Pharmacological properties

Farisil is a combined antiseptic drug for topical use in infectious and inflammatory diseases of the oral cavity and throat. the effect of the drug is provided by the action of the components that make up its composition.

Chlorhexidine is an antiseptic, the effect of which is due to surface cationic properties, which leads to a violation of the integrity of the membranes of microorganisms. The drug is active against most bacteria, fungi and viruses, has a microbicidal effect.

Benzocaine, which is part of the drug, has a local anesthetic (analgesic) effect. Reduces sore throat, tickle, pain when swallowing.

About 30% of chlorhexidine is absorbed in the oral cavity, excreted with saliva during the day, which significantly prolongs its effect. Benzocaine is almost not absorbed in the oral cavity.

Application

1 tablet should be slowly absorbed in the oral cavity.

Adults and children over the age of 12 take 1 tablet every 2-3 hours, but no more than 8 tablets per day.

special instructions

Patients with intolerance to ether-type anesthetics (Novocaine), parabens can also be hypersensitive to benzocaine. the drug should be used with caution in children, elderly patients and seriously ill patients, since they are more sensitive to benzocaine, and excess doses can lead to methemoglobinemia. tablets should not be bitten and swallowed, since the effect of the drug is local and is possible only with direct contact with the affected area.

Use during pregnancy and lactation.
