What causes a hoarse voice with Spiriva?

Spiriva (tiotropium bromide) is a prescription medication used to treat chronic obstructive pulmonary disease (COPD) and asthma. According to the medication's label and various studies, hoarseness is a known side effect of Spiriva, although it is not a common one [1].

How common is hoarseness with Spiriva?

Clinical trials involving Spiriva have reported hoarseness as a side effect in a small percentage of patients. In one study, hoarseness was reported by approximately 2.5% of participants [2]. Another study found that 1.1% of patients taking Spiriva experienced hoarseness [3].

Why does Spiriva cause a hoarse voice?

The exact mechanism of how Spiriva causes hoarseness is not fully understood. However, it is thought that the medication's direct effect on the muscles in the larynx (voice box) may contribute to hoarseness [4]. Additionally, Spiriva may cause dryness in the mouth and throat, which can also lead to hoarseness.

Duration of hoarseness with Spiriva

The duration of hoarseness associated with Spiriva is generally short-term and may resolve on its own without treatment. According to the medication's label, hoarseness is usually mild and temporary [1].

Alternative treatments for COPD and asthma

If you are concerned about the risk of hoarseness with Spiriva or experience persistent hoarseness while taking the medication, consult your doctor about alternative treatments for COPD and asthma. Other medications, such as inhalers or oral medications, may be available to help manage your symptoms [5].
