Frequently asked questions

Why is linezolid called a reserve antibiotic?

It is kept for resistant infections like MRSA so bacteria do not become resistant to it as well.

Why do I need blood tests?

Linezolid can lower blood counts, especially with longer courses, so doctors check your blood regularly.

Are there foods I should avoid?

Large amounts of aged or fermented foods rich in tyramine (strong cheeses, soy sauce, cured meats) can raise blood pressure. Ask your doctor or pharmacist for a list.
