Before meals on an empty stomach!Do you really take medicine?

After seeing the doctor and prescribing the medicine, the drugs we have received in the pharmacy will have a prompt label. There are words such as "Once once a day, taking it before going to bed", "Twice a day, taking an empty stomach", "Three times a day, taking it after meals" and other words. There will also be abbreviations such as QD, BID, TID, etc. on the prescription. Do you understand the exact meaning of these texts?

"Empty" is about "before meal"? Is it taken three times a day with three meals? In fact, these are very common misunderstandings. How to take medicine is a positive solution? This time we invited Lin Ni and Mai Shaoyu Pharmacists to explain some most commonly used medication tips.

Medicine box label: "empty stomach" ： "before meal"

First of all, talk about the most common medication tips on the pill box label. Ask yourself and your family, did you eat it right before?

Take an empty stomach: refers to 1 hour before meal or 2 hours after meals.

Take before meals: 15-30 minutes before meals.

Take in the meal: Take at the same time as the food, that is, take the medicine for a little meal, and continue to eat after taking it.

Take after meals: 15-30 minutes after meals.

Morning clothes: Take in the morning.

Take before bed: 15-30 minutes before going to bed.

Take it if necessary: ​​take it as needed.

What is the common abbreviation of doctors?

In addition, there are often abbreviations such as QD, BID, TID, QID, etc. on the prescriptions of doctors. What do these words mean?其实，它们都由拉丁语演化而来，QD（quaque die）是一日一次，bid（bis in die）是一日两次，TID（ter in die）是一日三次，qid（quater in die， Four times a day).

QD: once a day

Pharmacist Mai Shaoyu reminds that the best time to take drugs once a day, otherwise it may discount the effects and increase the risk of side effects. If there are no special requirements, if you set the alarm clock at 7 o'clock every morning, take the medicine on time.

However, some drugs can choose the best medication time according to the corresponding disease rules to achieve the best efficacy. For example, most long -acting antihypertensive drugs are suitable for taking in the morning, while lipid -lowering drugs are suitable for at night.

BID: twice a day

Generally speaking, the best time to maintain such drugs for each time is 12 hours. Therefore, if you are used to taking the first medicine at 8 o'clock in the morning, it is best to be around 8 o'clock in the evening, not simple "early, once late". However, there are exceptions, such as a certain antidepressant drug that needs to be taken in the morning and noon, because after 4 pm after 4 pm, it will affect sleep.

TID: Three times a day

When the medication tips are "three times a day", the three meals are the most common misunderstanding of medication, because this will cause the blood concentration of the daytime to be too high, and the side effects will increase, and the concentration of the night blood drug will be too low, which will affect the efficacy.

The correct method of "three times a day" is 8 hours interval. For example, antibiotics that have strict requirements and dependence on time, we can three times a day at 6 o'clock in the morning, once every 2 pm, once every 10 pm, so that it is not easy to arrange it. Cause adverse drug reactions can also achieve better curative effects.

However, it is worth noting that not all the drugs must abide by each 8 hours a day, such as hypoglycemic drugs. Generally, blood sugar is increased after eating. At this time, it is necessary to take three meals three times a day.

qid: four times a day

If there are no special requirements, it is generally recommended to take each time after three meals, and take it again before going to bed. Generally, the interval is more than 4 hours.

In the end, the pharmacist reminded warmly that if there is no special requirements, use warm water to take medicine. The most recommended method is to give it to warm water at about 200 ml. Too much or less generally is not conducive to drug absorption.
