Odystra 23 mg) FC tablets

ODYSTRA is indicated for the treatment of HIV-1 infection in adults aged 18 years and older.

Posology Therapy should be initiated by a doctor experienced in the management of HIV infection.

Adults: The dose of ODYSTRA is one tablet taken orally, once daily, without regard to food.

Special Populations

Paediatrics: ODYSTRA is not recommended for use in patients younger than 18 years of age.

Dose adjustment for renal impairment: Significantly increased exposure occurred when tenofovir, as in ODYSTRA, was administered to patients with moderate to severe renal impairment (see section 4.3 Contraindications). The pharmacokinetics of tenofovir, as in ODYSTRA, have not been evaluated in non-haemodialysis patients with creatinine clearance < 50 ml/min); therefore, no dosing recommendations is available for these patients. ODYSTRA is not suitable for use in patients with renal impairment with creatinine clearance less than 50 ml/min. Rifampicin decreases the blood levels of dolutegravir. A supplementary dose of dolutegravir should be given to patients taking ODYSTRA.

• ODYSTRA tablets are contraindicated in patients with known hypersensitivity to lamivudine, tenofovir or dolutegravir or to any of the components of the tablets.
• Uncontrolled renal failure (see section 4.4 Special warnings and precautions for use).
• Pregnancy and lactation (see section 4.6 Fertility, pregnancy and lactation).
• Women of child-bearing age not using highly effective contraception.
• Concomitant use with adefovir dipivoxil.
• Co-administration with dofetilide and pilsicainide.
• Co-administration with didanosine.
• Patients younger than 18 years of age.
• Moderate and severe hepatic impairment.

Safety and efficacy of the individual active ingredients in various antiretroviral combination regimens with similar dosages as contained in ODYSTRA have been established in clinical studies for the treatment of HIV patients. However, safety and efficacy of the fixed drug combination as in ODYSTRA for the treatment of HIV have not been established in clinical studies.

Depression (including suicidal ideation): ODYSTRA can cause depression and suicidal ideation behaviour, particularly in patients with a pre-existing history of depression or psychiatric illness. Patients should inform their doctor if they notice any symptoms of depression during treatment.

The complete package inserts of the other medicines used in combination should be consulted before initiation of therapy.

Metabolic abnormalities: Combination antiretroviral therapy, including ODYSTRA has been associated with metabolic abnormalities such as hypertriglyceridaemia, hypercholesterolaemia, insulin resistance, hyperglycaemia and hyperlactataemia.

Patients receiving ODYSTRA may continue to develop opportunistic infections and other complications of HIV infection, and therefore should remain under close clinical observation by doctors experienced in the treatment of patients with HIV associated diseases.

The risk of HIV transmission to others: Patients must be advised that treatment with antiretroviral ODYSTRA, have not been proven to prevent the risk of transmission of HIV to others through sexual contact or blood contamination. Appropriate precautions must continue to be used.

Lactic acidosis/severe hepatomegaly with steatosis: Lactic acidosis, usually associated with hepatic steatosis, including fatal cases, has been reported with the use of nucleoside analogues, such as in ODYSTRA. Early symptoms (symptomatic hyperlactataemia) include benign digestive symptoms (nausea, vomiting and abdominal pain), non-specific malaise, loss of appetite, weight loss, respiratory symptoms (rapid and/or deep breathing) or neurological symptoms (including motor weakness). Lactic acidosis has a high mortality and may be associated with pancreatitis, liver failure or renal failure.

The likelihood of interactions is low due to the limited metabolism as plasma protein binding and almost complete renal clearance. Zidovudine plasma levels are not significantly altered when co-administered with Lamivudine. Zidovudine has no effect on the pharmacokinetics of lamivudine. Lamivudine may inhibit the intracellular phosphorylation of zalcitabine when the two medicinal products are used concurrently. Lamivudine is therefore not recommended to be used in combination with zalcitabine.

...

Women of childbearing potential / Contraception in males and females ODYSTRA should not be prescribed in women who plan to become pregnant. Woman of child-bearing age should not use ODYSTRA unless they are reliably using highly effective contraception. Treatment with ODYSTRA should not be initiated without a medically supervised negative pregnancy test. This test should be repeated at frequent intervals during treatment with ODYSTRA; and especially in the event that pregnancy is suspected.

...

ODYSTRA may affect the ability to drive and use machines. Patients should ensure that they do not engage in driving or using machines until they know how ODYSTRA affects them.

ODYSTRA can have side effects. Psychiatric disorders: Less frequent: depression. The following side effects have been reported during therapy for HIV disease with ODYSTRA tablets alone and in combination with other antiretrovirals.

...

Tenofovir disoproxil fumarate: If overdose occurs the patient must be monitored for evidence of toxicity and palliative supportive treatment be applied as necessary. Tenofovir can be removed by haemodialysis; the median haemodialysis clearance of tenofovir is 134 ml/min. The elimination of tenofovir by peritoneal dialysis has not been studied.
