Choosing a medication to treat ADHD or narcolepsy is often a trial and error process for physicians. Physicians may compare medications like Adderall and Vyvanse for effectiveness and side effects, as well as consider whether the patient is prone to drug misuse or dependence. They also take into account insurance company restrictions, which may limit the number of pills a patient can get per month.
Misuse of stimulants such as Vyvanse can lead to drug dependence and addiction. Misuse includes taking a medication more frequently or in larger doses than prescribed by a doctor, or using it for purposes other than those approved by the FDA. Abuse can also include injecting a drug, which can have severe and dangerous side effects. Vyvanse is a schedule II controlled substance, so the FDA closely monitors its use and distribution.
If you take too much Vyvanse, you could experience a life-threatening overdose. This can be caused by symptoms such as restlessness, tremors, muscle twitches, trouble breathing, confusion, hostility, hallucinations, a fast heartbeat, or signs of circulation problems, such as numbness, pain, cold feeling in the arms and legs, or unexplained wounds. You may also have a seizure or coma. Get emergency medical help right away if you have these symptoms.
Your doctor may start you on a low dose of Vyvanse and then increase your dose slowly. This way, they can ensure you are receiving the correct dosage for your condition. Your doctor may also adjust your dose to prevent you from developing side effects such as agitation or drowsiness.
Depending on your condition, you may take Vyvanse orally as an oral capsule or chewable tablet. You should take this medication with food and a full glass of water, or as directed by your doctor. Chewable tablets should be fully chewed before you swallow them. Never snort or chew this medication, or combine it with alcohol or other drugs, as this can cause a dangerous side effect called serotonin syndrome.
Tell your doctor about any other medicines, herbs, vitamins, or supplements you are taking. These can interact with lisdexamfetamine and cause serious side effects. Your doctor may also want to avoid medicines that affect your mood, such as antidepressants, other stimulants, or certain narcotics.
Some medicines can affect your blood sugar levels, so you will need to let your doctor know if you have diabetes. You should also inform your doctor if you have a family history of diabetes, kidney disease, or liver disease.
You should not take this medicine if you are allergic to lisdexamfetamine or to any other ingredient in Vyvanse. This medication can cause a serious reaction in people with a history of glaucoma or high blood pressure. It is also important to tell your doctor if you have had any seizures or other mental health problems. Do not drive or do other activities that require alertness while you are taking this medicine. Also, tell your doctor if you have ever had suicidal thoughts or behaviour while you are taking this medication. 40 mg vyvanse
