• Sublingual tadalafil dissolves quickly under the tongue for faster absorption.
• Typically used to treat erectile dysfunction (ED) and sometimes benign prostatic hyperplasia.
• Onset of action is usually faster than oral tablets, often within 15-30 minutes.
• Effects can last up to 36 hours, allowing for greater spontaneity.
• Avoid eating or drinking immediately after placing the tablet under the tongue.
• Dosage should be prescribed by a healthcare professional based on individual needs.
• Common side effects include headache, flushing, and nasal congestion.
• Not recommended for use with nitrates or certain blood pressure medications.

Tadalafil was approved for medical use in the United States in 2003.

[7] It is available as a generic medication.

[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.

FOR ERECTILE DYSFUNCTION?

Tadalafil can be a sensitive conversation, but providers can normalize the dialogue with the right framing. Set Expectations – Sexual stimulation is required; tadalafil does not create arousal on its own. Reinforce Suitability – Remind patients of nitrate contraindication, caution with alcohol, and warning signs of priapism. Individualize Care – Use flex-dosing to find the lowest beneficial dose. Normalize Sexual Wellness – Position ED and urinary symptoms as part of whole-patient health, not isolated or shameful issues.

Some side effects can be serious. If you experience any of these symptoms, call your doctor immediately or get emergency medical treatment:

This combination of clinical precision and empathetic counseling helps patients feel both supported and empowered. Many patients ask about the difference between tadalafil and sildenafil. Duration: Tadalafil lasts up to 36 hours vs. sildenafil’s 4–6 hours.6 Onset: Sildenafil often works slightly faster; sublingual tadalafil narrows this gap.11 Daily Use: Tadalafil is well-suited for once-daily dosing, especially when managing both ED and BPH.10 Tolerance: Potential side effect profiles overlap, but individual patient experience often determines preference. Providers may find value in framing tadalafil as the “longer, steadier option” and sildenafil as the “shorter, quicker boost.” Both have their place; patient goals and lifestyle guide the choice. [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. 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.

Preclinical studies suggest PDE5 inhibitors like tadalafil are being studied for broader health outcomes. Cardioprotective effects – Evidence suggests possible improvements in endothelial function and reduced risk of certain cardiovascular events.7 Neuroprotective effects –Early preclinical studies in mice suggest potential benefits in reducing inflammation and supporting cognitive function.8 Exercise and muscle recovery – PDE5 inhibitors may decrease muscle fatigue and stimulate protein synthesis, augmenting resistance training outcomes.9 While not yet a clinical standard of care, these findings are worth watching—and may shape the future conversation around tadalafil as more than a sexual health medication. For providers new to compounding tadalafil—or expanding patient access to daily formulations—the following steps help ensure appropriate prescribing: Start Low, Adjust Thoughtfully – Begin with the lowest beneficial dose, titrate with flex-splitting as needed. Screen Thoroughly – Always confirm no nitrate use, assess CV status, and evaluate hepatic/renal function.5 Educate Patients Clearly – Sexual stimulation is required for tadalafil to work, possible side effects, and when to seek help. Consider Lifestyle Fit – Daily vs.

on-demand is less about efficacy and more about patient preference. Leverage Compounded Advantages – Sublingual, flavored formulations improve adherence and patient experience. For many patients, it represents freedom from rigid scheduling, relief from urinary symptoms, and improved confidence in daily life.5 For providers, it’s an opportunity to normalize sexual wellness, integrate urinary and pulmonary health into the conversation, and explore emerging cardiometabolic frontiers. When prescribed thoughtfully—with clear guardrails and patient-centered counseling—tadalafil becomes a flexible, powerful ally in whole-patient care. At Strive, we believe compounding isn’t about covering up symptoms; it’s about building something customized for patients who deserve more than short-term fixes and “one-size-fits-all” solutions. [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.

Adverse effects

Nitrates (e.g., nitroglycerin, isosorbide) → dangerous, potentially fatal hypotension.4 Excessive alcohol → increases dizziness, blood pressure swings. Hepatic or renal impairment → dose adjustment often required. Retinal disorders → risk of sudden vision changes. Sudden vision loss in one or both eyes may be a sign of nonarteritic anterior ischemic optic neuropathy (NAION). While a direct relationship has not been established, NAION has been reported in rare cases and may result in permanent vision loss.

Patients should report any sudden loss of vision immediately. Pulmonary veno-occlusive disease (PVOD) → avoid use. Priapism – Requires emergency intervention if erection lasts >4 hours. Sudden hearing or vision loss – Counsel patients to discontinue immediately and seek evaluation. When patients understand possible side effects, they are more likely to report concerns early and use medications appropriately . 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.

• Sublingual tadalafil offers a non-invasive option for ED management.
• Absorption under the tongue bypasses first-pass metabolism in the liver.
• May interact with certain medications like alpha-blockers and antifungals.
• Onset variability can depend on individual metabolic rates and health status.
• Discuss any existing medical conditions or medication history with your doctor.
• Treatment effectiveness may improve psychological confidence in ED patients.
• Storage in original packaging protects from moisture and degradation.
• Regular follow-up is advised to reassess dosage and efficacy.

Before taking tadalafil,

Neuroprotective effect of tadalafil, a PDE-5 inhibitor, and its modulation by L-NAME in a mouse model of ischemia-reperfusion injury. Tadalafil is categorized as a Selective Phosphodiesterase type 5 (PDE5) inhibitor, which is similar to Sildenafil and Vardenafil. This is prescribed for the treatment of male erectile dysfunction (ED), pulmonary arterial hypertension (PAH), benign prostatic hypertrophy (BPH), or the concurrent treatment of erectile dysfunction and BPH. The duration of action of tadalafil for the treatment of ED can last up to 36 hours, which appears to be longer than that of Sildenafil and Vardenafil. 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] Diarrhea was reported more frequently in patients 65 or older than in younger subjects.

Medical uses

[7] Onset is typically within half an hour and the duration is up to 36 hours. Common side effects include headache, muscle pain, flushing, and nausea. [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. [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. 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).
