Help I Have Allergies (loratadine) Disease Interactions
There is 1 disease interaction with Help I Have Allergies (loratadine):
Loratadine (Includes Help I Have Allergies) ↔ Renal/Liver Disease
Moderate Potential Hazard, High plausibility
Applies to: Renal Dysfunction, Liver Disease
Loratadine is primarily converted by the liver to an active metabolite, and both parent drug and metabolite are excreted in the urine. Patients with renal and/or liver disease may be at greater risk for adverse effects from loratadine due to drug and metabolite accumulation. The manufacturer recommends one-half the regular dosage initially in patients with liver failure or decreased renal function (GFR < 30 mL/min). Due to the differential effects of hepatic impairment on the serum half-life and clearance of loratadine and pseudoephedrine, the use of products containing a fixed combination of these drugs is not recommended in the presence of liver failure.
