Tinzaparin and breastfeeding
From LactMed, the US National Library of Medicine’s Drugs and Lactation Database — quoted, not rewritten.
Full LactMed record for tinzaparin: levels in milk, effects in breastfed infants, and the drugs it would consider insteadTinzaparin is no longer available in the US. Although tinzaparin has not been studied, other low molecular weight heparins (e.g., dalteparin, enoxaparin) are not excreted into breastmilk in clinically relevant amounts. Tinzaparin is acceptable to use during breastfeeding.

What people report to the FDA about tinzaparin
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 1,050 reports naming tinzaparin, and the FDA flagged 99% 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:
- dyspnoea63 reports
- diarrhoea55 reports
- acute kidney injury49 reports
- maternal exposure during pregnancy41 reports
- renal failure40 reports
- general physical health deterioration38 reports
- pyrexia38 reports
- pneumonia36 reports
Read these as a signal, not a rate. A report does not mean tinzaparin 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 section above.

Frequently asked questions
Can you take tinzaparin 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 tinzaparin 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 tinzaparin come in?
Across the brands we track, tinzaparin 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 tinzaparin?
We do not currently list a generic-labelled tinzaparin 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.
