1. What Sivextro is and what it is used for

Sivextro is an antibiotic that contains the active substance tedizolid phosphate. It belongs to a group of medicines called “oxazolidinones”.

It is used to treat adults and adolescents 12 years of age and older with infections of the skin and tissues below the skin.

It works by stopping the growth of certain bacteria which can cause serious infections.

2. What you need to know before you take Sivextro
Do not take Sivextro
  • if you are allergic to tedizolid phosphate or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Your doctor will have decided if Sivextro is suitable to treat your infection.

Talk to your doctor or nurse before taking Sivextro if any of the following apply to you:

  • are suffering from diarrhoea, or have suffered from diarrhoea whilst (or up to 2 months after) taking antibiotics in the past.
  • are allergic to other medicines belonging to the group “oxazolidinones” (e.g., linezolid, cycloserine).
  • have a history of bleeding or easy bruising (which may be a sign of low numbers of platelets, the small cells involved in clotting in your blood).
  • have kidney problems.
  • are taking certain medicines to treat depression, known as tricyclics, SSRIs (selective serotonin reuptake inhibitors), opioids or MAOIs (monoamine oxidase inhibitors). The use of these medicines together with tedizolid phosphate can lead to serotonin syndrome, a potentially life-threatening condition (with symptoms such as feeling disorientated, difficulty concentrating, high temperature, increased reflexes, difficulty to coordinate muscle movements). See Other medicines and Sivextro for examples.
  • are taking certain medicines to treat migraine known as “triptans”. See Other medicines and Sivextro for examples.

Ask your doctor or pharmacist if you are not sure whether you are taking any of these medicines.


Contact your doctor straight away if you suffer from diarrhoea during or after your treatment. Do not take any medicine to treat your diarrhoea without first checking with your doctor.

Resistance to antibiotics

Bacteria can become resistant to treatment with antibiotics over time. This is when antibiotics cannot stop the growth of bacteria and treat your infection. Your doctor will decide if you should be given Sivextro to treat your infection.

Possible side effects

Certain side effects have been observed with Sivextro or another member of the oxazolidinone class when administered over a duration exceeding that recommended for Sivextro. Tell your doctor straight away if you suffer from any of the following while taking Sivextro:

  • a low white blood cell count
  • anaemia (low red blood cells)
  • bleeding or bruising easily
  • loss of sensitivity in your hands or feet (such as numbness, prickling/tingling, or sharp pains)
  • any problems with your eyesight such as blurred vision, changes in colour vision, difficulty in seeing detail or if your field of vision becomes restricted.


This medicine should not be used in children under 12 years of age as it has not been studied enough in this population.

Other medicines and Sivextro

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. It is especially important that you tell your doctor if you are also taking:

  • amitriptyline, citalopram, clomipramine, dosulepin, doxepin, fluoxetine, fluvoxamine, imipramine, isocarboxazid, lofepramine, moclobemide, paroxetine, phenelzine, selegiline, sertraline, duloxetine and venlafaxine (used to treat depression). There is a risk that tedizolid phosphate could interact with certain medicines, including those mentioned, to cause side effects such as changes in blood pressure or temperature.
  • sumatriptan, zolmitriptan (used to treat migraine)
  • opioids (such as fentanyl)
  • imatinib, lapatinib (used to treat cancer)
  • methotrexate (used to treat cancer, rheumatoid arthritis or psoriasis)
