Uniket Retard belongs to a group of medications called organic nitrates, which relax the muscle tissue of blood vessels, widening arteries and veins. This allows for an improvement in blood circulation, reducing the workload of the heart and its oxygen needs.

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

Do not take Uniket Retard

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

?If you have very low blood pressure (systolic blood pressure less than 90 mmHg).

?In case of acute circulatory failure (shock, collapse).

?If you have severe anemia.

?In case of severe hypovolemia (decrease in total blood volume).

?In case of cardiogenic shock (circulatory collapse of cardiac origin), unless a final diastolic pressure is maintained with appropriate measures.

?If you have constrictive pericarditis (inflammation of the pericardium that compresses the heart).

?In case of cardiac tamponade (acute compression of the heart).

?If you have hypertrophic obstructive cardiomyopathy (abnormal thickening of the heart muscle).

?If you are taking medications that contain sildenafil, tadalafil, or vardenafil (medication used to treat erectile dysfunction), as the action of Uniket Retard on the heart may be altered.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Uniket Retard

?This medication is not indicated for sudden (acute) attacks of angina pectoris. In these cases, your doctor may prescribe another medication.

?If you have a decrease in filling pressure, for example, acute myocardial infarction, left ventricular failure. Avoid reducing systolic pressure below 90 mmHg.

?If you have aortic and/or mitral stenosis (narrowing of the heart valves).

?If you have orthostatic hypotension (decrease in blood pressure when standing up).

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

?Tolerance and cross-tolerance (loss of efficacy due to prolonged treatment) have been described with other medications that have isosorbide mononitrate as their active ingredient.

?It is essential that prolonged treatments with Uniket Retard are not interrupted abruptly, but gradually. Your doctor will indicate how to do this (see also “Instructions for the correct administration of the preparation”).

?It is essential that the administration of this medication be done while seated, especially at the beginning of treatment or if you are over 65 years old.

?If you have delayed gastrointestinal transit and are taking Uniket Retard, the action of the medication may be delayed.

Children and adolescents

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

Other medications and Uniket Retard

Inform your doctor or pharmacist if you are using, or have used recently, or may need to use any other medication, including those purchased without a prescription, homeopathic, herbal, and other health-related products, as it may be necessary to interrupt treatment or adjust the dose of one of them.

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

?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 diseases).

?Sildenafil, tadalafil, vardenafil (used in erectile dysfunction).

Interference with diagnostic tests

If you are to undergo any diagnostic test (blood, urine, or other analysis), inform your doctor that you are being treated with Uniket Retard, as it may alter the results.

Taking Uniket Retard with food, drinks, and alcohol

Uniket Retard tablets are administered orally, and should be swallowed whole and not chewed, with the help of a glass of water. The tablet can be taken either on an empty stomach or with food (see also “How to take Uniket Retard”).

During treatment with this medication, alcohol should not be consumed, as it may cause a decrease in blood pressure.

Pregnancy, lactation, and fertility

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

Consult your doctor or pharmacist before using any medication.

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

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

Driving and operating machinery

Observe your response to the medication, as in some cases, your ability to drive vehicles or operate machinery may be reduced due to a decrease in your reflexes, which may be exacerbated if you consume alcohol at the same time. Therefore, do not drive or operate potentially hazardous machinery until you have checked how you tolerate the medication.

Uniket Retard contains lactose

This medication contains lactose. If your doctor has indicated that you have a lactose intolerance, consult with him before taking this medication.

Follow exactly the administration instructions for Uniket Retard indicated by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist again.

Uniket Retard is not indicated as a starting treatment for the treatment and prevention of angina pectoris. Your doctor will have previously prescribed another medication with a lower dose of isosorbide mononitrate (active ingredient of Uniket Retard), such as Uniket 20 mg. Consult your doctor or pharmacist if you have any doubts.

The usual dose is 1 tablet once a day, in the morning. However, if the angina crisis occurs mainly at night, it can be taken at night, before going to bed.

Instructions for the 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 medication.

Your doctor will indicate the duration of your treatment with Uniket Retard and will also be able to adjust your dose if necessary. Do not change the dose indicated by your doctor and do not suspend treatment without consulting them first, as it may be harmful to your health.

It is essential to start and end treatment with Uniket Retard gradually and never abruptly. Your doctor will indicate the way to increase or decrease the dose gradually.

If you estimate that the action of Uniket Retard is too strong or too weak, inform your doctor or pharmacist.

If you take more Uniket Retard than you should

If for any reason you took more Uniket Retard tablets than you should have, the following symptoms may appear: rapid decrease 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 reutilize the protein (hemoglobin) used for oxygen transport) and cyanosis (blue discoloration of the skin and mucous membranes) have been described, with subsequent appearance of rapid breathing, anxiety, loss of consciousness, and cardiac arrest. It cannot be ruled out that an overdose of Uniket Retard may cause this adverse reaction.

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

The procedure to follow in case of a possible overdose of Uniket Retard is as follows:

?General measures

- Stop administering the medication.

- In case of significant decrease in blood pressure:

- place the patient lying down, with legs elevated and head inclined downward,

- if necessary, administration of intravenous fluids and oxygen,

- if shock appears, admission to an intensive care unit.

?Special measures

- Increase blood pressure if it is very low.

- Treatment with medications that increase blood pressure (vasopressors), (only in patients who do not respond to fluid administration).

- Treatment of methemoglobinemia:

- vitamin C, methylene blue, or toluidine blue,

- oxygen (if necessary)

- assisted respiration,

- hemodialysis (if necessary).

?Resuscitation measures

- In case of signs of cardiac arrest, initiate resuscitation measures immediately.

In case of overdose or accidental ingestion, you can also call the Toxicological Information Service, Telephone 915 62 04 20, indicating the name of the medication and the amount taken.

If you forget to take Uniket Retard

In case of forgotten dose, take the medication as soon as possible, continuing treatment as prescribed. However, if the next dose is near, it is better not to take the forgotten dose and wait for the next one. Do not take a double dose to compensate for the forgotten doses.

If you interrupt treatment with Uniket Retard

If you interrupt treatment with Uniket Retard abruptly, a sudden increase in blood pressure may occur. Therefore, it is recommended that prolonged treatments not be interrupted abruptly, but gradually, following the instructions received from your doctor.

If you have any other doubts about the use of this product, ask your doctor or pharmacist.
