Zyprexa (Olanzapine): What You Need to Know Right Now

Here’s a blunt fact: Zyprexa can help stabilize mood and psychosis but often causes big weight gain and metabolic changes. If you or someone you care for is starting Zyprexa, knowing the trade-offs helps you spot problems early and get the most benefit.

How Zyprexa affects your body

Zyprexa is an antipsychotic (generic name: olanzapine). It works by blocking certain dopamine and serotonin receptors in the brain, which calms hallucinations, delusions, and extreme mood swings. Doctors commonly prescribe it for schizophrenia and bipolar disorder; sometimes it’s used off-label for severe anxiety or agitation.

Side effects to watch: sedation, dry mouth, constipation, dizziness, and most importantly weight gain, high blood sugar, and raised cholesterol. These metabolic effects can show up in weeks to months. Less common but serious problems include movement issues, severe fever and stiffness (rare: neuroleptic malignant syndrome), and increased risk of death in older adults with dementia-related psychosis.

Practical dosing and safety tips

Typical starting doses for adults are 5–10 mg once daily. Doctors may adjust the dose up to 20 mg depending on response and side effects. Many people take Zyprexa at night because it can make you sleepy. There’s a regular tablet, an orally disintegrating tablet, and a long-acting injectable (Relprevv) for patients who need steady levels.

Before you start: get baseline weight, fasting glucose, and lipid tests. Repeat these checks at 3 months and then periodically. If you smoke, know that smoking lowers olanzapine levels (smoking cessation can raise levels and increase side effects). Certain drugs like fluvoxamine increase olanzapine levels — tell your clinician about all meds and supplements.

If you miss a dose, take it as soon as you remember the same day. Don’t double up doses. Don’t stop Zyprexa suddenly without medical advice — abrupt stopping can cause withdrawal symptoms and risk relapse of psychosis or mood episodes.

Call your doctor or seek urgent care if you get sudden high fever, confusion, very stiff muscles, trouble breathing, fainting, new chest pain, or signs of high blood sugar (extreme thirst, frequent urination, nausea). If you gain a lot of weight quickly or lab tests show big changes in glucose or lipids, ask about switching meds or adding lifestyle and medical steps to protect your health.

Zyprexa helps many people, but it’s not one-size-fits-all. Share questions and side effects with your prescriber, track weight and food intake, and aim for regular blood tests. With the right checks and open communication, you can get benefits while keeping risks under control.

The role of cycloserine in multidrug-resistant tuberculosis management

In my latest blog post, I discussed the crucial role of cycloserine in managing multidrug-resistant tuberculosis (MDR-TB). Cycloserine, an antibiotic, has become increasingly important in the treatment of MDR-TB, especially when other first-line medications are ineffective. This is because it targets the bacteria causing TB in a different way, thus overcoming resistance. However, it's essential to use cycloserine in combination with other antibiotics to ensure maximum effectiveness and minimize the risk of further resistance. Overall, cycloserine plays a vital role in the fight against MDR-TB, and ongoing research is crucial to optimize its use and develop new treatments.

Griseofulvin is a go-to treatment for fungal infections in our furry friends, cats and dogs. It's particularly effective against infections caused by dermatophytes, which affect the skin, hair, and nails. Administered orally, it's absorbed through the pet's digestive tract and then binds to keratin cells, preventing the fungus from infecting new cells. However, it's important to note that Griseofulvin should be used with caution as it can cause side effects such as vomiting, diarrhoea or even blood disorders.
