Warnings and precautions

Consult your doctor or pharmacist before starting to take carvedilol.

Tell your doctor if you have any of the following diseases:

• If you have any lung disease.
• If you are diabetic.
• If you have a heart condition.
• If you are taking other heart medications, especially if you are taking any of the following medications, you should inform your doctor: digitalis (increases the strength of the heartbeat), diuretics (increases urine production), ACE inhibitors (antihypertensive medication), calcium antagonists (antihypertensive medication), and antiarrhythmics (act on the heart rhythm).
• If you have any thyroid problems.
• If you are allergic and are receiving treatment for your allergy.

As with all beta-blocking medications, treatment with carvedilol should not be stopped abruptly. The dose should be gradually reduced according to your doctor's instructions.

Use in athletes:

This medicine contains carvedilol, which may produce a positive result in doping tests.

Children and adolescents

Carvedilol is not recommended for use in children and adolescents under 18 years of age due to insufficient safety and efficacy data.

Other medicines and Carvedilol TecniGen

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

This is very important because taking several medicines at the same time can increase or decrease their effect. Therefore, you should not take carvedilol with any other medicine unless your doctor has allowed it.

Note that these instructions may also apply to medicines that have been used before or may be used after.

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

• Fluoxetine and paroxetine (medicines for depression).
• Cyclosporine and tacrolimus (medicines used to prevent rejection in transplants).
• Digoxin, verapamil, diltiazem, and antiarrhythmic medications (medicines used to treat heart problems and high blood pressure).
• Amiodarone (medicine used to treat certain heart problems).
• Certain pain relievers such as aspirin and ibuprofen (NSAIDs).
• Other blood pressure medications, barbiturates, phenothiazines, tricyclic antidepressants, vasodilators, and alcohol.
• Medicines for diabetes (including insulin and oral antidiabetics).
• Clonidine (medicine used to control blood pressure or migraine).
• Rifampicin (medicine used to treat infections).
• Cimetidine (medicine used to treat stomach problems).
• Inducers or inhibitors of hepatic metabolism (medicines that modify the elimination of other medicines from the body).
• Monoamine oxidase inhibitors (medicines for depression).
• Beta-agonist bronchodilators (medicines used to improve respiratory capacity, such as in asthma).
• Adrenaline/epinefrine (used to treat severe allergic reactions).

Taking Carvedilol TecniGen with food, drinks, and alcohol

Avoid taking carvedilol simultaneously or immediately after taking grapefruit or grapefruit juice. Grapefruit or grapefruit juice may cause an increase in the active ingredient carvedilol in the blood and cause unpredictable side effects. Excessive and simultaneous or occasional consumption of alcohol should also be avoided because alcohol influences the effect of carvedilol.

Your doctor or pharmacist will inform you about the meals with which you should take the medicine.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Carvedilol is not recommended during pregnancy and breastfeeding.

Carvedilol may cause fetal death in the womb, as well as premature births. Additionally, side effects may occur in the fetus and newborn. After birth, the newborn has a higher risk of suffering from heart and lung problems.

Carvedilol passes into breast milk, so its use is not recommended during breastfeeding.

Driving and using machines

Occasionally, carvedilol may impair your ability to drive or operate machinery. This occurs especially when starting or changing treatment and when taken with alcohol.

Carvedilol TecniGen contains lactose and sucrose

If your doctor has told you that you have an intolerance to some sugars, consult with them before taking this medicine.

Use in children and adolescents

Carvedilol is not recommended for use in children and adolescents under 18 years of age due to insufficient safety and efficacy data.

Guidelines for correct administration

Take the tablets with a sufficient amount of liquid, a glass of water.
