ZypAdhera® (olanzapinpamoat): Information om administrering och försiktighetsåtgärder efter injektion.

Olanzapinpamoat är endast avsett för djup intramuskulär gluteal injektion. Administrera inte intravenöst eller subkutant.

Administration and post injection precautions

After insertion of the needle, aspirate for several seconds to ensure no blood appears. If any blood is drawn into the syringe, discard the syringe and the dose and begin reconstitution and administration procedure again.
The injection should be performed with steady, continuous pressure. Do not massage the injection site.1

If blood was visible, the new reconstituted dose should be injected into the alternate buttock, deep into the gluteal muscle.2 

The ventrogluteal site is preferred for IM injections to decrease risk of accessing the sciatic nerve or major blood vessel. Administration at this site also maximizes the likelihood of achieving an IM injection, as opposed to an accidental subcutaneous injection.3,4

It is important to note that proper injection technique does not guarantee that a blood vessel injury has not occurred during the injection.2

Further information from label

Olanzapine pamoate should only be administered by deep intramuscular gluteal injection by a healthcare professional trained in the appropriate injection technique and in locations where post-injection observation and access to appropriate medical care in the case of overdose can be assured.1

After each injection, patients should be observed in a health care facility by appropriately qualified personnel for at least 3 hours for signs and symptoms consistent with olanzapine overdose.1

Immediately prior to leaving the health care facility, it should be confirmed that the patient is alert, oriented, and absent of any signs and symptoms of overdose.1

If an overdose is suspected, close medical supervision and monitoring should continue until examination indicates that signs and symptoms have resolved.1

The 3-hour observation period should be extended as clinically appropriate for patients who exhibit any signs or symptoms consistent with olanzapine overdose.1
