Only one: Aldurazyme.
Laronidase and breastfeeding
From LactMed, the US National Library of Medicine’s Drugs and Lactation Database — quoted, not rewritten.
Full LactMed record for laronidase: levels in milk, effects in breastfed infants, and the drugs it would consider insteadLimited information from on mother receiving laronidase for mucopolysaccharidosis type I indicates that the drug is not detectable in breastmilk and her breastfed infant suffered no adverse reactions or adverse developmental effects from the drug in milk. The lack of penetration into milk is consistent with its high molecular weight of 82,000 Da. If laronidase is required by the mother, it is not a reason to discontinue breastfeeding. Until more data are available, laronidase should be used with careful monitoring during breastfeeding.

What people report to the FDA about laronidase
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 865 reports naming laronidase, and the FDA flagged 64% of those reports as serious. The effects reported most often — leaving out reports about overdose, misuse or the condition being treated, which dominate the raw list for common medicines:
- pyrexia129 reports
- inappropriate schedule of product administration61 reports
- cough54 reports
- pneumonia54 reports
- fatigue51 reports
- malaise46 reports
- covid-1944 reports
- dyspnoea42 reports
Read these as a signal, not a rate. A report does not mean laronidase caused the effect — anyone can file one, and many describe people taking several medicines for several conditions. Crucially there is no denominator: FAERS does not record how many people took the drug, so these counts cannot be turned into “X% of patients” — a bigger number often just means a more widely used or more talked-about drug. Duplicates exist, and publicity drives reporting. For what is actually established, read the FDA label.

Frequently asked questions
Can you take laronidase with other medicines?
It depends on the medicine. We check it against the FDA labels rather than guessing: our interaction checker searches each drug's own label for the other and quotes what it says, naming the section it came from. Run laronidase against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.
What forms does laronidase come in?
Across the brands we track, laronidase is currently marketed as injectable, per the FDA's National Drug Code Directory. Each form is dosed differently — follow the label for the exact product you were prescribed.
Is there a generic laronidase?
We do not currently list a generic-labelled laronidase product. That does not always mean none exists — it means none appears under a generic name in the FDA data we track. Ask your pharmacist.
