viagra cialis online pharmacy pharmacy is the third erectile drug officially approved for sales in the United State. The first two drugs was Viagra and Levitra, scientifically know as sildenafil citrate and vardenafil. The FDA (Food and Drug Administration) approved the drug for sales in 21st December, 2003.
Tadalafil is an oral drug that is used for treating impotence (the inability to attain or maintain a penile erection). It is in a class of drugs called phosphodiesterase inhibitors that also includes sildenafil (Viagra) and vardenafil (Levitra).
When a man is sexually stimulated, his body's normal response is to increase blood flow to his penis. This results in an erection. Tadalafil helps increase blood flow to the penis and may help men with erectile dysfunction get and keep an erection satisfactory for sexual activity. Once a man has completed sexual activity, blood flow to his penis decreases, and his erection goes away.
How should this medication be used?
Tadalafil comes as a tablet to take by mouth. It may be taken with or without food.
There are two different ways to take tadalafil. Talk to your doctor about which dosing schedule is right for you. It is sometimes taken as needed before sexual activity, not more often than once every 24 hours. Your doctor will help you decide the best time for you to take tadalafil before sexual activity. Tadalafil is also sometimes taken once a day every day without regard to timing of sexual activity. You may attempt sexual activity at any time between doses. If you are taking tadalafil on a regular schedule, take it at around the same time every day. If you have certain health conditions or are taking certain medications, your doctor may tell you to take tadalafil less often or may prescribe a lower dose to be taken once a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take tadalafil exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
What happens if I miss a dose?
Since tadalafil is used as needed, you are not likely to be on a dosing schedule.
If you take tadalafil every day and you miss a dose, take the missed dose as soon as you remember. If it is almost time for your next dose, wait until then to take the medicine and skip the missed dose. Do not take extra medicine to make up the missed dose.
