Indications & Usage
1 INDICATIONS AND USAGE Oseltamivir phosphate capsules are an influenza neuraminidase inhibitor (NAI) indicated for: Treatment of acute, uncomplicated influenza A and B in patients 2 weeks of age and older who have been symptomatic for no more than 48 hours. ( 1.1 ) Prophylaxis of influenza A and B in patients 1 year and older. ( 1.2 ) Limitations of Use: Not a substitute for annual influenza vaccination. ( 1.3 ) Consider available information on influenza drug susceptibility patterns and treatment effects when deciding whether to use. ( 1.3 ) Not recommended for patients with end-stage renal disease not undergoing dialysis. ( 1.3 ) 1.1 Treatment of Influenza Oseltamivir phosphate capsules are indicated for the treatment of acute, uncomplicated illness due to influenza A and B infection in patients 2 weeks of age and older who have been symptomatic for no more than 48 hours. 1.2 Prophylaxis of Influenza Oseltamivir phosphate capsules are indicated for the prophylaxis of influenza A and B in patients 1 year and older. 1.3 Limitations of Use Oseltamivir phosphate capsules are not a substitute for early influenza vaccination on an annual basis as recommended by the Centers for Disease Control and Prevention Advisory Committee on Immunization Practices. Influenza viruses change over time. Emergence of resistance substitutions could decrease drug effectiveness. Other factors (for example, changes in viral virulence) might also diminish clinical benefit of antiviral drugs. Prescribers should consider available information on influenza drug susceptibility patterns and treatment effects when deciding whether to use oseltamivir phosphate capsules [see Microbiology (12.4) ]. Oseltamivir phosphate capsules are not recommended for patients with end-stage renal disease not undergoing dialysis [see Dosage and Administration (2.4) and Use in Specific Populations (8.6) ].

The capsules may be taken with or without food; however, tolerability may be enhanced if oseltamivir phosphate capsules are taken with food. Adjust the oseltamivir phosphate dosage in patients with moderate or severe renal impairment [see Dosage and Administration (2.4) ]. For patients who cannot swallow capsules, oseltamivir phosphate for oral suspension is the preferred formulation. When oseltamivir phosphate for oral suspension is not available from wholesaler or the manufacturer, oseltamivir phosphate capsules may be opened and mixed with sweetened liquids such as regular or sugar-free chocolate syrup, corn syrup, caramel topping, or light brown sugar (dissolved in water). During emergency situations and when neither the oral suspension or the age-appropriate strengths of oseltamivir phosphate capsules to mix with sweetened liquids are available, then a pharmacist may compound an emergency supply of oral suspension from oseltamivir phosphate 75 mg capsules [see Dosage and Administration (2.6) ]. 2.2 Recommended Dosage for Treatment of Influenza Initiate treatment with oseltamivir phosphate capsules within 48 hours of influenza symptom onset. Adults and Adolescents (13 years of age and older) The recommended oral dosage of oseltamivir phosphate for treatment of influenza in adults and adolescents 13 years and older is 75 mg twice daily (one 75 mg capsule twice daily) for 5 days. Pediatric Patients (2 weeks of age through 12 years of age) Table 1 displays the recommended oral dosage of oseltamivir phosphate for treatment of influenza in pediatric patients 2 weeks of age through 12 years of age and provides information about prescribing the capsule or the formulation for oral suspension. 2.3 Recommended Dosage for Prophylaxis of Influenza Initiate post-exposure prophylaxis with oseltamivir phosphate within 48 hours following close contact with an infected individual. Initiate seasonal prophylaxis with oseltamivir phosphate during a community outbreak. Adults and Adolescents (13 years of age and older) The recommended dosage of oseltamivir phosphate for prophylaxis of influenza in adults and adolescents 13 years and older is 75 mg orally once daily (one 75 mg capsule once daily) for at least 10 days following close contact with an infected individual and up to 6 weeks during a community outbreak. In immunocompromised patients, oseltamivir phosphate may be continued for up to 12 weeks [see Use in Specific Populations (8.9 )]. The duration of protection lasts for as long as oseltamivir phosphate dosing is continued. Pediatric Patients (1 year to 12 years of age) Table 1 displays the recommended oral dosage of oseltamivir phosphate for prophylaxis of influenza in pediatric patients 1 year to 12 years of age based on body weight and provides information about prescribing the capsule or the formulation for oral suspension. Prophylaxis in pediatric patients is recommended for 10 days following close contact with an infected individual and up to 6 weeks during a community outbreak [see Use in Specific Populations (8.4) and Clinical Studies (14.2)]. Table 1 Oseltamivir Phosphate Dosage Recommendations in Pediatric Patients for Treatment and Prophylaxis of Influenza * The recommended duration for post-exposure prophylaxis is 10 days and the recommended duration for community outbreak (seasonal/pre-exposure) prophylaxis is up to 6 weeks (or up to 12 weeks in immunocompromised patients).

The following emergency preparation instructions will provide one patient with enough oseltamivir phosphate for a 5-day course of treatment of influenza or a 10-day course of prophylaxis of influenza: Step #1 : Determine the dosage of oseltamivir phosphate for the patient [ see Dosage and Administration ( 2.2 , 2.3 , and 2.4 ) ] then determine the total volume of oral suspension needed to be prepared (see Table 3). Table 3 Emergency Preparation: Volume of Prepared Oral Suspension (6 mg per mL) Based Upon Oseltamivir Phosphate Capsules Dose * If the oseltamivir phosphate dose is between the doses listed, use the greater listed dose to determine the total volume of prepared oral suspension. Oseltamivir Phosphate Dose* Total Volume to Prepare per Patient 15 mg or less 37.5 mL 30 mg 75 mL 45 mg 100 mL 60 mg 125 mL 75 mg 150 mL Step #2 : Preparation must be performed with only one of the following vehicles (other vehicles have not been studied): Cherry Syrup (Humco®), Ora-Sweet® SF (sugar-free) (Paddock Laboratories), or simple syrup. Determine the number of capsules and the amount of water and vehicle needed to prepare the total volume (see Table 3) of prepared oral suspension (6 mg per mL) for a complete treatment or prophylaxis course (see Table 4). Table 4 Emergency Preparation: Number of Oseltamivir Phosphate 75 mg Capsules and Amount of Water and Vehicle Needed to Prepare the Total Volume of a Prepared Oral Suspension (6 mg per mL) * Includes overage to ensure all doses can be delivered Total Volume of Prepared Oral Suspension 37.5 mL 75 mL 100 mL 125 mL 150 mL Number of Oseltamivir Phosphate 75 mg Capsules (Total Strength)* 3 (225 mg) 6 (450 mg) 8 (600 mg) 10 (750 mg) 12 (900 mg) Amount of Water 2.5 mL 5 mL 7 mL 8 mL 10 mL Volume of Vehicle Cherry Syrup (Humco ® ) OR Ora-Sweet ® SF (Paddock Laboratories) OR simple syrup 34.5 mL 69 mL 91 mL 115 mL 137 mL Step #3 : Follow the instructions below for preparing the 75 mg oseltamivir phosphate capsules to produce the oral suspension (6 mg per mL): a. Place the specified amount of water into a polyethylene terephthalate (PET) or glass bottle (see Table 4). Constitution in other bottle types is not recommended because there is no stability data with other bottle types. b. Carefully separate the capsule body and cap and pour the contents of the required number of oseltamivir phosphate 75 mg capsules into the PET or glass bottle. c. Gently swirl the suspension to ensure adequate wetting of the oseltamivir phosphate powder for at least 2 minutes. d. Slowly add the specified amount of vehicle to the bottle. e. Close the bottle using a child-resistant cap and shake well for 30 seconds to completely dissolve the active drug and to ensure homogeneous distribution of the dissolved drug in the resulting suspension. The active drug, oseltamivir phosphate, readily dissolves in the specified vehicles. The suspension is caused by inert ingredients of oseltamivir phosphate capsules which are insoluble in these vehicles. f. Put an ancillary label on the bottle indicating “Shake Well Before Use.” g. Instruct the parent or caregiver that any unused suspension remaining in the bottle following completion of therapy must be discarded by either affixing an ancillary label to the bottle or adding a statement to the pharmacy label instructions. h. Place a pharmacy label on the bottle that includes the patient’s name, dosing instructions, drug name and any other required information to be in compliance with all State and Federal Pharmacy Regulations. Place an appropriate expiration date on the label according to storage conditions below. i. Include the recommended dosage on the pharmacy label as per Tables 1 and 2 [see Dosage and Administration ( 2.2 , 2.3 , and 2.4 )]. j. Store the prepared oral suspension in glass or PET bottles either: • In a refrigerator [2° to 8°C (36° to 46°F)]: Stable for 5 weeks when stored in a refrigerator. • At room temperature [25°C (77°F)]: Stable for 5 days when stored at room temperature.
