What the prescription omega-3 labels state
- Vascepa's label sets the daily dose at 4 grams.[1]
- In Vascepa's outcomes trial of 8,179 patients, 12% on the drug and 10% on placebo had a bleeding event; the label asks prescribers to monitor people also on anticoagulants or antiplatelet drugs.[1]
- Lovaza's label also sets 4 grams a day, says bleeding-time prolongation in trials stayed within normal limits, and says people also taking an anticoagulant or antiplatelet drug should be monitored periodically.[2]
On warfarin: bleeding signs its Medication Guide says need a call right away
- Unusual bruising, meaning bruises that appear without a known cause or grow in size.[3]
- Bleeding from a cut that takes a long time to stop, nosebleeds or bleeding gums.[3]
- Red or black stools.[3]

Questions for the prescriber or pharmacist
- Is my total EPA plus DHA a day a concern with the blood thinner I take?
- Should I pause fish oil before my surgery or procedure, and for how long?
- Would a prescription omega-3 suit my triglycerides better than a supplement?
- Does adding NMN or NR change anything about my bleeding risk?
