    Cialis (tadalafil) Dosage and Side Effects

    CIALIS is a prescription drug used for treatment of erectile dysfunction (ED) in men and the signs and symptoms of benign prostatic hyperplasia (BPH). You can buy Cialis online through a registered pharmacy. 

    Proper Use of this medication

    This medicine has been prescribed for you personally and you should not pass it on to others. It may harm them, even if their symptoms are the same as yours.

    Usual dose:

    How to Take CIALIS:

    Always take CIALIS exactly as your doctor has instructed you. You should check with your doctor or pharmacist if you are unsure. Do not take a higher dose than the one which your doctor prescribed for you.

    CIALIS tablets are for oral use. Swallow the tablet whole, with some water.

    You may take CIALIS with or without food.

    Alcohol consumption may decrease the ability to attain an erection and may also temporarily decrease blood pressure.

    There are two different ways of taking CIALIS tablets to treat ED: a 20 mg On-Demand dose taken as needed, or a lower 5 mg daily dose. It may take up to up 5 days for CIALIS Once-a-Day to reach steady blood levels.

    For patients with ED:

    • Try sex at different times to find out what works best for you and your partner.

    • CIALIS works only if you are sexually stimulated.

    • If you don't get the results you expect—talk to your doctor or pharmacist.

    CIALIS for “On-Demand” Dosing:

    The recommended dose is one tablet (20 mg) before sexual activity, as needed. You should NOT take more than the prescribed dose of one CIALIS 10 mg or 20 mg tablet per day. The 10 mg and 20 mg doses are not recommended for continuous daily use.

    You can engage in sexual activity within 30 minutes of taking the tablet and up to 36 hours later. The amount of time CIALIS takes to work varies from person to person.

    CIALIS for Once-a-Day Use:

    Treatment of ED: Your doctor may recommend that you take one tablet of CIALIS (5 mg or 2.5 mg) Once-a-Day every day, at approximately the same time each day, regardless of when you are planning to have sex.

    Treatment of BPH and ED/BPH: Your doctor may recommend that you take one tablet of CIALIS 5 mg Once-a-Day every day, at approximately the same time each day.

    Overdose:

    If you have taken more CIALIS than you should, contact your doctor or a Poison Control Centre immediately.

    Side Effects

    Like all medicines, CIALIS can have some side effects. These effects are usually mild to moderate in nature.

    The most common side effects are headache, indigestion, back pain, muscle aches, nasal congestion, facial flushing, dizziness and high blood pressure.

    Uncommon side effects: swelling of the eyelids, eye pain, conjunctival hyperemia (red eyes) and allergic reactions (including skin rashes).

    Rarely, a prolonged and possibly painful erection may occur after taking CIALIS. If you have such an erection which lasts continuously for more than 4 hours, you should contact a doctor immediately. If this is not treated immediately, permanent penile tissue damage and erectile dysfunction may result.

    Sudden decrease or loss of vision has occurred rarely after the use of oral erectile dysfunction medications, including CIALIS. It has not been established whether the loss of vision is related directly to the use of PDE5 inhibitors or other factors. People who have previously experienced a type of vision loss called Non-Arteritic Anterior Ischemic Optic Neuropathy (NAION) may be at an increased risk of reoccurrence of NAION. If you experience reduction or loss of vision in one or both eyes, stop taking CIALIS and call your doctor.

    If you take CIALIS and have chest pain during or after sexual activity, DO NOT use nitrates, and seek immediate medical assistance.

    Warnings and Precautions

    Before taking CIALIS talk to your doctor if you:

    have or had any of the following conditions:

    • Heart disease or previously had a heart attack: Sexual activity carries a possible risk to patients with heart disease because it puts extra strain on your heart. Before you start any treatment for erectile dysfunction, ask your doctor if your heart is healthy enough to handle the extra strain of having sex. If you have chest pains, dizziness or nausea during sex, stop exerting yourself and tell your doctor you have had this problem.

    • Stroke.

    • Low blood pressure or uncontrolled high blood pressure.

    • Liver or kidney problem.

    • Sickle cell anemia (an abnormality of red blood cells), multiple myeloma (cancer of the bone marrow), or leukemia (cancer of the blood cells).

    • Peptic ulcer or other bleeding disorders.

    • Deformation of the penis.

    • Ever had severe loss of vision, including a condition called Non-Arteritic Ischemic Optic Neuropathy (NAION). The specific type of vision decrease or loss known as NAION has been reported rarely after the intake of CIALIS or other PDE5 inhibitors. Vision decrease or loss may be partial or complete, in one or very occasionally in both eyes. While in some cases the condition may improve over time, it can also be irreversible. If you are taking CIALIS and experience temporary or permanent loss or change in vision, stop taking CIALIS and call your doctor.

    • Hearing problems: Sudden decrease or loss of hearing has been reported with the use of PDE5 inhibitors, including CIALIS, although it is not known if it is due to drug or other factors.

    • Lactose or milk sugar intolerance: CIALIS contains a small amount of lactose (about 250 mg).

    • CIALIS is not recommended to be used in combination with alpha-blockers if you have symptoms of BPH.

    • CIALIS does not protect against sexually transmitted diseases including HIV/AIDS.

    • Long-term studies have shown that CIALIS therapy may decrease sperm concentration in some men. The effect on fertility in men is unknown.

    • CIALIS is not intended for use by women or by children under 18 years of age.

    When CIALIS is used for the treatment of erectile dysfunction, diarrhea was reported more frequently in patients 65 years of age and older (2.5% of patients).

    Only your doctor can decide if CIALIS is right for you. If you have ED, you will need to have a physical examination to diagnose your erectile dysfunction and to find out if you can take CIALIS alone or with your other medicines. If you have urinary problems, you will need to have a physical examination to diagnose your BPH and not a more serious condition such as prostate cancer.
