linezolid oral Warnings
linezolid oral Uses
Take this medication by mouth with or without food, usually every 12 hours or as directed by your doctor.
The dosage is based on your medical condition and response to therapy. In children, the dosage may also be based on weight, and they may be directed to take this medication every 8 hours.
Linezolid is related to a group of drugs called MAO inhibitors. Certain foods interact with MAO inhibitors, causing severe headache and increased blood pressure. This could lead to a medical emergency. Therefore, it is important to avoid or limit intake of these foods to reduce your risk of these serious problems. (See Drug Interactions section).
Antibiotics work best when the amount of medicine in your body is kept at a constant level. Therefore, take this drug at evenly spaced intervals. To help you remember, take it at the same times each day.
Continue to take this medication until the full prescribed amount is finished, even if symptoms disappear after a few days. Stopping the medication too early may allow bacteria to continue to grow, which may result in a relapse of the infection.
Inform your doctor if your condition persists or worsens.
linezolid oral Side Effects
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor immediately if any of these unlikely but serious side effects occur: deep/fast breathing, drowsiness, mental/mood changes, uncontrolled movements, tingling or numbness of hands/feet.
Tell your doctor immediately if any of these rare but very serious side effects occur: easy bruising/bleeding, severe headache, vision changes (including loss of vision), persistent sore throat, unusual tiredness, seizure.
This medication may rarely cause a severe intestinal condition (Clostridium difficile-associated diarrhea) due to a resistant bacteria. This condition may occur weeks to months after treatment has stopped.

Tell your doctor immediately if you develop: persistent diarrhea, abdominal or stomach pain/cramping, or blood/mucus in your stool.
Use of this medication for prolonged or repeated periods may result in oral thrush or a new vaginal yeast infection (oral or vaginal fungal infection). Contact your doctor if you notice white patches in your mouth, a change in vaginal discharge or other new symptoms.
This medication may increase serotonin and rarely cause a very serious condition called serotonin syndrome/toxicity. The risk increases if you are also taking other drugs that increase serotonin, so tell your doctor or pharmacist of all the drugs you take (see Drug Interactions section). Get medical help right away if you develop some of the following symptoms: fast heartbeat, hallucinations, loss of coordination, severe dizziness, severe nausea/vomiting/diarrhea, twitching muscles, unexplained fever, unusual agitation/restlessness.
A very serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction may include: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

Avoid taking other MAO inhibitors (isocarboxazid, methylene blue, moclobemide, phenelzine, procarbazine, rasagiline, selegiline, tranylcypromine) during treatment with this medication. Most MAO inhibitors should also not be taken for two weeks before and after treatment with this medication. Ask your doctor when to start or stop taking this medication.
If you are currently using any of these medications listed above, tell your doctor or pharmacist before starting linezolid.
The risk of serotonin syndrome/toxicity increases if you are also taking other drugs that increase serotonin. Examples include street drugs such as MDMA/"ecstasy," St. John's wort, certain antidepressants (including mirtazapine, trazodone, SSRIs such as fluoxetine/paroxetine, SNRIs such as duloxetine/venlafaxine), tramadol, "triptans" used to treat migraine headaches (such as eletriptan, sumatriptan), tryptophan, among others.
