NAPRILENE belongs to a group of medicines called angiotensin-converting enzyme (ACE) inhibitors.

NAPRILENE is indicated for:

- Treating high blood pressure (high blood pressure).

- Treating symptomatic heart failure.

- Preventing symptomatic heart failure.

Do not take NAPRILENE

• If you are allergic to enalapril or any of the other components of this medication (including those listed in section 6).
• If you have been previously treated with a medication from the same group of drugs as NAPRILENE (angiotensin-converting enzyme 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 (the development of large hives on the surface of the skin, especially around the eyes and lips, which can also affect hands, feet, and throat, and can cause swelling of the face, lips, tongue, and/or throat with difficulty swallowing or breathing).
• If you have diabetes or kidney insufficiency and are being treated with a medication to lower blood pressure that contains aliskirén.
• If you are more than 3 months pregnant. It is also best to avoid Naprilene at the beginning of pregnancy – see Pregnancy section.

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting to take Naprilene.

• 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 (medications that increase the elimination of urine).
• If you are following a low-sodium diet, taking potassium supplements, medications that conserve potassium, or potassium-containing salt substitutes, or if you have recently had excessive vomiting or diarrhea.
• If during treatment, an allergic reaction occurs with swelling of the face, lips, tongue, and/or throat with difficulty swallowing or breathing.
• If you are about to undergo a treatment called LDL apheresis, or a 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 dizziness or lightheadedness, especially in the initial doses and when standing up. In these cases, lying down may help).
• If you are taking any of the following medications used to treat high blood pressure (hypertension):
• • An angiotensin II receptor antagonist (ARA II) (also known as “sartanes” – for example, valsartán, telmisartán, irbesartán), particularly if you have kidney problems related to diabetes
  • Aliskirén
• If you are using any of the following medications, the risk of angioedema (rapid swelling under the skin in areas such as the throat) increases:
• • Sirolimus, everolimus, and other medications from the class of mTOR inhibitors (used to prevent organ transplant rejection).

Your doctor may monitor your renal function, blood pressure, and electrolyte levels in the blood (such as potassium) at regular intervals.

See also the information under the heading “Do not take NAPRILENE”.

You should inform your doctor if you think you may be pregnant (or could be). Naprilene is not recommended at the beginning of pregnancy and should not be taken if you are more than 3 months pregnant, as it may cause severe damage to your baby if used at that stage (see Pregnancy section).

In all these cases, inform your doctor as you may need a dose adjustment or discontinue the 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 medications and NAPRILENE

Inform your doctor or pharmacist if you are using, have used recently, or may need to use any other medication.

Certain medications may interact with NAPRILENE; in these cases, your doctor may need to adjust your dose and/or take other precautions, or discontinue some of them.

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

• If you are taking an angiotensin II receptor antagonist (ARA II) or aliskirén (See also the information under the headings “Do not take NAPRILENE” and “Warnings and precautions”)
• Antihypertensive medications (reduce elevated blood pressure).
• Diuretics (medications that increase the elimination of urine).
• Lithium (medications used to treat certain types of depression).
• Tricyclic antidepressants.
• Antipsychotics.
• Anesthetics.
• Antidiabetic medications.
• Nonsteroidal anti-inflammatory drugs (NSAIDs) (medications for pain or certain inflammation, e.g., acetylsalicylic acid).
• Sympathomimetics.

This applies especially if you are also taking:

• Medications used more frequently to prevent organ transplant rejection (sirolimus, everolimus, and other mTOR inhibitors). See section “Warnings and precautions”.
• Potassium supplements or potassium-containing salt substitutes, diuretics (especially those called potassium-sparing diuretics), other medications that may increase potassium levels in the body (such as heparin and cotrimoxazol, also known as trimethoprim/sulfamethoxazole).

Taking NAPRILENE with food, drinks, and alcohol

Foods do not affect the absorption of NAPRILENE.

Alcohol potentiates the hypotensive effect (reduction of blood pressure) of enalapril, so inform your doctor if you are taking beverages containing alcohol while taking this medication.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, or think you may be pregnant, consult your doctor or pharmacist before using this medication.

Pregnancy

You should inform your doctor if you think you may be pregnant or could 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 medication instead of Naprilene. Naprilene is not recommended at the beginning of pregnancy and should not be taken if you are more than 3 months pregnant, as it may cause severe damage to your baby if used at that stage.

Breastfeeding

Inform your doctor if you are breastfeeding or are about to start breastfeeding. While taking Naprilene, it is not recommended to breastfeed newborns (first weeks after birth), and especially 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 medication.

Driving and operating machinery

Individual responses to medication can vary.

Since NAPRILENE may cause dizziness or fatigue, be careful not to perform tasks that require special attention (driving vehicles or operating machinery) until you know how you tolerate the medication.

Naprilene 5 mg tablets contain lactose and sodium

This medication contains lactose. If your doctor has told you that you have an intolerance to certain sugars, consult with them before taking this medication.

This medication contains less than 23 mg of sodium (1 mmol) per tablet; it is essentially “sodium-free”.

Follow exactly the medication administration instructions contained in this leaflet or those indicated by your doctor. If in doubt, ask your doctor or pharmacist.

NAPRILENE tablets are administered orally.

Remember to take your medication.

Your doctor will inform you of the duration of your treatment with NAPRILENE. Do not discontinue treatment prematurely.

NAPRILENE can be taken with meals or between them along with a glass of water.

Your doctor will decide on the appropriate dose of NAPRILENE for you, depending on your condition and if you are taking other medications.

Hypertension: For most patients, the recommended initial dose is usually 5 to 20 mg once a day. Some patients may require 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 for 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 an overdose, the most likely symptom is a sensation of dizziness or vertigo due to a sudden or excessive drop in blood pressure.

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

If you forgot to take NAPRILENE

You should continue taking NAPRILENE as prescribed. Do not take a double dose to compensate for the missed doses.

Like all medications, this medication may cause side effects, although not everyone will experience them.

If you experience any of the following symptoms, stop taking this medication and talk to your doctor immediately:

• swelling of the face, lips, tongue, or throat that may cause difficulty swallowing or breathing
• swelling of your hands, feet, or ankles
• if you develop a red rash on your skin with swelling (hives).

You should be aware that patients of black race have a higher risk of suffering from this type of reaction. If you experience any of the above reactions, stop taking this medication and talk to your doctor immediately.

When you start taking this medication, you may feel a loss of consciousness or feel dizzy. If this happens, lying down may help. This is due to a decrease in your blood pressure. This will improve as you continue to take the medication. If you are concerned, please talk to your doctor.
