4.8 Undesirable effects After intramuscular administration of Glutathione, rare instances of skin rash have been reported which have disappeared after discontinuation of treatment
Stereological analysis of striatum and SNcVTA regions Brains in OCT blocks from animals ( n = 3, male and female paired) at different adult ages from each group (unless stated otherwise) were sectioned coronally at 30 m with Cryostat CM3030 S (Leica Biosystems)
Started with 0.25 mg once daily, injecting subcutaneously about two inches from where the pain was worst
