Taking medicine three times a day refers to how many hours you take it once a day

Taking medicine three times a day refers to how many hours you take it once a dayGenerally, three times refers to three times in the morning, noon and evening, with an interval of about 6 hours! Unless your medicine has special instructions, it is recommended to ask your primary care doctor, and there is a difference between taking before and after meals.

Ideally, if it is once every 8 hours and does not have too much impact on work and life, it is enough to do it once at 6 a.m., once at 2 p.m., and once at 22 p.m. Or basically adjust it according to this time period.

You must accurately understand the special way you take the medicine, and then arrange a better time for taking the medicine.

For drugs taken once a day (e.g., aspirin enteric-coated tablets, nifedipine controlled-release tablets);

Medications that must be taken after meals (e.g. calcium carbonate tablets, bismuth aluminate capsules, etc.);

Medications that must be taken with or after taking a meal (e.g., acarbose, glimepiride, etc.);

Medications that must be taken on an empty stomach or away from mealtimes (e.g. alendronate tablets, voriconazole capsules, etc.).

Don't misunderstand the medication "three times a day": The medication method indicated in the drug package is generally three times a day, so many people are accustomed to understanding it as taking it after three meals, that is, taking the medicine three times a day after breakfast, lunch and dinner. In fact, the interval between the use of some drugs is more important than the number of times, such as long-term medication for chronic disease patients, if the medicine that should have been taken in 24 hours is taken in 12 hours, the uneven blood concentration will affect the efficacy.

Experts point out that this situation is most likely to occur with antibiotic drugs. Because the concentration of the drug in the blood and the lesion area needs to be maintained at a certain level to kill bacteria, the drug should be taken every 8 hours three times a day. If you follow most people's eating habits, take it at 7 a.m., 12 noon, and 6 p.m., with intervals of 5 hours, 6 hours, and 13 hours respectively.

In this way, the blood concentration will be high during the day and low at night, and the bactericidal effect will only play an effect during the day, and at night the bacteria will multiply in large numbers, which can easily cause bacterial resistance, and the original effective drugs will also be reduced or even ineffective.

Therefore, patients taking antibiotics** are advised to schedule their medication at 6 a.m., then 2 p.m., and then 10 p.m. In this way, it will not disrupt the original routine of life, and there is no need to get up in the middle of the night to take medicine. Like antibiotics, anti-epileptic drugs, painkillers, hormone drugs, hyperthyroidism and asthma drugs are also used every 8 hours.

In addition, antihypertensive drugs also have their own special methods of medication. Because the blood pressure value of patients with hypertension may peak once or twice in a day, for example, some people have high blood pressure at 9 a.m. and some people have high blood pressure at 3 p.m., so it is best to take the medicine about 1-2 hours before the peak blood pressure.

Therefore, patients with high blood pressure should use a sphygmomanometer to measure their blood pressure every 1 hour to find out the peak time period of their blood pressure in a day so that they can take medication correctly. Of course, some medications are taken with reference to three meals a day, such as hypoglycemic drugs. Because, blood sugar will only rise after eating, and if this kind of medicine is taken every 8 hours, it will not have the best effect.
