Linezolid
About Linezolid
Linezolid is a prescription antibiotic used to treat serious bacterial infections, including certain severe types of pneumonia and complicated skin infections. It is typically reserved for infections that are suspected or proven to be caused by drug-resistant bacteria, helping to stop the spread of these difficult-to-treat organisms inside your body.
To clear the infection completely and prevent the bacteria from returning, you must take Linezolid consistently at the exact intervals prescribed by your physician. You can take this oral medication with or without food. However, while you are using this medicine, making specific temporary dietary adjustments is necessary to avoid potential complications, such as avoiding foods that are aged, fermented, or cured.
While taking Linezolid, you may experience mild and temporary side effects such as nausea, headaches, or diarrhoea. However, you should consult your doctor immediately if you experience severe watery diarrhoea, unusual bleeding or bruising, or sudden vision changes. Your healthcare provider will monitor your blood counts if you need to take this medication for an extended period.
Before starting your treatment, talk to your doctor if you have a history of high blood pressure, thyroid disorders, kidney disease, or bone marrow suppression. Do not take this medicine if you have taken a monoamine oxidase inhibitor (MAOI) antidepressant within the last 14 days, as this combination can lead to dangerous medical complications.
This medicine can interact with several common over-the-counter and prescription drugs, including cold remedies and specific antidepressants, which may lead to a life-threatening rise in blood pressure or a condition called serotonin syndrome. It is also important to consult your doctor before starting Linezolid if you are pregnant, planning to become pregnant, breastfeeding, or if you are managing health conditions as an older adult.

Patients Concern
Disease/Condition Glossary
Bacterial infections: A bacterial infection is a condition in which harmful bacteria enter, multiply, and infect the body. Infectious or harmful bacteria can make you sick and reproduce quickly in the body. These harmful bacteria produce chemicals known as toxins, which can damage tissue and make you sick. Symptoms include fever, chills, and fatigue. Anyone can become infected with a bacterial infection. However, people with a weakened immune system or those taking immunosuppressive medications are more prone to bacterial infections.
FAQs
Linezolid is an antibiotic medication used to treat bacterial infections of the skin and lungs (pneumonia). It is also used to treat infections that are resistant to other antibiotics, such as vancomycin-resistant enterococcal infections.
Linezolid contains Linezolid (an antibiotic), which works by stopping the bacteria from making proteins necessary for their growth and multiplication, ultimately killing the bacteria. Thus, it helps treat the bacterial infection.
Diarrhoea might be a side effect of Linezolid. Drink lots of fluids and eat non-spicy food if you experience diarrhoea. If you find blood in stools (tarry stools) or if you have prolonged diarrhoea with abdominal pain, stop taking Linezolid and consult your doctor. Do not take anti-diarrheal medicine on your own.
It is recommended to complete the course of Linezolid even if you feel better, as it is an antibiotic, and leaving it in between may lead to even more severe infection. To treat your condition effectively, continue taking Linezolid for as long as your doctor has prescribed it.
Linezolid may cause thrush or candidiasis, which is a fungal infection occurring due to the overgrowth of yeast-like fungus in the mouth or throat. Regularly rinse your mouth with water to prevent the growth of fungus.
Do not take Linezolid on your own, as self-medication may lead to antibiotic resistance, in which antibiotics fail to act against specific bacterial infections.
Linezolid may affect certain laboratory test results, such as blood tests, blood sugar tests, and liver and kidney function tests. Inform the person doing the tests that you are taking Linezolid.
Linezolid may cause anaemia due to a decrease in the number of red blood cells. This could also cause unexplained bleeding or bruising. Consult your doctor if you experience unexplained bleeding or bruising.
Consult your doctor before taking Linezolid if you have hypertension (high blood pressure), as it may cause an increase in blood pressure.
You should avoid taking large quantities of food that contains high tyramine. Foods that are fermented, cured, aged or spoiled contain a high amount of tyramine, e.g. cheese, red wine, pickles, overripe fruits, etc. Consuming tyramine while taking Linezolid can result in an elevation of blood pressure, which may result in an emergency.
You should take it twice a day, every 12 hours, for example, at 8 a.m. and 8 p.m. You can take it before, with, or after food. Your doctor or clinician will determine the duration of the treatment course.
Linezolid is indicated for the treatment of gram-positive infections and is approved for treating skin and skin structure infections, bacterial pneumonia, and vancomycin-resistant enterococcal (VRE) infections, including those complicated by bacteremia.
It is usually taken with or without food or as directed by the doctor.
Common side effects of Linezolid may include thrush (fungal infection), headache, metallic taste, diarrhoea, nausea, vomiting, dizziness, constipation, and indigestion. Most of these side effects do not require medical attention and will resolve gradually over time. However, you are advised to talk to your doctor if you experience these side effects persistently.
Please consult your doctor. Linezolid should be used during pregnancy or breastfeeding only if needed, and the benefit outweighs the risk to the fetus.
Take the missed dose as soon as you remember, unless it is almost time for your next dose. In this case, skip the missed dose and take your next dose at the regular time. Never take a double dose to make up for a missed one.
It is highly recommended to avoid alcohol, especially red wine and tap beers, while taking Linezolid. These beverages contain high levels of tyramine, which can interact with the medication and cause a dangerous rise in blood pressure. Talk to your doctor or pharmacist for more information.
Linezolid begins working to stop the growth of bacteria within a few hours of your first dose. However, it may take a few days before you notice a significant improvement in your physical symptoms. Talk to your doctor if your symptoms do not improve after several days.
In rare cases, especially when taken for longer than 28 days, Linezolid can cause optic nerve damage, which may affect your vision. If you notice any blurred vision, changes in colour perception, or difficulty seeing, contact your doctor immediately.
