👩🏽⚕️ Additional questions (FAQs)
💬 What are Nitroglycerin / Nitrostat sublingual tablets/sprays used for?
This is a 'God-given', extremely powerful, immediate-acting (Vasodilator) medicine to save the lives of heart patients! When the blood flow to the heart decreases and the chest suddenly tightens and the unbearable pain of 'Heart Attack/Angina (Angina Pectoris)' spreads down the throat/arm, this pill, placed under the tongue, stops the pain 100% in 2 minutes and saves lives.
💬 When you're about to die from chest pain (Angina), how can you save your heart with this little pill (Nitroglycerin)?
A heart attack occurs when a blood vessel in the heart becomes blocked/narrowed and the heart does not get enough blood/oxygen! When this pill is placed under the tongue, it is absorbed into the blood and turns into a gas called 'Nitric Oxide (NO)' inside the body. That gas instantly relaxes all the blood vessels in our heart and body and makes them fat/large (Rapid Vasodilation). Then, blood flows through the block and into the heart, and the patient's chest pain disappears immediately.
💬 What is the fatal danger that people using this pill (Nitrostat) should 'never' do?
The biggest and only rule! If you have taken pills like 'Viagra (Viagra / Sildenafil)' for sexual stimulation, never put this nitroglycerin pill under your tongue for the next 24-48 hours! If you do, all the blood vessels will become too dilated and your blood pressure will drop to zero (Severe Hypotension) and you may go into a coma and die! Also, when you take this pill, you will definitely get a 'Severe Headache (due to the dilation of the blood vessels)'.
