Mechanism of action
The medicinal activity of the acne medication is explained by the presence of fusidic acid in its composition. This natural antibiotic is absorbed by the skin and then enters the body. Metabolism of the substance occurs in the structures of the liver. It is excreted along with urine and bile.
Fusidic acid disrupts the production of protein by the cell walls of pathogenic bacteria. As a result, they stop reproducing and gradually die. The active substance is active against gram-negative and gram-positive microorganisms.
The use of ointment or cream in the treatment of acne caused by E. coli, Proteus, fungi and salmonella does not give a positive result, since fusidic acid does not have an antibacterial effect on these pathogens.

Reviews
Tatyana, 33 years old, Syktyvkar. Despite the fact that this drug is intended for external use, it is a powerful antibiotic.
About 4 months ago I suffered from a severe flu, after which a small spot appeared on my left arm, which, under the influence of sunlight, increased in size and became darker. To avoid trouble, I decided to see a dermatologist.
The doctor found that this is not a birthmark, but a type of lichen that many residents of large cities face.
For treatment, the doctor prescribed the drug Fucidin. I smeared it on the problem area until the pigmentation completely disappeared. The dark spot began to gradually lighten and become less visible after applying the ointment. After 1.5 weeks there was no trace left of him.
The medicine is effective, inexpensive and sold in almost any pharmacy. If the doctor had prescribed another drug for me, the therapy might have been delayed for a long time.
Now I bought another tube of medication to use if necessary.
Anatoly, 39 years old, Volgodonsk. I work on a woodworking machine. Recently I severely burned my hand when I was changing a casing element on a machine engine. It turned out that as a result of this idea he received a severe burn on his palm. On the same day I went to the hospital.
The doctor recommended a course of treatment with Fucidin cream. Only 2 weeks of sick leave was enough for the patient to restore damaged skin. A small scar remained at the site of the burn.
In the first days of using the ointment, slight swelling appeared in the treated area, which disappeared on its own in the subsequent days of therapy.
Alla, 43 years old, Samara. This ointment is always in our home medicine cabinet. It copes well with suppuration and inflammatory processes in the epidermis.
The medication works effectively and in the shortest possible time. About a year ago, with its help, I was able to quickly cure lichen.
Now I use Fucidin to prevent the appearance of pimples on different parts of the body.
Recently I decided to try to eliminate the rashes on my husband’s back. The medication also coped with this task. There were no adverse reactions, neither for me nor for my husband.
Alexey, 46 years old, Tver. I recommend this medication to my patients to eliminate various skin problems caused by bacterial infections.
The ointment quickly eliminates boils, boils, acne and other types of dermatological formations. The pronounced effect of the medication begins after the initial treatment. At the same time, the active substances are not absorbed into the systemic circulation.
No cases of resistance were observed. The medicine is sold in almost any city pharmacy.

Reviews about Fucidin
Since the range of indications for the use of this ointment or cream is quite wide, it is used quite often and in various cases.
Accordingly, reviews about Fucidin are very different. Firstly, there are many reports of Fucidin being used for acne. On forums where people, mostly young people, suffering from various skin infections and rashes communicate, there are reviews of attempts to recover using this antibiotic. It must be said that its effectiveness is not always confirmed. Some discussion participants expressed disappointment: “Fucidin doesn’t help at all!”, “I’ll throw away this tube - it doesn’t work!” But often from the stories it becomes clear that the rules of use and the time of application were not followed. For example, one girl, after anointing her face with Fucidin for two days, discovered that new acne appeared and stopped treatment.
Secondly, this drug is often used in pediatrics. The reviews here are much more positive. Fucidin allows you to restore health to the skin of babies with inflammation and pustular rashes. Cases of cure of large boils in children have been described.
Of course, before using Fucidin, it is necessary to determine the diagnosis and, preferably, identify the causative agent of the infection. At the same time, the effectiveness of using this (and any) antibiotic will increase significantly.
