then injected into muscle of your buttock or thigh.

often to give it. The medicine is slowly released from the injection site so that
a fairly constant amount of medicine gets into your blood during the period
between each dose.
The usual dose lies between 200-500 mg every 1 to 4 weeks but some
patients require 600 mg every week. The maximum single dose at any one
time is 600 mg. If you need more than 2 ml of medicine it will probably be
divided between 2 injection sites.
If you haven’t received an injection like Zuclopenthixol Decanoate before, a
small dose of 100 mg is usually given one week before your normal dose to
