Pregnancy and Phentermine: Understanding the Risks and Timing to Discontinue Use

Phentermine, a prescription medication used for appetite suppression, is a drug that pregnant individuals should avoid. This stimulant, commonly used for weight loss, can potentially pose risks to both the mother and the developing fetus.

According to recent studies, the use of phentermine during pregnancy may increase the risk of shoulder dystocia, a condition where the baby's shoulders get stuck during delivery. Furthermore, the limited body of evidence suggests that phentermine may also increase the risk of complications such as cleft palate and other birth defects.

In a large sample of 30,704 pregnant individuals, 4.9% had an exposure to anti-obesity drugs during pregnancy, with phentermine being the most common drug. If a person has taken phentermine during pregnancy, even unintentionally, they should tell all medical professionals. Pregnant women who have taken phentermine during pregnancy should seek consultation with their healthcare provider immediately to evaluate potential risks to the fetus and receive appropriate medical advice.

Deliberate weight loss during pregnancy is not safe, even in people who are overweight or have obesity. Pregnant women should focus on maintaining a balanced diet and regular exercise instead of resorting to weight loss medications like phentermine.

Because phentermine is a stimulant, and stimulants are potentially harmful to infants and young children, people should generally not take it while nursing. The prescribing insert advises against using phentermine during pregnancy and urges pregnant people to discontinue use of the drug.

On the other hand, a 2021 review found that infants may have a higher birth weight when exposed to anti-obesity drugs during development. However, the same review also found a correlation between phentermine use and thickened mitral valves of the heart and bilateral porencephalic cysts in infants.

Given these findings, it is crucial for people using, or thinking of using, phentermine, who are considering becoming pregnant to ask a doctor about the risks and alternatives. People taking phentermine for weight loss should also consider using contraception to prevent unintended pregnancy.

In conclusion, phentermine is a prescription medication that works by suppressing appetite, but its use during pregnancy and nursing can potentially pose risks to the mother and the baby. Pregnant people should avoid taking phentermine and consult their healthcare provider immediately if they have unintentionally taken it during pregnancy.
