Rapaflo vs Uroxatral
Introduction
For patients with Benign Prostatic Hyperplasia (BPH) or other types of urination problems, certain drugs that relax the muscles in the prostate and bladder can help improve symptoms. Rapaflo and Uroxatral are two such drugs prescribed for these conditions. They each function by obstructing alpha-adrenergic receptors in the lower urinary tract, thereby reducing smooth muscle tone in the prostate and bladder neck to ease urine flow and decrease symptoms of BPH. Rapaflo is classified as a selective antagonist at alpha-1a adrenoceptors, which are found predominantly in the prostate tissue. Uroxatral, on the other hand, also targets similar receptors but has been shown to have less impact on blood pressure compared to other drugs in its class.

What is Rapaflo?
Silodosin (the generic name for Rapaflo) was a significant advancement in the class of drugs known as alpha blockers, which were designed to treat symptoms of an enlarged prostate. Silodosin was first approved by the FDA in 2008. Rapaflo works by relaxing muscles in the prostate and bladder neck, making it easier to urinate. It is prescribed for men who have been diagnosed with benign prostatic hyperplasia (BPH). Unlike Alfuzosin (Uroxatral), another drug from this category, Silodosin has a selective influence on certain receptors located in the prostate and bladder, minimizing effect on other receptors elsewhere in body. This specificity results in fewer side effects than those experienced with Uroxatral which influences more receptor types.
What conditions is Rapaflo approved to treat?
Rapaflo is approved for the treatment of certain urinary problems:
- Benign Prostatic Hyperplasia (BPH), also known as prostate gland enlargement
Uroxatral, on the other hand, is permitted for use in:
- Treating symptoms of Benign Prostatic Hyperplasia (BPH)
- Improving urination in men with enlarged prostates
How does Rapaflo help with these illnesses?
Rapaflo helps to manage symptoms of benign prostatic hyperplasia (BPH), or an enlarged prostate, by relaxing the muscles in the bladder neck and prostate. It does this by blocking alpha-1 adrenergic receptors, which are involved in muscle contraction. This relaxation allows for easier urination and lessens other related symptoms like frequent need to urinate and weak stream. Alpha-1 adrenergic receptors play a crucial role in regulating smooth muscle tone throughout the body, including that within blood vessels and certain muscular tissues. In BPH patients, these receptors can be overly responsive leading to constricted urinary flow from the bladder through urethra that passes through prostate gland. Therefore, by blocking these receptors with Rapaflo medication it inhibits their action hence alleviating BPH symptoms allowing patients manage their condition easier.
What is Uroxatral?
Uroxatral, also known as alfuzosin, is an alpha-1 blocker used to relieve symptoms of enlarged prostate (benign prostatic hyperplasia or BPH). By relaxing the muscles in and around the prostate and bladder, it can help improve urine flow and decrease your need to urinate frequently. Alfuzosin was first approved by the FDA in 2003. Unlike Rapaflo (silodosin), Uroxatral does not typically cause 'retrograde ejaculation' - a condition where semen enters the bladder instead of emerging through the penis during orgasm. This means that its side-effect profile may be more preferable for some men than that of other medications like Rapaflo. The effects on muscle relaxation can be beneficial for improving urinary symptoms, especially in patients who do not respond well to other treatments for BPH.
What conditions is Uroxatral approved to treat?
Uroxatral, also known as alfuzosin, is a medication approved for treatment of:
- Benign prostatic hyperplasia (BPH), which is essentially an enlarged prostate causing difficulties with urination
- Lower urinary tract symptoms related to BPH such as difficulty in beginning the flow of urine, weak stream and the need to urinate frequently or urgently.
How does Uroxatral help with these illnesses?
Uroxatral, just like Rapaflo, is a type of medication known as an alpha-blocker and plays a crucial role in relaxing the muscles in the bladder neck and prostate. This function makes it easier for men with benign prostatic hyperplasia (BPH) to urinate. Uroxatral works by blocking adrenergic receptors on smooth muscle tissue within the prostate and bladder neck, aiding in urinary flow without affecting serotonin or norepinephrine levels significantly. It can be used when patients do not respond well to other BPH medications or combined with them for more effective results. Its action does differ from Rapaflo slightly; while both help relax muscles to improve urine flow, Uroxatral also slows down the process of hormone stimulation which contributes to prostate growth - an underlying cause of BPH.
How effective are both Rapaflo and Uroxatral?
Both silodosin (Rapaflo) and alfuzosin (Uroxatral) have established histories of success in treating benign prostatic hyperplasia (BPH), a condition that can cause issues with urination due to an enlarged prostate. They were approved by the FDA within 4 years of each other, Rapaflo in 2008 and Uroxatral in 2003. As alpha-1 blockers, they work by relaxing muscles in the bladder neck and prostate which makes it easier to urinate. Both drugs demonstrated effectiveness at relieving symptoms such as frequent or urgent need to urinate, weak urine stream, difficulty starting a urine flow or straining when urinating.
A study conducted in 2010 showed both drugs had similar efficacy at alleviating symptoms related to BPH but noted some differences between them. For instance, patients taking silodosin reported increased instances of abnormal ejaculation compared to those taking alfuzosin.
Silodosin is considered effective from the first few days of treatment according its clinical trials data; it has a favorable side effect profile amongst most users except for retrograde or diminished ejaculation which could be problematic for sexually active men seeking children.
Alfuzosin has been studied extensively since its approval almost two decades ago and has proven effective against BPH-related urinary tract symptoms even among elderly populations without causing drastic changes on sexual function like decreased libido or erectile dysfunction seen commonly with this class of medication.
Given their mechanism action on different subtypes of alpha receptors (silodosin works primarily on Alpha-1a subtype while Alfuzosine works non-selectively), the choice between these two medications often comes down patient’s individual preference based upon tolerability towards side effects and physician's assessment about comorbidity status especially cardiovascular health.

At what dose is Rapaflo typically prescribed?
Oral dosages of Rapaflo are typically 8 mg/day, taken once daily with a meal. This dosage has been shown to be effective in treating signs and symptoms of benign prostatic hyperplasia (BPH) in most men. On the other hand, Uroxatral is usually prescribed at a dose of 10 mg/day, also taken once daily immediately after the same meal each day. In both cases, if there's no improvement observed within a few weeks or if the condition worsens, it would be advisable to consult your healthcare provider. The maximum dosage for either medication should not exceed their respective standard doses per day.
At what dose is Uroxatral typically prescribed?
Uroxatral treatment typically begins with a dosage of 10 mg/day, taken after the same meal each day. The dosing time should be consistent to maintain steady levels of the drug in your system. In some cases, if there's no improvement or response to treatment at 10 mg/day after several weeks, doctors may consider increasing the dose. However, this rarely happens as exceeding a daily dose of 10mg can lead to unwanted side effects and isn't generally recommended without careful medical supervision.
What are the most common side effects for Rapaflo?
When comparing Rapaflo to Uroxatral, common side effects may include:
- Dizziness, particularly when standing up from a sitting or lying position
- Headache
- Fatigue (general weakness and tiredness)
- Nasal congestion
- Sinusitis (inflammation of the sinus cavities in the head)
- Pharyngitis (inflammation in the back of the throat)
- Diarrhea
- Nausea
- Decreased libido (sex drive)
- Abnormal ejaculation In rare cases, these medications can cause severe skin reactions. If you notice any unusual symptoms while taking either of these drugs, seek medical attention immediately. Always consult with your healthcare provider before making changes to your medication regimen.
Are there any potential serious side effects for Rapaflo?
Rapaflo and Uroxatral are two medications used to treat benign prostatic hyperplasia (BPH). While they're generally well-tolerated, some users may experience adverse reactions which can be serious, including:
- Signs of allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat
- Chest pain or pressure, a fast heartbeat
- A light-headed feeling like you might faint

A few people have experienced more severe side effects like:
- Low blood pressure leading to dizziness upon standing up quickly.
- Priapism (a prolonged erection that lasts for more than 4 hours), which could lead to permanent damage if not treated immediately.
These lists do not cover all possible side effects. If you notice any other changes while taking either medication seek medical attention promptly.
What are the most common side effects for Uroxatral?
Uroxatral, also known as Alfuzosin, can cause several side effects such as:
- Dizziness or lightheadedness
- Headache
- Tiredness
- Upper respiratory tract infection symptoms like stuffy nose and sore throat
- Stomach discomfort or pain that may be accompanied by nausea or vomiting
- Decreased appetite leading to weight loss in some individuals
- A rapid heartbeat which could lead to feelings of anxiety or nervousness
- Sleep disturbances including insomnia
- Increased frequency of urination
However, it's important to note that not everyone experiences these side effects and they're often temporary. If you have any concerns about taking Uroxatral, speak with your healthcare professional for personalized advice.
Are there any potential serious side effects for Uroxatral?
While Uroxatral is generally safe to use, it's important to note that it may cause some serious side effects in rare situations. Signs of a severe allergic reaction include hives, itching, fever, swollen glands or swelling in your face or throat. You may also experience breathing difficulties or severe skin reactions like blistering and peeling rashes. Other possible risks include fainting spells due to low blood pressure and complications with heart rhythm leading to fast or irregular heartbeats. It’s necessary to seek immediate medical attention if you notice blurred vision as this could be an indicator of more serious eye problems associated with the drug usage. Similarly, if you observe any changes in mood behavior such as agitation, restlessness or confusion after taking Uroxatral, consult your healthcare provider immediately.
Contraindications for Rapaflo and Uroxatral?
Both Rapaflo and Uroxatral, like many medications for benign prostatic hyperplasia (BPH), can cause some side effects. If you notice a severe decrease in sexual desire or ability; dizziness, lightheadedness, or fainting especially when standing from a sitting or lying position; unusual tiredness/weakness; chest pain/pressure or other serious side effects, please seek immediate medical attention.
Neither Rapaflo nor Uroxatral should be taken if you are taking certain other medications like strong CYP3A4 inhibitors such as ketoconazole, itraconazole and clarithromycin. Always inform your physician which medications you're using; these potent inhibitors will need an appropriate washout period to prevent dangerous interactions with both Rapaflo and Uroxatral.
How much do Rapaflo and Uroxatral cost?
For the brand name versions of these drugs:
- The price of 30 capsules of Rapaflo (8 mg) averages around $365, which works out to approximately $12/day.
- The price for 30 tablets of Uroxatral (10 mg) is about $170, working out to roughly $5.66/day.
Thus, if you are taking one tablet/capsule per day as recommended by your healthcare provider, then brand-name Uroxatral is less expensive on a per-day treatment basis than Rapaflo. Please note that cost should not be a primary consideration in determining which drug is right for you; effectiveness and side effects are also important factors.
As far as generic versions go:
- Silodosin (generic Rapaflo), with dosages at 8mg, comes in packs from 20 up to 100 capsules and costs can range between $1.50 and $4.00 per day depending on the package size.
- Alfuzosin (generic Uroxatral) comes in packs from 20 up to 90 tablets at a dose of 10mg each with daily costs ranging from about $.80 to just over two dollars ($2).
Again, prices will vary based on pharmacy location and insurance coverage but generally speaking alfuzosin (Uroxatral's generic counterpart) tends to be cheaper than silodosin (Rapaflo's generic version).
Popularity of Rapaflo and Uroxatral
Silodosin, marketed under the brand name Rapaflo, is a medication used to treat symptoms of an enlarged prostate. In 2020 it was estimated that about 1 million people in the US were prescribed Silodosin. Accounting for around 5% of prescriptions for benign prostatic hyperplasia (BPH), Silodosin's use has been generally increasing since its approval by FDA in 2008.
Alfuzosin, on the other hand, known by its brand name Uroxatral among others, was prescribed to approximately 800 thousand people in the USA in 2020. Alfuzosin accounts for just under 4% of BPH prescriptions and has seen a steady usage over the past decade. Both medications are alpha blockers with similar efficacy and side effect profiles but may differ slightly based on individual patient characteristics or potential drug-drug interactions.
Conclusion
Both Rapaflo (silodosin) and Uroxatral (alfuzosin) are used to treat the symptoms of benign prostatic hyperplasia (BPH), a condition that causes an enlarged prostate. Both drugs work by relaxing the muscles in the prostate and bladder neck, which can help improve urine flow and decrease BPH symptoms. They have been proven effective through numerous clinical trials.
Rapaflo tends to be prescribed for men who need immediate relief of their urinary symptoms as it works quickly, often within three days. Uroxatral, on the other hand, is considered a first-line treatment option for long-term management of BPH due to its once-daily dosing regimen.
Both drugs are available in generic form, providing cost savings especially for patients paying out-of-pocket. However, they may require an adjustment period with effects not being noticeable right away.
The side effect profile is similar between these two medications; however notable differences exist - Rapaflo may cause retrograde ejaculation (orgasm with little or no semen), while Uroxatral has lower rates of this side effect but might slightly lower blood pressure more than Rapaflo does. For both drugs, patients should seek medical advice if they experience severe dizziness or fainting spells.
