How to take, the dosage

Ingestion, regardless of meals.
Strictly follow the doctor’s instructions. You should not stop the treatment with Carvedilol or change its dosage without prior consultation with a physician. If it is necessary to stop the drug, the dose should be reduced gradually over a period of 1 to 2 weeks.
If there is no therapeutic effect from the treatment or a worsening of the condition is noted, consult your doctor.

Arterial hypertension.
The dose is adjusted individually. For the first 7-14 days, the recommended dose of Carvedilol is 12.5 mg (1 12.5 mg tablet) taken in the morning after breakfast. The dose may be divided into two doses of 6, 25 mg of Carvedilol (1/2 tablet of 12.5 mg). Further treatment should be carried out with Carvedilol in a dose of 25 mg (1 tablet of 25 mg) in the morning or divided into two doses of 12.5 mg of the drug (1 tablet of 12.5 mg). If necessary, after 14 days, the doctor may increase the dose again.
Take the drug after meals with a small amount of fluid.

Stable angina pectoris. The initial dose of Carvedilol is 12.5 mg (1 tablet of 12.5 mg) twice a day. After 7-14 days, under medical control, the dose of Carvedilol can be increased to 25 mg (1 tablet of 25 mg) twice a day. After 14 days, in case of insufficient effectiveness and good tolerability, the dose of Carvedilol can be further increased.

The total daily dose of Carvedilol for angina should not exceed 50 mg of the drug (2 tablets of 25 mg) administered twice a day. If your age exceeds 70 years, the daily dose of Carvedilol should not exceed 25 mg (1 tablet of 25 mg) twice a day.
If you have missed your next dose, you should take the drug as soon as possible.
However, if it is nearing your next dose, you should take only it, without doubling it.
You should take the drug regularly. If you have not taken the drug for more than 2 weeks, you should resume treatment with the lowest dose.

Chronic heart failure. The dose is adjusted individually, under the close supervision of a physician. The recommended starting dose is 3.125 mg 2 times a day for 2 weeks. If tolerated well, the dose is increased at intervals of at least 2 weeks to 6.25 mg 2 times a day, then to l2.5 mg 2 times a day, then to 25 mg 2 times a day. The dose should be increased to the maximum that is well tolerated by the patient. In patients with body weight less than 85 kg the target dose is 50 mg per day; in patients with body weight over 85 kg the target dose is 75-100 mg per day.

If treatment is interrupted for more than 2 weeks, treatment is restarted with a dose of 3.125 mg twice daily, with subsequent dose increases.

Interaction

Carvedilol may potentiate the effect of other simultaneously taken antihypertensive agents or drugs that have a hypotensive effect (nitrates).

In concomitant use of Carvedilol and diltiazem, cardiac conduction abnormalities and hemodynamic disorders may develop.
Concomitant administration of carvedilol and digoxin increases the concentration of the latter and may increase atrioventricular conduction time.

Carvedilol may potentiate the effects of insulin and oral hypoglycemic agents, and the symptoms of hypoglycemia (especially tachycardia) may mask, so regular monitoring of blood sugar levels is recommended in diabetic patients.

Microsomal oxidation inhibitors (cimetidine) enhance and inducers (phenobarbital, rifampicin) weaken the hypotensive effect of carvedilol.

Drugs that reduce catecholamines (reserpine, monoamine oxidase inhibitors) increase the risk of arterial hypotension and marked bradycardia.

Concomitant use of cyclosporine increases the concentration of the latter (correction of the daily dose of cyclosporine is recommended).
Concomitant administration of clonidine may potentiate the antihypertensive and heart rate-lowering effects of carvedilol.

General anesthetics increase the negative inotropic and hypotensive effects of carvedilol.

Special Instructions

The therapy should be prolonged and should not be stopped abruptly, especially in patients with coronary heart disease, as this may worsen the course of the underlying disease. If necessary, reduction of the drug dose should be gradual, over a period of 1-2 weeks.

At the beginning of therapy with carvedilol or when increasing the drug dose, patients, especially elderly patients, may have an excessive decrease in blood pressure, predominantly when standing up. Correction of the drug dose is necessary. Patients with chronic heart failure may experience an increase in symptoms of heart failure and edema when adjusting the dose. In this case the dose of carvedilol should not be increased, it is recommended to prescribe high doses of diuretics until the patient’s condition stabilizes.

Continuous monitoring of electrocardiogram and blood pressure is recommended with simultaneous administration of carvedilol and slow calcium channel blockers, phenylalkylamine derivatives (verapamil) and benzodiazepine (diltiazem), and with class I antiarrhythmic agents.

It is recommended to monitor renal function in patients with chronic renal failure, arterial hypotension and chronic heart failure.

If surgery is performed using general anesthesia, the anesthesiologist should be advised of prior therapy with Carvedilol.

Carvedilol has no effect on blood glucose concentration and does not cause changes in glucose tolerance test in patients with insulin-independent diabetes mellitus.

At the time of treatment, avoid the use of ethanol.

Patients with pheochromocytoma should be prescribed alpha-adrenoblockers before therapy.
Patients who wear contact lenses should be aware that the drug may cause decreased tear production.

It is not recommended to drive at the beginning of therapy and when increasing the dose of carvedilol. Other activities requiring high concentration and rapid psychomotor reactions should be refrained from.

Contraindications

With caution
Bronchospastic syndrome, chronic bronchitis, pulmonary emphysema, Prinz-metal angina, thyrotoxicosis, peripheral vascular occlusive disease, pheochromocytoma, psoriasis, renal failure, 1st degree atrioventricular block, extensive surgery and general anesthesia, diabetes, hypoglycemia, depression, myasthenia.

The presence of beta-adrenoblocking properties of the drug does not exclude the possibility of manifestation of latent diabetes mellitus, decompensation of existing diabetes mellitus or suppression of the counterinsulatory system.

Overdose

Symptoms:

Lower blood pressure (accompanied by dizziness or fainting), bradycardia. Dyspnea due to bronchospasm and vomiting may occur. In severe cases, cardiogenic shock, respiratory distress, confusion, and conduction disorders are possible.

Treatment:

Monitoring and correction of vital signs is necessary, if necessary – in the intensive care unit. Treatment is symptomatic. Intravenous use of m-cholinoblockers (atropine), adrenomimetics (epinephrine, norepinephrine) is advisable.
