1. What is Gutron and what is it used for

Gutron raises low blood pressure by constricting small veins and arteries and preventing the accumulation of more blood in the lower limbs. Low blood pressure and blood accumulation in the lower limbs can cause dizziness and cerebral hypoperfusion. It is indicated for the treatment of severe orthostatic hypotension (a drop in blood pressure when standing up, leading to dizziness or fainting) caused by disorders of the autonomic nervous system, when there is no possibility of causal treatment.

2. Important information before taking Gutron

When not to take Gutron:

• if the patient is allergic to midodrine hydrochloride or any of the other ingredients of this medicine (listed in section 6);
• if the patient has:
• severe organic heart and circulatory system disorders, hypertension, arrhythmias;
• severe vascular diseases (e.g., cerebral artery occlusion and spasm);
• acute kidney inflammation, severe kidney failure, prostate enlargement with prolonged urine retention, mechanical obstruction of urination, urinary retention;
• proliferative diabetic retinopathy (retinal disorders in diabetes);
• phaeochromocytoma (a tumor of the adrenal gland);
• hyperthyroidism;
• glaucoma with a narrow angle of filtration;
• during pregnancy or breastfeeding.

Warnings and precautions

Before starting to take Gutron, the patient should discuss it with their doctor or pharmacist. Particular caution should be exercised when taking Gutron:

• if the patient suffers from other diseases (especially right ventricular hypertrophy due to lung disease, increased intraocular pressure, liver and kidney dysfunction);
• when taking other medicines, especially those containing vasoconstrictor substances (see section "Gutron and other medicines");
• during pregnancy and breastfeeding.

The doctor should be informed about all the above situations. The doctor may recommend additional tests to avoid side effects. During treatment, blood pressure should be regularly monitored in the lying, sitting, and standing positions. At the beginning of treatment, the doctor will assess the risk of hypertension in the lying or sitting position. Attention should be paid to symptoms indicating the occurrence of hypertension (palpitations, headache, dizziness, vision disturbances) or slowed heart rate (e.g., slow pulse, increased dizziness, loss of consciousness). In such a case, treatment should be stopped immediately and the doctor should be contacted. Continuing treatment with midodrine is recommended only if the initial therapy has been effective. If there are significant changes/fluctuations in blood pressure, the use of the medicine should be stopped.

Gutron and other medicines

The patient should tell their doctor about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take. Taking Gutron with certain medicines, such as perphenazine (an antipsychotic medicine, also used in anxiety disorders), amiodarone (a medicine used in heart rhythm disorders), or metoclopramide (a medicine used against nausea and vomiting), may enhance their effects. Interactions may occur with sympathomimetics (ingredients in, e.g., eye or nose drops – phenylephrine, oxymetazoline, pseudoephedrine) and other medicines containing vasoconstrictor substances (e.g., reserpine, guanethidine, antidepressants, antihistamines, thyroid hormones), other medicines used in heart and circulatory system disorders (alpha-adrenergic receptor blockers – e.g., phentolamine, prazosin, dihydroergotamine; beta-adrenergic receptor blockers – e.g., propranolol, metoprolol, atenolol, timolol), digoxin, MAO inhibitors, medicines containing atropine, products containing cortisone (tablets, injections).

Pregnancy and breastfeeding

If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a child, they should consult their doctor before taking this medicine. Gutron should not be taken during pregnancy or breastfeeding. If the patient becomes pregnant during treatment, they should immediately inform their doctor.
