Taking Prozac during the third trimester can cause problems in the baby known as Neonatal Adaptation Syndrome (NAS). The symptoms may include crying, irritability, increased muscle tone, jitteriness, breathing problems, shivers, and trouble eating. In most cases, these remain mild and vanish within weeks without needing any treatment or supportive care while most babies may not get affected at all.

It lacks the evidence. However, one study found that it increases the chances of premature delivery, neonatal care, and low birth weight in the third trimester. Women who stopped it by the end of the second trimester faced no problems at all. However, another study lacked the findings.

According to some studies, prematurity and several other complications may relate to the maternal depressive disorder other than the medication. One study showed that babies whose mothers took SSRIs during the second-half trimester had a slightly higher chance of Pulmonary Hypertension (a severe lung problem) however, the overall risk was low.

Should I Stop Taking Prozac?

It is essential to discuss any risks and benefits associated with Fluoxetine before the dosage. As per studies, if the depression misses the treatment, it may result in complications like miscarriage, preeclampsia, preterm delivery, postpartum depression, and low birth weight

Will It Affect The Development And Behavior?

Prozac changes the chemical levels in the brain which may also affect fetal development. Some studies watched the growth from 16 months to 7 years of age and didn’t find any difference. According to One of these studies, the untreated depression may affect the IQ. However, more evidence is required to know the specific effects.

Can I Take It When Breastfeeding?

Norfloxacin and Fluoxetine are present in the breast milk. However, the amount that transfers to the baby is less than 10% of the total amount in the blood of the mother.

Several studies have found no problems when breastfeeding, but some instances reported irritability, vomiting, diarrhea, and lack of sleep. One study found a slight weight loss after having Prozac. However, it’s not a matter of concern.

Mothers who took it while breastfeeding showed no different results on the neurodevelopmental tests. More studies are missing proof of the long-term effects. Those less than two months of age might have a side-effect rather than older ones. See for any side-effects while breastfeeding and report to the pediatrician soon.

  • It causes Premature birth, low birth weight, stillbirth, and sudden infant death syndrome but lacks the evidence.

What If The Father Takes Prozac?

There are no studies as of now looking for risks in the father, but in general, the exposure may unlikely increase the dangers. Having major depression makes it difficult to cope up after the delivery however the severe side-effects are rare. It’s better to consult a doctor soon to treat such a condition as quickly as possible.


The First Trimester (1-3 months)

Few studies are pinpointing the problems with Prozac in an early trimester. Women using the drug are not likely to develop the risk of malformations in the baby. However, there may be other risks like miscarriage and the heart defects due to high dosage.

Second and Third Trimester (4-9 months)

A slow growth rate can result from a case of depression which lacks the treatment. Prozac will become less effective due to the fast changes in the body needing an increase in the dosage. The high dosages can often lead to high BP in the third trimester requiring immediate medical intervention.

Delivery Time

  • Taking the dosage after 20 weeks can develop persistent Pulmonary Hypertension (PPHN) with breathing difficulties.
