The half-life of the drug is the time taken for the plasma concentration of the drug to reduce to 50% of its original value.
Units of half life are hour, minute, or day.
The formula for calculation half life of a drug is as follows:
Cp is the concentration at time one and Cp/2 is the concentration at time one half-life later:-
In( Cp/2) = In Cp - Kel . t1/2
half life of the drug (t 1/2) = 0.693/kel
The term half-life refers to the period in which the radioactivity or number of atoms of a radioactive substance decreases by half. The term can be applied to any substance whose quantity decreases exponentially with time.
The half life of a drug is the time in which it takes half of the drug's dose that you ingested to be eliminated from your body.
The time that it takes for half of a medication to be processed and leave your system.
The half life refers to how long a dose of the medication affects the body. Some drugs stay effective for weeks, while others are measured in hours.
The time it takes for half of the drug to be eliminated from your body.
When a doctor explains the half life of a dosage of medication they are explaining how long it takes for each dosage of medication to take effect for one's body type.
No! Never cut a tablet labeled XR in half it is an extended release tablet made to be slowly broken down by the body. If you break it in half you will receive to much medication at a time. Talk to you doctor about lowering you dosage or about taking the 20mg every other day.
If the dosage you need is less than half of a scored tablet, you could notify your doctor and perhaps get a prescription for a smaller dose pill...or if it is water soluble, you can crush the pill and place it in water. For example, if your dosage is 1/3 of the pill that you have, you could take 3 teaspoons of water and mix with the crushed/powdered contents thoroughly, then for your dosage, you would take 1 teaspoon of the mixture...and discard the remainder (other 2 teaspoons). Some pills cut into fourths well, others do not break evenly enough to assure you are getting the same amount of medication every time.
You can decrease the dosage. I would recommend half a tablet for 2 days. If your depression doesn't come back and you stay positive, then you can try to slowly (!) decrease your dosage more until you are not needing the medication.
Your doctor needs to advise on this, it probably depends on the dosage. My doctor had me start by skipping every other day, and then increasing from there. I don't recall if we cut the pills in half during this period.
Wellbutrin has caused my acne. It's gotten worse over the last few months. I finally figured out what was causing it after visiting the doctor twice and she couldn't figure it out. I have never had acne before taking Wellbutrin. This medication has lots of good effects but the only way to cure my acne has been to cut my dosage in half.
There is no way to answer this question without knowing what the medication was perscribed for and what the perscribed dosage amount was. Also, if it was perscribed for ADD, you would need to measure and report the effect of the medication on your ADD symptoms.
I am not a doctor but I do have a number of years experience with antidepressants. First thing is to take them . It takes weeks to get the the level to the point where it helps you. The second is that if prescribed by your family doctor the dose maybe to low. I was told by my psychiatrist that "most" GP's don't even get to half the dose needed. So if possible see a psychiatrist for the proper dosage. Lastly it took about 5 tries to get the right medication that suited me , we are all different and react differently
I have 2 mg tablets, but I quarter or half them.
Your doctor should help wean you off of it, if your doing it alone, you can probably start by lowering your daily dosage by cutting the pills in half for a month or 2, but it might be better and safer to have your doctor wean you off.
Yeah!!
it depends on the dosage but you will likely hallucinate
There are 6 rights to medication delivery. The right patient, right medication, right dosage, right time, right route (where the medication goes), and the right documentation. Probably the most common mistake is the right time. Nurses in most institutions have a one hour window, 1/2 hour before and 1/2 after the prescribed time to give the medication and it is missed sometimes. Documentation errors cover a large percentage of medication errors as well. A 2006 study showed that 1.5 million people each year suffered a medication error and 7000 people died as a result of medication errors. Over half of all medication errors occur in nursing homes.
