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 the accumulation of blood 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, arterial hypertension, arrhythmias;
• severe vascular disorders (e.g. cerebral artery occlusion and spasm);
• acute kidney inflammation, severe kidney failure, prostate enlargement with prolonged urine retention, mechanical obstruction of urination, urine 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, you should discuss it with your doctor or pharmacist. You should be particularly careful when taking Gutron:

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

You should inform your doctor about all the above situations. The doctor may recommend additional tests to avoid side effects. During treatment, you should regularly check your blood pressure in a lying, sitting, and standing position. At the beginning of treatment, the doctor will assess the risk of developing hypertension in a lying or sitting position. You should pay attention to symptoms indicating the development of hypertension (palpitations, headache, dizziness, vision disturbances) or slowed heart rate (e.g. slow pulse, increased dizziness, loss of consciousness). In such a case, you should immediately stop the treatment and contact your doctor. 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 discontinued.

Gutron and other medicines

You should tell your doctor about all the medicines you are currently taking or have recently taken, as well as any medicines you plan to take. Taking Gutron with certain medicines, such as perfenazine (an antipsychotic medicine, also used in anxiety disorders), amiodarone (a medicine used in arrhythmias), metoclopramide (a medicine used against nausea and vomiting), may enhance their effects. Interactions may occur with sympathomimetics (ingredients of e.g. eye or nose drops - phenylephrine, oxymetazoline, pseudoephedrine) and other medicines containing vasoconstrictor substances (e.g. reserpine, guanethidine, antidepressants, antiallergic medicines, 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).
