Is Low-Dose Daily Cialis/Tadalafil Effective in Treating Erectile Dysfunction/ED

Cialis (Tadalafil) is best known as a treatment for erectile dysfunction, but it is also approved for benign prostatic hyperplasia (BPH), or an enlarged prostate. The dosage differs depending on the condition - higher doses of up to 20mg as-needed are typically used for ED, while lower daily doses around 5mg are prescribed for BPH.

With the arrival of affordable generics, many men have begun using the lower BPH daily dose as a baseline therapy for tackling ED. The idea is that a steady, low level of the drug in the system might improve the odds of achieving an erection when you want it. But does this daily low-dose strategy actually do the trick, or is it just money down the drain?

What Does 'Low-Dose' Mean?

5 mg is the trending low-dose "sweet spot" of Tadalafil for managing ED. For mild ED, that amount can be enough to improve blood flow and sexual function, making an erection more reliable and intercourse more pleasurable.

But for men with moderate erectile dysfunction, 5 mg daily may not provide enough support on its own. In those cases, doctors often recommend a higher dose taken on demand - usually upwards of 20mg about an hour before sexual activity - to achieve and maintain a firm erection.
This daily low-dose trend can be effective, but it works best when matched to the severity of ED and guided by a doctor's recommendation.

Are There Any Other Benefits?

As mentioned above, low-dose daily Tadalafil is approved for treating BPH, where it helps relax the muscles of the prostate and bladder. Evidence suggests that this relaxation can improve urinary flow and ease some of the mild symptoms of an enlarged prostate. But there is also evidence of health improvements in other parts of the body.

Cialis/Tadalafil is called a PDE5 inhibitor, and because the drug is taken orally, its effects are systemic - meaning patients may notice some, albeit modest, benefits beyond the primary indication. That said, it also relaxes the smooth muscles in blood vessels, allowing them to expand and improving blood flow throughout the body, not just to the reproductive organs.

Overall, cardiovascular function benefits from improved circulation. While PDE5 inhibitors are not a treatment for heart disease and should not be relied upon to manage complex cardiovascular conditions, they may provide a small, supportive effect. Patients taking Cialis for BPH or ED might find that enhanced blood flow contributes to general wellness, energy, and even subtle improvements in vascular health.

There is also very preliminary evidence showing that PDE-5 inhibitors may also have an advantageous effect on cognition, with the potential for improving age-related cognitive decline, including dementia and Alzheimer's. Once again, there is no solid evidence that these pills should be used as a therapeutic option, and they are not approved for this indication, but the possible blood flow increase to the brain makes sense.

PDE-5 Inhibitors Come With Drawbacks

All prescription drugs come with potential downsides, and PDE5 inhibitors like Cialis and Viagra are no exception. Fortunately, their overall side effect profile is relatively low.

Certain patients, however, should avoid these medications - for example, anyone taking certain ED medications along with nitrates for heart disease could experience a potentially fatal drop in heart rate. Drinking large quantities of alcohol while on medications like Cialis may also cause a drop in blood pressure. Patients with retinal issues should consult their doctor, urologist, and ophthalmologist to ensure it is safe. While there seems to be some evidence linking some ED medications with serious ocular adverse events, the absolute risk remains low, and the benefits for erectile dysfunction often outweigh the risks for most patients.

Usually, the side effects are mild. Common complaints include flushing, headaches, and nasal congestion. Some Cialis users may also notice an unusual sensation in the back, which can range from mild discomfort to more noticeable pain.

Another drawback is that pharmaceutical therapy can lose effectiveness over time. Some patients will experience progressively worsening symptoms, eventually considering a BPH procedure or surgical intervention to reduce prostate size.

The Bottom Line

For ED, the favorable safety profile of PDE5 inhibitors makes low-dose Cialis a straightforward option to discuss for men with erectile dysfunction and/or BPH. Consulting a men's health urologist is the best way to determine whether it offers meaningful benefits.

For patients with erectile dysfunction, the first and most crucial step is to identify the underlying problem. Many patients hope that their ED is only temporary, but this is rarely the case. Erectile dysfunction often progresses over time, and most patients will require medication to achieve and maintain an erection.

When going the medication route for ED, we typically start with a slightly higher dose (10 mg of Cialis/Tadalafil or 50 mg of Viagra/Sildenafil) taken as needed to see if patients can achieve the on-demand erection that they want. From there, the dosage can be adjusted, and fortunately, the drugs are typically interchangeable. (We have a comparison of Cialis/Tadalafil vs Viagra/Sildenafil here.)

For patients dealing with an enlarged prostate, it's important to understand that any erectile benefits from a low-dose daily Tadalafil pill will be modest. While it may help manage symptoms of BPH and mild ED, most patients will benefit from exploring the full range of treatment options so that expectations remain realistic and long-term outcomes are optimized.

At Georgia Urology, your options run the gamut - from pharmaceutical therapies and minimally invasive procedures that take just a few minutes to more extensive surgical interventions when appropriate. We've also recently opened a state-of-the-art IR center specializing in Prostatic Artery Embolization (PAE), one of the most promising non-surgical treatments for an enlarged prostate.
