Summary
Reteplase is a thrombolytic with a high bleeding risk. Melatonin may slightly influence coagulation in some reports, but any additive effect is theoretical and unlikely to be meaningful.
What this interaction means in plain words
Melatonin and Reteplase have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Possible weak additive effect on hemostasis; mechanism is not well established.
What to do
No change is needed, as reteplase is given in monitored acute settings. Watch for bleeding as standard.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
