What should I do if I experience dizziness and tachycardia after taking antihypertensive drugs?

A friend left a message for Huazi, saying that after taking antihypertensive drugs, his heart rate reached 120 and he felt dizzy. Was it because of the drugs? Should he continue to take the drugs? He told Huazi that he was taking three kinds of antihypertensive drugs, namely diazepam, sartan, and diuretics. He had been taking diazepam, but his blood pressure was unstable recently, so he added sartan and diuretics.

Huazi told him that dizziness and tachycardia were probably adverse reactions caused by excessive doses of antihypertensive drugs, which caused blood pressure to drop too quickly. It was not recommended to stop taking the drugs, but the dosage could be reduced appropriately.

1. The blood pressure reduction process should be stable

Many patients with hypertension, after discovering that their blood pressure is high, will be particularly eager to lower their blood pressure to normal. This idea is understandable, but the blood pressure reduction process cannot be rushed.

The human body has a good tolerance to high blood pressure. If blood pressure is elevated for a long time, the body will gradually adapt to the state of higher blood pressure and will not feel uncomfortable. However, if the blood pressure drops too quickly at this time, it will activate neural feedback regulation and cause reflex tachycardia.

Dihydrotestosterone-type antihypertensive drugs have a significant effect on vasodilation, so tachycardia is an adverse reaction that is easy to occur after taking the drugs. Moreover, after the cerebral artery dilates, it may cause compression on the peripheral nerves, causing adverse reactions such as dizziness, headache, and facial flushing. Therefore, when using dihydrotestosterone-type drugs, it is recommended to start with a small dose, increase the dose slowly, and steadily lower blood pressure.

Although that friend had already adapted to the effects of dihydrotestosterone drugs, the addition of sartan and diuretics produced a synergistic antihypertensive effect with the original dihydrotestosterone drugs, which may have caused blood pressure to drop too quickly, thus causing tachycardia problems.

Second, most people's adverse reactions are temporary

Although dihydrotestosterone has the adverse reaction of causing tachycardia, most people's bodies will adapt to lower blood pressure as they continue to take the medicine, and the symptoms of tachycardia will be alleviated and subsided. When using dihydrotestosterone for the first time or when adjusting the medicine, the method of administering small doses and gradually increasing the dose can reduce or avoid the occurrence of adverse reactions.

Elderly patients with hypertension usually have arterial stenosis and hardening. If blood pressure drops too quickly, it will affect the blood supply to the heart and brain, and even have the risk of inducing cardiovascular and cerebrovascular diseases. Therefore, for elderly patients with hypertension, it may take several months to slowly increase the dosage of the drug to lower blood pressure.

3. Combination with Lolamine drugs can reduce tachycardia

If you have heart disease or coronary heart disease, you can consider using it in combination with dihydrotestosterone drugs. Dihydrotestosterone drugs can selectively inhibit the β1 receptors on the heart, reduce cardiac excitability, and slow down the heart rate. They can offset the tachycardia caused by dihydrotestosterone drugs and have a good protective effect on the cardiovascular system.

Lol drugs can significantly reduce myocardial oxygen consumption and reduce the frequency and severity of angina pectoris in patients with coronary heart disease. However, it should be noted that Lol drugs are not suitable for people with conduction block and slow heart rate.

There are overlaps in the pharmacological mechanisms of lol drugs, "pril" and "sartan"; lol drugs and diuretics will interfere with sugar and lipid metabolism, so lol drugs should be used with caution when used in combination with pril, sartan and diuretics.

In summary, after taking antihypertensive drugs, the symptoms of tachycardia and dizziness are likely due to the reflex increase in heart rate caused by the rapid blood pressure reduction, which is more likely to occur when using dihydropyridine drugs. However, most of these situations are temporary and can be alleviated or disappeared after continuous medication. By taking small doses and gradually increasing the dose, the occurrence of adverse reactions can be reduced.

Drugs must be used under the guidance of a doctor. If you have any questions about medication, please consult a doctor or pharmacist. I am pharmacist Huazi, welcome to follow me and share more health knowledge.
