Treats Disease/Condition

HIV

Uses

This drug 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. This product may also be used to lessen the risk of HIV infection after contact with the virus (for example, due to a needle stick). Ask your doctor for more details.

How To Use

Take this medication by mouth as directed by your doctor, usually once or twice daily. Fosamprenavir tablets may be taken with or without food. If you are taking fosamprenavir suspension, shake the bottle well before each dose. Carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose. Adults should take the suspension without food. Children should take the suspension with food. If vomiting occurs less than 30 minutes after taking a dose, repeat the dose. 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 time(s) each day.

Side Effects

Diarrhea, nausea, vomiting, and headache may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly. 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). Tell your doctor right away if you have any serious side effects, including: increased thirst/urination, signs of a kidney stone (such as pain in side/back/abdomen, painful urination, blood in the urine). Changes in body fat may occur while you are taking this medication (such as increased fat in the upper back and stomach areas, decreased fat in the arms and legs). The cause and long-term effects of these changes are unknown. Discuss the risks and benefits of treatment with your doctor, as well as the possible use of exercise to reduce this side effect. Get medical help right away if you have any very serious side effects, including: signs of a heart attack (such as chest/jaw/left arm pain, shortness of breath, unusual sweating). Fosamprenavir can commonly cause a rash that is usually not serious. However, you may not be able to tell it apart from a rare rash that could be a sign of a severe reaction. Therefore, get medical help right away if you develop any rash. A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, 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.

Drug Interactions

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval. Some products that may interact with this drug include: certain HIV protease inhibitors (such as lopinavir, tipranavir), boceprevir, telaprevir. Other medications can affect the removal of fosamprenavir from your body, which may affect how fosamprenavir works. Examples include etravirine, rifampin, St. John's wort, among others. Fosamprenavir can speed up or slow down the removal of other medications from your body, which may affect how they work. Examples of affected drugs include alpha blockers (such as alfuzosin), certain benzodiazepines (midazolam, triazolam), cisapride, delavirdine, ergot alkaloids (such as dihydroergotamine, ergotamine), fluticasone, pimozide, ranolazine, rivaroxaban, drugs to treat erectile dysfunction-ED or pulmonary hypertension (such as sildenafil, vardenafil), certain drugs to treat irregular heartbeat (such as flecainide, propafenone), certain "statin" cholesterol drugs (lovastatin, simvastatin), salmeterol, among others. This medication may decrease the effectiveness of hormonal birth control such as pills, patch, or ring. This could cause pregnancy. Talk to your doctor about additional or alternative reliable forms of birth control, and always use an effective barrier method (latex or polyurethane condoms/dental dams) during all sexual activity to decrease the risk of spreading HIV to others. Tell your doctor if you have any new spotting or breakthrough bleeding, because these may be signs that your hormonal birth control is not working well.

In Case of Overdose

If someone has overdosed and has serious symptoms such as passing out or trouble breathing, call 911. Otherwise, call a poison control center right away. US residents can call their local poison control center at 1-800-222-1222.

In Case of Missed Dose

It is important not to miss doses of this drug. If you miss a dose by less than 4 hours, take it as soon as you remember. However, if you miss a dose by more than 4 hours, skip the missed dose and resume your usual dosing schedule. Do not double the dose to catch up.

Storage

Store the tablets in a tightly closed container at room temperature away from light and moisture. Do not store in the bathroom. Keep all medications away from children and pets. Store the suspension in a tightly closed container at room temperature or in the refrigerator. Refrigeration may improve the taste of the suspension. Do not freeze.
