In summer, some people’s blood pressure rises and some people drop. How to adjust antihypertensive drugs, can they stop?

The blood pressure of many friends has fluctuated recently. Most people have low blood pressure, and a few people have high blood pressure. The person with low blood pressure asked Hua Zi how to adjust the antihypertensive drugs. If the blood pressure is still low, can the drug be stopped?

Those with elevated blood pressure are worried. Blood pressure still rises in summer. Will it be even higher in autumn and winter? Should we increase the dose of medicine now? Hua Zi told them that it was necessary to carefully analyze the reasons to decide whether the drug should be adjusted.

One, blood pressure changes in summer

For most hypertensive patients, blood pressure fluctuates with a pattern of “high in winter and low in summer”. There are two main reasons for the decrease of blood pressure in summer. One is that the human body expands blood vessels on the surface of the body in order to increase heat dissipation; the other is that the amount of sweat of the human body increases in summer, and a large amount of sodium ions are excreted with sweat, which makes blood volume with reduced sodium ion levels.

However, some people with high blood pressure may have elevated blood pressure, because summer days are short and nights are hot, which can shorten sleep time and make people prone to irritability. Lack of sleep and irritability can increase blood pressure. Studies have also shown that during the summer many people’s blood pressure drops during the day and rises at night.

2. Medication adjustment when blood pressure is lowered

1. What kind of blood pressure should be adjusted with medication: The ideal blood pressure of the human body is 120/80mmHg. During antihypertensive treatment, the ideal blood pressure should be used as the control target as much as possible. . Moreover, lower blood pressure has a stronger protective effect on the heart, brain, kidney and other organs. Generally speaking, drug adjustment is recommended when the high pressure is lower than 110mmHg and the low pressure is lower than 60mmHg; or when there are symptoms of insufficient blood supply such as dizziness, palpitations, chest tightness, etc..

2. Attention when adjusting antihypertensive drugs: To adjust antihypertensive drugs, reduce the dosage first and then reduce the types of drugs. Read the drug insert carefully and reduce the drug gradually to the minimum therapeutic dose recommended on the insert.

After reaching the minimum therapeutic dose, if blood pressure is still low and multiple antihypertensive drugs are used in combination, the drug regimen contains diuretics (such as hydrochlorothiazide, indapamide, etc.) , can be used as the first type of drug to be eliminated, because the effect of diuretics on sodium excretion and drainage is similar to the mechanism of increased sweating in summer.

Pulli and sartan have milder effects and milder adverse reactions, and can be used as the second type to be eliminated; dipines may cause cardiac arrhythmias in the early stage of application Overspeed, headache, facial flushing and other adverse reactions, but will disappear with continuous application. In order to avoid the initial adverse reactions, dipine drugs are placed in the third place to reduce.

Lol drugs may have a “rebound phenomenon” when the dose is reduced or stopped, which will cause a sudden rise in blood pressure and tachycardia, and induce cardiovascular events, so a longer period of time is required. The drug withdrawal period (not less than two weeks), the risk of short-term drug withdrawal is high, and for patients with heart disease, the use of lorol drugs is not only for blood pressure, but also to improve the prognosis of the disease, so it is not recommended Withdrawal.

This order of drug withdrawal is only a reference. Each patient’s situation is different, and the reaction after the drug is different. The actual treatment should be adjusted under the guidance of a doctor.

3. Try not to stop the drug completely: Hypertension is an incurable chronic disease that requires continuous drug control. Although blood pressure is normal or low in summer, it is also achieved under the action of antihypertensive drugs. Complete withdrawal of drugs may cause blood pressure to rebound rapidly, which will increase the risk of cardiovascular and cerebrovascular diseases.

If the drug is completely stopped, it will be necessary to retake it when blood pressure rises in autumn and winter, and most adverse reactions of antihypertensive drugs occur in the early stage of medication. Medication risk. Therefore, the dose of antihypertensive drugs can be reduced according to the blood pressure, but it is not recommended to stop the drug completely.

Third, whether to take medicine when blood pressure rises

Raising blood pressure during the summer is less common, but some people may experience elevated blood pressure. It may be the progression of hypertension itself, or it may be the increase of blood pressure caused by lack of sleep and bad mood. So don’t rush to add medicine if your blood pressure rises in summer, you can observe it for a week or two to assess your own situation.

If it is the cause of lack of sleep and bad mood, blood pressure can return to normal after correction; in severe cases, you can also seek help from a psychiatrist and use sedative and hypnotic drugs for auxiliary treatment. If high blood pressure has progressed, it is necessary to increase the dose of the drug under the guidance of a doctor.

To sum up, blood pressure is prone to changes in summer, and medicines need to be adjusted according to the blood pressure. For those with low blood pressure, it is not recommended to stop taking antihypertensive drugs completely. The dose and types of drugs can be reduced, and the treatment can be maintained at the lowest dose. However, if the antihypertensive drug is reduced to the lowest dose, and symptoms of hypotension still occur, the drug can also be completely discontinued. People with high blood pressure need to find the cause first and then treat it.

Medication adjustment needs to be carried out under the guidance of a doctor. If you have any doubts about the medicine, please consult your doctor or pharmacist. I am Huazi, a pharmacist. Welcome to follow me and share more health knowledge.
