Warnings and precautions

Talk to your doctor or pharmacist before starting Filspari if:

• you have decreased kidney function: your doctor may perform additional tests to monitor your kidney function (by determining creatinine and potassium levels in the blood).
• you experience swelling in your hands, ankles, or feet due to fluid accumulation in your body: your doctor may ask you to take an additional medicine to remove water from your body or may change the dose of Filspari.
• you have liver problems: your doctor will perform a blood test before starting your treatment and regularly during treatment to check if your liver is working properly and will stop treatment with Filspari if necessary. Signs that your liver may not be working properly: nausea (vomiting), vomiting, fever (high temperature), stomach pain (abdominal pain), jaundice (yellowing of the skin or the whites of the eyes), dark urine, itching of the skin, lethargy or fatigue (unusual tiredness), flu-like syndrome (joint and muscle pain along with fever). If you notice any of these signs, tell your doctor immediately.
