If a patient has severe kidney failure Omnicom application requires great care.
According to the instructions Omnic recommended for the treatment of urination disorders in BPH (benign prostatic hyperplasia).
- Hypersensitivity to the ingredients of the drug;
- severe hepatic impairment;
- orthostatic hypotension (drop in pressure at the sudden change in body position).
Application Omnicom requires caution in patients with severe renal insufficiency.
Dosing and Administration
According to the instructions Omnic be taken 1 time a day 1 capsule (0, 4 mg). The capsule formulation should be swallowed whole without chewing.

When using Omnic furosemide concentration in serum may slightly decrease, but the concentration of the drug is in the therapeutic range.
The use of diclofenac and warfarin may increase the rate of excretion of Omnicom.
In experiments in vitro (in vitro) revealed no interaction with Omnic diazepam, propranolol, simvastatin.
Simultaneous use with other Omnicom α1-blockers may cause decreased blood pressure.
Application Omnic may in some cases cause a reduction in blood pressure that can lead to fainting. When the first symptoms of hypotension (weakness, dizziness), the patient should sit or lie down and remain in that position until the disappearance of these signs.
