How does Cialis work? What will it do for me?

Tadalafil belongs to a group of medications called phosphodiesterase type 5 inhibitors. It is used to treat erectile dysfunction (male impotence). It helps to achieve and maintain an erection sufficient for sexual activity to occur. It does this by allowing a greater flow of blood into the penis when a man taking the medication is sexually aroused. It works only with sexual stimulation and does not increase sexual desire.

Tadalafil is also used to treat symptoms of benign prostatic hyperplasia (BPH) in men with enlarged prostates. It helps to relieve symptoms such as the frequent need to urinate, painful urination, or the sensation of not completely emptying the bladder. It does this by relaxing muscles in the prostate and bladder.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.

How should I use Cialis?

For the treatment of erectile dysfunction:

On-demand dosing:
The usual recommended dose is 20 mg taken as needed, at least 30 minutes before sexual activity. This medication has been shown to be effective within 30 minutes of taking the tablet, and last up to 36 hours later. As the amount of time tadalafil takes to work varies from person to person, starting sexual activity at different times after taking the tablet will determine the optimal time for sexual activity. The maximum recommended amount of medication to take is one tablet a day.

Once-a-day use:
The usual recommended dose is 5 mg per day, taken at about the same time each day and regardless of when sexual activity is planned. The daily dose may be lowered by your doctor if necessary.

Tadalafil may be taken with or without food.

For the treatment of benign prostatic hyperplastia (BPH):
The usual recommended dose is 5 mg once daily, at about the same time each day. It may be taken with or without food.

Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

It is important to take this medication exactly as prescribed by your doctor. Do not take higher doses of this medication than prescribed by your doctor. Contact your doctor if you take a greater dose of tadalafil than prescribed.

Store this medication at room temperature (between 15°C and 30°C) and keep it out of the reach and sight of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

Who should NOT take Cialis?

Do not take this medication if you:

  • are allergic to tadalafil or any ingredients of this medication
  • have been advised by your doctor not to engage in sexual activity
  • are taking (or have taken in the past 48 hours) any type of nitrate medication in any form (oral, sublingual [under the tongue], skin patch, or spray). Nitrate medications include nitroglycerin and related medicines that are used for the relief of chest pain or angina. They also include amyl nitrite "poppers." Use of these medications with tadalafil could cause a sudden severe drop in blood pressure that could lead to dizziness, fainting, heart attack, or stroke.

Nitrates are found in medications that are used to treat angina (chest pain). If you are not sure if you are taking nitrates, ask your doctor or pharmacist. Nitrates must NOT be taken by anyone who is using tadalafil because they can cause your blood pressure to drop very low. This may cause dizziness, fainting, heart attack, or stroke.
