The most common form of medications available are known as PDE5 inhibitors. This class of medications work by increasing blood flow to penile tissues and are effective for over 80% of patients.
Some possible side effects can include a headache, nasal stuffiness, feeling flushed, and slight muscle ache.
If you have heart disease and are taking a class of drug called nitrates, you will be advised by the doctor not to take them concurrently as this can potentially cause a significant drop in blood pressure.
It is also dangerous to mix the blue pills and alkyl nitrites together.
Please also inform your doctor about any other medications you are taking, including over the counter medications or herbal supplements. – Erectile Dysfunction Clinic Singapore / Erectile Dysfunction Treatment Singapore / ED Treatment Singapore
