Method of administration
FIDAXOMICIN is intended for oral use (by ingestion or via an enteral feeding tube using a syringe, if necessary).
The granules for oral suspension can be taken with or without food.
For instructions on reconstitution of the medicinal product before administration and administration via an enteral feeding tube, see section 6.6.
Instructions for use for the oral suspension:
The bottle should be taken from the refrigerator 15 minutes prior to administration and approximately 10 times gently shaken. Once reconstituted, the oral suspension should only be administered using the oral syringe and adaptor provided by the healthcare professional. The bottle should be stored in a refrigerator after each use.
Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.
Hypersensitivity reactions
Hypersensitivity reactions including severe angioedema have been reported (see section 4.8). If a severe allergic reaction occurs during treatment with fidaxomicin, the medicinal product should be discontinued and appropriate measures taken.
Some patients with hypersensitivity reactions reported a history of allergy to macrolides. Fidaxomicin should be used with caution in patients with a known macrolides allergy.
Renal and hepatic impairment
Due to limited clinical data, fidaxomicin should be used with caution in patients with severe renal impairment or moderate to severe hepatic impairment (see section 5.2).
Pseudomembranous colitis, fulminant or life threatening CDI
Due to limited clinical data, fidaxomicin should be used with caution in patients with pseudomembranous colitis, fulminant or life threatening CDI.
Co-administration of potent P-glycoprotein inhibitors
Co-administration of potent P-glycoprotein inhibitors such as cyclosporine, ketoconazole, erythromycin, clarithromycin, verapamil, dronedarone and amiodarone is not recommended (see sections 4.5 and 5.2). In case fidaxomicin is administered concomitantly with potent P-glycoprotein inhibitors, caution is advised.
FIDAXOMICIN contains sodium
FIDAXOMICIN contains less than 1 mmol sodium (23 mg) per 5 ml suspension, that is to say essentially 'sodium-free'.
Paediatric population
Only one paediatric patient below 6 months of age and no patients with a body weight below 4 kg have been exposed to fidaxomicin in clinical trials. Therefore, fidaxomicin should be used with caution in these patients.
Testing for C. difficile colonization or toxin is not recommended in children younger than 1 year due to high rate of asymptomatic colonisation unless severe diarrhoea is present in infants with risk factors for stasis such as Hirschsprung disease, operated anal atresia or other severe motility disorders. Alternative aetiologies should always be sought and C. difficile enterocolitis be proven.
Sodium benzoate content
This medicine contains 2.5 mg sodium benzoate (E 211) in each ml oral suspension. Sodium benzoate (E 211) may increase jaundice in newborn babies (up to 4 weeks old).
Effect of P-gp inhibitors on fidaxomicin
Fidaxomicin is a substrate of P-gp. Co-administration of single doses of the P-gp inhibitor cyclosporine A and fidaxomicin in healthy volunteers, resulted in a 4- and 2-fold increase in fidaxomicin Cmax and AUC, respectively and in a 9.5 and 4-fold increase in Cmax and AUC, respectively, of the main active metabolite OP-1118. As the clinical relevance of this increase in exposure is unclear, co-administration of potent inhibitors of P-gp, such as cyclosporine, ketoconazole, erythromycin, clarithromycin, verapamil, dronedarone and amiodarone is not recommended (see section 4.4 and 5.2).
Effect of fidaxomicin on P-gp substrates
Fidaxomicin may be a mild to moderate inhibitor of intestinal P-gp.
Fidaxomicin (200 mg twice daily) had a small but not clinically relevant effect on digoxin exposure. However, a larger effect on P-gp substrates with lower bioavailability more sensitive to intestinal P-gp inhibition such as dabigatran etexilat cannot be excluded.
Effect of fidaxomicin on other transporters
Fidaxomicin does not have a clinically significant effect on the exposure of rosuvastatin, a substrate for the transporters OATP2B1 and BCRP. Co-administration of 200 mg fidaxomicin twice daily with a single dose of 10 mg rosuvastatin to healthy subjects did not have a clinically significant effect on the AUCinf of rosuvastatin.
Paediatric population
Interaction studies have only been performed in adults.
Pregnancy
There are no data available from the use of fidaxomicin in pregnant women. Animal studies did not indicate direct or indirect harmful effects with respect to reproductive toxicity. As a precautionary measure, it is preferable to avoid the use of fidaxomicin during pregnancy.
Breast-feeding
It is unknown whether fidaxomicin and its metabolites are excreted in human milk. Although no effects on the breastfed newborns/infants are anticipated since the systemic exposure to fidaxomicin is low, a risk to the newborns/infants cannot be excluded. A decision must be made whether to discontinue breast-feeding or to discontinue/abstain from fidaxomicin therapy, taking into account the benefit of breast feeding for the child and the benefit of therapy for the woman.
Fertility
Fidaxomicin had no effects on fertility when evaluated in rats (see section 5.3).
FIDAXOMICIN has no or negligible influence on the ability to drive and use machines.
Summary of the safety profile
The most common adverse reactions are vomiting (1.2%), nausea (2.7%) and constipation (1.2%).
Tabulated list of adverse reactions
Table 2 displays adverse reactions associated with twice daily administration of fidaxomicin in the treatment of C. difficile infection, reported in at least two patients, presented by system organ class.
The frequency of adverse reactions is defined as follows: very common (≥1/10); common (≥1/100 to <1/10); uncommon (≥1/1,000 to <1/100); rare (≥1/10,000 to <1/1,000); very rare (<1/10,000), not known (cannot be estimated from the available data). Within each frequency grouping, adverse reactions are presented in order of decreasing seriousness.

Description of selected adverse reactions
Acute hypersensitivity reactions, such as angioedema and dyspnea, have been reported during post-marketing (see section 4.3 and 4.4).
Paediatric population
The safety and efficacy of fidaxomicin has been evaluated in 136 patients from birth to less than 18 years of age. Frequency, type and severity of adverse reactions in children are expected to be the same as in adults. In addition to the ADRs shown in table 2, two cases of urticaria were reported.
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 or search for MHRA Yellow Card in the Google Play or Apple App Store.
No adverse reactions for acute overdose have been reported during clinical studies or from post-marketing data. However, the potential for adverse reactions cannot be ruled out and general supportive measures are recommended.
