Table of contents:

Viracept is an oral medication used in the treatment of HIV (Human Immunodeficiency Virus) infection. It contains active ingriedent called Nelfinavir mesylate. Nelfinavir mesylate belongs to the class of drugs known as protease inhibitors, which work by blocking an enzyme that the virus needs to replicate itself.

Viracept is always used in combination with other antiretroviral drugs. It is indicated in antiretroviral combination treatment of human-immunodeficiency-virus (HIV-1)-infected adults, adolescents, and children of three years. Viracept is a prescription medication that should only be taken under the guidance of a healthcare professional.

Use and Dosage

Viracept comes as a tablet that should be taken orally with a meal, as per the directions provided by your doctor. You should take Viracept 2-3 times a day, as instructed, unless your healthcare professional has advised otherwise.

In case you are not able to swallow the tablet, you can crush the dose and take it with food or dissolve it in a small amount of water. However, do not mix it with acidic food or juices like apple juice/sauce and orange juice, as this may make the medication taste bitter. After dissolving Viracept in water, stir the mixture well and drink the whole solution immediately. Rinse your container with additional water and consume the rinse liquid to ensure you receive the complete dose.

Continue taking Viracept, along with other prescribed HIV medications, as directed by your doctor. Do not change your dosage or skip taking Viracept (or other HIV medicines) unless your doctor tells you to. Failing to adhere to the prescribed dose schedule may increase the amount of the virus and make the infection harder to treat or worsen Viracept's side effects.
