How Generic Cialis Tadalafil works in the body:

The medication comes in the form of pills. Tadalafil (generic Cialis) increases and improves the blood flow throughout the body, specifically blood flow to the penis to enable users to achieve erection up to 36 hours after intake. Tadalafil will not work if there is no sexual stimulation of the penis that is, it will not automatically create an erection. During sexual activity, however, Tadalafil can increase the hardness of your erection as well as the ease of achieving it. Here are some of the important features of Tadalafil:

This means that Tadalafil users enjoy the same benefits as Cialis, including:

  • Effectiveness
  • Duration
  • Prescription requirements
  • Side effects

Food Interactions

Tadalafil may be taken without the need to eat

Alcohol Interactions

Both alcohol and Tadalafil act as mild vasodilators. Tadalafil is a PDE5 inhibitor, so patients should be aware. When these are taken in combination, the effects of lowering the patients blood pressure may be increased. Physicians should inform users that consuming a substantial amount of alcohol at one sitting (defined as five or more drinks) and consume Tadalafil may experience side effects. These include potentially increased orthostatic symptoms - an increase in heart rate, decrease in standing blood pressure, dizziness, and headache.

Warning: Prolonged Erection

Some Tadalafil users have reported prolonged erections greater than 4 hours, although these cases are rare. Reports of priapism, defined as painful erections lasting longer than 6 hours, have been rarely reported. If priapism is not treated promptly, it can result in damages to erectile tissue. Those who experience an erection lasting more than 4 hours, whether or not it is painful, should seek immediate medical attention.

Some patients with preexisting conditions should take caution when using Tadalafil. These include those who stand a greater risk of priapism (including conditions like sickle cell anemia, multiple myeloma, or leukemia) or those who have an anatomical deformation of the penis (such as angulation, cavernosal fibrosis, or Peyronies disease).

Cardiovascular precautions

Due to the cardiac risk during sexual activity, physicians should evaluate the patients cardiovascular status, to ensure that they are healthy enough for sexual activity. Erectile dysfunction treatment, including Tadalafil, should not be used for men who have been advised to refrain from sexual activity. Those who experience cardiovascular symptoms upon starting sexual activity should cease immediately and seek immediate medical attention.


4.1 Nitrates

Any patient consuming any form of organic nitrites are contraindicated, whether regularly or intermittently. In lab tests, tadalafil demonstrated an increase in the hypotensive effect of nitrates [see Clinical Pharmacology (12.2)].

4.2 Hypersensitivity Reactions

Those with serious hypersensitivity to tadalafil are contraindicated. Reactions include Stevens-Johnson syndrome and exfoliative dermatitis [see Adverse Reactions (6.2)].

4.3 Concomitant Guanylate Cyclase (GC) Stimulators

Patients who are using a GC stimulant, including a riociguat, should not use tadalafil. Those using PDE5 inhibitors may experience increasing hypotensive symptoms.

Tadalafil has been studied in 22 clinical trials, studying the efficacy and safety of the medication. These trial have lasted up to 24 weeks and included over 4000 patients. When taken as indicated, once per day, tadalafil demonstrated effectiveness in improving erectile dysfunction o=in men.

7 randomized, multicenter, double-blinded, placebo-controlled, parallel-arm design, primary efficacy and safety studies of Tadalafil were given to the general population. Two occurred in the United States, and 5 in centers outside of the country. ED patients with diabetes mellitus and those who developed ED status after a bilateral nerve-sparing radical prostatectomy were studied in a separate, additional efficacy and safety test.

In the initial 7 trials, tadalafil was taken according to the recommended doses, from 2.5 mg up to 20 mg, once per day. Participants were allowed to choose when to begin sexual activity in the time interval after their dosing. There were no restrictions on food or alcohol intake.

Study Results

Patients with diabetes mellitus were shown to have success taking tadalafil. Diabetics were included in all 7 initial tests of the ED population (N=235). They were also included in a separate study specifically measuring tadalafil in ED patients with both Type 1 and Type 2 diabetes (N=216). This was a randomized, placebo-controlled, double-blinded, parallel-arm design prospective trial. Tadalafil demonstrated clinically measurable and statistically indicated improvement in erectile function, using the EF domain measurement of the IIEF questionnaire and Questions 2 and 3 of the SEP diary.

Important Patient Information


IMPORTANT: HOW TO USE THIS INFORMATION: This is a summary and does NOT have all possible information about this product.

Always ask your health care professional for complete information about this product and your specific health needs.

USES: Tadalafil is used to treat male sexual function problems (impotence or erectile dysfunction-ED). In combination with sexual stimulation, tadalafil works by increasing blood flow to the penis to help a man get and keep an erection. Tadalafil is also used to treat the symptoms of an enlarged prostate (benign prostatic hyperplasia-BPH). It helps to relieve symptoms of BPH such as difficulty in beginning the flow of urine, weak stream, and the need to urinate often or urgently (including during the middle of the night). Tadalafil is thought to work by relaxing the smooth muscle in the prostate and bladder. This drug does not protect against sexually transmitted diseases (such as HIV, hepatitis B, gonorrhea, syphilis). Practice "safe sex" such as using latex condoms. Consult your doctor or pharmacist for more details.

HOW TO USE: Read the Patient Information Leaflet if available from your pharmacist before you start taking tadalafil and each time you get a refill. If you have any questions, ask your doctor or pharmacist. Take this medication by mouth, with or without food, as directed by your doctor. Do not take tadalafil more often than once daily.

Follow your doctor's directions on how to take this medication. The dosage is based on your medical condition, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). To treat the symptoms of BPH, take this medication as directed by your doctor, usually once a day. If you are also taking finasteride with this medication to treat symptoms of BPH, talk with your doctor about how long you should continue taking this medication. To treat erectile dysfunction-ED, there are 2 ways that tadalafil may be prescribed. Your doctor will determine which is the best way for you to take tadalafil. Follow your doctor's directions exactly since your dosage depends on how you are taking it. The first way is to take it as needed, usually at least 30 minutes before sexual activity. Tadalafil's effect on sexual ability may last up to 36 hours. The second way to treat ED is to take tadalafil regularly, once a day every day. If you take it this way, you may attempt sexual activity at any time between your doses. If you are taking tadalafil to treat both ED and BPH, take it as directed by your doctor, usually once a day. You may attempt sexual activity at any time between your doses. If you are taking tadalafil once daily for BPH, or for ED, or for both, take it regularly to get the most benefit from it. To help you remember, take it at the same time each day. Tell your doctor if your condition does not improve or if it worsens.

SIDE EFFECTS: Headache, stomach upset, back pain, muscle pain, stuffy nose, flushing, or dizziness may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

Tadalafil can cause a serious drop in your blood pressure when used with nitrates, which can lead to dizziness, fainting, and rarely heart attack or stroke. Do not use any of the following with tadalafil or within 48 hours of your last dose of tadalafil: certain drugs used to treat chest pain/angina (nitrates such as nitroglycerin, isosorbide), recreational drugs called "poppers" containing amyl or butyl nitrite. If you are also taking an alpha blocker medication (such as doxazosin, tamsulosin) to treat an enlarged prostate/BPH or high blood pressure, your blood pressure may get too low which can lead to dizziness or fainting. Your doctor may start treatment with a lower dose of tadalafil or adjust your alpha blocker medication to minimize your risk of low blood pressure. Other medications can affect the removal of tadalafil from your body, which may affect how tadalafil works.
