good night doc.
Thank you for the question.
Erectile dysfunction (impotence) is defined as a condition in which the penis cannot start or maintain an erection even though it has been sexually stimulated. This condition most often arises due to psychological disorders, such as when your husband is stressed, feels insecure, feels guilty, has problems at work, is exhausted, is anxious or fears excessive, and so on. Unhealthy lifestyles, such as lazy exercise, smoking or consuming alcohol, abusing drugs, irregular sleep, and so on can also cause erectile dysfunction. In rare cases, erectile dysfunction can also occur associated with a disease, such as diabetes, thyroid gland disorders, heart problems, strokes, hypertension, Peyronie's disease, multiple sclerosis, nerve nerves, and so on.
In most cases, erectile dysfunction is only temporary and will improve over time. Therefore, do not be hasty in giving your husband medicine. The drug that you mentioned contains the active composition of sildenafil which does not belong to the class of over-the-counter drugs, so it is unethical if we describe in detail the procedures for its use in free forums like this.
It's best if you first establish good communication with your husband regarding the complaint. If there are certain problems that he is facing, help him to calm down, give him advice the best solution in overcoming the problem, do not hesitate to be a good listener so that he does not stress. Not only that, you also need to accompany your husband to live a healthy lifestyle, stop smoking, do not consume any drugs or alcohol, sleep early and regularly, exercise for at least 30 minutes every day, enrich the intake of antioxidants in your food and drinks, maintain weight to stay ideal, and manage stress wisely.
If with this effort the condition has not improved, your husband can check his complaints directly to the doctor or urology surgeon. It's just that, considering that currently outbreaks of COVID-19, examinations for non-emergency cases, including those of your husband, should be postponed until the outbreak has subsided.
Hope this helps ...
