Side effects

When used at therapeutic doses, Dimegan D is well tolerated, however, some patients may experience severe hypertension, headache, vomiting and reflex bradycardia, fatigue, headache, drowsiness, dry mouth, nausea, gastritis, rash, insomnia and rarely alopecia, anaphylaxis or liver disorders with the use of loratadine. Elderly patients are more susceptible to the hypertensive and bradycardial effects of phenylephrine, so they may have reduced cardiac output as a result of sinus bradycardia, increasing the risk of possible heart failure.


In case of overdose, general symptomatic treatment should be started immediately. Patients who took excessive doses of Dimegan D experienced tachycardia, headache and drowsiness. Hemodialysis is not effective.


Concomitant use with ketoconazole, erythromycin and cimetidine may cause an increase in loratadine concentrations. Beta-blockers can increase the vasoconstrictor effects of phenylephrine. MAO inhibitors can prolong and intensify the pressor effects of phenylephrine as well as oxytocin.
