23-year-old GIRO woman at 10 weeks’ gestation presents to the obstetrics clinic for her initial evaluation. She says she has been hospitalized several times for asthma exacerbations but has never required intubation or admission to an intensive care unit. She is controlled on daily inhaled coicosteroids and albuterol with adequate relief of her symptoms. She Is concerned about taking these medications now that she is pregnant. Which of the following is true regarding asthma medications in pregnancy?

**Core Concept**
Asthma management during pregnancy requires careful consideration of medication safety and efficacy for both mother and fetus. Inhaled corticosteroids (ICS) are a cornerstone in asthma treatment, but their use in pregnancy is a concern due to potential effects on fetal development.

**Why the Correct Answer is Right**
Inhaled corticosteroids, such as beclomethasone, fluticasone, and budesonide, are considered safe for use during pregnancy. They have a low systemic bioavailability due to their inhaled route of administration, which reduces the risk of adverse effects on the fetus. Studies have shown that ICS use during pregnancy does not increase the risk of congenital malformations or other adverse pregnancy outcomes. In fact, ICS use may even reduce the risk of asthma exacerbations and related complications during pregnancy.

**Why Each Wrong Option is Incorrect**
* **Option A:** This statement is incorrect because oral corticosteroids, not inhaled corticosteroids, are associated with an increased risk of congenital malformations and other adverse pregnancy outcomes.
* **Option B:** This statement is incorrect because the use of inhaled corticosteroids in pregnancy is not associated with an increased risk of stillbirth or low birth weight.
* **Option C:** This statement is incorrect because the use of inhaled corticosteroids in pregnancy is not contraindicated; rather, it is recommended as part of asthma management.

**Clinical Pearl / High-Yield Fact**
Inhaled corticosteroids are a safe and effective choice for asthma management during pregnancy. However, it's essential to use the lowest effective dose and monitor maternal and fetal well-being closely.

**Correct Answer: C.**

✓ Correct Answer: C. Both B2 agonist and Inhaled coicosteroids are safe in pregnancy
