Effects of medications on the voice

Professional singers often present a difficult diagnostic dilemma concerning their medication use. Most drugs are never formally evaluated for effects on the voice and finding details of rare side effects can be time consuming for the practitioner. Common use of over-the-counter medication and herbal remedies, combined with the interaction of prescription medications used to treat other medical conditions, can cause many physical and psychologic inter-actions in patients that may not intuitively relate to medication use. Some side effects and interactions may be managed easily, whereas others may be much more severe. An open communication with the patient and knowledge of these issues can be helpful in the management of professional voice users.
