Trilafon decanoate – Decanoate uses, dose and side effects


108 mg/ml solution for injection perphenazine

What Trilafon decanoate is and what it is used for

Trilafon decanoate belongs to a group of medicines used in the treatment of psychoses.

Trilafon decanoate blocks certain signaling substances in the central nervous system and thereby acts with a pronounced antipsychotic effect (reduces delusions, delusions, disturbance in thought process, confusion, and disturbance of consciousness) and also acts to suppress psychomotor restlessness (psychologically conditioned movement patterns).

Trilafon decanoate is used for delusions, leaps in thought, disturbance of consciousness, lack of understanding of illness, hallucinations (delusions), with several symptoms of mental illness.

Perphenazine decanoate contained in Trilafon decanoate may also be approved to treat other conditions not mentioned in this leaflet. Ask your doctor, pharmacist or other healthcare professional if you have any further questions and always follow their instructions.

Trilafon decanoate passes into breast milk but is unlikely to affect children who are breastfed.

Driving ability and use of machinery

Trilafon decanoate can impair the ability to react in some people, which should be taken into account at times when increased attention is required, for example when driving a car and working with precision.

You yourself are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires increased attention. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and/or side effects . Description of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. Discuss with your doctor or pharmacist if you are unsure.

Trilafon decanoate contains propyl paraben and sesame oil

In rare cases, sesame oil can cause a severe allergic reaction .

  • experience allergic reaction with skin reaction, facial swelling and/or fever. Contact a doctor immediately if swelling of e.g. face, tongue and/or throat and/or difficulty swallowing or hives occurring together with difficulty breathing occurs ( angioedema ).
