Key clinical message: Patients presenting with acute sialadenitis need careful review of their medications. Azathioprine is one of such drugs, which can rarely induce acute sialadenitis. Prompt discontinuation of the medication leads to reversal of the patient condition.
Abstract: Acute sialadenitis is one of the rare adverse effects of azathioprine. We report a case of acute submandibular sialadenitis following initiation of azathioprine which resolved upon discontinuation of the drug.
Keywords: acute sialadenitis; adverse effect; azathioprine; drug induced.
