Antidepressants Generic Zyprexa Olanzapine 10/20mg

Common Uses

Zyprexa (olanzapine) is what they call an atypical antipsychotic medication. It’s used to treat a variety of mental health conditions, including schizophrenia in adults and kids 13 and older, and bipolar disorder in adults and kids 10 and older. For bipolar disorder, it can be used alone or combined with other medications like fluoxetine or lithium to treat both manic episodes and depressive episodes. There’s also a version of it combined with fluoxetine called Symbyax that’s specifically for bipolar depression and treatment-resistant depression.

The way olanzapine works in your brain is pretty complex. It affects several different neurotransmitters, mainly dopamine and serotonin receptors. By balancing these chemicals, it can help reduce hallucinations and delusions in schizophrenia, calm down the extreme highs of mania, and lift the crushing lows of bipolar depression.

Doctors sometimes prescribe it off-label for other things too, like severe nausea, agitation, or even as a sleep aid in hospital settings. But the main approved uses are for schizophrenia and bipolar disorder.

The most important warnings — please read this

Look, there are some things you absolutely need to know before starting Zyprexa. It comes with serious FDA black box warnings, which is the strongest warning they give.

Increased risk of death in elderly patients with dementia. This is crucial — antipsychotics like Zyprexa can increase the risk of death in older adults with dementia-related psychosis. It’s just not approved for that use. If you’re an older adult with memory problems and psychosis, this isn’t the right medication.

Suicidal thoughts and behaviors. Like many psychiatric meds, antidepressants and antipsychotics can increase the risk of suicidal thinking, especially in children, adolescents, and young adults during the first few months of treatment or when doses change. If you’re in that age group, you and your family need to watch closely for any sudden changes — worsening depression, agitation, panic attacks, trouble sleeping, irritability, or any thoughts about hurting yourself. If something feels off, call your doctor immediately.

Metabolic changes. Zyprexa is known to cause significant weight gain, increased blood sugar (which can lead to diabetes), and increased cholesterol and triglyceride levels. These changes can happen quickly and be substantial. Your doctor should check your weight, blood sugar, and cholesterol before you start and monitor them regularly during treatment.

Before taking Zyprexa

Your doctor needs to know about any medical conditions you have, especially:

• Diabetes or risk factors for diabetes — Zyprexa can raise blood sugar significantly. Watch for increased thirst, peeing more often, feeling very hungry, or weakness.
• High cholesterol or triglycerides — this med can cause increases in blood fats. Regular blood tests are important.
• Heart problems — including a history of heart attack, irregular heartbeat, or heart failure.
• Liver disease — your liver processes this medication, so dose adjustments may be needed.
• Seizures or epilepsy — olanzapine can lower the seizure threshold.
• Enlarged prostate or trouble urinating.
• Glaucoma (especially narrow-angle).
• Bowel obstruction or constipation problems.
• Low white blood cell count.
• Breast cancer — olanzapine can raise prolactin levels, which might matter for certain types of cancer.
• Allergies to any medications.

If you’re pregnant, planning to become pregnant, or breastfeeding — this is a must-discuss. Taking Zyprexa in the third trimester can cause withdrawal symptoms or movement problems in the newborn. It passes into breast milk too, so you need to weigh the risks and benefits with your doctor. There’s a pregnancy registry for atypical antipsychotics you can join.

Drug interactions

Zyprexa reacts with a number of medications. Your doctor needs to know about everything you take — prescriptions, over-the-counter, vitamins, herbs. Careful monitoring may be necessary if you’re taking:

• HIV protease inhibitors like ritonavir — can affect olanzapine levels.
• Haloperidol — another antipsychotic.
• Tramadol — a pain medication.
• Medications that affect the central nervous system — like benzodiazepines (Xanax, Valium), alcohol, sleeping pills, other antipsychotics, antidepressants. These can increase drowsiness and sedation.
• Blood pressure medications — Zyprexa can lower blood pressure, so combining may cause excessive drops.
• Levodopa and dopamine agonists — Zyprexa may block their effects.
• Medications that prolong QT interval — certain antiarrhythmics, antibiotics, antidepressants — because Zyprexa can also affect heart rhythm.
• Carbamazepine — can decrease olanzapine levels.
• Smoking — cigarettes can speed up how fast your body breaks down olanzapine, so smokers may need higher doses.

The interaction of Zyprexa with other medications can cause unnecessary side effects or may make the drug less effective. To avoid problems, immediately inform your physician of all prescription or over-the-counter medications that you’re currently taking. This list isn’t complete, so always check with your pharmacist before adding anything new.

How should I take Zyprexa?

Don’t self-medicate. Follow your doctor’s prescription exactly, especially on how the drug should be administered. Don’t change your dose yourself, and don’t stop without talking to them first.

You can take Zyprexa with or without food. If you have a sensitive stomach or hyperacidity, taking it after meals or with a snack might help. The tablets should be swallowed whole with water. There’s also an orally disintegrating tablet that dissolves on your tongue — for those, keep them in the blister pack until you’re ready to take one, use dry hands to open it, and place it on your tongue right away. It’ll dissolve quickly in your saliva.

Here’s the thing — it can take several weeks to feel the full effect. Don’t give up if you don’t feel different right away. And when you do start feeling better, keep taking it unless your doctor says otherwise. Stopping early is one of the biggest reasons these meds fail.

If you miss a dose, take it as soon as you remember — unless it’s almost time for your next dose. In that case, skip the missed one and get back on your regular schedule. Never double up to catch up. Don’t take your missed dose and the next dose at a very short interval — that can be dangerous.

When it’s time to stop, don’t quit suddenly. Withdrawal symptoms can include insomnia, nausea, vomiting, dizziness, and just feeling awful. Your doctor will help you taper down slowly.

Storage and handling

Store Zyprexa at room temperature, away from direct heat, light, and moisture. Keep it in a tightly closed container. Keep out of reach of kids and pets — an overdose would be dangerous.

The expiration date is printed on each bottle or blister pack. Different batches have different dates, but generally it’s about 2 years from when it was made. Don’t take expired medication — it might not work well.

Possible side effects

Let’s be real about side effects. Everyone wants to know what they’re getting into. Zyprexa has some significant ones you need to know about.

Very common side effects that affect more than 1 in 10 people:

• Weight gain — this can be substantial. Some people gain 10-20 pounds or more, especially in the first few months. Your doctor should monitor your weight regularly.
• Drowsiness or sedation — this is very common, especially when you first start. Taking it at bedtime helps.
• Increased appetite — often goes with the weight gain.
• Dry mouth — keep water handy or try sugarless gum.
• Constipation — increase fiber and fluids.
• Dizziness — especially when you stand up fast.
• Restlessness — feeling like you can’t sit still.

Common side effects:

• Weakness or fatigue.
• Swelling in your hands or feet (fluid retention).
• Increased cholesterol and triglycerides — you might not feel this, but blood tests will show it.
• Increased blood sugar — watch for increased thirst, urination, hunger, or weakness.
• Changes in liver enzymes.
• Tremors or shakiness.

Serious side effects that need immediate medical attention:

• Neuroleptic Malignant Syndrome (NMS) — rare but life-threatening. Symptoms include high fever, severe muscle stiffness, confusion, sweating, fast or uneven heartbeat. Stop the med and get emergency help immediately.
• Tardive dyskinesia — uncontrolled movements of your face, tongue, or other body parts. These can be permanent. Tell your doctor right away if you notice any lip smacking, tongue thrusting, puffing of the cheeks, puckering of the lips, grimacing, twisting or twitching movements, or chewing movements.
• High blood sugar (hyperglycemia) — can lead to diabetic ketoacidosis or coma if not treated. Watch for increased thirst, frequent urination, increased hunger, weakness, or fruity-smelling breath.
• Severe allergic reactions — rash, hives, itching, difficulty breathing, swelling of the face, lips, tongue, or throat.
• Muscle spasms or stiffness — especially of the face, neck, or back, difficulty swallowing, difficulty moving the eyes, stiffness of arms or legs, tremors in hands, tension in legs.
• Prolonged or painful erection (priapism) — seek help immediately if this happens.
• Difficulty swallowing — can lead to choking.
• Seizures.
• Fainting or severe dizziness.
• Vision changes — blurred vision or eye pain.
• Low white blood cell count — signs include fever, sore throat, mouth sores, frequent infections.
• Pancreatitis — severe abdominal pain that may radiate to your back, nausea, vomiting.
• Blood clots — swelling, pain, redness in one leg; sudden chest pain, trouble breathing.

If you notice anything in that serious list, don’t wait around — get medical help right away.

Patients may also experience immediate side effects that usually go away during treatment. But if they persist or bother you, tell your doctor.

Overdose

If someone takes too much Zyprexa, it’s an emergency. Overdose symptoms include:

• Agitation or restlessness.
• Severe drowsiness or sleepiness.
• Heart palpitations or fast heartbeat.
• Difficulty speaking or slurred speech.
• Muscle stiffness.
• Unconsciousness.
• Seizures.
• Delirium or confusion.

Call poison control or get to an emergency room immediately. Bring the pill bottle with you so doctors know what was taken.

Contraindications and precautions

Do not take Zyprexa if you’re allergic to olanzapine or any of its ingredients. If you’ve had an allergic reaction before, tell your doctor.

Since dizziness is a common side effect, be careful while driving or operating machinery until you know how this medication affects you. Avoid quick movements — when getting up from sitting or lying down, rise slowly to give your body time to adjust. Hot weather, fever, and exercise can increase dizziness and also put you at risk for heat stroke. Stay hydrated, avoid overheating, and rest in cool places.

Avoid alcohol completely while on Zyprexa. Alcohol can make the side effects much worse, especially drowsiness and dizziness, and can impair your motor skills and judgment. It’s just not safe to mix them.

Zyprexa may increase your risk of developing diabetes or raise your blood sugar. Your doctor should check your blood sugar before you start and monitor it regularly. If you notice signs of high blood sugar — increased thirst, more frequent urination, increased hunger, vision changes, or weakness — tell your doctor right away.

Regular medical check-ups and blood tests are important while on Zyprexa to monitor your weight, blood sugar, cholesterol, and overall progress. Keep all your appointments.

Pregnancy and breastfeeding

There are no well-controlled studies that confirm the safety of Zyprexa during pregnancy. If you’re pregnant, planning to become pregnant, or breastfeeding, you absolutely must discuss this with your doctor. Some studies suggest that using antipsychotics in the third trimester may cause withdrawal symptoms or movement problems in newborns. It’s not known if olanzapine passes into breast milk, so doctors generally advise against breastfeeding while taking this medication. If taking Zyprexa is the only option, your doctor can help you weigh the risks and benefits and discuss the latest research with you.

Other important information

Never share Zyprexa with others, even if they have similar symptoms. They need their own prescription and medical supervision. Don’t use this medicine for conditions other than what it was prescribed for.

Keep Zyprexa out of reach of children. An overdose could be very dangerous for a child.

What is the shelf life of the pills?

The expiry date is printed on each blister or bottle. It’s different for different batches. The shelf life is typically 2 years from the date of manufacture and can vary from batch to batch. Don’t take expired medication — it might not work as well and could potentially be harmful.
