Robitussin A-C contains codeine, which is an opioid antitussive that can have sedating effects. One of the major disadvantages of using this medication is the potential for drowsiness as a side effect. This can impair the client's ability to perform tasks that require alertness and can interfere with daily activities.
The other options listed are not the major disadvantage of antitussive therapy with Robitussin A-C:
The medication is irritating to the bronchial tree: Robitussin A-C is primarily used as an antitussive (cough suppressant) rather than for its effects on the bronchial tree. While it may have some mild irritant properties due to certain ingredients, it is not considered a major disadvantage of this medication.
The client may use the medication for 14 days: The duration of use for Robitussin A-C is typically determined by the healthcare provider based on the client's condition. While prolonged use of antitussives is generally not recommended without medical supervision, the duration of use is not considered the major disadvantage of this medication.
The medication is very expensive: The cost of medication can vary, and while cost may be a consideration for some individuals, it is not considered the major disadvantage of Robitussin
A-C specifically. The major disadvantage relates more to the potential for drowsiness caused by the medication.

Nasal glucocorticoids, also known as intranasal corticosteroids, are considered the most effective and recommended first-line treatment for nasal congestion caused by allergic rhinitis or non-allergic rhinitis. They work by reducing inflammation in the nasal passages, relieving congestion, and improving other symptoms such as itching, sneezing, and runny nose.

Leukotriene modifiers, decongestants, and antihistamines can also be used to manage nasal congestion, but they are generally considered second-line options or adjunct therapies.

Decongestants provide temporary relief by constricting blood vessels in the nasal passages, while antihistamines help with symptoms related to allergies. Leukotriene modifiers are primarily used for managing asthma and are not typically the first choice for nasal congestion alone.
