COMPLETE can be taken alone or in combination with food (see section 5.2). Tamiflu taken with food can increase tolerance in some patients.

EXAMPLES (FOR USE) _ FORMULATIONS WITHOUT TOMATO oral suspension Adults, adolescents or children who can not swallow capsules may take TAMIFLU doses by draining the capsule in a small amount of sweetened food to mask bitter taste, if there is no TAMIFLU oral suspension. section 6.6).

Additional information on special populations:

Renal insufficiency: Used for influenza therapy: Dose adjustment is not necessary for patients with creatinine clearance> 30 mL / min; you can continue to use 75 mg twice a day. In patients with creatinine clearance 10-30 mL / min, it is recommended that the dose be reduced to 75 mg once daily or 30 mg twice daily for 5 days, or to 30 mg capsules twice daily for TAMIFLU. In patients with end-stage renal disease entering routine hemodialysis or continuous peritoneal dialysis, and in patients with creatinine clearance ≤10 mL / min, there is no recommended dose (see section 5.2 and section 4.4).

For influenza prophylaxis: Dose adjustment is not necessary for patients with creatinine clearance> 30 mL / min; 75 mg once a day can be continued to use. Patients receiving TAMIFLU with creatinine clearance 10-30 mL / min are advised to reduce the dose to 75 mg twice daily or alternatively once daily, to 30 mg capsules or 30 mg suspensions. In patients with end-stage renal disease entering routine hemodialysis or continuous peritoneal dialysis, and in patients with creatinine clearance ≤10 mL / min, there is no recommended dose (see section 5.2 and section 4.4).

Clinical data are insufficient to recommend any dose in children with renal insufficiency.

Hepatic insufficiency: For influenza treatment or prophylaxis, dosage adjustment is not necessary for patients with mild to moderate hepatic dysfunction (see section 5.2). Safety and pharmacokinetic properties of patients with severe hepatic insufficiency have not been studied. Pediatric patients with hepatic insufficiency have not been studied.

Pediatric population: In children under 1 year, the safety and efficacy of TAMIFLU has not been established (see section 5.2). COMPLETE can only be used for the treatment of influenza in children under 1 year, provided that it is temporarily used during an epidemic, by a doctor's recommendation or under the supervision of a physician. In all other cases, TOMMY should not be used in children under 1 year of age (see section 5.3).

4

Geriatric population: For influenza treatment or prophylaxis, elderly patients do not require dose adjustment (see section 5.2).

Immune system deprived patients: Up to 12 weeks, longer seasonal prophylaxis has been evaluated in patients with impaired immunosuppression (see sections 4.4, 4.8 and 5.1).

4.3 Contraindications

Oseltamivir is contraindicated in persons who are known to be hypersensitive to any of the ingredients of the phosphate or drug.

4.4 Special warnings and precautions for use

Neuropsychiatric events such as convulsions and delirium have been reported in patients receiving influenza treatment with COMPLETE, especially in children and adolescents. In rare cases, these incidents have caused injury by accident. The contribution of TAMIFLU to these events is unknown. Neuropsychiatric events have also been reported in influenza patients who do not use COMPLETE (see section 4.8).

Patients, especially children and adolescents, should be carefully monitored for abnormal behavior.

There is no evidence that tamiflu is effective in the diseases caused by other agents other than influenza A and B viruses.

The safety and efficacy of oseltamivir therapy or prophylaxis in immunosuppressed patients has not been proven precisely (see section 5.1).

The efficacy of oseltamivirin has not been demonstrated in the treatment of patients with chronic heart failure and / or respiratory disease. There was no difference in the incidence of complications between the treatment and placebo groups in this population (see section 5.1).

Data providing a dose recommendation for premature infants (postmenstrual age * <37 weeks) is not currently available. * Time between the first day of the last normal menstrual cycle and the evaluation day, gestational age plus postnatal age.

It is not used in place of IMPACTED influenza vaccine. Tamiflu is not expected to affect the evaluation of individuals for annual influenza vaccination. Protection against Influenza lasts until TAMIFLU is given. Reliable epidemiologic data can be used in the treatment and prevention of TOTAL influenza if the population shows influenza virus circulation.

Dosage adjustment during influenza treatment and prophylaxis is recommended for patients with creatinine clearance of 10-30 mL / min. There are no recommended doses for patients with end-stage renal disease and patients with creatinine clearance ≤10 mL / min who are on routine hemodialysis and continuous peritoneal dialysis treatment.renal insufficiency

Clinical data are insufficient to recommend any dose in children with(see sections 4.2 and 5.2).

Croscarmellose sodium and sodium stearyl fumarate: This medicinal product contains less than 1 mmol (23 mg) of sodium per dose. No adverse effects due to sodium are expected.

COMPLETE can only be used for the treatment of influenza in children under 1 year (see section 5.3), provided that it is temporarily used during an epidemic, with a doctor's recommendation or under the supervision of a physician.

4.5 Interactions with other medicinal products and other forms of interaction

According to information obtained from pharmacological and pharmacokinetic studies, clinically significant drug interactions with oseltamivir phosphate are unlikely to occur.

Oseltamivir phosphate is largely converted into its active metabolite, mostly by esterases found in the liver. Drug interactions, including competition for esterases, have not been widely reported in the literature. Low binding of oseltamivir and its active metabolite to plasma proteins demonstrates that there is no problem in terms of drug interactions.

In vitro studies have shown that oseltamivir phosphate or active metabolite is not a good substrate for microsomal P450 cytochrome enzymes and glucuronyl transferases (see section 5.2). There is no evidence that it interacts with oral contraceptives.

There is no effect on the plasma levels of cetethidine, oseltamivir, or active metabolite, which is a non-specific inhibitor of cytochrome P450 isoforms and competing for renal tubular secretion of basic or cationic drugs.

Clinically significant drug interactions involving competition for renal tubular secretion are unlikely, depending on the known safety limits of these drugs, the active metabolite elimination characteristics (glomerular filtration and anionic tubular secretion), and the breakthrough capacities of these pathways. Due to the decrease in active tubular secretion in the kidney, the concentration of active metabolite is about 2-fold increased as a result of use with probenecid. However, depending on the wide safety margin of the active metabolite, dose adjustment is not necessary when the renal function is normal during use with probenecid.

Co-administration with amoxicillin does not alter the plasma levels of both compounds due to the weakness of the competitor for anionic secretion pathways.

Use with paracetamol does not affect plasma levels of oseltamivirin, active metabolite, or paracetamol.

When used in combination with paracetamol, acetic salicylic acid, cimetidine or antacids (Magnesium and aluminum hydroxides and calcium carbonates), no pharmacokinetic interaction between oseltamivir or major metabolite is observed.

-receptor blockers (ranitidine, have been applied with commonly used medications such as blockers (propranolol), xanthines (theophylline), sympathomimetics (pseudoephedrine), opioids (codeine), corticosteroids, induction bronchodilators and analgesics (aspirin, ibuprofen and paracetamol). There was no change in the profile or frequency of ending adverse events of administration of tamiflu with these compounds.

Caution should be exercised when administering oseltamivir to patients with the same route of administration and with narrow therapeutic interventions (eg chlorpropamide, methotrexate, phenylbutazone).

special populations No interaction studies have been done on specific populations.

Pediatric population: No interaction studies of the pediatric population have been conducted.

4.6 Pregnancy and lactation

General advice Pregnancy category: C

Women with childbearing potential / Birth control (Contraception) There is no recommendation for the use of medication in women with childbearing potential and contraception.

Pregnancy period Although pregnant women using oseltamivir have not undergone controlled studies, there are limited data from post-marketing and retrospective observational follow-up reports. These data, together with studies conducted on animals, do not indicate that they are directly or indirectly harmful in relation to pregnancy / embryonal / fetal development / birth or postnatal development (see section 5.3). Given current safety data, the pathogenicity of circulating influenza virus strain and the underlying condition of the pregnant woman, TAMIFLU can be used in pregnant women. TAMIFLU should not be used in pregnant women unless the potential benefit to the patient is greater than the potential risk to the fetus.

Lactation The studies on animals show that oseltamivir is poured into the milk. There is very limited data as to whether oseltamivir is excreted in human milk. This limited data shows that oseltamivir and its active metabolite are detected in the mother's milk. However, the levels set in the milk are very low and therefore the baby will receive an amount under the therapeutic dose. When deciding whether or not to stop breastfeeding or stopping TAMIFLU treatment, it is important to consider the pathogenicity of circulating influenza virus strains, the benefit of breastfeeding for the child, and the benefit of TAMIFLU treatment for breastfeeding mothers.

Reproductive ability / Fertility In nonclinical studies, reproductive performance, fertility and sperm evaluation parameters were not affected when given TAMIFLU. Nonclinical studies based on reproductive toxicity studies do not present a potential risk to humans.

4.7 Effects on

vehicle and machine use TAMIFLU has no effect on vehicle and machine use.

4.8 Undesirable effects The

safety profile of TAMIFLU is based on the data of 2107 adult and 1032 pediatric patients receiving TAMIFLU for influenza treatment in clinical trials and 2914 adult and 148 pediatric patients receiving TAMIFLU or placebo for influenza prophylaxis.

In adults, the most commonly reported adverse effects are vomiting and nausea in treatment trials, nausea and headache in prevention trials. The majority of these adverse events were reported on the first or second day of treatment upon first dose use and spontaneously resolved within 1-2 days. In children, the most commonly reported adverse reaction is vomiting.

Adverse drug reactions are listed according to the frequency defined below: Very common (≥1 / 10); diffuse (≥1 / 100 to <1/10), non-diffuse (≥1 / 1.000 to <1/100); rare (≥1 / 10,000 to <1 / 1,000); very rare (<1 / 10,000), unknown (can not be estimated from the given data). Adverse events were added to the appropriate categories in the charts according to pooled analyzes from clinical trials. In each frequency group, adverse effects were listed in descending order of severity.
