Nervous system side effects have included headache in approximately 7% of treated patients. Usually, loratadine (the active ingredient contained in Tavist ND) has not been shown to cause significant drowsiness, sedation, or impair psychomotor skills.[Ref]
One study of second generation antihistamines reported cetirizine was 3.5 times more likely and acrivastine 2.8 times more likely to result in sedation than loratadine. There was no significant difference in incidence of sedation between loratadine and fexofenadine.[Ref]
One study reported prolongation of the QT interval when larger than recommended (20 mg per day) doses of loratadine (the active ingredient contained in Tavist ND) were administered with nefazodone (300 mg every 12 hours).[Ref]
Cardiovascular side effects have included hypertension, hypotension, palpitation, supraventricular tachyarrhythmias, syncope and tachycardia.[Ref]
Gastrointestinal side effects have included rare reports of nausea and dry mouth.[Ref]
Hepatic side effects have included rare reports of jaundice, hepatitis, and hepatic necrosis.[Ref]
Two cases of necroinflammatory liver injury have been reported in patients taking loratadine. One case presented within 2 weeks of starting loratadine therapy and the other occurred 14 months after the start of therapy. Liver transplantation was necessary in one patient.[Ref]
Dermatologic side effects have included a case report of a fixed drug eruption.[Ref]
