• if you are allergic to tedizolid phosphate or any of the other ingredients of this medicine (listed in section 6).

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.

Diarrhoea

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:
