What does the quinine label say about lovastatin?

Quinine label, drug interactions (prescription label)

Thus, clinicians considering combined therapy of quinine sulfate with atorvastatin or other HMG-CoA reductase inhibitors ("statins") that are CYP3A4 substrates (e.g., simvastatin, lovastatin) should carefully weigh the potential benefits and risks of each medication.

These are the labels' own sentences. PlainMeds does not grade interactions; a pharmacist or prescriber can say what they mean for one person's medicines.
