Pharmacological properties
Pharmacodynamics
Feresol has a cauterizing, bactericidal and mummifying effect. The mechanism of its action is the irreversible coagulation of proteins included in the vital structures of the microorganism, resulting in the loss of their functions and further death.
Feresol affects microorganisms of bacterial, viral and fungal origin, as well as protozoa. The cauterizing effect of the drug is due to the destruction of macromolecules of skin cells and mucous membranes. By interacting with body tissues, Feresol provokes chemical burns.
Pharmacokinetics
The drug acts locally and does not penetrate the systemic circulation, therefore there are no data on the pharmacokinetics of Feresol.
Contraindications to the use of Feresol
Moles cannot be removed with Feresol!
The use of the solution is associated with some restrictions. Feresol for papillomas and warts should not be used:
- When treating preschool children . Contraindications are related to the structural features of the skin. The dermis is thin, blood supply and metabolic processes are accelerated. High likelihood of developing allergic reactions. When contacted with healthy areas, chemical burns occur; the active components are quickly absorbed into the bloodstream and can cause general intoxication.
- To remove birthmarks. In this case, the size and structure of the nevus do not matter. Trauma to the surface of moles can contribute to their degeneration into a malignant form and trigger the development of melanoma, the most dangerous form of cancer.
- For treating a large area of skin . If papillomatosis is severe, then problem areas are treated one by one. You cannot apply the solution to a surface larger than 20 cm2 - in this case, there is a high probability of toxins entering the bloodstream and spreading throughout the body.
- For the treatment of mucous membranes . Feresol is not used for warts and papillomas localized on the lips and around the mouth, on the eyelids, in the nasal and ear passages.
- Together with other topical medications . After treatment with a caustic solution, no other ointments or liquids are applied.
- Under a plaster or gauze bandage . The greenhouse effect increases the risk of chemical burns, the development of an allergic reaction and general intoxication of the body.
Genital warts in the intimate area during pregnancy and papillomas on the chest during lactation are not removed. However, “special conditions” are not absolute contraindications for the use of Feresol. You should consult your doctor about the possibility of its use.
Important! If negative reactions occur - itching, irritation or rashes - in places of contact with the skin, the use of Feresol to remove papillomas should be abandoned. Most often, allergies are caused by phenol, which is part of the solution.
Directions for use and dosage
The drug is intended for external use only.
The solution is applied with a thin wooden stick exactly to the treated area of skin. Feresol should not be allowed to come into contact with adjacent healthy areas, as well as mucous membranes.
For filiform warts and papillomas less than 2 mm in size, the drug is applied once. Warts 2–3 mm in size and papillomas more than 2 mm in diameter are smeared 3–4 times at short intervals necessary for the applied solution to dry.
Before removing dry calluses, plantar warts, keratomas and keratinized warts on the hands, horny layers should be removed from their surface. For this purpose, the area to be treated is lubricated with any keratolytic ointment (for example, 10% salicylic ointment), covered with plastic film or compress paper, and a gauze bandage is applied on top or sealed with an adhesive plaster. After some time, the bandage or adhesive plaster is removed, the skin is steamed in hot soapy soda water for 10–15 minutes, after which the horny layers are removed using nail scissors or tongs. After drying the skin, Feresol is applied several times, taking breaks of 3-4 minutes to allow the drug to dry after each application.
Dry calluses and keratomas are treated 3-4 times at intervals of 3-4 minutes, plantar warts and warts on the hands - 7-10 times at intervals of 3-4 minutes.
If Feresol is to be applied repeatedly, it is recommended to lubricate the surrounding skin with zinc paste to avoid burns to healthy areas. After the last portion of the solution has dried, it is necessary to remove the zinc paste with a dry gauze swab.
It is not advisable to remove genital warts on your own. They are treated with a solution of the drug in a clinic setting. The procedure is performed by a dermatovenerologist or urologist. Feresol is applied 1-2 times to each element separately. The interval between applications is 3–4 minutes.
If necessary, 6–8 days after the crust has dried and fallen off, re-treatment is carried out. In total, no more than 4–5 procedures are allowed.
