I have taken 8 in the last 16 hours. They don´t seem to be working any more.
I was researching the subject when I found this question.
My doctor prescribed 2 a day
Ask your doctor. We cannot advise on such matters as we do not know your medical history
take two tablets orally (by Mouth) every 4 to 6 hours
The recommended dose is 2 tablets every 6 hours. So 3.
To be safe you should ask your doctor who treats you.
i take one dose of 54mg a day.
You would have to take approximately 70 tablets.
Take one to two tablets every 4 to 6 hours as needed do not exceed 8 tablets
i would not advise taking any concerta while taking lexapro. I am currently taking lexapro and have taken concerta about 7 times. Each time i took concerta i would hear many scary voices in my head. i looked up the psycotic effects of concerta and they said that a side effect of concerta is hearing voices if you are on an antidepressant
Concerta (methylphenidate) has a half-life of about 3.5 hours, meaning it takes approximately this time for the body to eliminate half of the dose. It typically takes about 5 half-lives for a drug to be mostly cleared from the system, so Concerta 54mg would likely take around 18 to 30 hours to be eliminated completely. However, individual factors such as metabolism, age, and overall health can influence this timeframe.
There is no such thing as 54mg tablets or capsules of Adderall. There is 54mg capsules of Concerta, another common ADHD medication, which would wear off anywhere from 6-10 hours depending on the person. 4 of them is most likely too many and could potentially be toxic depending on the person as well.
It means take one tablet by mouth twice a day. Since a day is 24 hours, dividing that by two means one tablet every 12 hours.
I wouldn't unless that's what the doctors orders are. If you are only supposed to take one only take one. I work for a psychiatrist and although I have seen them switch someone from Concerta to Adderall or vice versa, I have never seen them prescribe both at once or recommend that they switch in the middle of the day. Concerta is long acting and although you might feel a come down feeling after it peaks, it is active in your body for on average 12 hours from the time it is taken. If you take the Adderall while the Concerta is still in your system I doubt it would make you feel better and could even make you feel worse.
