Reports of abnormal vision were rare; it occurred in less than 0.1% of patients using tadalafil. The risk of heart attack or abnormal heart rhythms during sex is higher in men with unstable angina (angina that occurs at rest or with minimal exertion), poorly controlled hypertension, moderate to severe heart failure, moderate to severe disease of the heart valves, recent heart attack (less than two weeks previously), potentially life-threatening disorders of heart rhythm such as recurrent ventricular tachycardia, and moderate to severe disease of the heart muscles. In these men, doctors usually stabilize or treat the heart conditions before prescribing sildenafil. When Should I Call My Doctor About Sexual Dysfunction?

The search for an erectile dysfunction panacea has been on for years, with other researchers targeting nitric oxide as well. Erectile dysfunction, heart disease and other vascular diseases: Certain risk factors increase the risk of more atheroma forming which can make atheroma-related conditions worse. These are discussed in more detail in another leaflet called 'Preventing Cardiovascular Diseases'. Briefly, risk factors that can be modified and may help to prevent atheroma-related conditions from getting worse are: Smoking. Smoking is one of the biggest risk factors for developing an atheroma-related condition. Smoking roughly doubles your chance of developing ED. Young smokers may not be aware that they have a much greater risk of developing ED by middle age compared with nonsmokers. If you smoke, make every effort to stop. High blood pressure. Make sure your blood pressure is checked at least once a year. If it is high, it can be treated. If you are overweight, losing some weight is advised. A high cholesterol. This can be treated if it is high. Inactivity. We should all aim to do some moderate physical activity on most days of the week for at least 30 minutes. For example, brisk walking, swimming, cycling, dancing, gardening, etc. Diet. Aim to eat a healthy diet. Details in a separate leaflet called 'Healthy Eating'. Alcohol excess. Diabetes. If you have diabetes, good control of the blood sugar level and blood pressure can help to minimise the impact of diabetes on the blood vessels. buy levitra from canada viagra purchase online viagra

Sildenafil (Viagra) was the first oral phosphodiesterase type 5 (PDE5) inhibitor approved by the FDA in the United States for the treatment of erectile dysfunction (it is not approved for women). Sildenafil inhibits PDE5, which is an enzyme that destroys cGMP. By inhibiting the destruction of cGMP by PDE5, sildenafil allows cGMP to accumulate. The cGMP in turn prolongs relaxation of the smooth muscle of the corpora cavernosa. Relaxation of the corpora cavernosa smooth muscle allows blood to flow into the penis resulting in increased engorgement of the penis. In short, sildenafil increases blood flow into the penis and decreases blood flow out of the penis. Can Sexual Problems Be Prevented? While sexual problems cannot be prevented, dealing with the underlying causes of the dysfunction can help you better understand and cope with the problem when it occurs. There are some things you can do to help maintain good sexual function: Follow your doctor's treatment plan for any medical/health conditions. Limit your alcohol intake. Quit smoking. Deal with any emotional or psychological issues such as stress, depression, and anxiety. Get treatment as needed. Increase communication with your partner.
