Cialis AdWatch—deconstructing the ED drug ad

The United States Coast Guard is rightly proud of its longstanding motto, Semper Paratus (Latin for Always Ready). But the term took on a new meaning in January, when the Food and Drug Administration (FDA) approved the new once daily 2.5 mg and 5mg doses of tadalafil (Cialis), one of three oral drugs available for the treatment of erectile dysfunction. The drug, manufactured by pharmaceutical giant Eli Lilly and the third in a new class of drugs known as phosphodiesterase (PDE) inhibitors, was originally approved in 2003 for use on an "as you need it" basis.

In this, our third video in the Consumer Reports AdWatch series, we dissect a recent Cialis ad and tell you some information that the ad doesn't. Our accompanying Web piece also outlines some preventive measures you should consider before asking your doctor for a drug treatment.

Affectionately known as "The Weekender," Cialis differs from its two predecessors, sildenafil (Viagra) and vardenafil (Levitra) by having a chemical structure that prolongs its effect for up to 36 hours. That's more than seven times longer than its brother drugs. The advertising moguls (Eli Lilly spent close to $152 million promoting Cialis to the public in 2007) explain the drug's longer half-life by touting the advantages of sexual spontaneity and avoiding having to plan sexual relations in advance. And now, with the approval of the daily dose, the impotent male can be semper paratus for any opportunity.

Such convenience and ease of use has the potential to overlook several warnings about side effects and precautions. Side effects common to Cialis (and the other two PDE inhibitors) include headache, heartburn, muscular aches and pains, runny nose, and flushing. Much less common are potential adverse reactions, such as visual and hearing problems. Priapism (prolonged erection) can be a medical emergency.

The use of certain drugs absolutely precludes the use of Cialis (and the other two PDE inhibitors). Those drugs include nitrates (Imdur, Ismo, Isordil, and Nitro-dur), often used for heart pain. Caution is also advised if a class of medications known as alpha blockers are being taken because of the risk of blood pressure dropping too much. These are used by some not only to treat high blood pressure but also for treating symptoms associated with having an enlarged prostate. They include doxazosin (Cardura), tamsulosin (Flomax), and terazosin (Hytrin). Other drugs, such as the antibiotic erythromycin and certain anti-fungal drugs may increase blood levels of Cialis and add to the possibility of side effects. The same may well apply to grapefruit juice.

The cost—though less than the other doses—is not inconsequential when taken every day and insurance coverage can be limited. At about $5 per dose, a daily 2.5 mg Cialis may not prove to be as popular as the original 20 mg weekender version.

This article and video is VERY informative and should have a mass viewing. That ED meds can cause long term harm is frightening and frankly, it should be illegal to solicit meds directly to consumers.

Marvin,
Bravo for your blog piece and survey. It highlights several problematic issues: (1) Physician prescribing is subject to market forces, pharmaceutical sales representative visits and ad campaigns, (2) direct to consumer advertising is a highly effective marketing strategy to physicians because we are not using evidence-based information for prescribing. Shame on us.

Thanks for taking on this important topic and sharing essential health information with the public. I have met so many college aged men who take Cialis and related meds recreationally, often without carefully working with a physician. The one sided, faulty information they have received does not give them an appropriate framework for such decisions but their money remains green.

I could not understand the CU spokeswoman, because she spoke too fast. I did understand the Ciallis actors. I am 84, and moderately hard of hearing. I understood more when I listened with headphones.
It was startling to read that Ciallis should not be taken with Terazosin, which I take. I would never have realized that from the TV ad.
Thank you, CU!

Your AdWatch series is very informative. With Jamie Hirsch, the same ad I see on TV is dissected and becomes something else: the drug company's attempt to persuade me that their medicine can help everyone, every time. The presentation is very eye-opening, and, unfortunately, necessary.
