Dopegyt is used to treat high blood pressure.

2. Important information before using Dopegyt

When not to use Dopegyt

• if the patient is allergic to methyldopa or any of the other ingredients of this medicine (listed in section 6),
• if the patient has active liver disease (e.g. acute hepatitis, liver cirrhosis),
• if the patient has a history of liver disease induced by methyldopa,
• if the patient is taking MAO inhibitors (e.g. moklobemide used to treat depression or selegiline used to treat Parkinson's disease or Alzheimer's disease) at the same time,
• if the patient has depression,
• if the patient has a pheochromocytoma (a special type of adrenal gland tumor).

Warnings and precautions

Before starting treatment with Dopegyt, you should discuss it with your doctor or pharmacist.

• In case of liver disease in the past, abnormal liver test results, or kidney disease, you should inform your doctor, as a dose reduction may be necessary in such cases.
• In case of a diagnosed special metabolic disorder (porphyria) in yourself or a close relative, you should inform your doctor, as the use of methyldopa requires special caution in such cases.
• During treatment, especially if doses above 1000 mg are used and primarily after 6-12 months of therapy, laboratory abnormalities (positive direct Coombs test result) may occur in 10-20% of patients. In less than 5% of such patients, hemolytic anemia (anemia caused by premature destruction of red blood cells) may develop. Therefore, before starting treatment and then every 6-12 months during treatment, blood morphology and direct Coombs test should be checked. Symptoms of anemia may include: pale skin, weakness, jaundice. If such symptoms occur, you should stop taking this medicine immediately and consult a doctor. If the cause of these symptoms is methyldopa, you should never use Dopegyt again.
• As an allergic reaction to methyldopa, liver cell damage may occur, sometimes severe. Therefore, during the first 6-12 weeks of treatment, liver function tests should be performed with the frequency recommended by the doctor, and in case of fever of unknown origin or jaundice, treatment should be stopped immediately. If the cause of liver damage is methyldopa, you should never use Dopegyt again.
• Very rarely, during treatment, hematopoietic disorders (decrease in white blood cell and platelet count) may occur. If oral ulcers, sore throat, small red spots on the body, black stools, or blood in the urine occur, you should stop taking this medicine and consult a doctor. These symptoms usually resolve on their own after discontinuation of the medicine.
• In some patients, swelling and weight gain may occur. These symptoms usually resolve after administration of diuretics. You should consult a doctor if these symptoms worsen despite diuretic treatment or if shortness of breath (difficulty breathing) or easy fatigue occurs, as it may be necessary to discontinue the medicine.
• In case of dialysis treatment, it may be necessary to administer an additional dose of the medicine after dialysis, as methyldopa is removed from the body during dialysis.
• You should inform your doctor about treatment with Dopegyt before blood transfusion, general anesthesia, and before diagnostic tests for a special type of adrenal gland tumor (pheochromocytoma).
• You should consult a doctor in case of brain vessel damage or disease and the occurrence of involuntary movements, as it may be necessary to discontinue Dopegyt.

Dopegyt and other medicines

You should tell your doctor or pharmacist about all medicines you are currently taking or have recently taken, as well as any medicines you plan to take.
Dopegyt should not be used at the same time as MAO inhibitors(e.g. moklobemide used to treat depression or selegiline used to treat Parkinson's disease or Alzheimer's disease).
Some medicines may weakenthe antihypertensive effect of Dopegyt, and their concurrent use requires special caution and careful medical supervision:

• medicines containing adrenaline, ephedrine, pseudoephedrine used to treat colds, coughs, and asthma,
• certain medicines used to treat depression (e.g. imipramine, amitriptyline),
• medicines used to treat certain mental illnesses (e.g. chlorpromazine, trifluoperazine),
• oral iron supplements (iron gluconate and iron sulfate reduce methyldopa absorption),
• medicines used to relieve fever and pain (e.g. piroxicam, diclofenac, naproxen),
• estrogens (preparations containing female sex hormones).

Concomitant use of Dopegyt and the following medicines may enhancethe antihypertensive effect of Dopegyt:

• other antihypertensive medicines,

• lithium (used to treat psychiatric disorders),
• levodopa (used to treat Parkinson's disease),
• alcohol and medicines used to treat anxiety, insomnia, or allergies,
• anticoagulant medicines (e.g. acenocoumarol); concomitant use of these medicines increases the risk of bleeding,
• bromocriptine (reduces prolactin and growth hormone release in the body, used to treat diseases where reduced levels of these substances are necessary),
• haloperidol (used to treat mental disorders).

Dopegyt with food and alcohol

During treatment, you should avoid consuming alcoholic beverages. Tablets can be taken before or after meals.

Pregnancy and breastfeeding

In pregnancy and during breastfeeding, or if you suspect you are pregnant, or if you plan to become pregnant, you should consult a doctor before using this medicine.
Although no clear teratogenic effect has been described, fetal damage cannot be ruled out.
Therefore, Dopegyt should not be used during pregnancy, unless the expected benefits outweigh the potential risk.
Methyldopa passes into breast milk, and therefore breastfeeding women should not use this medicine unless advised by a doctor after careful evaluation of benefits and risks.

The medicine contains less than 1 mmol (23 mg) of sodium per tablet, which means the medicine is considered "sodium-free".

3. How to use Dopegyt

This medicine should always be used according to the doctor's or pharmacist's recommendations. In case of doubts, you should consult a doctor or pharmacist.
Tablets can be taken before or after meals.
The recommended dose is
Adults
The recommended initial dose over the first two days is 250 mg 2-3 times a day. The doctor may gradually increase or decrease the initial dose - depending on the degree of blood pressure reduction - at intervals of not less than two days. Initially, it is recommended to increase the evening dose. The recommended maintenance dose is 500-2000 mg per day, divided into 2-4 doses. The maximum daily dose is 3 g. After 2 or 3 months of treatment, tolerance to the medicine may develop. The doctor may then decide to add a diuretic or increase the dose of methyldopa.
Elderly patients
In elderly patients, treatment should be started with the lowest possible dose, not exceeding 250 mg per day. The doctor may increase or decrease the dose, depending on the degree of blood pressure reduction, at intervals of not less than two days, up to a maximum dose of 2000 mg, which should not be exceeded.
Use in children and adolescents
In children and adolescents, the recommended initial dose is 10 mg/kg body weight per day, given in 2-4 divided doses.
If necessary, the doctor may gradually increase the daily dose at intervals of not less than two days until a satisfactory response to treatment is achieved. The maximum dose is 65 mg/kg body weight per day, up to a maximum dose of 3 g per day.
Use in patients with renal impairment
The doctor will reduce the dose according to the degree of renal impairment. In case of mild renal impairment, it is recommended to extend the interval between doses to 8 hours, in moderate renal impairment to 8-12 hours, and in severe renal impairment to 12-14 hours.
Since methyldopa is removed from the body during dialysis, a supplementary dose of 250 mg is recommended after dialysis treatment.
