What is Emtriva?Emtriva is a medicine used in combination with other medicines to treat HIV (human immunodeficiency virus) infection (AIDS). Emtriva is a type of medication called a nucleoside reverse transcriptase inhibitor (NRTI); it works by lowering the amount of HIV in your blood. Emtriva is available in capsules and an oral solution.
What is the most important information I should know about Emtriva?You must take Emtriva with other HIV medications. Always stay on continuous HIV therapy to control your HIV infection and decrease HIV-related illnesses. Though Emtriva can slow the progress of HIV, it is not a cure. Also, Emtriva does not lower your chance of passing HIV to others through sexual contact with any body fluids, such as semen, vaginal secretions, or blood. You may continue to develop infections and other complications associated with HIV.
Emtriva can cause a rare but serious condition called lactic acidosis (a build-up of an acid in the blood). Tell your doctor immediately if you feel very weak or tired; have unusual muscle pain, trouble breathing, or stomach pain with nausea and vomiting; feel cold, especially in your arms and legs; feel dizzy or lightheaded; or have a fast or irregular heartbeat.
Emtriva can cause serious liver problems with liver enlargement and fat in the liver. Tell your doctor immediately if you experience yellowing of your skin or whites of your eyes, dark urine, light-colored stools, loss of appetite, nausea, or lower abdominal pain.
You have a higher chance of getting lactic acidosis or liver problems if you are a woman, are very overweight (obese), or if you have been taking Emtriva or similar products for a long time.
Emtriva can cause changes or accumulation of body fat in your upper back and neck ("buffalo hump"), breast, and around the middle of your body. Loss of fat from your legs, arms, and face can also occur.
If you have hepatitis B virus (HBV) and stop taking Emtriva, your HBV can worsen.
Changes in your immune system can occur when you start taking Emtriva. Your immune system can get stronger and begin to fight infections that have been hidden in your body for a long time. Call your doctor immediately if you start having new symptoms after starting Emtriva.
Who should not take Emtriva?Do not take Emtriva if you are allergic to it or any of its ingredients.
Do not take Emtriva if you are already taking other HIV medications containing the same or similar active ingredients (such as Atripla, Complera, Truvada, Combivir, Epivir, Epivir-HBV, Epzicom, or Trizivir).
What should I tell my doctor before I take the first dose of Emtriva?Tell your doctor about all prescription, over-the-counter, and herbal medications you are taking before beginning treatment with Emtriva.
