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.
What is tadalafil?

How do brand-name drugs and generics differ?
When scientists develop a new drug, they give it a generic name reflecting its chemical makeup. Once the Food and Drug Administration (FDA) approves the drug, the manufacturer markets it with a brand or trade name, which is usually shorter and easier to remember. A drug company can hold exclusive patent rights to make a drug for 20 years after its discovery. After that, other companies can start making generic versions of the drug.
In almost all cases, generics work as well as their brand-name siblings, and often cost considerably less. This is possible not because of lower quality, but because research and advertising costs are much less for generics.
