Dr. Reddy’s Laboratories Ltd. has issued a voluntary nationwide drug recall of six specific lots of their medication Sapropterin Dihydrochloride (Kuvan), a prescription drug used to manage Phenylketonuria (PKU) in adults and children.

This drug recall is due to potential decreased potency of the medication in some packets, identified through stability testing and customer complaints.

What is Phenylketonuria (PKU)?

Phenylketonuria (PKU) is a rare inherited metabolic disorder that affects the body’s ability to process the amino acid phenylalanine (Phe).

Untreated PKU can lead to a buildup of Phe in the blood, causing intellectual disability, behavioral problems, and seizures.

How Does Sapropterin Dihydrochloride Work?

Sapropterin Dihydrochloride works by increasing the body’s natural production of a molecule called BH4, which is necessary for processing Phe. This helps to lower blood Phe levels in patients with PKU.

Why Was the Drug Recall Issued?

Dr. Reddy’s initiated the drug recall after discovering discolored powder in some packets of Sapropterin Dihydrochloride.

This discoloration may indicate a decrease in the medication’s potency, meaning it might not be as effective in lowering blood Phe levels.

Potential Risks of Reduced Potency Sapropterin Dihydrochloride

Elevated Blood Phenylalanine Levels: If Sapropterin Dihydrochloride is not working effectively, blood Phe levels may rise in patients. Chronically high Phe levels in infants and children can lead to permanent intellectual disabilities.
Pregnancy Complications: In pregnant women with PKU, high Phe levels during pregnancy are linked to microcephaly (small head size) and congenital heart disease in the developing baby.
