Alavert Disease Interactions

There is 1 disease interaction with Alavert (loratadine).

Moderate

Loratadine (applies to Alavert) renal/liver disease

Moderate Potential Hazard, High plausibility. Applicable conditions: Renal Dysfunction

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.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
