Dosing adjustments of theophylline may be necessary.TrimipramineAdverse Effect: hypertension, cardiac arrhythmias, and tachycardiaClinical Management: The vasoconstriction and other alpha-adrenergic effects of Isoprenaline are substantially enhanced in the presence of Trimipramine.Concomitant use should be avoided. |
