Viagra generally refers to sildenafil, which can dilate the blood vessels of the penis, enhance male erectile function, maintain the penis hard enough, and prolong the time of sexual intercourse. After taking Viagra, the patient may experience symptoms such as penile erection, facial flushing, and increased heartbeat.
However, some people will have side effects after taking Viagra, and may experience headaches, stomach discomfort, and temporary visual changes. Headaches are the most common, which may occur a few hours after use or the next day, and are usually short-lived and mild. Stomach discomfort is caused by drug stimulation, including symptoms such as heartburn, diarrhea, and stomach pain. In addition, vascular dilation can cause visual changes such as blurred vision, color vision changes, and narrowed visual field.
It should be noted that while taking Viagra, you cannot take nitroglycerin drugs at the same time, and taking them together may cause accidents. Therefore, try to eat less of this type of drugs in normal times, and drink more water after taking the medicine to promote metabolism. Eat more vegetables and fruits on a daily basis, eat less spicy and irritating foods, ban smoking and limit alcohol, participate in more outdoor sports, and reduce psychological pressure.
