Posology In mono- and adjunctive therapy, treatment with Oxcarbazepine Morningside Tablets is initiated with a clinically effective dose given in two divided doses. The dose may be increased depending on the clinical response of the patient.
When other antiepileptic medicinal products are replaced by Oxcarbazepine Morningside Tablets, the dose of the concomitant antiepileptic medicinal product(s) should be reduced gradually on initiation of Oxcarbazepine Morningside Tablets therapy.
5). Therapeutic drug monitoring The therapeutic effect of oxcarbazepine is primarily exerted through the active metabolite 10-monohydroxy derivative (MHD) of oxcarbazepine (see section 5). Plasma level monitoring of oxcarbazepine or MHD is not routinely warranted.
4). In such situations, the dose of Oxcarbazepine Morningside Tablets may be adjusted (based on plasma levels measured 2-4 hours post dose) to maintain peak MHD plasma levels < 35 mg/L. Adults Monotherapy Recommended initial dose Oxcarbazepine Morningside Tablets should be initiated with a dose of 600 mg/day (8-10 mg/kg/day) given in 2 divided doses.
Maintenance dose If clinically indicated, the dose may be increased by a maximum of 600 mg/day at approximately weekly intervals from the starting dose to achieve the desired clinical response. Therapeutic effects are seen at doses between 600 mg/day and 2,400 mg/day.
Controlled monotherapy trials in patients not currently being treated with antiepileptic medicinal products showed 1,200 mg/day to be an effective dose; however, a dose of 2400 mg/day has been shown to be effective in more refractory patients converted from other antiepileptic medicinal products to oxcarbazepine monotherapy.
Maximum recommended dose In a controlled hospital setting, dose increases up to 2,400 mg/day have been achieved over 48 hours. Adjunctive therapy Recommended initial dose Oxcarbazepine Morningside Tablets should be initiated with a dose of 600 mg/day (8-10 mg/kg/day) given in 2 divided doses.
Maintenance dose If clinically indicated, the dose may be increased by a maximum of 600 mg/day at approximately weekly intervals from the starting dose to achieve the desired clinical response. Therapeutic responses are seen at doses between 600 mg/day and 2,400 mg/day.
Summary of the safety profile The most commonly reported adverse reactions are somnolence, headache, dizziness, diplopia, nausea, vomiting and fatigue occurring in more than 10% of patients. The safety profile is based on AEs from clinical trials assessed as related to oxcarbazepine.
In addition, clinically meaningful reports on adverse experiences from named patient programs and postmarketing experience were taken into account. Adverse reactions (Table 1) are listed by MedRA system organ class. Within each system organ class, the adverse reactions are ranked by frequency, with the most frequent first.
Within each frequency grouping, adverse reactions are presented in order of decreasing seriousness. In addition, the corresponding frequency category, using the following convention (CIOMS III) is also provided for each adverse reaction: - very common: ≥ 1/10; - common: ≥ 1/100 - < 1/10; - uncommon: ≥ 1/1,000 - < 1 /100; - rare: ≥ 1/10,000 - < 1/1,000; - very rare: < 1/10,000; Table 1 Adverse reactions Blood and lymphatic system disorders Uncommon leucopoenia.
Very rare thrombocytopenia. Rare bone marrow depression, aplastic anaemia, agranulocytosis, pancytopaenia, neutropenia. Immune system disorders Very rare hypersensitivity#. Rare anaphylactic reactions. Endocrine disorders Common Weight increased Uncommon hypothyroidism.
Metabolism and nutrition disorders Common hyponatraemia*. Rare Inappropriate ADH secretion like syndrome with signs and symptoms of lethargy, nausea, dizziness, decrease in serum (blood) osmolality, vomiting, headache, confusional state or other neurological signs and symptoms.
g. nervousness), affect lability, confusional state, depression, apathy. Nervous system disorders Very common somnolence, headache, dizziness. Common ataxia, tremor, nystagmus, disturbance in attention, amnesia,Speech disorders (including dysarthria); more frequent during up titration of oxcarbazepine dose.
Hypersensitivity Class I (immediate) hypersensitivity reactions including rash, pruritus, urticaria, angioedema and reports of anaphylaxis have been received in the post-marketing period. Cases of anaphylaxis and angioedema involving the larynx, glottis, lips and eyelids have been reported in patients after taking the first or subsequent doses of oxcarbazepine.
If a patient develops these reactions after treatment with oxcarbazepine, the drug should be discontinued and an alternative treatment started. g. 8). Hypersensitivity reactions, including multi-organ hypersensitivity reactions, may also occur in patients without a history of hypersensitivity to carbamazepine.
8). In general, if signs and symptoms suggestive of hypersensitivity reactions occur, oxcarbazepine should be withdrawn immediately. Dermatological effects Serious dermatological reactions, including Stevens-Johnson syndrome, toxic epidermal necrolysis (Lyell's syndrome) and erythaema multiforme, have been reported very rarely in association with the use of oxcarbazepine.
Patients with serious dermatological reactions may require hospitalization, as these conditions may be life-threatening and very rarely be fatal. Oxcarbazepine associated cases occurred in both children and adults. The median time to onset was 19 days.
Several isolated cases of recurrence of the serious skin reaction when rechallenged with oxcarbazepine were reported. Patients who develop a skin reaction with Oxcarbazepine Morningside Tablets should be promptly evaluated and oxcarbazepine withdrawn immediately unless the rash is clearly not drug related.
In case of treatment withdrawal, consideration should be given to replacing oxcarbazepine with other antiepileptic drug therapy to avoid withdrawal seizures. 3). HLA-B*1502 allele – in Han Chinese, Thai and other Asian populations HLA-B*1502 in individuals of Han Chinese and Thai origin has been shown to be strongly associated with the risk of developing the severe cutaneous reactions known as Stevens-Johnson syndrome (SJS)/ toxic epidermal necrolysis (TEN) when treated with carbamazepine.

Maximum recommended dose Daily doses from 600 to 2,400 mg/day have been shown to be effective in a controlled adjunctive therapy trial, although most patients were not able to tolerate the 2,400 mg/day dose without reduction of concomitant antiepileptic medicinal products, mainly because of CNS-related adverse events.
Daily doses above 2,400 mg/day have not been studied systematically in clinical trials. Elderly (65 years old and above) No special dose recommendations are necessary in elderly patients because therapeutic doses are individually adjusted.
Dosage adjustments are recommended in elderly patients with renal impairment (creatinine clearance less than 30 ml/min) (see information below on “dosage in renal impairment”). 4). Patients with hepatic impairment No dosage adjustment is required for patients with mild to moderate hepatic impairment.
2). 2). Dose escalation in renally impaired patients may require more careful observation. Paediatric population Recommended initial dose In mono- and adjunctive therapy, Oxcarbazepine Morningside Tablets should be initiated with a dose of 8-10 mg/kg/day given in 2 divided doses.
Maintenance dose In adjunctive therapy trials, a maintenance dose of 30-46 mg/kg/day, achieved over two weeks, is shown to be effective and well tolerated in children. Therapeutic effects were seen at a median maintenance dose of approximately 30 mg/kg/day.
2). This medicine is recommended for use in children of 6 years of age and above. Safety and efficacy have been evaluated in controlled clinical trials involving approximately 230 children aged less than 6 years (down to 1 month). Oxcarbazepine is not recommended in children aged less than 6 years since safety and efficacy have not been adequately demonstrated.
All the above dosing recommendations (adults, elderly and children) are based on the doses studied in clinical trials for all age groups. However, lower initiation doses may be considered where appropriate. Method of administration The tablets are scored and can be broken in two halves in order to make it easier for the patient to swallow the tablet.
However, the tablet cannot be divided into equal doses. For children, who cannot swallow tablets or where the required dose cannot be administered using tablets, Oxcarbazepine oral suspension is available. This medicine can be taken with or without food.

The chemical structure of oxcarbazepine is similar to that of carbamazepine, and it is possible that patients who are positive for HLAB*1502 may also be at risk for SJS/ TEN after treatment with oxcarbazepine. There are some data that suggest that such an association exists for oxcarbazepine.
The prevalence of HLA-B*1502 carrier is about 10% in Han Chinese and Thai populations. Whenever possible, these individuals should be screened for this allele before starting treatment with carbamazepine or a chemically related active substance.
If patients of these origins are tested positive for HLA-B*1502 allele, the use of oxcarbazepine may be considered if the benefits are thought to exceed risks. g. above 15% in the Philippines and Malaysia), testing genetically at risk populations for the presence of HLAB*1502 may be considered.
g. European descent, African, Hispanic populations sampled, and in Japanese and Koreans (< 1%). Allele frequencies refer to the percentage of chromosomes in the population that carry a given allele. Since a person carries two copies of each chromosome, but even one copy of the HLA-B*1502 allele may be enough to increase the risk of SJS, the percentage of patients who may be at risk is nearly twice the allele frequency.
HLA-A*3101 allele – European descent and Japanese populations There are some data that suggest HLA-A*3101 is associated with an increased risk of carbamazepine induced cutaneous adverse drug reactions including SJS, TEN, Drug rash with eosinophilia (DRESS), or less severe acute generalized exanthematous pustulosis (AGEP) and maculopapular rash in people of European descent and the Japanese.
The frequency of the HLA-A*3101 allele varies widely between ethnic populations. HLAA*3101 allele has a prevalence of 2 to 5% in European populations and about 10% in Japanese population. 8%. HLA-A*3101 allele – Other descents The frequency of this allele is estimated to be less than 5% in the majority of Australian, Asian, African and North American populations with some exceptions within 5 to 12%.
Frequency above 15% has been estimated in some ethnic groups in South America (Argentina and Brazil), North America (US Navajo and Sioux, and Mexico Sonora Seri) and Southern India (Tamil Nadu) and between 10% to 15% in other native ethnicities in these same regions.
Allele frequencies refer to the percentage of chromosomes in the population that carry a given allele. Since a person carries two copies of each chromosome, but even one copy of the HLAA*3101 allele may be enough to increase the risk of SJS, the percentage of patients who may be at risk is nearly twice the allele frequency.
There are insufficient data supporting a recommendation for HLA-A*3101 screening before starting carbamazepine or chemically-related compounds treatment. If patients of European descent or Japanese origin are known to be positive for HLA-A*3101 allele, the use of carbamazepine or chemically-related […]
