Uses

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. Didanosine belongs to a class of drugs known as nucleoside reverse transcriptase inhibitors-NRTI. Didanosine 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 DIDANOSINE (DDI) SOLUTION - ORAL

HOW TO USE: Read the Medication Guide provided by your pharmacist before you start using didanosine and each time you get a refill. If you have any questions, ask your doctor or pharmacist. Take this medication by mouth usually 1-2 times a day on an empty stomach, at least 30 minutes before or 2 hours after a meal, or as directed by your doctor. Shake the bottle well before measuring 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. Didanosine solution is mixed by your pharmacist with an antacid to form a suspension. The antacid can interfere with your body's ability to absorb certain drugs, especially if you take them around the same time. These drugs include quinolone antibiotics (such as ciprofloxacin, levofloxacin), tetracycline antibiotics (such as doxycycline, minocycline), levodopa, thyroid medications (such as levothyroxine), azole antifungals (such as ketoconazole, itraconazole), and drugs for osteoporosis (bisphosphonates such as alendronate). This is not a complete list. Consult with your pharmacist how long you must wait between doses of your other medications and didanosine solution. Do not take other antacids or acid-lowering drugs (such as cimetidine, omeprazole, ranitidine) with this product without talking with your doctor first. The dosage is based on your weight, medical condition, and response to treatment. 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. For the best effect, take this medication at evenly spaced times. To help you remember, take this medication at the same time(s) every day.

Side Effects

SIDE EFFECTS: See also Warning section. Headache or diarrhea may occur. If any of these effects persist or worsen, notify 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. As your immune system gets stronger, it can begin to fight off infections you already had, possibly causing disease symptoms to come back. You could also have symptoms if your immune system becomes overactive. This reaction may happen at any time (soon after starting HIV treatment or many months later). Get medical help right away if you have any serious symptoms, including: unexplained weight loss, severe tiredness, muscle aches/weakness that doesn't go away, headaches that are severe or don't go away, joint pain, numbness/tingling of the hands/feet/arms/legs, vision changes, signs of infection (such as fever, chills, swollen lymph nodes, 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 trouble breathing/swallowing/moving your eyes, drooping face, paralysis, trouble speaking). This medication can cause severe nerve problems in the hands/feet/legs (peripheral neuropathy). Symptoms may include numbness/tingling/pain in the palms of the hand or soles of the feet. If you experience any of these symptoms, contact your doctor right away so that you can be monitored closely. Your doctor may decide to reduce or stop your dose of didanosine. Tell your doctor right away if you have any serious side effects, including: vision problems (such as blurred vision, difficulty seeing colors), vomiting up blood, belly/abdominal swelling, easy bruising or bleeding. Loss of body fat (such as in the face, arms, and legs) may occur while you are taking this medication. This effect may be permanent. Tell your doctor right away if you notice any changes in body fat. 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.

Precautions

PRECAUTIONS: Before taking didanosine, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details. Before using this medication, tell your doctor or pharmacist your medical history, especially of: pancreatitis, kidney problems, liver problems (such as hepatitis, cirrhosis), nerve problems (such as peripheral neuropathy), alcohol use, high fat levels in the blood (triglycerides), gall bladder problems (such as gallstones), gout. Avoid alcoholic beverages because they may increase your risk for liver problems and pancreatitis. Didanosine may increase your risk of a heart attack. Discuss the risks and benefits of treatment with your doctor and ways to lower your risk of heart disease. Tell your doctor if you have heart problems, if you smoke, or if you have other conditions that increase your risk of heart disease such as high blood pressure, diabetes, or high cholesterol levels. Ask your pharmacist if the antacid used to mix this product contains aspartame. If you have phenylketonuria (PKU) or any other condition that requires you to restrict your intake of aspartame (or phenylalanine), consult your doctor or pharmacist about using this medication safely. Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). Older adults may be at greater risk for pancreatitis while using this drug. During pregnancy, this medication should be used only when clearly needed. Treatment can lower the risk of passing HIV infection to your baby, and didanosine may be part of that treatment. Discuss the risks and benefits with your doctor. It is not known if this medication passes into breast milk. Because breast milk can transmit HIV, do not breast-feed.
