In some individuals, linezolid may cause lactic acidosis, which requires emergency medical help if developed, according to eMedicineHealth. Symptoms of lactic acidosis include muscle pain or weakness, feeling cold or numbness in the arms and legs, difficultly breathing, dizziness, and slow or uneven heart rate. Linezolid also may cause serious side effects that require calling a doctor and include seizures, blurred vision and symptoms of low blood sugar such as headache, irritability and a jittery feeling.

Less serious side effects of rifampin include feeling tired and urine, stools, tears, sweat or saliva that may appear red or orange, states eMedicineHealth. Possible sulfamethoxazole and trimethoprim side effects that do not require immediate medical attention include vomiting, dizziness, ringing in the ears and problems with sleeping.

Due to the development of antibiotic resistance, doctors may treat serious cases of MRSA with two or more antibiotics, explains eMedicineHealth.
