Table of contents:

Ziagen is an antiretroviral medication used in combination with other antiviral medicines to treat patients who are infected with human immunodeficiency virus (HIV), which is the virus that causes acquired immunodeficiency syndrome (AIDS).

Ziagen contains the active ingredient abacavir sulfate and works by decreasing the amount of HIV in the body, allowing the immune system to function better.

While Ziagen can be an effective treatment for HIV, it is not a cure and cannot prevent the transmission of the virus to others. Follow the prescribed regimen exactly as directed and use additional precautions to prevent the spread of HIV.

Use and Dosage

Ziagen is typically taken in tablet form by mouth, with or without food, as directed by a healthcare provider, usually 1 or 2 times daily. Swallow the medication or drink a glass of water right after.

The dosage prescribed will depend on medical condition and response to treatment, with the dosage for children also based on weight. Continue taking Ziagen as prescribed by a healthcare provider, without skipping doses, or increasing the dose or frequency of use without approval from a healthcare provider. Stopping or changing the dose of Ziagen, or other HIV medications, may increase the amount of virus in the body, make the infection more difficult to treat or worsen side effects.

To ensure the medication is effective, it should be taken at evenly spaced times every day. A healthcare provider should be consulted for more detailed instructions on how to take Ziagen safely and effectively.

If a dose is missed, it should be taken as soon as possible, but if it is almost time for the next scheduled dose, the missed dose should be skipped, and the regular dosing schedule should resume. Care should be taken to never double up on doses to make up for a missed dose. Refilling the medication before it runs out is important, and treatment with Ziagen should not be stopped or restarted without consulting with a healthcare provider.
