To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Olanzapine extended-release injection is designed to release medication slowly over 2 to 4 weeks. If the medication releases too quickly, your drug levels may be too high. Seek immediate medical attention if any of these symptoms of high olanzapine levels occur: very drowsy/hard to wake up, severe dizziness, slowed breathing, new or worsening mental/mood changes (such as confusion, agitation, nervousness, aggression), restlessness, muscle stiffness/spasm, shaking (tremor), unusual weakness, difficulty walking or speaking, balance problems, seizure.
This drug may rarely make your blood sugar level rise, which can cause or worsen diabetes. Weight gain from this drug may increase the risk of this side effect. Tell your doctor immediately if you develop symptoms of high blood sugar such as increased thirst and urination, breath smells fruity, feel very hungry/weak/tired. If you already have diabetes, be sure to check your blood sugar level regularly.
This drug may cause significant weight gain and a rise in your blood cholesterol (or triglyceride) levels, especially in teenagers. These effects, along with diabetes, may increase your risk for developing heart disease. Discuss the risks and benefits of treatment with your doctor. (See also Notes section.)
Tell your doctor immediately if any of these unlikely but serious side effects occur: yellowing of the eyes/skin, severe abdominal pain, difficulty swallowing, signs of infection (such as fever, persistent sore throat), trouble urinating.
This medication may rarely cause a very serious condition called neuroleptic malignant syndrome (NMS). Get medical help right away if you have any of the following symptoms: fever, muscle stiffness/pain/tenderness/weakness, severe tiredness, severe confusion, sweating, fast/irregular heartbeat, dark urine, change in the amount of urine.
Olanzapine may rarely cause a condition known as tardive dyskinesia. In some cases, this condition may be permanent. Tell your doctor immediately if you develop any unusual/uncontrolled movements (especially of the face or tongue).
In rare cases, olanzapine may increase your level of a certain substance made by the body (prolactin). For females, this increase in prolactin may result in unwanted breast milk, missed/stopped periods, or difficulty becoming pregnant. For males, it may result in decreased sexual ability, inability to produce sperm, or enlarged breasts. If you develop any of these symptoms, tell your doctor immediately.
A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
