delavirdine oral Warnings
delavirdine oral 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. Delavirdine belongs to a class of drugs known as non-nucleoside reverse transcriptase inhibitors (NNRTIs).
Delavirdine 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 delavirdine oral
Read the Patient Information Leaflet provided by your pharmacist before you start taking delavirdine 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 3 times daily or as directed by your doctor. The 200-milligram tablets cannot be dissolved and must be swallowed whole.
If you have a condition of little or no stomach acid (achlorhydria), you should take delavirdine with an acidic beverage such as orange or cranberry juice.
If you are also taking an antacid or a buffered form of the medication didanosine, take it at least 1 hour before or after delavirdine.
It is very important to continue taking this medication (and other HIV medications) exactly as prescribed by your doctor. Do not skip any doses. Do not increase your dose, take this drug more often than prescribed, or stop taking it (or other HIV medicines) even for a short time unless directed to do so by your doctor. Skipping or changing your dose without approval from your doctor may cause the amount of virus to increase, make the infection more difficult to treat (resistant), or worsen side effects.
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.
delavirdine oral 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).
Tell your doctor immediately if any of these unlikely but serious side effects occur: mental/mood changes (such as depression), signs of liver problems (such as persistent nausea, vomiting, stomach/abdominal pain, severe tiredness, yellowing eyes/skin, dark 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.
Delavirdine can commonly cause a rash that is usually not serious. A rash may occur within 1 to 3 weeks after you start delavirdine treatment. It appears mainly on the upper body and arms, but may also appear on the neck and face. After consultation with the doctor, most people can continue taking delavirdine and treat the rash if it is not severe. Non-serious rashes usually last less than 2 weeks. However, a severe rash or a rash with signs of a severe reaction requires immediate medical attention. Signs of a severe reaction that usually appear within the first 3 days of a serious rash include: fever, blisters, mouth sores, eye redness/swelling, swelling in other areas of the body, or muscle/joint pain. Since you may not be able to tell a common rash apart from a rare rash that could be a sign of a severe reaction, always seek immediate medical attention if you develop any rash or any of these symptoms.
A very serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction may include: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
