Biphetamine : Uses, Side Effects, Interactions & More
Biphetamine (Dextroamphetamine and Amphetamine) can be habit-forming. Do not take a larger dose, take it more often, or take it for a longer time than prescribed by your doctor. If you take too much Biphetamine, you may continue to feel a need to take large amounts of the medication, and you may experience unusual changes in your behavior. You or your caregiver should tell your doctor immediately, if you experience any of the following symptoms: fast, pounding, or irregular heartbeat; sweating; dilated pupils; abnormally excited mood; restlessness; irritability; difficulty falling sleeping or staying asleep; hostility; aggression; anxiety; loss of appetite; loss of coordination; uncontrollable movement of a part of the body; flushed skin; vomiting; stomach pain; or thinking about harming or killing oneself or others or planning or trying to do so. Overusing Biphetamine may also cause serious heart problems or sudden death.
Tell your doctor if you or anyone in your family drinks or has ever drunk large amounts of alcohol, uses or has ever used street drugs, or has overused prescription medications. Your doctor will probably not prescribe Biphetamine for you.
Do not stop taking Biphetamine without talking to your doctor, especially if you have overused the medication. Your doctor will probably decrease your dose gradually and monitor you carefully during this time. You may develop severe depression and extreme tiredness if you suddenly stop taking Biphetamine after overusing it.
Do not sell, give away, or let anyone else take your medication. Selling or giving away Biphetamine may harm others and is against the law. Store Biphetamine in a safe place so that no one else can take it accidentally or on purpose. Keep track of how many tablets or capsules are left so you will know if any are missing.
Your doctor or pharmacist will give you the manufacturer’s patient information sheet (Medication Guide) when you begin treatment with Biphetamine and each time you get more medication. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer’s website to obtain the Medication Guide.
Why is this medication prescribed?
Biphetamine (Dextroamphetamine and Amphetamine) is used as part of a treatment program to control symptoms of attention deficit hyperactivity disorder (ADHD; more difficulty focusing, controlling actions, and remaining still or quiet than other people who are the same age). Biphetamine is also used to treat narcolepsy (a sleep disorder that causes excessive daytime sleepiness and sudden attacks of sleep) in adults and children 12 years of age and older. Biphetamine is in a class of medications called central nervous system stimulants. It works by changing the amounts of certain natural substances in the brain.
How should this medicine be used?
Biphetamine comes as an immediate-relase tablet to take by mouth. The immediate-release tablet is usually taken 2 to 3 times daily, 4 to 6 hours apart, with or without food. The extended-release capsule is usually taken upon awakening with or without food. Biphetamine should not be taken in the late afternoon or evening because it may cause difficulty falling asleep or staying asleep. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Biphetamine exactly as directed.
Swallow the extended-release capsules whole; do not chew or crush them. If you are unable to swallow the extended-release capsule, you may open the capsule and sprinkle the entire contents on a teaspoonful of applesauce. Swallow this mixture right away without chewing. Do not store the applesauce and medication mixture for future use, and do not divide the contents of one capsule into more than one dose.
Your doctor will probably start you on a low dose of Biphetamine and increase your dose gradually, not more often than once every week.
Your doctor may tell you to stop taking Biphetamine from time to time to see if the medication is still needed. Follow these directions carefully.
The medication in each product is absorbed differently by the body, so one Biphetamine product cannot be substituted for another product. If you are switching from one product to another, your doctor will prescribe a dose that is best for you.
Other uses for this medicine
Biphetamine should not be used to treat excessive tiredness that is not caused by narcolepsy.
This medication may be prescribed for other conditions; ask your doctor or pharmacist for more information.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature, away from light and excess heat and moisture (not in the bathroom).
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
