It&#8217;s FDA-approved under the brand name Cialis for erectile dysfunction (ED) and benign prostatic hyperplasia (BPH), and under the brand name Adcirca for pulmonary arterial hypertension (PAH). It works by relaxing blood vessels, which increases blood flow to specific tissues. Any use outside these approved indications, including use without a prescription or diagnosis, falls outside the safety data described here.<\/p>\n<h2 id=\"wpb-common\" style=\"font-size: 22px; color: #0f5f2b; margin: 36px 0 12px; padding-top: 8px; border-top: 1px solid #e5e7eb;\">Common Side Effects of Tadalafil<\/h2>\n<p style=\"margin: 0 0 16px;\">The most frequently reported side effects across clinical trials are headache, indigestion (dyspepsia), back pain, muscle aches (myalgia), flushing, and stuffy or runny nose. Other commonly reported effects include nasal\/throat irritation and pain in the extremities.<\/p>\n<ul style=\"margin: 0 0 16px; padding-left: 20px;\">\n<li style=\"margin-bottom: 6px;\"><strong>Headache:<\/strong> the single most commonly reported adverse reaction<\/li>\n<li style=\"margin-bottom: 6px;\"><strong>Indigestion \/ upset stomach<\/strong><\/li>\n<li style=\"margin-bottom: 6px;\"><strong>Flushing<\/strong><\/li>\n<li style=\"margin-bottom: 6px;\"><strong>Stuffy or runny nose<\/strong><\/li>\n<li style=\"margin-bottom: 0;\"><strong>Back pain and muscle aches:<\/strong> these can appear 12 to 24 hours after taking tadalafil and typically resolve within about two days. Over-the-counter pain relievers are generally effective, though a small percentage of patients in trials needed further care.<\/li>\n<\/ul>\n<p style=\"margin: 0 0 16px;\">These effects are consistent with tadalafil&#8217;s mechanism as a mild vasodilator.<\/p>\n<h3 style=\"font-size: 17px; color: #188a3d; margin: 20px 0 8px;\">Tadalafil 20 mg Side Effects: Does a Higher Dose Mean More Risk?<\/h3>\n<p style=\"margin: 0 0 16px;\">Side effect frequency with tadalafil tends to increase somewhat with dose. Headache and upset stomach, for example, are reported more often at 20 mg than at 5 mg. This is why prescribers typically start at a lower dose and adjust based on response and tolerability, and why the as-needed 20 mg dose and the lower-dose daily formulation are prescribed differently. Any change in dose should be made with a prescriber, not independently.<\/p>\n<h2 id=\"wpb-serious\" style=\"font-size: 22px; color: #0f5f2b; margin: 36px 0 12px; padding-top: 8px; border-top: 1px solid #e5e7eb;\">Serious (Rare) Side Effects: When to Seek Emergency Care<\/h2>\n<p style=\"margin: 0 0 16px;\">Most tadalafil side effects are mild and temporary, but a small number of reactions require immediate medical attention.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-108 size-full\" src=\"https:\/\/tadalafil-seller.com\/blog\/wp-content\/uploads\/2026\/07\/2-1.png\" alt=\"Tadalafil Side Effects: Common, Rare &amp; Heart Risks\" width=\"1200\" height=\"650\" srcset=\"https:\/\/tadalafil-seller.com\/blog\/wp-content\/uploads\/2026\/07\/2-1.png 1200w, https:\/\/tadalafil-seller.com\/blog\/wp-content\/uploads\/2026\/07\/2-1-300x163.png 300w, https:\/\/tadalafil-seller.com\/blog\/wp-content\/uploads\/2026\/07\/2-1-1024x555.png 1024w, https:\/\/tadalafil-seller.com\/blog\/wp-content\/uploads\/2026\/07\/2-1-768x416.png 768w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><\/p>\n<div style=\"background: #fef2f2; color: #991b1b; border: 1px solid #fecaca; border-radius: 8px; padding: 16px 20px; margin: 16px 0; font-size: 15px;\">\n<ul style=\"margin: 0; padding-left: 20px;\">\n<li style=\"margin-bottom: 8px;\"><strong>Priapism (a prolonged erection).<\/strong> An erection lasting longer than four hours is a medical emergency; seeking prompt care helps avoid lasting damage to erectile tissue.<\/li>\n<li style=\"margin-bottom: 8px;\"><strong>Sudden vision loss.<\/strong> Rare reports describe sudden decreased or lost vision in one or both eyes among men taking PDE5 inhibitors including tadalafil, sometimes associated with a condition called non-arteritic ischemic optic neuropathy (NAION).

A 2024 systematic review and meta-analysis pooling over 1.2 million subjects across 16 cohort studies found that PDE5 inhibitor use, including tadalafil, was associated with a lower rate of major adverse cardiovascular events (MACE) and all-cause mortality compared with non-use.<\/p>\n<div style=\"background: #fff7ed; color: #9a3412; border: 1px solid #fed7aa; border-radius: 8px; padding: 16px 20px; margin: 16px 0; font-size: 15px;\"><strong style=\"display: block; margin-bottom: 6px;\">Important:<\/strong><br \/>\nThese are observational, association-based findings, not evidence that tadalafil actively protects the heart or reduces cardiovascular risk for any individual. They should not be read as a treatment benefit. Men with cardiovascular disease, a recent heart attack or stroke, or unstable angina should be evaluated by a physician before using tadalafil.<\/div>\n<p style=\"margin: 16px 0 8px;\"><strong>Who needs extra caution:<\/strong><\/p>\n<ul style=\"margin: 0 0 16px; padding-left: 20px;\">\n<li style=\"margin-bottom: 6px;\">Men taking alpha-blockers for blood pressure or an enlarged prostate (risk of additive blood-pressure-lowering effects)<\/li>\n<li style=\"margin-bottom: 6px;\">Men with a history of heart disease, low or uncontrolled blood pressure, or a recent cardiac event<\/li>\n<li style=\"margin-bottom: 0;\">Men who drink alcohol heavily while taking tadalafil, which can compound blood-pressure and heart-rate effects<\/li>\n<\/ul>\n<h3 style=\"font-size: 17px; color: #188a3d; margin: 20px 0 8px;\">Long-Term Side Effects of Tadalafil (Daily-Use Data)<\/h3>\n<p style=\"margin: 0 0 16px;\">For men prescribed a lower-dose, once-daily tadalafil (rather than the as-needed 20 mg dose), longer clinical trials have tracked side effects over time. In studies of daily dosing, discontinuation due to adverse events occurred in roughly 3.6% to 4.1% of tadalafil-treated patients compared with about 1.6% to 2.8% of those on placebo. In a one-year open-label extension study, back pain and muscle aches were reported in 5.5% and 1.3% of patients, respectively. Most patients who experienced back pain or myalgia on tadalafil did not need to stop treatment because of it: about 0.5% discontinued for that specific reason.<\/p>\n<h2 style=\"font-size: 22px; color: #0f5f2b; margin: 36px 0 12px; padding-top: 8px; border-top: 1px solid #e5e7eb;\">Who Should NOT Take Tadalafil<\/h2>\n<div style=\"background: #fef2f2; color: #991b1b; border: 1px solid #fecaca; border-radius: 8px; padding: 16px 20px; margin: 16px 0; font-size: 15px;\">\n<ul style=\"margin: 0; padding-left: 20px;\">\n<li style=\"margin-bottom: 6px;\">Anyone currently taking any form of organic nitrate medication<\/li>\n<li style=\"margin-bottom: 6px;\">Anyone with a known serious allergy to tadalafil or Cialis<\/li>\n<li style=\"margin-bottom: 6px;\">Men with severe hepatic (liver) impairment<\/li>\n<li style=\"margin-bottom: 6px;\">Men advised against sexual activity due to underlying heart conditions<\/li>\n<li style=\"margin-bottom: 0;\">Anyone with a prior episode of NAION (a specific type of vision loss), per prescriber judgment<\/li>\n<\/ul>\n<\/div>\n<p style=\"margin: 0 0 16px;\">This list is not exhaustive.
