What is Adderall?

This is known as a combination drug which is frequently employed in the United States to cure several kinds of issues. This is basically a central nervous system stimulant that affects the brain and the parts which function within it such as nerves and helps in controlling the actions that result because of them. If we have to summarize the use of this type of drug against one disease, it will be the Attention Deficit Hyperactivity Disorder (ADHD). This is the salt name which is used for amphetamine salts and therefore is not considered as dangerous as some other drugs in the market. It cannot be taken on personal choice but is only prescribed by the doctor under a severe condition. It has a healthy dosage and has to be consumed for around 3 times daily which is relatively more than the other drugs, but that is because its effectivity lasts for about 4-6 hours. The dose can vary but also depends on the type of medicine being consumed. There are capsules available for Adderall which are 10 mg, 20 mg, 30 mg and will be consumed once the doctor confirms the symptoms. This medicine is useful for people who are suffering from many issues and is extremely helpful for matters such as euphoria, change in sex desire, weakness and muscle breakdown. The problems mentioned above are the ones who are medically approved, but there are also some related problems for which it is used as an off-label. These include depression, obesity, sleeplessness, and nausea. Its main drawback is that it is an addictive drug and therefore should be taken with care.
