing,

• all presented in the context of the therapist’s reliability, consistency and continuity of care.

Page 13: Psychotropic Medications in Pregnancy and Breastfeeding.

Psychotherapeutic Management (1).Psychotherapeutic Management (1).

• Some women will only consider psychotherapy.

• Some mild to moderate depression can be contained by this approach.

• It is important to reassure the woman who is “phobic” about medication that you respect their position.

• Ongoing intermittent psychotherapy allows for monitoring and re-evaluation.

Page 14: Psychotropic Medications in Pregnancy and Breastfeeding.

Psychotherapeutic Management (2).Psychotherapeutic Management (2).

• Supportive psychotherapy builds good will with the woman who is for the time being opposed to medication.

• Helps to create a therapeutic alliance that will be needed if the depression worsens.

• Avoid the dichotomy, “Well if you don’t want my medication I can’t help you”. – or “…. I don’t want to see you.”

• Always keep the “door open”.

Page 15: Psychotropic Medications in Pregnancy and Breastfeeding.

General Issues to Consider.General Issues to Consider.

• Mothers and babies elicit strong emotions.• We each bring our own attitudes and values into

the situation - what are they? Be aware of them.• How many patients? One or two or more?

– The mother, – the mother and foetus/baby– the parental couple, – the family

Page 16: Psychotropic Medications in Pregnancy and Breastfeeding.

The Clinical Problem: Defining The Clinical Problem: Defining Exposure (1).Exposure (1).

• We focus on the issue of exposure.

• There are 2 exposures:

1. What will the foetus/baby be exposed to in terms of medication? (in utero & breastfeeding)

2. What will the foetus/baby be exposed to in terms of maternal psychiatric illness? (in utero & breastfeeding)

Page 17: Psychotropic Medications in Pregnancy and Breastfeeding.

The Clinical Problem: Defining The Clinical Problem: Defining Exposure (2).Exposure (2).

• The foetus/baby will be exposed to something. “There is no such thing as non-exposure.” Z. Stowe.

• The foetus/baby will be exposed to medication or psychiatric illness or both.

• Our role is to help the mother and her partner decide which path of exposure is best for them.

Page 18: Psychotropic Medications in Pregnancy and Breastfeeding.

Two Basic Assumptions.Two Basic Assumptions.

1. All medications cross the placenta and also enter breast milk.

2. We do not yet know all the potential risks from medication exposure.

• We talk about the “Risk/Benefit ratio”.

• Risks of treatment vs the benefits of treatment.

• or risks of treatment vs risks of non-treatment.

Page 19: Psychotropic Medications in Pregnancy and Breastfeeding.

The Risk/Benefit Ratio.The Risk/Benefit Ratio.

• The risks associated with medication are fairly fixed even if some of them are as yet unknown.

• The risks associated with maternal psychiatric illness varies enormously for each individual.

• Hence we ask, “What is the risk-benefit ratio for this woman, given her current symptom pattern or what has happened in her previous episodes of illness?”

Page 20: Psychotropic Medications in Pregnancy and Breastfeeding.

Effects on Mother and foetus and/or baby.

• poor compliance with obstetric/medical care

• poor maternal health/nutrition

• abuse of alcohol and cigarettes

• abuse of other substances including over the counter remedies

• suicidality, self-harm, recklessness

• These are potential effects on the foetus via changes in maternal blood chemistry, hormones, catecholamines, immune function etc,

• What happens to the foetus in untreated maternal psychiatric illness?

• What are the long term consequences of untreated maternal psychiatric illness (eg depression) for offspring into childhood, adolescence, etc.

Potential direct effects of Maternal Potential direct effects of Maternal Depression/Stress.Depression/Stress.

• Effects on foetus

– changes in the HPA axis

– lower birth weight

– prematurity

– behavioural teratogenicity

Page 25: Psychotropic Medications in Pregnancy and Breastfeeding.

What has been shown?What has been shown?

• Deleterious effect on obstetric outcome and later infant development.

• Severe Stress and Depression may:– impede foetal growth– smaller head circumference– increased rate of preterm delivery and other

complications– long term behavioural problems in offspring

Page 26: Psychotropic Medications in Pregnancy and Breastfeeding.

The Placenta as a Filter.The Placenta as a Filter.

• In an Ideal World:• the placenta would screen

out any direct ill-effects from maternal psychiatric illness.

• the placenta would block the medication from reaching the baby (or the medication would have no effect on the baby)

Page 27: Psychotropic Medications in Pregnancy and Breastfeeding.

Does the placenta filter out direct Does the placenta filter out direct effects of maternal psych. illness?effects of maternal psych. illness?

• Research to date suggests No.

• Cortisol (stress hormone) levels in the umbilical chord are typically higher than in the maternal serum.

• There are also possible abnormalities in immune function across the placenta.

• Research is difficult because of the obvious confounding effects of the postnatal period.

Page 28: Psychotropic Medications in Pregnancy and Breastfeeding.

Does the placenta filter out effects Does the placenta filter out effects of medication?of medication?

• Yes, to some extent.

• the concentrations of antidepressant medications in the umbilical chord leading to the baby are less than in the maternal circulation

• there is incomplete placental passage of antidepressants

• “As a class of drug, antidepressants cross the placenta less that just about any other drug”.– Z Stowe.

Page 29: Psychotropic Medications in Pregnancy and Breastfeeding.

• As with pregnancy, this depends on the class of medication.

• All psychotropic drugs pass into the breast milk.

• Antidepressants as an example:– various adverse effects reported– mostly non-specific– many studies show no ill effects– contraindicated in premature, low birth wgt, or medically ill

babies.

Adverse Effects of Psychotropics on Adverse Effects of Psychotropics on Breastfeeding. (2)Breastfeeding. (2)

• Anti-anxiety (Anxiolytics)– various adverse effects reported mostly sedation, lethargy,

sleep disturbance and in some instances respiratory depression.

– The risk seems to diminish as the infant matures due to better metabolism gets older.

– Long acting benzodiazepines (eg diazepam Valium) are more likely to build up in the infant.

– Diazepam, lorazepam are secreted at higher levels in breast milk cf. oxazepam.

• Lithium: – contraindicated in most cases– if mother strongly desires can be done with very

close monitoring

• Anticonvulsants – Some adverse effects reported, some quite serious– again can be done if mother strongly desires this and

is made aware of the risks.

Approach to ManagementApproach to Management

•General Principles–Plan Ahead

Page 46: Psychotropic Medications in Pregnancy and Breastfeeding.

Planning AheadPlanning Ahead

Page 47: Psychotropic Medications in Pregnancy and Breastfeeding.

Try to Pre-empt Difficulties.Try to Pre-empt Difficulties.

• Try to discuss the issues prior to pregnancy along with discussion of contraception.

• Planning ahead is the key. This allows time for informed decisions. Have a plan in place based on the “risk-benefit ratio”.

• Try to involve partners and families where appropriate.

• The woman and her partner must ultimately decide what is best for them.

Page 48: Psychotropic Medications in Pregnancy and Breastfeeding.

If Planning a Pregnancy.If Planning a Pregnancy.

• Stop medications, if possible, while attempting conception.– This depends on the persons previous psychiatric

history.

• Stop medications on becoming pregnant– by testing each cycle. – again this depends on the history and should not be

as a matter of routine.

Page 49: Psychotropic Medications in Pregnancy and Breastfeeding.

Approach to Management: Early Approach to Management: Early Pregnancy. (1)Pregnancy. (1)

• Discuss the strengths and weaknesses of each treatment modality.

• Discuss the risks and benefits of the various options - “Risk-Benefit ratio”.

• No decision is risk free.• Try to minimise exposures. • Avoiding all drugs in the first trimester is the

ideal, but this is not always possible.

Page 50: Psychotropic Medications in Pregnancy and Breastfeeding.

Approach to Management: Early Approach to Management: Early Pregnancy. (2)Pregnancy. (2)

• Treat the mental illness as expertly as possible. • Avoid changing medications (this will add a new

exposure).• Stick with medications with good body of

information.• Avoid poly-pharmacy. • Avoid anticonvulsants unless absolutely

necessary and monitor with ultrasound.

Page 51: Psychotropic Medications in Pregnancy and Breastfeeding.

Approach to Management: Later in Approach to Management: Later in PregnancyPregnancy

• Pharmacokinetics can change in pregnancy and doses may need to be changed.

• Use lowest dose but be ready to increase dose or reintroduce a previous medication.

• Discontinuation effects.(Neonatal Withdrawal). Consider gradual reduction of medication and ceasing prior to delivery (controversial).

Page 52: Psychotropic Medications in Pregnancy and Breastfeeding.

How Are Decisions Made? A How Are Decisions Made? A Question of Balance.Question of Balance.

• Decisions are rarely clear cut.

• Usually there are two or more very reasonable options between which the mother and the physician have to chose.

• Some factors lead to one decision, other factors lead to a different decision.

• Weighing the risks is a colaborative process between parents and physician.

Page 53: Psychotropic Medications in Pregnancy and Breastfeeding.

Who Decides and How?Who Decides and How?

• Ultimately it must be a mother’s and partner’s decision.

• This relies on the information we provide but also on her assessment based on:– her values and her choices

– her desires for the future and how she gives weight and meaning to different risks and the different information presented

• There is rarely a “right answer”.

Page 54: Psychotropic Medications in Pregnancy and Breastfeeding.

External Considerations.External Considerations.

• Family pressures

• Partner pressures– doesn’t believe in depression as a diagnosis– doesn’t believe in medications– hasn’t seen an episode of depression yet– doesn’t want her to be like his mother/aunt etc

General guidelines for managing General guidelines for managing Bipolar Disorder in Pregnancy.Bipolar Disorder in Pregnancy.

• Plan ahead and discuss risks.

• Abrupt discontinuation greatly increases relapse in Bipolar Disorder.

• Reduce medications if possible.

• Consider ECT (good safety data in pregnancy)

• Monitor pregnancy closely with ultrasound.

• Consider options for post partum prophylaxis.

Page 80: Psychotropic Medications in Pregnancy and Breastfeeding.

Mild - Moderate Bipolar DisorderMild - Moderate Bipolar Disorder

• Avoid medications in first trimester if possible.

• Gradually taper medication before pregnancy or immediately on discovery of pregnancy.

• Reintroduce mood stabiliser immediately if any deterioration in mood.

• Strongly advise for post partum prophylaxis.

Page 81: Psychotropic Medications in Pregnancy and Breastfeeding.

Severe Bipolar Disorder.Severe Bipolar Disorder.

• Maintain prophylaxis throughout the pregnancy despite dangerousness of medication.

• Consider switching from an anticonvulsant to lithium prior to pregnancy or switching to olanzapine.

If Pregnancy occurs while on an If Pregnancy occurs while on an anticonvulsant.anticonvulsant.

• Foetus has possibly already been exposed at the high risk period for neural tube defects.

• Switching to a different agent increases the number of drugs foetus is exposed to.

• No good options.

• Need full discussion with the woman about what she thinks is best for her. A balancing act depending on the woman’s history of illness.

Page 83: Psychotropic Medications in Pregnancy and Breastfeeding.

Post Partum Management of Post Partum Management of Bipolar Disorder.Bipolar Disorder.

• Prophylaxis is very important in this period.

• Postpartum psychosis has a 4% risk of infanticide and 5% risk of suicide.

• 30 - 40 % of women with untreated Bipolar Disorder will have an episode of post partum psychosis.

Page 84: Psychotropic Medications in Pregnancy and Breastfeeding.

Breastfeeding in Bipolar Disorder.Breastfeeding in Bipolar Disorder.

• Breastfeeding is relatively contraindicated while taking lithium.

• Consider using an anticonvulsant while breastfeeding. The woman would then need to weigh benefits of breastfeeding vs the unclear risks of breastfeeding with an anticonvulsant.

• In this context being on a prophylactic medication should take precedence to breastfeeding.

Antipsychotic drugs.Antipsychotic drugs.

• High potency drugs: eg haloperidol

• Neonatal extra pyramidal signs, are self limiting and resolve.

• No known teratogenicity based on surveillance data.

• Low potency drugs: eg chlorpromazine

• Neonatal anticholinergic symptoms

• ?some teratogenicity not supported by surveillance data.

Page 87: Psychotropic Medications in Pregnancy and Breastfeeding.

Approach to Reducing exposures in Approach to Reducing exposures in Postnatal illness. (1) Newport Postnatal illness. (1) Newport (2002). (2002).

• Document all psychiatric illness exposures (impaired maternal care, alcohol cigarettes drugs etc,)

• If evidence of severe maternal impairment, err towards medication exposure.

• Consider non-medication modalities according to their availability.

Page 88: Psychotropic Medications in Pregnancy and Breastfeeding.

Approach to Reducing exposures in Approach to Reducing exposures in Postnatal illness. (2)Postnatal illness. (2)

• Exposure in breastfeeding is much less than the exposure in utero.

• Hence stick to same medication that the infant has already been exposed to.

• If infant has not yet been exposed, use a medication of previous response for the mother. i.e. Don’t experiment with new medications.

• Use a medication with data.

Page 89: Psychotropic Medications in Pregnancy and Breastfeeding.

Approach to Reducing exposures in Approach to Reducing exposures in Postnatal illness. (3)Postnatal illness. (3)

• Avoid poly-pharmacy. Monotherapy at any dose is preferable to 2 or more medications.

• Reduce infant exposure with pump and dump at 8 - 9 hours.
