Myser 250mg Capsule (CYCLOSERINE)

What is Myser capsule?

Myser capsule is an antibiotic that fights many types of bacteria. It's taken by mouth and works quickly, reaching its highest level in the blood within 4-8 hours. A typical dose is 250 milligrams twice a day, keeping the medicine's level in the blood at a safe amount. People with kidney problems may need a different dose. Taking too much (over 500 milligrams daily) can cause nervous system problems. *Antibiotic* means a medicine that kills bacteria. *mcg/mL* stands for micrograms per milliliter, a way to measure how much medicine is in a certain amount of blood.

What is the usual dose of Myser capsule?

• Adults: The typical dosage is 500 mg to 1 g daily, divided into two doses, with an initial dose of 250 mg twice daily for the first two weeks 1.
• Children: Safety and effectiveness in pediatric patients have not been established; therefore, specific dosing guidelines are not provided.

How do I take Myser capsule?

Myser capsule should be taken orally, typically with or without food, but it is advisable to maintain consistency in how it is taken. Patients should avoid alcohol during treatment as it can increase the risk of side effects 

For how long do I take Myser capsule?

The duration of Myser capsule treatment varies based on the condition being treated but typically continues until the infection is resolved, often requiring several months of therapy 

What disease or symptom is Myser capsule used for?

Myser capsule is an antibiotic used to fight tuberculosis (TB), a serious lung infection. It's only used when other TB medications (streptomycin, isoniazid, rifampin, and ethambutol) aren't working well enough, and the TB bacteria are susceptible (meaning the medicine will affect them). Tuberculosis can also affect other parts of the body, like the kidneys (renal disease), and Myser capsule can treat that too. It can also treat some urinary tract infections (UTIs) caused by certain bacteria. However, it's crucial to understand that Myser capsule is *always* used with other antibiotics, never on its own. Using it alone is ineffective and potentially dangerous. Gram-positive and gram-negative refer to the type of bacteria; Myser capsule works against some types of both.

How long does it take for Myser capsule to start working?

Myser capsule reaches peak blood levels within 4 to 8 hours after oral administration, but the time it takes to see clinical improvement can vary depending on the infection and individual patient response

Is Myser capsule effective?

Myser capsule is an antibiotic that fights bacteria by stopping them from building their cell walls. This makes it effective against many types of bacteria, including those that cause tuberculosis (TB), a serious lung infection. "Gram-positive" and "gram-negative" refer to different types of bacteria's cell wall structure; Myser capsule works against both. "In vitro" means in a lab setting, while "clinically" means in real patients. Although Myser capsule works well against TB in both lab tests and real-world treatment, it's crucial to use it *with* other TB medications. Using it alone isn't effective enough and can lead to the bacteria developing resistance (becoming immune to the drug). Therefore, Myser capsule is always part of a combination therapy for TB.

How do I know if Myser capsule is working?

Myser capsule's effectiveness is monitored by blood tests, especially for people with kidney problems, those taking high doses (over 500mg daily), or showing side effects. Weekly tests keep levels below 30 mcg/mL (micrograms per milliliter, a measure of drug concentration in the blood). Older adults need careful dosing because their kidneys might not work as well. Pregnant women should carefully weigh the drug's benefits against potential harm to the baby. Essentially, doctors need to closely watch how much Myser capsule is in the blood to make sure it's helping without harming the patient. Kidney problems (renal function) affect how the body processes the drug.

How does Myser capsule work?

Myser capsule fights bacterial infections by stopping bacteria from building their protective walls. This works against some types of bacteria (gram-positive and gram-negative). After you take it by mouth, it's quickly absorbed into your bloodstream, reaching its highest level in 4-8 hours. Most of it (about 65%) leaves your body through your urine within 3 days, with the most leaving in the first 2-6 hours. Half is gone within 12 hours. The rest is changed into other substances we don't fully understand yet. Gram-positive and gram-negative refer to different types of bacteria based on their cell wall structure.

Who should avoid taking Myser capsule?

Myser capsule is a medicine with several precautions. Don't take it if you're allergic, have epilepsy (seizures), serious mental health issues (anxiety or psychosis), poor kidney function, or drink too much alcohol. If you develop a skin rash (allergic dermatitis), or nervous system problems (like seizures, feeling confused or depressed, sleepiness, tremors, dizziness, muscle weakness, slurred speech, or muscle spasms – all signs of CNS toxicity), stop or reduce your dose immediately. High levels of Myser capsule in your blood can cause toxicity. This is more likely with high doses or if your kidneys aren't working well. Older people, whose kidneys often don't work as well, need their dose carefully adjusted and their kidney function checked regularly.
