Side-effects of longer-term Use (Caution):
Long-term use, however, can have serious side-effects, particularly when used for more than two weeks. Myelosuppression may occur causing Thrombocytopenia.. Accordingly, when longer than two weeks use is necessary, platelet counts should be checked every week, at least once.

Linezolid is expensive, costing around US$100 per pill in the United States and most first-world countries. However, it appears to be more cost-effective than similar antibiotics, such as vancomycin, as it can be switched from intravenous to oral dosing when a patient is stable enough, without the need for dose adjustments, and enabling the patient to go home if applicable.
