  • If you have been treated with a medicine of the same group as NAPRILENE (ACE inhibitors) and have had allergic reactions with swelling of the face, lips, tongue and/or throat with difficulty swallowing or breathing.
  • If you have been diagnosed with hereditary or unknown cause angioedema (development of large hives on the skin surface, especially around the eyes and lips, which can also affect hands, feet, and throat and can also cause swelling of the face, lips, tongue and/or throat with difficulty swallowing or breathing).
  • If you have diabetes or kidney problems and are being treated with a blood pressure-lowering medicine that contains aliskiren.
  • If you are more than 3 months pregnant. It is also better to avoid NAPRILENE at the start of pregnancy – see section Pregnancy.

  • If you have heart disease.
  • If you have blood disorders.
  • If you have diabetes.
  • If you have liver problems.
  • If you have kidney problems (including kidney transplant).
  • If you are undergoing dialysis.
  • If you are receiving treatment with diuretics (medicines that increase urine production).

  • If an allergic reaction with swelling of the face, lips, tongue and/or throat with difficulty swallowing or breathing occurs during treatment.
  • If you are about to undergo a treatment called LDL apheresis or desensitization treatment to reduce the effect of an allergy to bee or wasp stings.
  • If you have low blood pressure (you may notice it as fainting or dizziness, especially in the initial doses and when standing up. In these cases, lying down may help).
  • If you are taking any of the following medicines used to treat high blood pressure (hypertension):
    • an angiotensin II receptor antagonist (ARA II) (also known as "sartans" – e.g., valsartan, telmisartan, irbesartan), especially if you have kidney problems related to diabetes
    • aliskiren
  • If you are taking any of the following medicines, the risk of angioedema (rapid swelling under the skin in areas such as the throat) increases:
    • Sirolimus, everolimus, and other mTOR inhibitor medicines (used to prevent organ transplant rejection).

Your doctor may monitor your kidney function, blood pressure, and blood electrolyte levels (e.g., potassium) at regular intervals.

See also the information under the heading "Do not take NAPRILENE".

You must inform your doctor if you think you are pregnant (or might be). NAPRILENE is not recommended at the start of pregnancy and must not be taken if you are more than 3 months pregnant, as it may cause serious harm to your baby if used at this stage (see section Pregnancy).

In all these cases, inform your doctor, as you may need a dose adjustment or discontinuation of medication with NAPRILENE.

Before undergoing surgery or anesthesia (even at the dentist's office), inform your doctor or dentist that you are taking NAPRILENE, as there may be a sudden drop in blood pressure associated with anesthesia.

Other medicines and NAPRILENE

Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines.

Certain medicines may interact with NAPRILENE; in these cases, your doctor may need to modify your dose and/or take other precautions or interrupt treatment with some of them.

It is essential that you inform your doctor if you are taking or have recently taken any of the following medicines:

  • If you are taking an angiotensin II receptor antagonist (ARA II) or aliskiren (see also the information under the headings "Do not take NAPRILENE" and "Warnings and precautions").
  • Blood pressure-lowering medicines (to reduce high blood pressure)
  • Diuretics (medicines that increase urine production).
  • Lithium (medicines used to treat certain types of depression).
  • Tricyclic antidepressants.
  • Antipsychotics.
  • Anesthetics.
  • Anti-diabetic medicines.
  • Non-steroidal anti-inflammatory medicines (NSAIDs) (medicines to treat pain or certain inflammations, e.g., acetylsalicylic acid).
  • Sympathomimetics.

This applies especially if you are also taking:

  • Medicines commonly used to prevent organ transplant rejection (sirolimus, everolimus, and other mTOR inhibitor medicines). See section "Warnings and precautions".
  • Potassium supplements or salt substitutes that contain potassium, diuretics (especially potassium-sparing ones), or other medicines that may increase potassium levels in the body (such as heparin and cotrimoxazole, also known as trimethoprim/sulfamethoxazole).

Taking NAPRILENE with food, drinks, and alcohol

Food does not affect the absorption of NAPRILENE.

Alcohol enhances the blood pressure-lowering effect of enalapril, so inform your doctor if you are taking alcoholic beverages while being treated with this medicine.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.

Pregnancy

You must inform your doctor if you think you are pregnant or might be. Normally, your doctor will advise you to stop taking NAPRILENE before becoming pregnant or as soon as you know you are pregnant and advise you to take a different medicine instead of NAPRILENE. NAPRILENE is not recommended at the start of pregnancy and must not be taken if you are more than 3 months pregnant, as it may cause serious harm to your baby if used from the third month of pregnancy onwards.

Breastfeeding

Inform your doctor if you are breastfeeding or about to start breastfeeding. While taking NAPRILENE, breastfeeding is not recommended in newborns (first few weeks after birth), especially in premature babies. In the case of an older baby, your doctor should advise you on the benefits and risks of taking NAPRILENE compared to other treatments while breastfeeding.

Consult your doctor or pharmacist before using any medicine.

Driving and using machines

Individual responses to the medicine may vary.

Since NAPRILENE may cause dizziness or fatigue, avoid performing tasks that require special attention (driving vehicles or operating machinery) until you know how you tolerate the medicine.

3. How to take NAPRILENE 20 mg tablets

Follow exactly the administration instructions of the medicine contained in this leaflet or as indicated by your doctor. In case of doubt, ask your doctor or pharmacist.

NAPRILENE tablets are administered orally.

Remember to take your medicine.

Your doctor will indicate the duration of your treatment with NAPRILENE. Do not stop treatment before.

NAPRILENE can be taken with or without food, with a glass of water.

Your doctor will decide the appropriate dose of NAPRILENE that you should take, depending on your condition and whether you are taking other medicines.

Hypertension: For most patients, the recommended initial dose is usually 5 to 20 mg once a day. Some patients may need a lower initial dose.

The usual long-term dose is 20 mg once a day.

Heart failure: The recommended initial dose is usually 2.5 mg once a day. Your doctor will gradually increase the dose until the appropriate dose is reached in your case. The usual long-term dose is 20 mg per day in one or two doses.

If you take more NAPRILENE than you should

If you take more NAPRILENE than you should, consult your doctor or pharmacist immediately.

In case of overdose, the most likely symptom is a feeling of dizziness or vertigo due to a sudden or excessive drop in blood pressure.

In case of overdose or accidental ingestion, consult the Toxicology Information Service. Telephone 915 620 420.

If you forget to take NAPRILENE

You should continue taking NAPRILENE as prescribed. Do not take a double dose to make up for forgotten doses.
