-

- STORAGE
-
- Amantadine should be stored at room temperature (never frozen) in a
- tightly closed container. This medication should never be frozen.
-
- USES
-
- Amantadine is used to treat the symptoms of Parkinson's disease and to
- prevent or treat respiratory tract infections caused by influenza A virus. It
- is thought to relieve the symptoms of Parkinson's by increasing the levels of
- dopamine, an important chemical in the brain, which is lacking in these
- patients. Amantadine is also an antiviral agent that slows the growth of the
- influenza virus.
-
- TREATMENT
-
- Amantadine can be taken on an empty stomach or with food or milk.
- Each dose of the oral syrup should be measured carefully with a specially
- designed 5-ml measuring spoon. If you are taking amantadine to treat a viral
- infection, you should start taking it as soon as possible after exposure to
- the infection. Continue to take this medication for the entire time
- prescribed by your doctor (usually seven to 14 days), even if the symptoms of
- infection disappear before the end of that period. If you stop taking the
- drug too soon, the virus is given a chance to continue growing and the
- infection could recur.
- Amantadine works best when the level of medicine in your bloodstream is
- kept constant. Therefore, take the doses at evenly spaced intervals day and
- night. For example, if you are to take two doses a day, the doses should be
- spaced 12 hours apart.
- If you are taking amantadine to treat Parkinson's disease, you should
- know that the full effects of this medication may not become apparent for
- several weeks.
- If you miss a dose of this medication, take the missed dose as soon as
- possible, unless it is almost time for the next dose. In that case, don't
- take the missed dose at all; just return to your regular dosing schedule. Do
- not double the next dose.
-
- SIDE EFFECTS
-
- Minor.
-
- Constipation, dizziness, dry mouth, fatigue, headache, insomnia,
- loss of appetite, nausea, or vomiting. These side effects should gradually
- disappear.
- To relieve constipation, increase the amount of fiber in your diet (fresh
- fruits and vegetables, salads, bran, and whole-grain breads), exercise, and
- drink more water (unless your doctor directs you to do otherwise).
- If you feel dizzy, sit or lie down for a while; get up slowly from a
- sitting or reclining position, and be careful on stairs.
- To relieve mouth dryness, chew sugarless gum or suck on ice chips or hard
- candy.
-
- Major.
-
- Tell your doctor about any side effects that are persistent or
- particularly bothersome. IT IS ESPECIALLY IMPORTANT TO TELL YOUR DOCTOR about
- anxiety, confusion, convulsions, depression, difficulty urinating, fluid
- retention, hallucinations, purplish-red spots on the skin, shortness of
- breath, skin rash, slurred speech, or visual disturbances.
-
- INTERACTIONS
-
- Amantadine interacts with several other types of drugs:
- 1. Concurrent use of amantadine and alcohol can lead to dizziness,
- fainting, and confusion.
- 2. Phenothiazine tranquilizers and tricyclic antidepressants in
- combination with amantadine can lead to confusion, hallucinations, and
- nightmares.
- BE SURE TO TELL YOUR DOCTOR about any medications you are currently
- taking, especially any of those listed above.
-
- WARNINGS
-
- * Tell your doctor about unusual or allergic reactions you have had to
- any medications, especially to amantadine.
- * Before starting to take amantadine, tell your doctor if you now have or
- if you have ever had epilepsy, heart or blood vessel disease, kidney disease,
- liver disease, mental disorders, or stomach ulcers.
- * If this drug makes you dizzy, avoid taking part in any activity that
- requires alertness, such as driving a car or operating potentially dangerous
- equipment.
- * If you are taking amantadine to treat Parkinson's disease, do not stop
- taking the medication unless you first consult your doctor. Stopping the drug
- abruptly may lead to a worsening of the disease. Your doctor may, therefore,
- want to reduce your dosage gradually to prevent this from occurring. In
- addition, tolerance to the benefits of amantadine can develop in several
- months. If you notice a loss of effectiveness, CONTACT YOUR DOCTOR.
- * Be sure to tell your doctor if you are pregnant. Although amantadine
- appears to be safe in humans, birth defects have been reported in the
- offspring of animals that received large doses during pregnancy. Also, tell
- your doctor if you are breast-feeding an infant. Small amounts of amantadine
- pass into breast milk and can cause side effects in the nursing infant.
