During the period of application of the drug, contact lenses should not be worn.
It does not affect the size of the pupil, with closed-angle glaucoma used only in combination with miotics. When transferring the patient to betaxolol After treatment with several antiglaucoma drugs, the latter are gradually phased out. With insufficient reduction of intraocular pressure simultaneously with betaxolol, you can use pilocarpine or other myotics and / or epinephrine, and / or carbanhydrase inhibitors. With prolonged use there is a decrease in sensitivity to betaxolol.
After instillation, the bottle must be closed immediately.
The cardiovascular system
Special care is required in the treatment of patients who have a history of conduction disorders or heart failure.
Diabetes
It is necessary with special caution to prescribe beta-blockers to patients with spontaneous hypoglycemia or patients with diabetes mellitus,who receive insulin or oral hypoglycemic drugs, since beta-blockers may mask signs of acute hypoglycemia.
Hyperthyroidism
Beta-adrenoblockers can mask symptoms of hyperthyroidism (tachycardia), therefore, one should not abruptly cancel them if there is a suspicion of hyperthyroidism - a thyrotoxic crisis may develop.
Respiratory system
In patients with pulmonary disease, asthma attacks and other pulmonary complications are possible with treatment with betaxolol.
Surgery
Prior to the application of general anesthesia, beta-blockers should be gradually withdrawn, as they reduce the ability of the heart to respond to signals of a sympathetic nature.
Muscle weakness
Beta-adrenoblockers can increase the signs of muscle weakness, which are similar to the symptoms of a malignant myasthenia gravis (diplopia, ptosis, general weakness).
Patients who have a history of atopy or acute anaphylactic reaction to various allergens may be more sensitive to repeated, accidental, diagnostic or therapeutic administration of the relevant allergens during administration of beta-adrenergic blockers and not respond to conventional doses of epinephrine,used to eliminate allergic reaction.
