The Food and Drug Administration (FDA) has issued a public health warning about the effectiveness of tadalafil, the active ingredient in Cialis, to treat erectile dysfunction (ED).
The FDA has determined that Cialis and tadalafil are not safe and effective for treating erectile dysfunction (ED) in men, according to the agency’s most recent guidance. Cialis works by increasing blood flow to the penis, which helps men get and keep an erection. Tadalafil does not treat ED or the underlying cause of the condition.
“We have not received any positive response from these medications to treatment of erectile dysfunction in men,” says Dr. Michael DiNapoli, assistant professor of urology at Tufts University School of Medicine and the lead author of the report. “This is a very serious matter.”
In a study of more than 3,000 men who were treated with tadalafil for erectile dysfunction, diNapoli and his colleagues evaluated the efficacy and safety of tadalafil and other ED medications in more than 200 patients who had been on tadalafil for at least six months. Tadalafil is a PDE5 inhibitor that increases blood flow to the penis when an erection is achieved by using nitric oxide donor cells. Tadalafil does not increase blood flow to the penis or cause a decrease in blood pressure, which is the primary mechanism of tadalafil’s action.
In a separate study, DiNapoli et al. found that the safety of tadalafil in patients with erectile dysfunction was similar to that of other medications, including sildenafil and diltiazem. Tadalafil has been associated with a decrease in blood pressure in some individuals with ED.
“Tadalafil is an effective treatment option for patients who are unable to achieve or maintain an erection due to erectile dysfunction. Tadalafil is a PDE5 inhibitor,” DiNapoli says. “While patients with erectile dysfunction and other ED medications are at an increased risk for cardiovascular complications, tadalafil is not a treatment for ED.”
The FDA’s warning is based on an analysis of more than 30,000 patients who were enrolled in the FDA’s National Long-Term Erectile Dysfunction (LEDE) clinical trial, which assessed the safety and efficacy of tadalafil in over 4,000 patients with ED. In the study, the average age of tadalafil users was 69, with a median of 73 in the tadalafil group, compared with 59 in the placebo group. The patients in the tadalafil group also had more comorbidities, including diabetes and hypertension, and were more likely to have had a heart attack, stroke, or life-threatening condition such as a heart attack or other heart problem.
The FDA warns that tadalafil may cause serious side effects, including vision problems, hearing loss, and prolonged erections, which can lead to vision loss and other vision problems. These side effects are rare and may be reversible with medication.
“Patients who take tadalafil should be monitored closely for these rare side effects, which can be serious, especially when the medication is taken more than four hours before anticipated sexual activity,” the FDA’s warning is based on a review of more than 3,400 patients who were randomized to the drug, who had a diagnosis of ED, or who had other health conditions that may increase the risk for these side effects. “Patients should not take tadalafil without a doctor’s advice and medical supervision,” the FDA warning says.

More serious side effects include:
If you experience any of these side effects, seek medical attention immediately. These are symptoms of a serious adverse reaction to this medication and immediately require treatment.
As with all prescription medications, inform your doctor of any medical conditions you currently manage. Tell them about any and all medications, prescription drugs, and supplements you are taking before starting treatment with Levitra. Levitra can interact with bodily substances, causing potentially serious adverse reactions.
Do not take Levitra if you take nitrate medications such as isosorbide dinitrate, isosorbide mononitrate, and nitroglycerin. It’s important to inform your doctor if you are taking any form of high blood pressure medication, alpha-blocker medication, prescription antifungals (like fluconazole), or other medications for erectile dysfunction. You should include information about herbal products, especially St. John’s wort.
Do not drink grapefruit juice while taking Levitra.
Talk to your health care provider about safe drinking practices during treatment with Levitra. Levitra can interact with alcohol and cause potentially serious adverse reactions like those above.

Stendra and Cialis are both PDE5 inhibitors used for erectile dysfunction. They work by increasing blood flow to the penis, which helps achieve and maintain an erection. Stendra and Cialis are also effective in treating other sexual health conditions, such as erectile dysfunction, benign prostatic hyperplasia, and pulmonary arterial hypertension.
These medications are available over-the-counter and can be purchased in various forms, including oral tablets, capsules, and injections.
However, it’s important to note that Stendra and Cialis are not FDA-approved for the treatment of erectile dysfunction. This means that their approved uses, such as erectile dysfunction treatments, are not always covered by FDA regulations. Additionally, Stendra and Cialis are not FDA-approved for the treatment of pulmonary arterial hypertension. This means that they are not always available over-the-counter.
Stendra and Cialis contain the same active ingredient and work similarly, with the only difference being that Stendra and Cialis are both prescription drugs and should only be taken by healthcare professionals.
Stendra and Cialis are both PDE5 inhibitors used to treat erectile dysfunction, but they belong to different categories, such as those containing Stendra or Cialis. Stendra and Cialis can be prescribed for both erectile dysfunction and benign prostatic hyperplasia.
However, Stendra and Cialis are not FDA-approved for the treatment of pulmonary arterial hypertension. This means that their approved uses, such as treatment for pulmonary hypertension, are not always covered by FDA regulations. Additionally, Stendra and Cialis are not FDA-approved for the treatment of benign prostatic hyperplasia.

1.Nitrates (e.g., nitroglycerin, isosorbide dinitrate): Cialis and nitrates both lower blood pressure. Taking them together can cause a significant and potentially life-threatening drop in blood pressure (hypotension), leading to dizziness, fainting, or even heart attack or stroke. It is contraindicated to use Cialis with nitrates or recreational "poppers" (amyl nitrites).
2.Alpha-blockers (e.g., prazosin, terazosin, tamsulosin): Both Cialis and alpha-blockers relax blood vessels, which can lead to excessive blood pressure reduction when used together. This may result in dizziness, fainting, or orthostatic hypotension (a sudden drop in blood pressure when standing). If needed, your doctor may adjust the dosage or recommend spacing the medications.
3.Other antihypertensive drugs (e.g., atenolol, propranolol, enalapril, lisinopril): Cialis can enhance the blood-pressure-lowering effects of these medications. While this interaction is usually less severe than with nitrates or alpha-blockers, it can still cause dizziness or fainting in sensitive individuals. Close monitoring of blood pressure is recommended.
Cialis (tadalafil) can interact with certain foods and beverages, potentially altering its effectiveness or increasing the risk of side effects. Here are the key drug-food interactions to be aware of:
