When should I not take this medication?
You must not take it if you are allergic to nicardipine or its components, if you have had recent cerebral hemorrhages, if you have increased intracranial pressure (intracranial hypertension), if you are pregnant, if you are breastfeeding, if you have advanced narrowing of the heart valves (aortic stenosis), or if you are under 18 years of age.
What side effects can Flusemide cause?
It may cause effects such as palpitations, low blood pressure, swelling in the arms and legs, dizziness, headache, drowsiness, insomnia, nausea, digestive problems (constipation or diarrhea), weakness, a feeling of flushing, or frequent urge to urinate.

- Prevention of neuronal damage caused by constriction of cerebral blood vessels following hemorrhage.

Warnings and precautions
Consult your doctor or pharmacist before starting to take Flusemide.
If you experience pain within 30 minutes after starting treatment or after increasing the dose, stop taking this medicine.

- patients with heart problems,
- patients with liver and/or kidney problems,
- elderly patients,
- patients who have had a stroke (cerebral infarction or hemorrhage).
If you are scheduled to undergo any diagnostic tests (including blood or urine tests, etc.), inform your doctor that you are taking/using this medicine, as it may alter test results.

Taking Flusemide with other medicines
Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.
Some medicines may interact with this medicine, requiring a dose adjustment or discontinuation of one of the treatments.
Cimetidine (used for gastric ulcers) increases plasma levels of nicardipine.
Caution should be exercised when carbamazepine (used for epilepsy) and nicardipine are administered together.
This medicine may be used in combination with other drugs for the treatment of high blood pressure (beta-blockers, diuretics), but the possibility of an additive effect leading to postural hypotension (a drop in blood pressure when sitting up after lying down or standing up after sitting) should be considered.
Elevated levels of cyclosporine (used as an immunosuppressant) have been reported when used concomitantly with nicardipine.
Concomitant administration of nicardipine and digoxin (used to treat certain heart conditions) may increase the effects of digoxin.
Rifampicin (used to treat certain infectious diseases) may substantially reduce plasma levels of nicardipine; therefore, the combined use of rifampicin and nicardipine should be done with caution.
In particular, inform your doctor if you are taking other medicines to control the body's immune system, such as cyclosporine, tacrolimus, or sirolimus.
Taking Flusemide with food, drinks, and alcohol
Nicardipine may be taken independently of meals, except as indicated in section 3.
