Asthma is a common respiratory condition that can make breathing difficult. If you’ve recently discovered you’re pregnant, you might be wondering whether it’s safe to use montelukast, commonly known as Singulair, during your pregnancy. Research indicates that using montelukast during pregnancy is likely safe for your developing baby. Below is some essential information regarding the use of Singulair while pregnant, which can help you have a more informed discussion with your healthcare provider.
Understanding Montelukast
Montelukast, marketed under the brand name Singulair and produced by Merck & Co, is primarily used for the chronic management and prevention of asthma in adults and children aged 12 months and older. It also helps prevent exercise-induced bronchoconstriction in those 15 years and older and alleviates symptoms of seasonal and perennial allergic rhinitis in patients as young as 2 years old.
Pregnancy Safety Classification: Category B
Recommendation for Use During Pregnancy: Limited human data suggests it is probably compatible.
Possible Side Effects:
- Common (18%): Headache
- Occasional (4%): Influenza
- Rare (2-3%): Pain, cough, dyspepsia, dizziness, fatigue, dental pain, abdominal pain
Key Insights on Montelukast Use in Pregnancy
Here are some important points sourced from reputable references regarding montelukast use during pregnancy:
- According to Briggs, Freeman, and Yaffe, montelukast has not shown teratogenic effects in animals, and adverse outcomes in humans do not indicate a common pattern. Some sources suggest it may be safe during pregnancy; however, these conclusions are primarily based on animal studies. The American College of Obstetricians and Gynecologists has indicated that montelukast can be considered for women with severe asthma who have responded well to the medication before pregnancy.
- The Physicians’ Desk Reference notes that well-controlled studies in pregnant women are lacking. Therefore, montelukast should only be used during pregnancy if absolutely necessary.
- The Reproductive Toxicology Center states that animal studies do not indicate an increased risk for congenital abnormalities. A registry of 203 high-risk pregnancies has not found a syndrome of abnormalities associated with montelukast exposure. However, there have been reports of limb reduction defects, which are mentioned in the drug’s warning label, although no causal link to the medication has been established.
