What is Cialis and why is it prescribed? Cialis relaxes muscles within the penis. This allows increased blood flow into the penis, necessary to achieve and maintain an erection. Cialis is used to treat erectile dysfunction (impotence). Do not take Cialis 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 Cialis 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. Cialis is usually taken when needed before sexual activity. The effects of Cialis may last for up to 36 hours or more. Your doctor will determine how often you can take Cialis. Do not take Cialis more often than is directed by your doctor. How should you take Cialis? Follow your doctors directions for taking Cialis. Take each dose with a full glass of water. Cialis is usually taken when needed before sexual activity. The effects of Cialis may last for up to 36 hours or more. Your doctor will determine how often you can take Cialis. Do not take Cialis more often than is directed by your doctor. Cialis can help achieve an erection when sexual stimulation occurs. An erection will not occur just by taking a pill. Cialis can be taken with or without food. Cialis should not be taken with excessive amounts of alcohol (e.g. 5 or more drinks). Excessive alcohol may increase the risk of headache, dizziness, increased heart rate, or low blood pressure when Cialis is taken. If you develop dizziness, nausea, or angina (pain, tightness, discomfort, numbness, or tingling in the chest, arms, neck, or jaw) during sexual activity, refrain from further sexual activity and notify your doctor. Contact your doctor or seek emergency medical attention for any erection that lasts longer than 4 hours. A sustained erection can damage the penis. Grapefruit and grapefruit juice may interact with Cialis. The interaction could lead to potentially adverse effects. You should discuss the use of grapefruit and grapefruit juice with your doctor. Do not increase or decrease the amount of grapefruit products in your diet without first talking to your doctor. Cialis is used as needed, so you are not likely to miss a dose. Store Cialis at room temperature away from moisture and heat. Are there any Cialis side effects? Cialis side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. More common Cialis side effects may include headache, indigestion, back pain, muscle aches, flushing, stuffy or runny nose, and temporary blue tint in vision or difficulty telling the difference between the colors blue and green (uncommon). Less common to rare Cialis side effects may include an allergic reaction (difficulty breathing; closing of the throat; swelling of the lips, tongue, or face; or hives), chest pain or irregular heartbeats, dizziness, nausea, or angina (pain, tightness, discomfort, numbness, or tingling in the chest, arms, neck, or jaw), swelling of the ankles or legs, shortness of breath, prolonged or severe dizziness, and a prolonged (lasting longer than 4 hours) or painful erection. What are the possible food and drug interactions when taking Cialis? If Cialis is taken with certain other drugs, the effects of either could be increased, decreased, or altered. Be sure to inform your doctor of all the prescription and over the counter medications you are taking. Do not take Cialis 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.
