Comparing Tadalafil (Generic Cialis) and Sildenafil (Generic Viagra)

Tadalafil was approved for medical use in the United States in 2003. [7] It is available as a generic medication.

Why is this medication prescribed?

If the side effects are severe or long-lasting, seek prompt medical attention. Comparison of clinical trials with sildenafil, vardenafil, and tadalafil in erectile dysfunction. Tadalafil, sold under the brand name Cialis among others, is a medication used to treat erectile dysfunction, benign prostatic hyperplasia, and pulmonary arterial hypertension. [7] Onset is typically within half an hour and tadalafil pills the duration is up to 36 hours. Common side effects include headache, muscle pain, flushing, and nausea.

Are there any potential serious side effects for Tadalafil?

[7] Caution is advised in those with cardiovascular disease. [7] Rare but serious side effects include a prolonged erection that can lead to damage to the penis, vision problems, and hearing loss. [7] Tadalafil is not recommended in people taking nitrovasodilators such as nitroglycerin, as this may result in a serious drop in blood pressure. [7] Tadalafil is a PDE5 inhibitor which increases blood flow to the penis. [7] It also dilates blood vessels in the lungs, which lowers the pulmonary artery pressure. [8] In 2022, it was the 172nd most commonly prescribed medication in the United States, with more than 3 million prescriptions.

Tadalafil is used to treat erectile dysfunction, benign prostatic hyperplasia, and pulmonary arterial hypertension.

[7] In the United States, tadalafil (as Cialis) is indicated for the treatment of erectile dysfunction and the signs and symptoms of benign prostatic hyperplasia;[4] and (as Adcirca) for the treatment of pulmonary arterial hypertension to improve exercise ability.

• Tadalafil is contraindicated in men taking certain blood pressure medications.
• Women typically should not use tadalafil, and its safety in pregnancy isn't established.
• The medication's duration makes it suitable for flexible planning.
• Some men experience muscle aches or back pain as side effects.
• Tadalafil should not be used in combination with other ED medications.

A meta‐analysis found that tadalafil is an effective treatment for lower urinary tract symptoms due to benign prostatic hyperplasia and that such treatment had a low rate of adverse effects. [11] Tadalafil is FDA-approved for males as a therapy to treat and prevent symptoms of benign prostatic hyperplasia, such as urinary urgency, hesitancy, weak stream, dribbling, and incontinence. Tadalafil was found to have similar benefits for lower urinary tract symptoms as the usually prescribed tamsulosin. Tadalafil is approved in the United States, Canada, and Japan to improve exercise ability in people with pulmonary arterial hypertension. The most common potential side effects when using tadalafil are headache, stomach discomfort or pain, indigestion, burping, acid reflux, back pain, myalgia (pain in limbs and extremities), flushing, hypertension (or uncommonly hypotension), and stuffy/runny nose.

• Before taking tadalafil, discuss your health history with your doctor.
• Men with heart problems should be cautious when using tadalafil.
• Combining tadalafil with certain medications may increase side effects.
• Tadalafil is not suitable for men with severe liver or kidney issues without medical advice.
• Do not double-dose if you miss a pill; consult your doctor for guidance.

[7] Also common are dizziness, peripheral edema, fatigue, and urinary or respiratory tract infection; both diarrhea and constipation have been reported.

Erectile Dysfunction: Oral Therapy Treatment Options

Ultimately, with prices as low as they are, there’s little financial risk in seeing which is best for our patient’s unique circumstances. Regarding how sildenafil and tadalafil work, they are very similar in that they are both PDE-5 inhibitors. This means they slow or stop the action of the phosphodiesterase type five enzyme in the body. This mechanism increases blood flow to the penis when a man is aroused. It’s worth noting, however, that these medications do not increase sexual desire.

Pulmonary arterial hypertension

Instead, they allow the penis to better fill with blood and achieve a satisfactory erection. With both of these drugs, however, patients must realize that they do not have 100% success and that the success rate has a lot to do with the severity of ed. Also, patients must understand that it is normal to have to increase one’s dose as the problem of ED progresses and that nearly all patients who had initial success with ED pills will eventually lose that degree of success and may need other help. Both drugs take approximately 30 to 60 minutes to begin working and allow patients to achieve the erection they expect. Peak concentration in the blood is reached after two hours for tadalafil and about one hour for sildenafil. [7] Diarrhea was reported more frequently in patients 65 or older than in younger subjects.

Both drugs have a relatively mild risk profile. It is worth noting that any side tadalafil sale effects experienced from tadalafil will typically last longer because the drug remains in the bloodstream significantly longer than sildenafil. If you’ve been prescribed ED medication in the past, or if you are looking for a prescription now, you will undoubtedly be asked whether you take nitrates. Nitrates like nitroglycerin can cause a sudden drop in blood pressure and even lead to heart attack or stroke. Patients on nitroglycerin typically have serious cardiovascular issues that make taking ED medication risky in the first place.

What went well

Patients taking recreational “poppers,” including amyl nitrate, amyl nitrite, and butyl nitrate, should not take ED medication. Speak to your doctor or pharmacist about other drug interactions to ensure safety when taking your ED meds. Dr. Engel likes to analogize erectile dysfunction to a roller coaster. Typically, there is a slow movement toward ED. [4] These side effects reflect the ability of PDE5 inhibition to cause vasodilation (causing blood vessels to widen) and usually resolve after a few hours.

• Tadalafil is generally considered effective, with success rates around 70-80%.
• The medication helps improve quality of life for men with ED.
• Some men report quick onset within 30 minutes of taking tadalafil.
• It is important to use tadalafil as part of a healthy lifestyle.
• Regular exercise and proper diet can enhance erectile function.

In May 2005, the US Food and Drug Administration (FDA) found that tadalafil (along with other PDE5 inhibitors) was associated with vision impairment related to NAION (non-arteritic anterior ischemic optic neuropathy).

Online Tadalafil Prescription

Patients taking sildenafil may experience headaches, nausea, flushing, stuffy nose, and on occasion, indigestion, or dizziness. Patients may also develop a blue hue to their vision. Most of these side effects are transient and will disappear after stopping the drug. Loss of vision is a potentially severe side effect of sildenafil in certain very rare clinical situations, and you should stop the drug and get medical help immediately if this occurs, as this can, in very rare cases, lead to permanent blindness. Patients with certain eye problems, cardiovascular and metabolic diseases (high cholesterol, high blood pressure, and type 2 diabetes), and smokers may be at higher risk.

What is Sildenafil?

Patients taking tadalafil have a slightly different side effect profile. Like sildenafil, tadalafil can cause headaches, indigestion, and nasal congestion. However, tadalafil can also cause unique symptoms like back pain, cough, and upper respiratory tract infections. Interestingly, while both drugs have side effects, recent studies have shown that they may reduce the risk of early death from heart disease by up to 25%. This does not make them a treatment for heart disease, nor does it replace any therapies you may currently be taking for cardiovascular issues. [16] Most, but not all, of these patients, had underlying anatomic or vascular risk factors for the development of NAION, unrelated to PDE5 inhibitor use.

• A physical exam and possibly lab tests are often part of the diagnostic process before prescribing tadalafil.
• It can improve confidence and reduce performance anxiety, which are common psychological aspects of ED.
• The peak plasma concentration is reached typically between 2 and 8 hours after ingestion.

[7] The FDA concluded that they were not able to draw a cause and effect relationship, only an association; the label of all three PDE5 inhibitors was changed to alert clinicians to that fact.

Comparing Which Works Faster

However, once erectile dysfunction begins interfering with sexual activity, it is a downward slope that generally cannot be reversed. Erectile dysfunction medications help improve blood flow to the penis at least transiently. However, the underlying vascular issues associated with ED typically worsen with age, and there’s simply nothing we can do about it. As such, eventually, these drugs will no longer offer satisfying erections, at which point we need to consider further treatments, including injections or penile prostheses (implants). While both drugs offer about the same quality of erection, slightly more men achieved a satisfactory erection with sildenafil, according to a study.¹ However, as mentioned above, tadalafil remains in the bloodstream longer and, in the same study, was preferred by more men, probably for that reason.

Benign prostatic hyperplasia explained

With generic prices as low as they are, Dr. Engel believes that there is no single erectile dysfunction drug that should be prescribed to every patient. As mentioned above, each drug has its unique benefit and risk profile, which should be discussed during your consultation. With prices as they are, most patients can safely order both sildenafil and tadalafil to see which works best for them. Of course, if you experience any side effects with either drug, stop and switch to the other medication. A 2019 meta-analysis found that tadalafil exposure was not associated with NAION.

In October 2007, the FDA announced that the labeling for all PDE5 inhibitors, including tadalafil, requires a more prominent warning of the potential risk of sudden hearing loss as the result of post-marketing reports of deafness associated with use of PDE5 inhibitors. Tadalafil is metabolized predominantly[19] by the liver CYP3A4 enzyme system.

How should I take tadalafil?

As such, we always suggest taking medication about an hour or two before sexual activity. The time it takes for the drug to function will vary between patients, so use prior experience as a guide. Of note, sildenafil, a generic Viagra, can be somewhat inhibited after eating a large meal containing fatty foods, and this is not a concern with tadalafil (generic Cialis). We often suggest sildenafil for married couples or long-term partners with a more predictable sex life. Cialis may be more appropriate for patients who are dating, as the big meals often associated with early dating can cause sildenafil to be less effective.

What can I take to enhance Cialis?

Regarding which medication allows an erection to last longer, the clear winner is tadalafil. Sildenafil remains effective for four to six hours, while tadalafil will enable patients to achieve erections up to 36 hours after ingestion, an effect usually seen in younger patients or lesser degrees of ED. In both cases, the drug does not increase desire, instead allowing for a better erection when the desire is present. As with any medication, side effects are associated with both sildenafil and tadalafil. Generally, however, both drugs are well tolerated and have few severe side effects. Penile erection during sexual stimulation is caused by increased penile blood flow resulting from the relaxation of penile arteries and the smooth muscle of the corpus cavernosum.
