What is the most important information I should know about
tadalafil? |
|
|
Do not take tadalafil if you are taking any of the following
medicines: |
|
· |
a nitrate such as nitroglycerin (Nitrostat, Nitrolingual, Nitro-Dur,
Nitro-Bid, Minitran, Deponit, Transderm-Nitro, others), isosorbide dinitrate
(Dilatrate-SR, Isordil, Sorbitrate), isosorbide mononitrate (Imdur, ISMO,
Monoket), and others; |
|
· |
nitrates are also found in some recreational drugs such as amyl nitrate or
nitrite ("poppers"); or |
|
· |
an alpha blocker (other than tamsulosin (Flomax) 0.4 mg once a day) such as
doxazosin (Cardura), guanadrel (Hylorel), prazosin (Minipress), terazosin
(Hytrin), alfuzosin (Uroxatral), and others. |
|
|
Taking tadalafil with any of these medications may cause very low blood
pressure, possibly resulting in dizziness, fainting, stroke, or heart
attack. |
|
|
Contact your doctor or seek emergency medical attention for any erection
that lasts longer than 4 hours. A sustained erection can damage the
penis. |
|
|
Refrain from further sexual activity and notify your doctor it you develop
dizziness, nausea, or angina (pain, tightness, discomfort, numbness, or tingling
in the chest, arms, neck, or jaw) during sexual
activity. |
|
|
Tadalafil is usually taken when needed before sexual activity. The effects
of tadalafil may last for up to 36 hours or more. Your doctor will determine how
often you can take tadalafil. Do not take tadalafil more often than is directed
by your doctor. |
|
|
Tadalafil relaxes muscles within the penis. This allows increased blood flow
into the penis, necessary to achieve and maintain an
erection. |
|
|
Tadalafil is used to treat erectile dysfunction
(impotence). |
|
|
Tadalafil may also be used for purposes other than those listed in this
medication guide. |
