The medicine prescribed by the doctor said 3 times a day, but I only take it 2 times a day, and some

It works, but it's not very effective.

Why do some doctors say that you should take it 3 times a day, while some medicine says that 2 times a day is enough? This is related to the metabolism of the drug itself in the human body. The medicine is good to eat, and part of it is absorbed into the blood circulation.

The other part is excreted. The part that enters the blood circulation and works in the body, mainly depends on its concentration. Just after taking the medicine, the concentration of Chinese medicine in the blood is relatively high, which can play a role in killing bacteria and so on, and can cure diseases.

But as time passes, part of the medicine in the blood has already played the role of killing bacteria, or excreted through urine, or decomposed by some substances in the human blood, in short, the remaining medicine in the blood is less, and it cannot play a bactericidal effect, so you have to take a second medicine to make its concentration rise back.

Some drugs metabolize slowly, so just take them twice or once a day, and some drugs metabolize quickly, so you have to take them 3 times a day or more. How many times is the conclusion of the experiment.

So you have to follow your doctor's instructions.

Medicine. Otherwise, it may be effective at the time of taking the medicine, and most of the time the effect is not good, and the disease will not be cured.

The doctor stipulates that if you eat three times a day, you should eat three times, and if you eat less once, the concentration of the drug in your body will not reach the ** standard. Of course, if you are in good health and are general cold medicines, you will only get better slowly; But if it's a serious illness such as kidney disease, or hormone medications, you must listen to the doctor. In short, unless you understand medicine, it's better to listen to the doctor.

The half-life of the drug is determined by the half-life of the drug metabolism in the body, and the half-life refers to the time when the drug drops to half after reaching the peak in the body, and the drug should be used in three times in two times, and the direct result is that the drug in the body does not reach the required blood concentration, the effect is weakened or disappeared, and the degree of influence is related to the nature of the drug. Failure to reach blood levels may be ineffective, such as sulfonamide antibiotics and cardiac glycosides.

The instructions of many oral drugs usually state in the usage column "X tablets three times a day".When we go to the pharmacy or pharmacy to pick up the medicine, the pharmacist will also tell us to take it "X tablets three times a day".It is generally believed that three times a day refers to three meals a day, taken orally before or after meals.

Actually, this is wrong.

Taking the drug before and after three meals will make the drug have a higher blood concentration in the body during the day, and even cause drug poisoning; At night, if you don't take medicine overnight, the blood concentration will inevitably drop, which will affect the best effect.

The effect is definitely not too good, the drug has a half-life in the body, and it will be invalid after a certain period of time, and then you have to take the next meal.

Try to eat twice and increase the dosage by one but do not exceed the maximum dose.

There is no effect, and the drug will become invalid before the half-life reaches the human body. The concentration of the drug action is not reached.

You're going to get worse off that way.

It is also effective, but the effect will be weakened and the disease will be prolonged.

Three times a day, that is, once every eight hours, because the concentration of the drug in the blood decreases over time, and only a sufficient concentration will have a ** effect. But generally speaking, three times in the morning, noon and evening is also fine. Once every six hours four times a day, and once in the middle of the night if the condition is severe.

If you take the medicine prescribed by the hospital every eight hours, the doctor will tell you, the general three times a day refers to four times a day after meals, which is once every six hours.

You don't eat 3 times a day? That's called a course of treatment.

You can't become fat by eating in one bite.

Remember to adopt it.

Just ask the doctor what time you eat.

Of course not, if you think about it, can you eat three meals a day?

Most drug labels or labels state to be taken several times a day. Many people take medicine, often understanding three times a day as a day during the day. Schedule your medication in the morning, noon, and afternoon, or before or after meals.

Actually, three times a day means 24 hours a day.

Three times a day, it is formulated based on the change in the concentration of the drug in a person's blood over a 24-hour period. Therefore, the correct time to take the medication is to take it every 8 hours. If the interval between two doses is too long, it will affect the efficacy; If the interval between two doses is too short, it will increase the toxicity of the drug.

Considering people's daily routines, three times a day is relative to 24 hours.

The medication should be taken at 7 a.m., 3 p.m., and 10 p.m.

Three times a day or twice a day" is particular.

For example, the label of the drug or the single drug bag or label of the pharmacy says: "Take three times a day, before meals", so patients should take the medicine on time before three meals every day. Actually, this is unscientific.

"Three times a day" is prescribed according to the experimental determination of the metabolic rate of the drug in the human body, that is, it is divided into 3 stages according to the 24 hours a day, and the drug is taken once every 8 hours. In this way, a stable blood concentration (the concentration of the drug in the blood) in the body can be ensured to achieve a better effect. If the time of the three doses is scheduled during the day, the blood concentration will be too high during the day, which will bring danger to the human body, and the treatment will not be achieved at night.
