Most common side effect of inhalational beclomethasone is :
**Core Concept**
Inhalational corticosteroids like beclomethasone are used to treat respiratory conditions by reducing inflammation in the airways. The most common side effect of these medications is related to their systemic absorption and effects on the body.
**Why the Correct Answer is Right**
The correct answer is related to the systemic effects of beclomethasone. Beclomethasone is a potent corticosteroid that can cause systemic effects when absorbed through the lungs. The most common side effect is suppression of the hypothalamic-pituitary-adrenal (HPA) axis, leading to adrenal insufficiency. This is because beclomethasone can cross the blood-brain barrier and affect the HPA axis, leading to decreased production of cortisol.
**Why Each Wrong Option is Incorrect**
**Option A:** Oral candidiasis is a common side effect of inhaled corticosteroids, but it is not the most common side effect of beclomethasone. This option is incorrect because oral candidiasis is more related to the local effects of the medication on the oral mucosa.
**Option B:** Bronchospasm is a common side effect of bronchodilators, not corticosteroids. This option is incorrect because beclomethasone is a corticosteroid that does not cause bronchospasm.
**Option C:** Hiccups are a rare side effect of inhaled corticosteroids, but they are not the most common side effect of beclomethasone. This option is incorrect because hiccups are a rare and not well-documented side effect of beclomethasone.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that the dose and potency of inhaled corticosteroids can affect their systemic absorption and side effects. Beclomethasone is a high-potency corticosteroid, and its use should be carefully monitored in patients with a history of adrenal insufficiency or other systemic diseases.
**Correct Answer: D. Adrenal insufficiency**
