1. What Gutron is and what it is used for
Gutron raises low blood pressure by constricting small veins and arteries and prevents excessive pooling of blood in the lower limbs. Low blood pressure and pooling of blood in the lower limbs may cause dizziness and cerebral hypoperfusion.
It is indicated for the treatment of severe orthostatic hypotension (a drop in blood pressure upon standing, leading to dizziness or fainting) caused by dysfunction of the autonomic nervous system, when causal treatment is not possible.
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 disorders, hypertension, cardiac arrhythmias;
- severe obstructive or spastic vascular diseases (e.g. cerebral vessel occlusion and spasms);
- acute nephritis, severe renal insufficiency, enlarged prostate gland with prolonged urinary retention, mechanical impairment of urination, urinary retention;
- proliferative diabetic retinopathy (diabetic eye retinal disorders);
- adrenal gland chromaffin cell tumor ( phaeochromocytoma );
- hyperthyroidism;
- narrow-angle glaucoma;
- during pregnancy or breastfeeding.
Warnings and precautions
Before starting treatment with Gutron, discuss it with a doctor or pharmacist.
Special caution is required when using Gutron:
- if the patient suffers from other diseases [particularly right ventricular hypertrophy due to lung disease, intraocular hypertension (increased pressure within the eye), impaired liver or kidney function];
- in case of allergies;
- when taking other medicines concurrently, especially those containing vasoconstrictive substances (see section "Gutron and other medicines");
- during pregnancy and breastfeeding.
All the above-mentioned conditions should be reported to the doctor. The doctor may recommend additional tests to avoid adverse effects.
During treatment, arterial blood pressure should be monitored regularly in the lying, sitting, and standing positions.
At the beginning of treatment, the doctor will assess the risk of developing hypertension in the lying or sitting position.
Be alert for symptoms indicating hypertension (palpitations, headache, dizziness, visual disturbances) or bradycardia (e.g. slow pulse, severe dizziness, loss of consciousness). In such cases, treatment must be stopped immediately and medical advice sought.
Continuation of midodrine treatment is recommended only if initial therapy has proven effective.
If significant changes/fluctuations in blood pressure occur, treatment with the medicine should be discontinued.
Gutron and other medicines
Inform the doctor about all medicines currently or recently taken, as well as any medicines the patient plans to use.
Concurrent use of Gutron with certain medicines, such as perphenazine (an antipsychotic also used in anxiety disorders), amiodarone (used in cardiac arrhythmias), or metoclopramide (an antiemetic) may enhance their effects.
Interactions may occur with sympathomimetics (components of eye or nasal drops – phenylephrine, oxymetazoline, pseudoephedrine) and other agents containing vasoconstrictive substances (e.g. reserpine, guanethidine, antidepressants, antihistamines, thyroid hormones), other drugs used for heart conditions and circulatory diseases (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, or products containing cortisone (tablets, injections).

Gutron should not be taken during pregnancy or breastfeeding.
If a patient becomes pregnant during treatment, she should inform her doctor immediately.
