SUMMARY OF PRODUCT CHARACTERISTICS
1 NAME OF THE MEDICINAL PRODUCT
Daktarin Powder
2 QUALITATIVE AND QUANTITATIVE COMPOSITION
Daktarin powder contains miconazole nitrate 2.0% w/w.
(Each gram of powder contains 20mg of miconazole nitrate)
For excipients, see Section 6.1
3 PHARMACEUTICAL FORM
Cutaneous powder
White powder
4 CLINICAL PARTICULARS
4.1 Therapeutic indications
For the treatment of mycotic infections of the skin and superinfections due to Gram positive bacteria.
4.2 Posology and method of administration
Daktarin powder is for cutaneous administration.
Adults
Twice daily application of powder to the lesions, treatment being prolonged for some 10 days after all lesions have disappeared to prevent relapse.
Elderly and children As for adults.
4.3 Contraindications
Hypersensitivity to the active substance(s), other imidazole derivatives or to any of the excipients listed in section 6.1
The powder should not be recommended for the treatment of infections of the hair and nails.
4.4 Special warnings and precautions for use
Severe hypersensitivity reactions, including anaphylaxis and angioedema, have been reported during treatment with Daktarin Powder and with other miconazole topical formulations (see Adverse Reactions). If a reaction suggesting hypersensitivity or irritation should occur, the treatment should be discontinued.
Daktarin Powder must not come into contact with the mucosa of the eyes.
Daktarin Powder contains talc. Avoid inhalation of the powder to prevent irritation of the airways. In particular, when treating infants and children, careful application should be used to prevent inhalation by the child.
4.5 Interaction with other medicinal products and other forms of interaction
Miconazole administered systemically is known to inhibit CYP3A4/2C9. Due to the limited systemic availability after topical application, clinically relevant interactions are rare. However, in patients on oral anticoagulants, such as warfarin, caution should be exercised and anticoagulant effect should be monitored.
4.6 Fertility, pregnancy and lactation
Pregnancy
In animals, miconazole nitrate has shown no teratogenic effects but is foetotoxic at high oral doses. Only small amounts of miconazole nitrate are absorbed following topical administration. However, as with other imidazoles, miconazole nitrate should be used with caution during pregnancy.
Topically applied miconazole is minimally absorbed into the systemic circulation and it is not known whether miconazole is excreted in human breast milk. Caution should be exercised when using topically applied miconazole products during lactation.
4.7 Effects on ability to drive and use machines
Not applicable.
4.8 Undesirable effects
Adverse drug reactions reported among 834 patients who received miconazole nitrate 2% cream (n=426) and/or placebo cream base (n=408) in 21 doubleblind clinical trials are presented in Table 1 below. Moreover, adverse drug reactions from spontaneous reports during the worldwide post-marketing experience with Daktarin that meet threshold criteria are included in Table 1. The adverse drug reactions are ranked by frequency, using the following convention:
Very common >1/10
Common >1/100 and <1/10
Uncommon >1/1,000 and <1/100
Rare >1/10,000 and <1/1,000
Very rare <1/10,000, including isolated reports
Adverse reactions obtained from clinical studies and post-marketing surveillance are presented by frequency category based on incidence in clinical trials or epidemiology studies, when known.

Reporting of suspected adverse reactions
Reporting suspected adverse reactions 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 at: www.mhra.gov.uk/yellowcard.’
4.9 Overdose
Symptoms
Cutaneous use: Excessive use can result in skin irritation, which usually disappears after discontinuation of therapy.
Treatment
Daktarin Powder is intended for cutaneous use, not for oral use. If accidental ingestion of large quantities of the product occurs, use appropriate supportive care.
Accidential inhalation of talc-containing powder: Massive accidental aspiration of Daktarin Powder may cause impaction blockage of airways. Respiratory arrest should be treated with intensive supportive therapy and oxygen. If respiration is compromised, endotracheal intubation, removal of impacted material, and assisted breathing should be considered.
5 PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic classification: (Antifungals for dermatological/topical use; imidazole derivative) ATC code: D01A C02.
Miconazole nitrate is an imidazole antifungal agent and may act by interfering with the permeability of the fungal cell membrane. It possesses a wide antifungal spectrum and has some antibacterial activity.
5.2 Pharmacokinetic properties
Absorption: There is little absorption through skin or mucous membranes when miconazole nitrate is applied topically.
Distribution: Absorbed miconazole is bound to plasma proteins (88.2%) and red blood cells (10.6%).
Metabolism and Excretion: The small amount of miconazole that is absorbed is eliminated predominantly in faeces as both unchanged drug and metabolites.
5.3 Preclinical safety data
Preclinical data reveal no special hazard for humans based on conventional studies of local irritation, single and repeated dose toxicity, genotoxicity, and toxicity to reproduction.
