Benign prostatic hyperplasia is a condition in which the prostate gland becomes enlarged, obstructing the free flow of urine. Symptoms may include sudden urges to urinate (urgency), difficulty in starting urination (hesitancy), a weak urine stream, and more frequent urination—especially at night. The FDA has also approved tadalafil for the treatment of both benign prostatic hyperplasia and erectile dysfunction where the two conditions co-exist. In the United States, the FDA relaxed rules on prescription drug marketing in 1997, allowing advertisements targeted directly to consumers. [34] Lilly-ICOS hired the Grey Worldwide Agency in New York, part of the Grey Global Group, to run the Cialis advertising campaign.
[35] Marketing for Cialis has taken advantage of its greater duration compared to its competitors in advertisements for the drug; Stuart Elliot of The New York Times opined: "The continuous presence of females in Cialis ads is a subtle signal that the drug makes it easier for them to set the pace with males, in contrast to the primarily male-driven imagery for Levitra and Viagra. "[35] Iconic themes in Cialis ads include couples side by side in matching bathtubs and the slogan "When the moment is right, will you be ready? "[35] Cialis ads were unique among the ED drugs in mentioning specifics of the drug. [36] As a result, Cialis ads were also the first to describe the side effects in an advertisement, as the FDA requires advertisements with specifics to mention side effects. One of the first Cialis ads aired at the 2004 Super Bowl. Archived from the original on 10 September 2015. Archived from the original (PDF) on 29 August 2021.

Both Cialis and Viagra are proven options for men with diabetes; Cialis lasts up to 36 hours with a daily option, while Viagra works for about 4 to 6 hours and often performs best on an empty stomach.
[36] Just weeks before the Super Bowl, the FDA required more possible side effects to be listed in the advertisement, including priapism. [36] Although many parents objected to the Cialis ad being aired during the Super Bowl, Janet Jackson's halftime "wardrobe malfunction" overshadowed Cialis. [36] In January 2006, the Cialis ads were tweaked, adding a doctor on screen to describe side effects and only running ads where more than 90 percent of the audience are adults, effectively ending Super Bowl ads. [34] In 2004, Lilly-ICOS, Pfizer, and GlaxoSmithKline spent a combined $373.1 million to advertise Cialis, Viagra, and Levitra respectively. [36] Cialis has sponsored many sporting events, including the America's Cup and the PGA Tour, once being title sponsor of the PGA Tour Western Open tournament.
In Australia, tadalafil is subsidized through the Repatriation Pharmaceutical Benefits Scheme (RPBS) for patients with a specific accepted war- or service-related disability. In the US, a generic version of tadalafil is available. [39] While some health insurance providers cover at least part of the cost (typically limiting the number of doses covered per month), many providers, including those operating under Medicare Part D, do not cover the cost of medications prescribed for erectile dysfunction. In the UK, a generic version of tadalafil became available in November 2017, reducing its price per pill, and is available through the NHS. [citation needed] In China, CMOAPI is the largest manufacturer of Tadalafil powder. The best choice depends on your goals, side effects, other medications, heart safety, and blood sugar control, and alternatives exist if pills do not work, so discuss a trial and follow up with your clinician. There are several factors to consider, see complete details below to guide your next steps. Discover which ED pill may suit youLearn if erectile issues need care todaySee if symptoms suggest diabetes-related EDFind OTC options for sexual side effectsFind a doctor for erectile dysfunctionUnderstand medically valid ED home remediesFind out if treatment matches your symptoms Erectile dysfunction (ED) is very common in men with diabetes. In fact, men with diabetes are two to three times more likely to develop ED than men without it. High blood sugar over time can damage blood vessels and nerves — both of which are essential for getting and maintaining an erection. If you're managing diabetes and ED, you may be wondering: Which ED pill is best? Both belong to a class of medications called PDE5 inhibitors, and both are proven to help many men with diabetes. Let's break down the differences, what research shows, and how to decide what's right for you. Damage blood vessels (reducing blood flow to the penis) Because ED in diabetes often has both physical and psychological causes, treatment needs to address the whole picture. Help you achieve and maintain an erection They work by relaxing blood vessels and allowing more blood to enter the penis during arousal. However, they differ in timing, duration, and dosing flexibility — which can matter a lot for men with diabetes. Can be taken with or without food Some men with diabetes prefer Cialis because: It offers a longer window of opportunity Viagra works well, but the shorter window may feel more "scheduled." It can be taken daily at a low dose Or used as needed at a higher dose Help men who have frequent sexual activity For some men with diabetes — especially those with more consistent ED — daily Cialis may provide steadier results. Both medications are effective in diabetic men, but response rates are slightly lower compared to men without diabetes.
That's because diabetic ED often involves more severe blood vessel damage.

Viagra improves erections in about 50–60% of men with diabetes Cialis shows similar effectiveness, sometimes slightly higher in certain studies Some men respond better to one than the other.
| Medication | Active Substance | Onset of Action | Duration of Effect | Common Side Effects | Special Notes |
|---|---|---|---|---|---|
| Cialis (Tadalafil) | Tadalafil | 30–60 min | Up to 36 hours | Headache, flushing, back pain | Food does not affect absorption |
| Viagra (Sildenafil) | Sildenafil | 30–60 min | 4–6 hours | Visual disturbances, headache | Taken on an empty stomach |
| Levitra (Vardenafil) | Vardenafil | 30–60 min | 4–5 hours | Dizziness, flushing | More effective with high-fat meals |
If one doesn't work, it does not mean ED treatment won't work for you. Most side effects are mild and temporary.
However, you should not take either medication if you: Have been advised to avoid sexual activity If you experience chest pain, severe dizziness, or an erection lasting longer than four hours, seek immediate medical care. ED pills work best when diabetes is well-managed. If your ED medication isn't working as expected, your doctor may check: There is no single "best" pill for every man.
