Renitec comp – Enalapril maleate / Hydrochlorothiazide uses, dose and side effects


20 mg / 12.5 mg tablets
enalapril maleate / hydrochlorothiazide

What Renitec comp is and what it is used for

Renitec comp is used to treat high blood pressure.

The active substances enalapril and hydrochlorothiazide both have antihypertensive effects and complement each other. Enalapril, which is a so-called ACE inhibitor, dilates blood vessels and makes it easier for the heart to pump blood to all parts of the body. Hydrochlorothiazide, which is a diuretic, lowers blood pressure through the salt and diuretic effect.

Enalapril maleate and hydrochlorothiazide contained in Renitec comp may also be authorized 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 taking Renitec comp

Do not take Renitec comp

  • if you are allergic to enalapril maleate, hydrochlorothiazide, or any of the other ingredients of this medicine (listed in section 6)
  • if you have severe hepatic or renal impairment
  • if you have gout
  • if you have previously been treated with another preparation belonging to the same group of medicines as Renitec Comp ( ACE inhibitor ) and then had an allergic reaction in the form of swelling of the face, lips, tongue, and/or throat with difficulty swallowing or breathing ( angioedema )
  • if you have hereditary angioedema or angioedema without a known cause (idiopathic)
  • if you have diabetes or renal impairment and are being treated with a blood pressure-lowering medicine containing aliskiren
  • pregnant women should not use Renitec comp during the last 6 months of pregnancy (even earlier in pregnancy it is good to avoid Renitec comp, see Pregnancy and breast-feeding)
  • if you have taken or are currently taking sacubitril/valsartan, a medicine used to treat a type of long-term ( chronic ) heart failure in adults, as it increases the risk of angioedema (rapid swelling under the skin in an area such as the throat).

  • if you have impaired kidney function

  • if you are on a low-salt diet
  • if you are being treated with potassium supplements, potassium-sparing agents, potassium-containing salt substitutes, or other medicines that may increase the potassium level in your blood (eg heparin [a medicine used to prevent blood clots], products containing trimethoprim such as the combination trimethoprim/sulfamethoxazole [medicines used to treat infection er])
  • if you have diabetes
  • if you have previously had an allergic reaction with swelling of the face, lips, tongue, and/or throat with difficulty breathing or swallowing ( angioedema ). You should be aware that black patients are at greater risk of developing these types of reactions when treated with ACE inhibitors.
  • if you are being treated with drugs that weaken the immune system ( immunosuppressive treatment eg after organ transplantation)
  • if you have had skin cancer or if you get an unforeseen skin change during treatment. Treatment with hydrochlorothiazide, especially long-term use with high doses, may increase the risk of certain types of skin and lip cancer (non-melanoma skin cancer). Protect your skin from exposure to sunlight and UV rays while taking Renitec comp
  • if you are taking any of the following medicines, as the risk of angioedema may be increased:
    • racecadotril, a medicine used to treat diarrhea
    • drugs used to prevent rejection of transplanted organs and against cancer (eg temsirolimus, sirolimus, everolimus)
    • vildagliptin, a medicine used to treat diabetes
  • if you are taking any of the following medicines used to treat high blood pressure:
    • an angiotensin II receptor blocker (ARB) (also known as sartans – for example, valsartan, telmisartan, irbesartan), especially if you have diabetes-related kidney problems
    • aliskiren.
  • if you experience impaired vision or eye pain. This may be a symptom of fluid accumulation in the eye (between the choroid and retina) or an increase in pressure in the eye and may occur within a few hours to weeks after taking Renitec comp. This can lead to permanent visual impairment if left untreated. If you have previously had an allergy to penicillin or sulfonamide, you may be at a higher risk of developing this

Your doctor may need to check your kidney function, blood pressure, and the number of electrolytes (eg potassium ) in your blood at regular intervals.

If you have diabetes and are taking insulin or diabetes medication in tablet form, you should be careful to monitor your blood sugar levels. This is especially important during the first month of taking Renitec comp.

Serious allergic reactions may occur if Renitec comp is used in the treatment of hypersensitivity to bee or wasp venom ( hyposensitization ) or so-called LDL -apheresis. Therefore, tell your doctor that you are using Renitec comp if you are going to undergo such treatment.

Before surgery and anesthesia (also applies to the dentist), the doctor/dentist should know that you are being treated with Renitec comp, as there is a risk that your blood pressure may drop suddenly.
