Biphentin is a drug that is used for the treatment of ADHD (attention deficit hyperactivity disorder) as well as narcolepsy: a disorder characterized by excessive daytime sleepiness, sleep attacks, hallucinations and sudden loss of muscle tone.

The drug was first approved in 2009 in Canada. In 2010, it became the first dosage form of methylphenidate to be approved in Ireland. It has been marketed by Novartis since its approval in Canada.

Methylphenidate (MPH) is a psychostimulant medication. It is used as a recreational drug and as a treatment for attention deficit hyperactivity disorder (ADHD) and severe cases of depression.

The original patent was owned by CIBA, now Novartis Corporation.[1] It was first licensed by the U.S. Food and Drug Administration (FDA) in 1955 for treating what was then known as hyperactivity.[2][3]

Methylphenidate acts by blocking the dopamine transporter and norepinephrine transporter, leading to increased concentrations of dopamine and norepinephrine within the synaptic cleft. It has actions similar to other psychostimulants. The short-term benefits and cost effectiveness of methylphenidate are well established.[4]

biphentin dosage is one of the most popular medicines for the treatment of ADHD. It has been cited in hundreds of articles and reports around the world and was first introduced in 1996. Its efficacy is well-documented and backed by scientific research, which makes it a very attractive medication for those suffering from ADHD.

biphentin dosage comes in two forms: biphentin dosage capsule and biphentin dosage tablet. The capsules are available in 5 mg, 10 mg, 15 mg, 20 mg, 30 mg, and 60 mg dosages. The tablets are available in 5 mg and 10 mg dosages. Both types come in once-daily formulations that last for 24 hours.

It should be noted that the capsules are easier to split into smaller dosages than the tablets because they are not scored (i.e., you cannot break them with your fingers).

Biphentin is available as 5 mg, 10 mg, 15 mg, 20 mg and 30 mg capsules. The usual dose for children is 10-30 mg once daily or twice daily. For adults the usual dose is 60 mg a day.

If you miss a dose, take it as soon as possible, unless it is almost time to take your next dose. If the next dose is due within 3 hours, skip the missed dose. Do not take two doses at the same time.

You should never stop taking Biphentin suddenly because this can result in withdrawal symptoms such as abdominal cramps, vomiting, sweating and sleep problems (insomnia). If you want to stop taking Biphentin, your doctor will gradually lower your dose over one or two weeks before stopping completely.

If you are concerned about any side effects you experience while taking Biphentin, talk to your doctor or pharmacist.

Biphentin vs Adderall

biphentin vs adderall

Adderall and Ritalin are two medications often used to treat ADD and ADHD.

However, they’re also frequently abused.

Adderall is a stimulant medication often prescribed to treat attention deficit hyperactivity disorder (ADHD). It can also be prescribed to treat narcolepsy. A generic version of the drug is also available. Adderall consists of a combination of amphetamine and dextroamphetamine. Both drugs work by increasing levels of dopamine, norepinephrine, and serotonin in the brain. These chemicals play a role in controlling impulses and hyperactivity. In general, Adderall is effective for treating ADHD symptoms such as: Trouble staying focused on tasks or activities



However, it can also cause some unwanted side effects including: Loss of appetite

Weight loss

Difficulty falling asleep or staying asleep (insomnia)




Dry mouth/thirst Adderall may also be habit-forming. In addition, it’s important to note that there have been reports that Adderall has contributed to sudden death in people with heart problems or heart defects. This is why the drug is

When comparing Biphentin vs. Adderall, there are a few things to consider:

Biphentin comes in two different doses: 10 mg and 15 mg capsules. These capsules can be opened and sprinkled into food if needed. However, it is not recommended for children under the age of 6 years old.

Adderall comes in five different doses: 5 mg, 7.5 mg, 10 mg, 12.5 mg, 20 mg, and 30 mg tablets. These tablets can be cut into smaller sizes or crushed and mixed with water as well. This drug is only approved for adults and children over 6 years old.

Adderall contains both d-amphetamine and l-amphetamine salts, whereas Biphentin contains just d-amphetamine salts.

Adderall is taken once or twice daily, whereas Biphentin is taken up to three times per day (usually two).

Adderall may cause more insomnia, loss of appetite, mood swings/irritability, dry mouth and nausea than Biphentin does as a side effect. As always though, these side effects vary from person to person and are not guaranteed to occur even if they are common side effects associated with the medication.

I am currently prescribed Vyvanse 70mg and Adderall 40mg. I typically take the Vyvanse in the morning. I have been having a hard time focusing at work in the afternoons so my doctor suggested taking one of the addies half an hour before work.

I am thinking of switching to Biphentin because it is longer acting than both Vyvanse and Adderall and this way I could take just one pill in the morning. Would this be a good idea? I’ve also heard mixed things about Biphentin’s effectiveness.
