1. What Uniket is and what it is used for

Uniket belongs to a group of medicines called organic nitrates, which relax the muscle in blood vessels, widening arteries and veins. This improves blood circulation, reducing the heart's workload and its oxygen requirements.

This medicine is indicated for the treatment and prevention of angina pectoris.

2. What you need to know before starting to take Uniket

Do not take Uniket

• If you are allergic to isosorbide mononitrate, to organic nitrates in general, or to any of the other components of this medicine (listed in section 6).

• If you have very low blood pressure (systolic blood pressure below 90 mmHg).

• In cases of acute circulatory failure (shock, collapse).

• If you suffer from severe anemia.

• In cases of severe hypovolemia (decreased total blood volume).

• In cases of cardiogenic shock (circulatory collapse of cardiac origin), unless diastolic filling pressure is maintained with appropriate measures.

• If you suffer from constrictive pericarditis (inflammation of the pericardium that compresses the heart).

• In cases of cardiac tamponade (acute compression of the heart).

• If you suffer from obstructive hypertrophic cardiomyopathy (abnormal thickening of the heart muscle).

• If you are concurrently taking medicines containing sildenafil, tadalafil, or vardenafil (medicines used to treat erectile dysfunction), as the effect of Uniket on the heart may be altered.

Warnings and precautions

Talk to your doctor or pharmacist before starting to take Uniket Retard.

• This medicine is not indicated for sudden (acute) angina attacks. In such cases, your doctor has likely prescribed another medicine for you.

• If you have reduced filling pressure, for example, acute myocardial infarction, left ventricular failure. Systolic blood pressure should be kept from falling below 90 mmHg.

• If you suffer from aortic and/or mitral stenosis (narrowing of the heart valves).

• If you suffer from orthostatic hypotension (decrease in blood pressure upon standing).

• If you have diseases associated with increased intracranial pressure (however, so far, an additional increase in intracranial pressure has only been observed after intravenous administration of high doses of nitroglycerin).

• Tolerance and cross-tolerance (loss of efficacy due to continuous treatment) have been reported with other medicines containing nitrates as the active ingredient.

• It is important that prolonged treatment with Uniket is not stopped abruptly, but gradually tapered off. Your doctor will advise you on how to do this (see also "Instructions for correct administration of the preparation").

• It is important that this medicine is taken while sitting down, especially at the beginning of treatment or if you are over 65 years of age.

Children and adolescents

The efficacy and safety of use in children have not been established. Therefore, the use of Uniket is not recommended in children and adolescents (under 18 years of age).

Other medicines and Uniket

Inform your doctor or pharmacist if you are currently taking, have recently taken, or might need to take any other medicines, including those obtained without a prescription, homeopathic remedies, herbal medicines, and other health-related products, as it may be necessary to interrupt treatment or adjust the dose of any of them.

It is especially important that you inform your doctor if you are taking any of the following medicines:

• Beta-blockers, calcium antagonists, diuretics, ACE inhibitors (used to treat high blood pressure).

• Vasodilators (used in heart and blood vessel diseases).

• Tricyclic antidepressants (for the treatment of depression).

• Neuroleptics (used in nervous system disorders).

• Sildenafil, tadalafil, vardenafil (used for erectile dysfunction).

Interference with diagnostic tests

If you are due to have any diagnostic tests (blood, urine, or other analyses), inform your doctor that you are being treated with Uniket, as it may alter the results.

Taking Uniket with food, drinks, and alcohol

Uniket tablets are taken orally, swallowed whole and unchewed with a glass of water. The tablet may be taken either on an empty stomach or with food (see also "3. How to take Uniket").

Alcohol should not be consumed during treatment with this medicine, as it may cause a drop in blood pressure.

Pregnancy, breastfeeding, and fertility

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

Consult your doctor or pharmacist before using any medicine.

Uniket should not be taken during the first three months of pregnancy unless, in the strict opinion of your doctor, it is absolutely necessary. Therefore, if you are pregnant or think you might be, inform your doctor as soon as possible.

Caution is advised if Uniket is administered to a breastfeeding mother. The currently available information is insufficient to determine the risk during breastfeeding.

Driving and use of machines

Be aware of how you respond to the medication, as in some cases your ability to drive or operate machinery may be impaired due to reduced reflexes, which could be worsened by alcohol consumption. Therefore, do not drive or operate potentially dangerous machinery until you know how you tolerate the medicine.

Uniket contains lactose

This medicine contains lactose. If your doctor has informed you that you have an intolerance to certain sugars, consult with him before taking this medicine.

3. How to take Uniket

Follow exactly the administration instructions for Uniket as given by your doctor or pharmacist. If in doubt, consult your doctor or pharmacist again.

The usual dose is 1 tablet two or three times daily (80 to 120 mg per day), depending on the individual needs of each patient.

The maximum recommended dose for this medicine is 120 mg (3 tablets per day). However, your doctor will indicate how you should take the medicine and how many tablets you should take each day.

Instructions for correct administration of the preparation

Swallow the tablets whole, without chewing, with a sufficient amount of liquid (for example, a glass of water). Remember to take your medicine.

Your doctor will determine the duration of your treatment with Uniket and may adjust your dose if necessary. Do not change the dose prescribed by your doctor, and do not stop treatment without first consulting your doctor, as this could be harmful to your health.

It is important that you start and stop treatment with Uniket gradually and never abruptly. Your doctor will advise you on how to gradually increase or reduce the dose.

If you feel that the effect of Uniket is too strong or too weak, inform your doctor or pharmacist.

If you take more Uniket than you should

If for any reason you take more Uniket tablets than you should, the following symptoms may occur: rapid drop in blood pressure, pallor, sweating, weak pulse, increased heart rate (tachycardia), dizziness, headache, feeling of weakness, nausea, vomiting, and diarrhea.

In patients treated with organic nitrates, cases of methemoglobinemia (a blood disorder in which the body cannot reuse the protein (hemoglobin) used for oxygen transport) and cyanosis (bluish discoloration of the skin and mucous membranes) have been reported, followed by rapid breathing, anxiety, loss of consciousness, and cardiac arrest. It cannot be ruled out that an overdose of Uniket may cause this adverse reaction.

Very high doses may cause increased intracranial pressure with cerebral symptoms.

The following measures should be taken in case of a possible Uniket overdose:

? General measures

• Discontinue administration of the medicine.
• In case of a significant drop in blood pressure:
• place the patient lying down with legs elevated and head tilted downward,
• if necessary, administer intravenous fluids and oxygen,
• if shock occurs, admission to an intensive care unit.

? Special measures

• Increase blood pressure if it is very low.
• Treatment with medications that raise blood pressure (vasopressors), (only in patients who do not respond to intravenous fluids).
• Treatment of methemoglobinemia:
• vitamin C, methylene blue, or toluidine blue,
• oxygen (if necessary),
• assisted ventilation,
• hemodialysis (if necessary).

? Resuscitation measures

• In case of signs of cardiorespiratory arrest, initiate resuscitation measures immediately.

In case of overdose or accidental ingestion, you may also call the Toxicology Information Service at telephone number 915 62 04 20, indicating the name of the medicine and the amount taken.

If you forget to take Uniket

If you miss a dose, take the medicine as soon as possible and continue treatment as prescribed. However, if it is almost time for the next dose, it is better not to take the missed dose and wait for the next scheduled dose. Do not take a double dose to make up for a missed dose.

If you stop treatment with Uniket

If you stop treatment with Uniket abruptly, a sudden increase in blood pressure may occur. Therefore, prolonged treatments should not be stopped abruptly, but gradually, following your doctor's instructions.

If you have any further questions about the use of this medicine, ask your doctor or pharmacist.
