What is the constitution of people with carsickness? In case of carsickness, choose the appropriate carsickness medicine

. In fact, carsickness may be related to poor self balance. The balance of human body is affected by three systems, namely vestibular system, visual system and proprioceptive system. The vestibular system is the most important system. Vestibular organs are located in the inner ear, including elliptical sac, balloon and semicircular canal. Balloon and elliptical sac are responsible for the stimulation of linear motion, and semicircular canal is responsible for the rotational motion of human body.

when the current court function is strongly stimulated, there will be carsickness, airsickness and motion sickness, and then nausea, vomiting, pale face, etc. The study found that women have a higher probability of carsickness and worse vestibular function than men. Some people’s motion sickness is not affected by vestibular function, which mainly includes emotional instability, hunger and satiety, poor sleep, driver’s sudden braking, turbulence, lack of air circulation in the car and other factors.

to prevent carsickness, attention should be paid to stabilizing mood, eating but hungry and full, ensuring adequate sleep, etc. If necessary, you can reasonably choose the medicine for carsickness and follow the doctor’s advice to choose the medicine suitable for you; According to the length of driving time, choose oral carsickness medicine or carsickness paste, etc. When carsickness occurs, pay attention to ventilation and drink some water appropriately. Pressing Neiguan point can also alleviate the symptoms of carsickness. Neiguan point is located 2 inches above the transverse line of the wrist in the middle of the palm of the forearm, between the long metacarpal tendon and the radial wrist flexor tendon.

In case of carsickness, how to choose the appropriate carsickness medicine?

1. Why did I take carsickness medicine without effect?

1. Improper choice of drugs

some people with motion sickness take drugs that have not been effective, probably because they have not found the kind of motion sickness medicine suitable for themselves. There are several kinds of motion sickness drugs with different components and pharmacological characteristics. You might as well learn about various types of motion sickness drugs and try to change a motion sickness drug, which may solve the problem& nbsp; Commonly used drugs for carsickness include dizziness stopping tablets (chemical name: Difenidol tablets), halogenated Haining (also known as chengyuning, chemical name: diphenhydramine), metoclopramide tablets (chemical name: metoclopramide), morpholine tablets (chemical name: domperidone), fisaille (phenylcyclononyl hydrochloride tablets), scopolamine hydrobromide patches (also known as carsickness patches).

drugs for the prevention and treatment of carsickness have different efficacy durations, some lasting 1 ~ 2 hours, such as Weifuan tablets; Some can last for 4 ~ 5 hours, such as feisaile; Some can last for more than 12 hours, such as carsickness stickers, so appropriate drugs should be selected according to the length of travel time.

2. Improper drug taking methods

. Failure to take the appropriate dose of drugs at the right time or taking other drugs at the same time will affect the effect of motion sickness drugs.

for example, oral carsickness drugs are generally absorbed quickly and can take effect in half an hour to an hour, so they should be taken half an hour to an hour before taking the bus; Carsick stickers are special and slow to absorb, so they should be pasted 5 ~ 6 hours in advance. If they are pasted before getting on the bus, it is often late.

for the sake of insurance, some people take medicine before getting on the bus and take additional medicine arbitrarily after getting on the bus. This is very dangerous! Most carsickness drugs can last for a long time. Overdose will increase the chance of adverse reactions. Drugs can’t & ldquo; Cure dizziness & rdquo;, Maybe & ldquo; Dizziness & rdquo;!

if you are taking other drugs, you must carefully read the instructions before taking motion sickness drugs to see if there is any conflict between drugs. It would be better if you can consult a pharmacist or doctor directly. For example, yunhaining should not be combined with ototoxic drugs, and metoclopramide can increase the toxicity of cold drugs.

in addition, some people take motion sickness drugs, which are sometimes effective and sometimes ineffective. It is likely to be related to their physical state or some unfriendly environmental factors, such as fasting or overeating, fatigue, lack of sleep, air pollution, emotional tension, and special smells such as gasoline and lampblack may promote the occurrence and aggravation of motion sickness. Therefore, these adverse factors should be avoided before taking planes, cars and ships.
