maraviroc oral Warnings

This medication may rarely cause serious liver problems. Symptoms of a serious allergic reaction may occur before liver problems develop. Tell your doctor immediately if you notice any symptoms of a serious allergic reaction or possible liver damage such as: rash, persistent nausea/vomiting, yellowing eyes/skin, dark urine, extreme tiredness. (See also Side Effects section.)

maraviroc oral Uses

Maraviroc is used with other HIV medications to help control HIV infection. It helps to decrease the amount of HIV in your body so your immune system can work better. This lowers your chance of getting HIV complications (such as new infections, cancer) and improves your quality of life. Maraviroc belongs to a class of drugs known as entry inhibitors. It works by blocking the HIV virus from infecting healthy immune cells (T-cells).

Maraviroc is not a cure for HIV infection. To decrease your risk of spreading HIV disease to others, do all of the following: (1) continue to take all HIV medications exactly as prescribed by your doctor, (2) always use an effective barrier method (latex or polyurethane condoms/dental dams) during all sexual activity, and (3) do not share personal items (such as needles/syringes, toothbrushes, and razors) that may have contacted blood or other body fluids. Consult your doctor or pharmacist for more details.

How to use maraviroc oral

Read the Medication Guide provided by your pharmacist before you start using maraviroc and each time you get a refill. If you have any questions, consult your doctor or pharmacist. Take this medication by mouth with or without food, usually twice daily or as directed by your doctor.

The manufacturer directs not to split, crush, or chew the tablet before taking it. However, many similar drugs (immediate-release tablets) can be split, crushed, or chewed. Follow your doctor's directions on how to take this medication.

Dosage is based on your medical condition, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

It is very important to continue taking this medication (and other HIV medications) exactly as prescribed by your doctor.

This medication works best when the amount of drug in your body is kept at a constant level. Therefore, take this drug at evenly spaced intervals. To help you remember, take it at the same times each day.

Do not take more or less of this drug than prescribed or stop taking it (or other HIV medicines) even for a short time unless directed to do so by your doctor. Doing so may cause the amount of virus to increase, make the infection more difficult to treat (resistant), or worsen side effects.

maraviroc oral Side Effects

See also Warning section.

Cough, stomach pain, or tiredness may occur. Lightheadedness or dizziness while standing may also occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Some people may experience worsening of a previous medical condition (such as an old infection) as their immune systems improve, or develop new conditions because their immune systems have become overactive. This reaction may occur at any time (soon after starting HIV treatment or many months later). Tell your doctor right away if you have any serious side effects, including: unexplained weight loss, persistent muscle aches/weakness, joint pain, numbness/tingling of the hands/feet/arms/legs, severe tiredness, vision changes, severe/persistent headaches, signs of infection (such as fever, chills, trouble breathing, cough, non-healing skin sores), signs of an overactive thyroid (such as irritability, nervousness, heat intolerance, fast/pounding/irregular heartbeat, bulging eyes, unusual growth in the neck/thyroid known as a goiter), signs of a certain nerve problem known as Guillain-Barre Syndrome (such as difficulty breathing/swallowing/moving your eyes, drooping face, paralysis, slurred speech).

Seek immediate medical attention if any of these rare but very serious side effects occur: chest/jaw/left arm pain.

A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any of the following symptoms: rash, rash with fever, skin peeling/blisters, mouth sores, redness/swelling of the eyes, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
