Detailed Answer:
Hello!

Thank you for asking on HCM!

Regarding your concern I would explain that this medical formulation contains acetaminophen and two other substances ( antihistamine) which help relieve the flu symptoms.

The only possible interaction between warfarin and this medical formulation regards acetaminophen.

Acetaminophen, like other nonsteroidal antiinflammatory drugs can increase the effects of warfarin , but it is not contraindicated to take acetaminophen while on warfarin therapy.

Have you ever tried acetaminophen as a painkiller while on warfarin?

If you have already tried this combination without any adverse effects, there is nothing to worry about.

You can take Nyquil cold &flu, but you should be careful to monitor for any possible bleeding phenomena.

Hope to have been helpful!

Feel free to ask any other questions whenever you need!

Greetings!

Dr.Iliri
