Second, he can take Fluphenazine 1 mg half a tablet before breakfast for 5 days, then half a tablet twice per day before meals for 5 days then increase the dose by half a tablet before meals every 5 days until the dose becomes 1.5 mg twice per day before meals. The anti-oxidant such as Ubiquitous 30 mg before dinner once per day can slow the deterioration of the disease. Hope I have answered your query. Let me know if I can assist you further.
