  1. If you feel obvious chest tightness, such as heavy objects pressing on your chest or chest pain, sit down and rest first to avoid dizziness due to a drop in blood pressure after taking the medicine, which may lead to falls and injuries. Then hold a sublingual tablet under the tongue (do not chew it) or swallow) and allow the tablet to dissolve on its own.

  3. If symptoms are not significantly relieved, wait five minutes before taking the third tablet.
  4. If you still feel very uncomfortable after taking 3 tablets, it means that the coronary arteries are seriously blocked and you should call 999 for medical treatment immediately.

Can nitroglycerin be given to others?

Of course not! Since it is impossible to know for sure whether other people’s discomfort symptoms are caused by insufficient coronary blood flow, even though the emergency rescue effect of nitroglycerin sublingual tablets is very significant, it is still mainly aimed at patients with coronary heart disease and myocardial infarction. Rush administration may cause the patient’s condition deterioration.

Not only that, but nitroglycerin is not a “common medication” or a “life-saving miracle drug” that everyone should prepare. Nitroglycerin is a prescription drug, and it is generally only patients with a history of coronary heart disease who need to be prescribed sublingual tablets according to the doctor’s judgment to prevent angina attacks.

The risk of using drugs without authorization lies in whether the “self-interpretation of symptoms” is correct? When angina pectoris attacks, most people complain of chest pain and chest tightness. However, what is considered “chest pain or chest tightness caused by coronary heart disease” cannot be determined by a single symptom. If you feel heart discomfort and want to take sublingual tablets, I am afraid it will increase unnecessary risks.

For example, if you rush to take sublingual tablets when you have low blood pressure, the blood vessels will rapidly expand, causing the patient’s blood pressure to further drop, leading to fainting (fainting) or shock.

Therefore, nitroglycerin drugs should not be provided to anyone by themselves, or purchased and taken by themselves without diagnosis, causing irreparable regrets!
