Pregnancy; the period of breastfeeding; diseases of the cardiovascular system, in which an increase in the number of heartbeats may be undesirable: atrial fibrillation, tachycardia,chronic heart failure, ischemic heart disease, mitral stenosis, arterial hypertension, acute bleeding; thyrotoxicosis (tachycardia may be worse); increased body temperature (may still increase due to suppression of activity of sweat glands); reflux-esophagitis, hernia of the esophageal opening of the diaphragm, combined with reflux esophagitis (decreased esophageal and gastric motility and relaxation of the lower esophageal sphincter may contribute to slowing the emptying of the stomach and enhancing gastroesophageal reflux through the sphincter with impaired function); diseases of the gastrointestinal tract, accompanied by obstruction: achalasia and stenosis of the pylorus (there may be a decrease in motor and tone, leading to obstruction and delay in stomach contents); atony of the intestine in elderly patients or weakened patients (possible the development of obstruction), paralytic ileus (possible the development of obstruction); diseases with increased intraocular pressure: closed-angle (mydriatic effect, leading to increased intraocular pressure,can cause acute attack) and open-angle glaucoma (mydriatic effect may cause some increase in intraocular pressure, correction of therapy may be required), age over 40 (risk of undiagnosed glaucoma); nonspecific ulcerative colitis (high doses can inhibit intestinal motility, increasing the likelihood of paralytic intestinal obstruction, and possibly the manifestation or exacerbation of such a serious complication as a toxic megacolon); dryness of the oral mucosa (long-term use may cause further intensification of xerostomia); hepatic insufficiency (decreased metabolism) and renal failure (risk of side effects due to reduced excretion); chronic lung diseases, especially in young children and weakened patients (a decrease in bronchial secretion can lead to a thickening of the secret and the formation of congestion in the bronchi); myasthenia gravis (the condition may worsen due to inhibition of the action of acetylcholine); autonomic (autonomic) neuropathy (urinary retention and paralysis of accommodation may be intensified),hypertrophy of the prostate without obstruction of the urinary tract, urinary retention or predisposition to it, or diseases accompanied by obstruction of the urinary tract (including the bladder neck due to prostatic hypertrophy); gestosis (hypertension is possible); brain damage in children (effects from the central nervous system may increase); Down's disease (possibly an unusual dilatation of the pupils and an increase in the number of heartbeats); central paralysis in children (reaction to anticholinergic drugs may be most pronounced).
Patients with diabetes mellitus and people on a diet with a reduced carbohydrate content.
If you have any of these diseases, consult a doctor before taking the drug.
