Abstract
Drug–induced parotitis is a relatively uncommon adverse drug reaction. Most of the data on drug–induced parotitis consist of isolated case reports with few attempts at rechallenge to confirm the aetiology. Phenylbutazone and oxyphenbutazone have a significant number of reports suggesting that these drugs may be implicated in causing parotitis. Antipsychotics, particularly thioridazine, have been associated with parotitis. Most of these reports relate the anticholinergic oral drying as a predisposing factor in the development of a parotid gland infection. There is inadequate literature on the histamine (H2) receptor blockers, interferon–α, doxycycline, trimipramine, nifedipine, methyldopa, nitrofurantoin, nicardipine, isoproterenol or rito–drine to link them as aetiological agents in the development of parotitis.
