Why are peak and trough levels drawn?

The lowest level of the drug in the patient’s body is called the trough level. The peak for a drug is when the level of the drug in the patient’s body is the highest. To assess drug concentrations during the trough phase, blood should be drawn immediately before the next dose.

How do you determine peak and trough levels?

To assess drug concentrations during the trough phase, blood should be drawn immediately before the next dose. To assess peak levels, the time for drawing depends on the route of administration: Oral: One hour after drug is taken (assumes a half-life of > two hours) IV: 15-30 minutes after injection/infusion.

When do you draw a Vanco trough?

Why are trough levels important?

To adequately evaluate the appropriate dosage levels of many drugs, the collection and testing of specimens for trough and peak levels is necessary. The trough level is the lowest concentration in the patient’s bloodstream, therefore, the specimen should be collected just prior to administration of the drug.

• bitter taste.
• reddish rash on face and upper body (intravenously: red neck or red man syndrome, related to infusion rate)
• low blood pressure accompanied by flushing.
• nausea.
• vomiting.
• chills.
• drug fever.
• high levels of white blood cells (eosinophilia)

How long can you stay on vancomycin?

The usual dose is 40 milligrams per kilogram (mg/kg) of body weight, divided into 3 or 4 doses, and taken for 7 to 10 days. However, dose is usually not more than 2000 mg per day.
