What should I discuss with my healthcare provider before using linezolid?
You should not use linezolid if you are allergic to it.
Do not use linezolid if you have used an MAO inhibitor in the past 14 days. A dangerous drug interaction could occur. MAO inhibitors include isocarboxazid, linezolid, methylene blue injection, phenelzine, tranylcypromine, and others.
Tell your doctor if you also take stimulant medicine, opioid medicine, herbal products, or medicine for depression, mental illness, Parkinson's disease, migraine headaches, serious infections, or prevention of nausea and vomiting. An interaction with linezolid could cause a serious condition called serotonin syndrome.
Tell your doctor if you have ever had:
- high blood pressure;
- a thyroid disorder;
- a carcinoid tumor;
- bone marrow suppression or a weak immune system;
- kidney or liver disease;
- pheochromocytoma (adrenal gland tumor);
- diabetes;
- seizures; or
- if you use a catheter.
Tell your doctor if you are pregnant or breastfeeding.
If you are breastfeeding, tell your doctor if you notice diarrhea or vomiting in the nursing baby.
Linezolid liquid may contain phenylalanine and could be harmful if you have phenylketonuria (PKU).
