secnidazole 2000 MG Oral Granules [Solosec]

INDICATIONS AND USAGE SOLOSEC ® is a nitroimidazole antimicrobial indicated for: Treatment of bacterial vaginosis in female patients 12 years of age and older. ( 1.1 ) Treatment of trichomoniasis in patients 12 years of age and older. ( 1.2 ) To reduce the development of drug-resistant bacteria and maintain the effectiveness of SOLOSEC and other antibacterial drugs, SOLOSEC should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria. ( 1.3 ) 1.1 Bacterial Vaginosis SOLOSEC is indicated for the treatment of bacterial vaginosis in female patients 12 years of age and older [see Use in Specific Populations (8.1) and Clinical Studies (14) ]. 1.2 Trichomoniasis SOLOSEC is indicated for the treatment of trichomoniasis caused by Trichomonas vaginalis in patients 12 years of age and older. Because trichomoniasis is a sexually transmitted disease with potentially serious sequelae, treat partners of infected patients simultaneously in order to prevent reinfection [see Dosage and Administration (2.2) and Clinical Studies (14.2) ] . 1.3 Usage To reduce the development of drug-resistant bacteria and maintain the effectiveness of SOLOSEC and other antibacterial drugs, SOLOSEC should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

DOSAGE AND ADMINISTRATION Bacterial Vaginosis (female patients 12 years of age and older): Administer a single 2-gram packet of granules once orally, without regard to the timing of meals. ( 2.1 ) Trichomoniasis (patients 12 years of age and older): Administer a single 2-gram packet of granules once orally, without regard to the timing of meals. Treat sexual partners with the same dose and at the same time. ( 2.2 ) Sprinkle entire contents of packet onto applesauce, yogurt or pudding and consume all of the mixture within 30 minutes without chewing or crunching the granules. A glass of water may be taken after the administration of SOLOSEC to aid in swallowing. ( 2.3 ) SOLOSEC is not intended to be dissolved in any liquid. ( 2.3 ) 2.1 Recommended Dosage for Bacterial Vaginosis The recommended dosage of SOLOSEC for the treatment of bacterial vaginosis in female patients 12 years of age and older is a single 2-gram packet of granules taken once orally, without regard to the timing of meals [see Clinical Pharmacology (12.3) ] . 2.2 Recommended Dosage for Trichomoniasis The recommended dosage of SOLOSEC for the treatment of trichomoniasis in patients 12 years of age and older is a single 2-gram packet of granules taken once orally, without regard to the timing of meals [see Clinical Pharmacology (12.3) ] . Since trichomoniasis is a sexually transmitted disease, treat sexual partners with the same dose and at the same time [see Indications and Usage (1.2) ] . 2.3 Instructions for the Preparation and Administration of SOLOSEC Open the SOLOSEC packet by folding over the corner (marked by an arrow) and tearing across the top. Sprinkle the entire contents of the SOLOSEC packet onto applesauce, yogurt or pudding [see Clinical Pharmacology (12.3) ] . The granules will not dissolve. Consume all of the mixture within 30 minutes without chewing or crunching the granules. A glass of water may be taken after the administration of SOLOSEC to aid in swallowing. The granules are not intended to be dissolved in any liquid. Avoid consumption of alcoholic beverages and preparations containing ethanol or propylene glycol during treatment with SOLOSEC and for at least 2 days after completing therapy [see Adverse Reactions (6.2) , Drug Interactions (7.2) , and Clinical Pharmacology (12.3) ].

WARNINGS AND PRECAUTIONS Vulvovaginal Candidiasis: This may develop with SOLOSEC and require treatment with an antifungal agent. ( 5.1 ) Potential Risk for Carcinogenicity : Carcinogenicity has been seen in mice and rats treated chronically with nitroimidazole derivatives, which are structurally related to secnidazole. It is unclear if the positive tumor findings in lifetime rodent studies indicate a risk to patients taking a single dose of SOLOSEC to treat bacterial vaginosis. Avoid chronic use. ( 5.2 ) 5.1 Vulvovaginal Candidiasis The use of SOLOSEC may result in vulvovaginal candidiasis. In controlled clinical trials of non-pregnant women with bacterial vaginosis, vulvovaginal candidiasis developed in 19/197 (9.6%) of patients who received 2 g SOLOSEC and 4/136 (2.9%) subjects who received placebo. In a controlled clinical trial of non-pregnant female patients with trichomoniasis, vulvovaginal candidiasis developed in 2/74 (2.7%) of patients who received 2 g SOLOSEC and 0/73 (0%) subjects who received placebo [see Adverse Reactions (6.1) ] . Symptomatic vulvovaginal candidiasis may require treatment with an antifungal agent. 5.2 Potential Risk for Carcinogenicity Carcinogenicity has been seen in mice and rats treated chronically with nitroimidazole derivatives which are structurally related to secnidazole . It is unclear if the positive tumor findings in lifetime rodent studies of these nitroimidazoles indicate a risk to patients taking a single dose of SOLOSEC to treat bacterial vaginosis. Avoid chronic use of SOLOSEC [see Nonclinical Toxicology (13.1) ] 5.3 Risk of Development of Drug Resistance Prescribing SOLOSEC in the absence of proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.

4. CONTRAINDICATIONS SOLOSEC is contraindicated: In patients who have shown hypersensitivity to secnidazole, or other nitroimidazole derivatives. In patients with Cockayne syndrome: Severe irreversible hepatotoxicity/acute liver failure with fatal outcomes have been reported after initiation of metronidazole, another nitroimidazole drug, structurally related to secnidazole, in patients with Cockayne syndrome [see Adverse Reactions (6.2) ] . History of hypersensitivity to secnidazole, or other nitroimidazole derivatives. ( 4 ) Patients with Cockayne syndrome. ( 4 , 6.2 )

Mechanism of Action SOLOSEC is a nitroimidazole antimicrobial drug [see Microbiology (12.4) ].
