What Eplerenone Bluefish is and what it is used for

Eplerenone Bluefish belongs to a group of medicines called selective aldosterone antagonists. These antagonists inhibit the effect of aldosterone, a substance that the body produces to regulate blood pressure and heart function. High levels of aldosterone can cause changes in the body that lead to heart failure.

Eplerenone Bluefish is used to treat your heart failure to prevent deterioration and reduce the number of hospital stays if you have:

  1. have had a recent heart attack, in combination with other medicines used to treat your heart failure, or
  2. had persistent, mild symptoms despite the treatment you have received so far.

Eplerenone contained in Eplerenone Bluefish may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.

What you need to know before you take Eplerenone Bluefish

Do not take Eplerenone Bluefish

  • if you are allergic to eplerenone or any of the other ingredients of this medicine (listed in section 6)
  • if you have elevated levels of potassium in your blood (hyperkalemia)
  • if you are taking diuretics that reduce the body’s excess fluid (potassium-sparing diuretics )
  • if you have severe kidney disease
  • if you have severe liver disease
  • if you are taking medicines for fungal infections ( ketoconazole or itraconazole)
  • if you take medicines to prevent viruses to treat HIV (nelfinavir or ritonavir)
  • if you are taking antibiotics to treat bacterial infections (clarithromycin or telithromycin)
  • if you are taking nefazodone to treat depression
  • if you are taking medicines to treat certain heart conditions or high blood pressure (so-called angiotensin-converting enzyme (ACE) inhibitors and an angiotensin receptor blocker (ARB)) together

Warnings and cautions

Talk to your doctor, pharmacist, or nurse before taking Eplerenone Bluefish:

  • if you have impaired kidney or liver function (see also “Do not take Eplerenone Bluefish”)
  • if you are taking lithium (commonly used for manic depressive illness, also called bipolar disorder)
  • if you are taking tacrolimus or ciclosporin (to treat skin conditions such as psoriasis or eczema and to prevent organ rejection after organ transplantation)

Children and young people

The safety and efficacy of eplerenone in children and adolescents have not been established.

Other medicines and Eplerenone Bluefish

Tell your doctor or pharmacist if you are taking, have recently taken o,r might take any other medicines.

  • itraconazole or ketoconazole (for the treatment of fungal infections), ritonavir, nelfinavir (medicines to prevent infections against HIV – infection ), clarithromycin, telithromycin (drugs for bacterial infections), or nefazadone (depression) when these drugs may reduce degradation of Eplerenone Bluefish and thus extend its effect in the body.
  • potassium-sparing diuretics (medicines that help to reduce the body’s excess fluid) and potassium supplements (salt tablets) as these medicines increase the risk of elevated levels of potassium in the blood.
  • angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) together (which are used to treat high blood pressure, heart disease, or certain kidney conditions) as these medicines may increase the risk of high levels of potassium in your blood.
  • lithium (commonly used to treat manic-depressive illness, also known as bipolar disorder). The use of lithium in combination with diuretics and ACE inhibitors(used to treat high blood pressure and heart disease) has been shown to cause high levels of lithium in the blood, which can cause side effects: loss of appetite; visual disturbances; fatigue; muscle weakness; muscle twitching.
  • ciclosporin or tacrolimus (to treat skin conditions such as psoriasis or eczema, and to prevent organ rejection after organ transplantation). These drugs can cause problems with the kidneys and thus increase the risk of elevated levels of potassium in the blood.
  • non-steroidal anti-inflammatory drugs (so-called NSAIDs – painkillers such as ibuprofen, for the treatment of pain, stiffness, and inflammation ). These drugs can lead to kidney problems and thus increase the risk of elevated levels of potassium in the blood.
  • Trimethoprim (a medicine used to treat bacterial infections) may increase the risk of high levels of potassium in the blood.
  • Alpha 1 receptor blockers, such as prazosin or alfuzosin (used to treat high blood pressure and certain prostate conditions) can cause a drop in blood pressure and dizziness when standing up.
  • tricyclic antidepressants such as amitriptyline or amoxapine (for the treatment of depression), antipsychotics (also called neuroleptics ) such as chlorpromazine or haloperidol (for the treatment of mental illness), amifostine (used during cancer treatment), and baclofen (for the treatment of muscle spasms). These medicines can cause a drop in blood pressure and dizziness when standing up.
  • Glucocorticoids, such as hydrocortisone or prednisone (used to treat inflammation and certain skin conditions) and tetracosactide (used mainly to diagnose and treat adrenal cortex disorders ) may reduce the blood pressure-lowering effect of Eplerenone Bluefish.
  • digoxin (for heart disease). The levels of digoxin in the blood can increase when taken together with Eplerenone Bluefish.
  • warfarin (medicine for blood clots): Caution is warranted with warfarin treatment as high levels of warfarin in the blood may cause changes in the effect of Eplerenone Bluefish in the body.
  • erythromycin (for bacterial infections), saquinavir (medicines to prevent infection against HIV ), fluconazole (antifungal), amiodarone, diltiazem, and verapamil (for cardiac problems, high blood pressure ) decreases degradation of Eplerenone Bluefish, thus prolonging Eplerenone Bluefish effect in the body.
  • St. John’s wort (herbal medicine), rifampicin (for bacterial infections), carbamazepine, phenytoin, and phenobarbital (medicines for epilepsy, among others ) can increase the breakdown of Eplerenone Bluefish and thus reduce its effect.
