Treatment of non-severe, superficial, non-extensive, primary skin infections caused by microorganisms that are sensitive to Fulosin, especially of infections caused by Staphylococcus.
Primary skin infections that may be expected to respond to treatment with Fulosin applied topically include: impetigo contagiosa, superficial folliculitis, sycosis barbae, paronychia and erythrasma.
Consideration should be given to official guidance on the appropriate use of antibacterial agents..
Fulosin 20 mg/g cream is indicated either alone or in combination with systemic therapy, in the treatment of primary and secondary skin infections caused by sensitive strains of Staphylococcus aureus, Streptococcus spp and Corynebacterium minutissimum. Primary skin infections that may be expected to respond to treatment with fusidic acid applied topically include: impetigo contagiosa, superficial folliculitis, sycosis barbae, paronychia and erythrasma; also such secondary skin infections as infected eczematoid dermatitis, infected contact dermatitis and infected cuts/abrasions.
Posology
Adults and children:
Uncovered lesions: apply gently three or four times daily.
Covered lesions: less frequent applications may be adequate.
Method of administration:
Cutaneous use

Method of administration
Cutaneous use.
Fulosin 20 mg/g cream is contraindicated in patients with known hypersensitivity to Fulosin or to any of the excipients used in the product.
Bacterial resistance has been reported to occur with the use of Fulosin.
Extended or recurrent use may increase the risk of developing contact sensitisation.
When Fulosin 20 mg/g cream is used on the face, care should be taken to avoid the eyes, because Fulosin can cause irritation of the conjunctiva.
Fulosin 20 mg/g cream contains butylhydroxyanisole, cetyl alcohol and potassium sorbate which may cause local skin reactions (e.g. contact dermatitis). Butylhydroxyanisole may also cause irritation to the eyes and mucous membranes.
Bacterial resistance among staphylococcus aureus has been reported to occur with the use of topical Fulosin. As with all antibiotics, extended or recurrent use may increase the risk of developing antibiotic resistance.
Extended or recurrent use may increase the risk of developing contact sensitisation.
Fulosin cream contains butylhydroxyanisole, cetyl alcohol and potassium sorbate. These excipients may cause local skin reactions (e.g. contact dermatitis). Butylhydroxyanisole may also cause irritation to the eyes and mucous membranes. Fulosin cream should therefore be used with care when applied in the proximity of the eyes.
Fulosin cream has no or negligible influence on the ability to drive and use machines.
Fulosin administered topically has no or negligible influence on the ability to drive and use machines.
The estimation of the frequency of undesirable effects is based on a pooled analysis of data from clinical trials and from spontaneous reporting,
Based on pooled data from clinical studies including 4754 patients who received Fulosin 20mg/g cream or Fulosin ointment, the frequency of undesirable effects is 2.3%.
The most frequently reported adverse reactions during treatment are various skin reactions such as pruritus and rash, followed by application site conditions such as pain and irritation, which all occurred in less than 1% of patients.
Hypersensitivity and angioedema have been reported.

Reporting of suspected adverse reactions
Reporting suspected adverse reaction after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme Website: www.mhra.gov.uk/yellowcard.

Overdose is unlikely.
Unless hypersensitivity to Fulosin or any of the excipients exist, accidental ingestion of Fulosin 20mg/g cream is unlikely to cause any harm. The total quantity of Fulosin (30g Fulosin 20mg/g cream contains 600mg Fulosin) will usually not exceed the approved total daily oral dose of Fulosin containing products except in children aged less than 1 year and weighing ≤10kg.
Although in this instance a child of this particular age group is unlikely to ingest a whole tube of Fulosin 20mg/g cream. The concentration of the excipients is too low to constitute a safety risk.

Pharmacotherapeutic group: other antibiotics for topical use, ATC code: D06AX01
Active mechanism:
Fulosin belongs to a unique group of antibiotics, the fusidanes, which act to inhibit bacterial protein synthesis by blocking the lengthening of factor G. This is to prevent it from associating with ribosomes and GTP, thus preventing energy supply to the synthesis process.
As it is the only type of drug available in this family of drugs, there have been no reports of cross resistance to Fulosin.
Resistance mechanism(s):
Resistance for Fulosin can vary geographically and information about local resistance patterns should be obtained through a local microbiology laboratory. In general, resistance occurs in 1-10 % of Staphylococcus aureus and 10-20 % of coagulase negative staphylococcus. Cross-resistance between Fulosin hydrophilic cream 20 mg/g and other antibiotics has not been reported.
Breakpoints:
The following MIC values are recommended to distinguish sensitive and non-sensitive germs: S ≤ 1 µg/ml and R > 1 µg/ml. This breakpoint should be used for the systemic use of Fulosin. In general, no breakpoints are established for the topical use of antibiotics.
Sensitivity:
The sensitivity of organisms to Fulosin is based on the in vitro sensitivity and plasma concentrations that are achieved after systemic therapy. Local treatment causes higher peak concentrations as compared to plasma. However, it is not known how the kinetics of the cream after local application may change the effectiveness of the cream.
| Commonly susceptible species | Staphylococcus aureus and Staphylococcus epidermis (including methycillin resistant and beta lactamase producing strains); Corynebacterium minutissimum; Clostridium spp.; Peptococcus spp.; Peptostreptococcus spp.; Neiseria spp.; Bacteroides fragilis. |
| Inherently resistant organisms | Streptococcus pyogenes; Streptococcus pneumoniae; Streptococci viridans; most gram negative bacilli including Haemophilus influenza; Enterobactericeae; Pseudomonas spp.; Escherichia coli and Klebsiella pneumoniae. |

Fusidic acid is a potent antibacterial agent. Fusidic acid and its salts show fat and water solubility and strong surface activity and exhibit unusual ability to penetrate intact skin. Concentrations of 0.03 - 0.12 mcg fusidic acid per ml inhibit nearly all strains of Staphylococcus aureus. Topical application of fusidic acid is also effective against streptococci, corynebacteria, neisseria and certain clostridia.
In Vitro studies show that Fulosin can penetrate intact human skin. The degree of penetration depends on factors such as the duration of exposure to Fulosin and the condition of the skin. Fulosin is excreted mainly in the bile with little excreted in the urine.
