3. Assess orthostatic vital signs before
initiation of the therapy.
4. Instruct the patient to take drug with
meal.
79. EFFECTS OF MATERNAL MEDICATIONS
ON FETUS & BREAST FEEDING INFANTS
1. During early embryogenesis, the drugs taken by the
mother reach the conceptus through the tubal/ uterine
secretions by diffusion.
2. The harmful effect on the blastocyst is usually death, in
case of survival there is chance of congenital anomalies
3. From 2nd-12th week (period of organogenesis) drugs can
cause serious damages
4. Gross congenital malformations & even death of the
fetus may result, depending on route, length of time & dose
of exposure
80. 5. From 2nd trimester transfer of drugs takes place
through the utero-placental circulation due to lowered
serum albumin concentration which results from
haemodilution
6. As the albumin binding capacity of the drugs is
decreased more free drug is available for placental
transfer
7.The metabolism of the drug may be hampered by the
increase in plasma steroids, increased utero-placental
blood flow, increased placental surface area & decreased
thickness of placental membrane are the additional
cause for increased drug transfer
8. Fetotoxic/ teratogenic drugs are prescribed only when
the benefits out weigh the potential risks. Prior
councelling is mandatory & minimum therapeutic dosage
is used for shortest possible duration
81. Maternal medications with established
teratogenic properties & their effects
1.Cytotoxic drugs: multiple fetal malformations &
abortion
2.Androgenic steroids, hydroxy progesterone:
masculinization of the female offspring
3.Lithium: increased congenital malformations when
used in the 1st trimester, neonatal goitre, hypotonia
& cynosis
4.Diethyl stillbestrol: vaginal stenosis, cervical
hoods & uterine hypoplasia in female fetuses.
82. Maternal drug intake & breastfeeding
Maternal drug intake of nursing mothers have adverse
effects on lactation & also on the baby as it may be
present on the breast milk
• Transfer of drugs through breast milk depends on the
following factors:
• Chemical properties
• Molecular weight
• Degree of protein binding
• Ionic dissociation
• Lipid solubility
• Tissue pH
• Drug concentration
• Exposure time
83. Drugs identified as having effects on
lactation & the neonates are listed below:
• Bromides: rash, drowsiness, poor feeding
• Iodides: neonatal hypothyroidism
• Chloramphenicol: bone marrow toxicity
• Oral pill: suppression of lactation
• Bromocriptine: suppression of lactation
• Ergot: suppression of lactation
• Metronidazol: anorexia, blood dyscrasias,
weakness, neurotoxic disorders
85. CONCLUSION
• No drug should be administered to a woman during
pregnancy, labor and birth, unless the woman is fully
informed of the known risks and the relevant areas of
uncertainty regarding the effects of the drug on the
physiologic and neurologic development of the woman
or her baby
• The drugs that are used daily in obstetric can have a
huge impact on the outcome of both mother and child.
• Therefore, obstetric providers need to have a very clear
understanding of the mechanism of action, doses and
side-effects of the most commonly used drugs.
