Medicines are poisonous to some extent. To avoid "poisoning", doctors give you three super effective methods

Many people are extremely afraid when taking medicine, even though they don't say it. It’s not everyone’s fault. Even if you don’t know much about medicine, most people know that medicine has side effects.

And if you have a little understanding of drugs... you will know that in addition to the side effects within the scope of reasonable use of drugs, there are also toxic reactions, allergic reactions and other adverse reactions caused by unreasonable use of drugs.

Are you scared when you are about to take medicine? Don't worry, these adverse reactions are not so easy to occur.

Today, Ding Dang invited Mr. Wang Miao, a master of pharmacology, to explain the reason in detail.

Is it true that all medicines are poisonous?

How to avoid "poisoning"?

There are probably quite a few people who have this idea. After swallowing a pill, they feel bad.

I would just like to say this about this idea:

Please correctly understand the saying "All medicines are poisonous to some extent"!

"All medicines are three-part toxic" does not mean "all medicines are three-part toxic". If we must say it, its three-part toxicity is reflected in:

Toxic in excessive doses;

It is toxic when accumulated in excess;

Toxic in special cases.

So how do we avoid these "poisoning" situations?

1. Take medication as directed by your doctor

The first situation is easy to deal with. As long as we follow the doctor's advice or take the medicine according to the instructions, the drug concentration will be maintained within a relatively safe range and will not exceed the line of "toxic reaction".

If you have naughty children at home, you must keep the medicine away and not put it where the children can get to it.

2. Don’t overeat

To avoid the second situation, first of all, you should pay attention to the time of taking the medicine. If the instructions say not to take it for more than three days, then don't take it for a week.

Secondly, the elderly, children, and patients with liver and kidney diseases have slower metabolism, so they need to pay attention to the problem of accumulation, especially those products with the words "Use with caution in the elderly and children" or "Use with caution in patients with liver and kidney diseases" in the instructions. It is best to consult a doctor or pharmacist before taking them.

It is not easy to produce poison when taking medicine normally.

3. Pay attention to your body’s reactions after taking medication

Special circumstances are low-probability events, such as "idiosyncratic reactions".

A small number of people are particularly sensitive to certain drugs and may have a larger reaction even at normal doses. For example, some people cannot use penicillin because they are allergic to it.

How to avoid this?

First, tell your doctor or pharmacist about your allergies and avoid using these medicines.

Second, pay attention to your body's reactions after taking the medicine, and seek medical attention promptly if any adverse symptoms occur.

Something you didn't notice

Drug toxicity

After reading the above, everyone should have a clear idea in their mind. As long as we follow the doctor's advice and read the instructions, we can avoid most of the "poisons", but some are more hidden.

1. Be careful of "poisoning" when taking multiple drugs at the same time

For example, if you want to get better from a cold quickly, you can take this medicine and that medicine as a supplement. It's okay to take both medicines strictly according to the instructions, right?

This is really a problem. In fact, these two drugs may contain the same ingredient, or one of them may enhance the effect of the other, thus causing artificial "poisoning".

This situation can obviously be avoided.

2. Drugs that have gone bad or expired may be toxic

Before taking medicine, check the medicine packaging to see if it is complete and within the shelf life.

Among adverse drug events, some are caused by improper storage of drugs, such as taking spoiled or expired drugs.

Don’t take these medicines, otherwise you will create opportunities for yourself to be “poisoned”.

Adverse drug reactions

what to do?

No matter what type of adverse reaction it is, if it occurs, don't rush.

1. Observe and see the severity of adverse reactions

If the reaction is minor, such as stomach pain and nausea, that occurs within half an hour of taking the medicine, you do not need to stop taking the medicine if it subsides after a while.

2. Seek medical attention promptly

If you develop a rash that does not go away, severe headache, blurred vision, or difficulty breathing, do not hesitate to seek medical attention immediately.

Especially if you find purple patches on your body, you may have a severe allergic reaction and should seek medical attention immediately.

I feel something is wrong after taking the medicine

It must be very harmful?

The above mainly talks about irrational use of drugs and "poisoning" under special circumstances. In addition to these, the more common is "poisoning" under rational use of drugs, that is, the side effects of drugs.

After taking the medicine, your body may feel "something is not right", some of which you may feel but some you may not.

1. Wide-ranging impact, harming innocent people

Because reasonable use of drugs can also produce side effects, but this does not mean that the drugs "hurt" your body. Rather, when the drugs are exerting their effects, they are not highly targeted and have a wider impact area, thus involving some other organs.

But we have to believe in the safety tests that are done before every drug is put on the market. These side effects on other organs have been verified through multiple experiments and proven to be tolerable.

Then you might ask, wouldn’t it be better to use more targeted drugs?

In theory, yes, but not necessarily in practice.

On the one hand, because humans have limited time and experience in drug development, some highly targeted drugs developed in the later stages have not been in clinical use for a long time and require more observation;

On the other hand, even if a drug is highly targeted at a certain disease or symptom, it does not necessarily mean that the side effects of the drug on the human body will be smaller.

2. Long-lasting effect, still in effect

For some drugs, you may not feel the effects immediately, but when you wake up the next day, you may feel something is wrong. This is the "aftereffect" of the drug.

For example, some sedatives and hypnotic drugs may make you feel weak and sleepy when you wake up the next day.

But don't worry, this is not a brain injury, it's just that some drug residues in the body are still taking effect.

Once a drug is stopped, it is usually excreted from the body slowly.

Drugs that are metabolized quickly will be excreted quickly; even drugs that are metabolized slowly will basically be excreted in about three days, so don't worry about it "poisoning" you.
