Important information about some of the ingredients of Modecate
- Sesame oil. This may cause severe allergic (hypersensitivity) reactions.
The chances of this happening are rare. Tell a doctor or nurse straight
away if you get a rash, swallowing or breathing problems and swelling of
your lips, face, throat or tongue.
- Benzyl alcohol. Modecate injection contains 15mg/ml of benzyl alcohol.
It must not be given to premature or newborn babies. Benzyl alcohol
may cause toxic reactions and allergic reactions in infants and children
up to 3 years old.
Recommended dosage regimes for all indications:
Patients without previous exposure to a depot fluphenazine
Initially 0.5ml ie 12.5mg (0.25 ml ie 6.25mg for patients over 60) by deep
intramuscular injection into the gluteal region.
The onset of action generally appears between 24 and 72 hours after
injection and the effects of the drug on psychotic symptoms become
significant within 48 to 96 hours. Subsequent injections and the dosage
interval are determined in accordance with the patient's response. When
administered as maintenance therapy, a single injection may be effective in
controlling schizophrenic symptoms for up to four weeks or longer.
It is desirable to maintain as much flexibility in the dose as possible to
achieve the best therapeutic response with the least side-effects; most
patients are successfully maintained within the dose range 0.5ml (12.5mg)
to 4.0ml (100mg) given at a dose interval of 2 to 5 weeks.
Patients previously maintained on oral fluphenazine
It is not possible to predict the equivalent dose of depot formulation in view
of the wide variability of individual response.
Patients previously maintained on depot fluphenazine
Patients who have suffered a relapse following cessation of depot
fluphenazine therapy may be restarted on the same dose, although the
frequency of injections may need to be increased in the early weeks of
treatment until satisfactory control is obtained.
