Erection difficulties, commonly referred to as erectile dysfunction (ED), are a prevalent issue in modern times. Recently, there’s been a notable surge in the utilization of oral erection drugs for managing this condition. 

These ED pills, primarily known as phosphodiesterase type 5 inhibitors (PDE5i), have revolutionized the approach to treating penile dysfunction. Globally, these erection pills rank among the most frequently prescribed medications.

Originally developed by leading global corporations, these drugs for penile dysfunction are now produced by numerous companies worldwide. 

In our country, local manufacturers have also begun producing these erection pills, which are readily available in pharmacies.

In this piece, I will delve into the specifics of the PDE5i group, highlighting their role as pivotal erection pills in the oral treatment of erectile dysfunction.


What are the common ED pills utilized for penile dysfunction treatment?

Erection pills, specifically the PDE5i group ED pills, are prominent in managing erectile dysfunction. This category encompasses four major types:

Sildenafil (Viagra): 

This ED pill is best consumed approximately one hour prior to sexual activity. An empty stomach enhances its efficacy. Depending on the severity of penile dysfunction, its effects can persist for 4-5 hours. Dosage options include 25, 50, and 100 mg.

Vardenafil (Levitra): 

Administered between 45 minutes to an hour before sexual engagement, this ed pills can be taken with or without food. However, high-fat meals may impede its absorption. Its effectiveness lasts about 4-5 hours and is available in 5, 10, and 20 mg dosages.

Tadalafil (Cialis, Hardcis): 

This ED pill, effective for a remarkable 36 hours, is taken 1-2 hours before intercourse. Food intake does not affect its absorption. These long-acting ed pills are designed for daily low-dose use or higher doses before sexual activity. Available in 5, 10, and 20 mg.


Suitable for consumption with food or on an empty stomach, it is recommended to take this ED medications about 30 minutes before intercourse. Its effects can last up to 6 hours, and it comes in 50, 100, and 200 mg formulations.

How do PDE5i group ED medications work?

PDE5i group drugs, commonly known as erection pills or ED medications, operate by amplifying the impact of nitric oxide (NO). NO is a vital molecule in the formation of an erection. 

These drugs for penile dysfunction work by relaxing the cavernous smooth muscles inside the penis, which in turn enables the penile vessels to widen and facilitates increased blood flow to the penis. 

The process leads to an erection, primarily due to the enhanced arterial blood flow to the penile area. While these erection pills vary in their structural makeup and the duration of their effects, their fundamental mechanisms of action, pivotal in treating penile dysfunction, are quite similar.

How are erection drugs utilized in treating penile dysfunction?

Erection pills, specifically PDE5i group ED medications, are globally recognized as the primary oral treatment for erectile dysfunction. There are two main methods of using these ED medications:

Pre-Intercourse Usage: 

Typically, these erection pills are taken about an hour before sexual activity. This approach is ideal for individuals with mild erection issues or those seeking to enhance performance.

Long-Term Administration: 

For continuous management of penile dysfunction, low doses of ED pills are preferred. Tadalafil, at a daily dose of 5mg, is often the drug of choice for this purpose. Research indicates that regular use of these erection pills for three months can initiate nocturnal erections and improve overall erectile function. 

This long-term, low-dose treatment is also therapeutically beneficial for individuals with severe erection problems and for penile rehabilitation, yielding highly successful results.

What are the potential side effects of erection pills used in penile dysfunction treatment?

erection drugs

Erection pills, particularly those in the PDE5i group of ED medications, generally have mild side effects. The common side effects of these drugs for penile dysfunction include:


Headaches are a prevalent side effect of ED medications. They occur due to a rapid change in blood flow resulting from heightened nitric oxide levels.

This issue is typical across various ED medications, meaning changing brands might not resolve the problem. If you experience headaches due to your ED medication, it’s important to consult your doctor for advice on managing this side effect.

Muscular Discomfort and Pains Associated with erection pills:

Individuals taking erectile dysfunction (ED) medications may experience muscle aches and pains across their body. Additionally, some report localized pain, particularly in the lower back area. To alleviate these types of discomfort while on ED medication, over-the-counter (OTC) pain relievers might be beneficial.

Nevertheless, it’s crucial to consult with your doctor to rule out other underlying causes of your pain. Your doctor can also advise on choosing an OTC pain medication that is compatible with your ED treatments and any other medications you’re currently taking.

Gastrointestinal Issues from erection drugs

Erectile dysfunction (ED) medications can lead to certain uncomfortable side effects affecting the digestive system, with indigestion and diarrhea being the most common.

To mitigate these minor digestive issues, altering your diet could be beneficial. Opting for water over caffeinated drinks, alcohol, or juices might reduce stomach upset. If dietary adjustments don’t yield results, consider discussing with your doctor about over-the-counter remedies that could be effective.


The heightened levels of nitric oxide in ED medications can sometimes cause dizziness in men. Typically, this dizziness is mild, but it can still be troublesome during daily activities. In rare instances, dizziness from ED medications has led to fainting, which is a significant health concern. It’s important to inform your doctor if you experience dizziness while on these medications. Should you faint while taking them, seek immediate medical attention from your doctor.

Vision Changes:

ED medications can also impact your vision, sometimes leading to temporary changes like blurred vision. These medications are not advised for individuals who have experienced vision loss or have a retinal disorder known as retinitis pigmentosa. If you experience a complete loss of vision or persistent changes in your vision, it could indicate a more severe problem related to your ED medication. In such cases, seek urgent medical care.


Flushes are temporary episodes of skin redness, commonly occurring on the face and possibly extending to other body parts. They can range from mild, such as blotchy skin, to severe, like rashes. While they might cause discomfort due to their appearance, flushes are usually not harmful. However, flushes associated with ED medications can intensify if you consume hot or spicy foods, drink alcohol, or are in warm temperatures.

Congestion and Runny Nose:

Experiencing congestion, or a runny or stuffy nose, is a frequent side effect of ED Drugs. These symptoms typically resolve without specific treatment. If they continue, it’s advisable to consult your doctor.

Less Common and Potentially Serious Side Effects of ED Medications

While minor side effects are typical with erectile dysfunction Erection pills usage, there are less common side effects that can be quite serious. Some of the more severe side effects associated with ED medications include:

  1. Priapism: This is a condition where erections last longer than 4 hours. It requires immediate medical attention to prevent long-term damage.
  2. Sudden Changes in Hearing: This can include a sudden decrease or loss of hearing, which may be accompanied by tinnitus (ringing in the ears).
  3. Vision Loss: This involves a sudden decrease or loss of vision, which can be a sign of a serious medical issue and warrants immediate medical care.

When to talk with a doctor 

If you’re experiencing issues with erectile dysfunction (ED), it’s crucial to consult your doctor. Not only is ED treatable, but it can also indicate underlying health problems. Addressing these underlying causes might also improve ED symptoms.

You should speak with your doctor if you are at risk for, or currently have, any of the following conditions:

  • Diabetes
  • High blood pressure
  • High cholesterol
  • Cardiovascular disease
  • Overweight or obesity
  • Depression or anxiety

Additionally, ED is more prevalent after age 50 and among those who smoke or consume alcohol. Discuss these risk factors with your doctor to determine if ED treatments are suitable for you.

When discussing ED treatments, inform your doctor about all medications you’re taking and other health issues you have. If medications are not suitable for your ED, your doctor might recommend alternative treatments, such as surgery or non-surgery erectile dysfunction treatments.

Should your doctor prescribe ED medications, contact them immediately if you experience any severe side effects. Some individuals are more susceptible to these side effects due to other health conditions or medications they are taking.

Who should avoid using PDE5i group ed pills?

Erection pills, specifically oral ED medications used for penile dysfunction, are widely utilized due to their generally non-serious side effects in healthy individuals. Often, these ED pills are accessible over-the-counter at pharmacies. 

However, in certain cases, the use of PDE5i group drugs for penile dysfunction can lead to serious side effects. Situations where these ED medications should be used with caution or avoided include:

  • Individuals on nitrite-nitrate-containing medications: These are drugs (like nitroglycerin) used for heart-related chest pain (angina). Combining these with ED medications can lead to severe low blood pressure and fainting.
  • Patients with extreme blood pressure conditions: Those with exceptionally low or high blood pressure should exercise caution with these ed pills. It is advisable not to take these ED pills without a doctor’s recommendation.
  • People with significant liver diseases.
  • Patients with kidney failure who are receiving dialysis treatment.

Do drugs for penile dysfunction produce uniform results for all patients? 

The response to this varies. Erection pills, specifically those in the PDE5i group, do not exhibit identical effects in every individual. The efficacy of these ED pills differs based on several patient-specific factors. 

For instance, the impact of these drugs for penile dysfunction is typically reduced in patients who are obese, older in age, lead sedentary lifestyles, or have conditions such as diabetes and hypertension. 

Additionally, individuals who have undergone prostate cancer surgery, those with cardiovascular diseases, and those facing neurogenic issues may also experience less effectiveness from these ed pills.

What factors enhance the efficacy of ed pills for penile dysfunction?

To achieve the best results from ED pills used in treating erectile dysfunction, patients should consider the following:

  1. Engage in regular exercise: Physical activity can significantly boost the effectiveness of these ed pills.
  2. Attain ideal weight, especially for obese patients: Managing weight is crucial for maximizing the impact of ED pills.
  3. Control hypertension: Proper management of high blood pressure is essential for those using these drugs for penile dysfunction.
  4. Manage diabetes mellitus: Effective control of diabetes is key to enhancing the efficacy of ed pills.
  5. Proper dosage and timing: Using these ED pills at the right dose and time can significantly improve their effectiveness.
  6. Address testosterone deficiency: If present, treating testosterone deficiency can aid in the effectiveness of these ed pills.
  7. Follow a doctor’s recommendation: It’s important to use these ED pills under medical guidance for optimal results.

What considerations are essential when taking ed pills for penile dysfunction?

ed pills

The absorption of ED pills is influenced by food and drink intake, which is crucial to consider while using these drugs for erectile dysfunction:

  1. Sildenafil and Vardenafil: These ed pills interact with food, hindering their absorption in the small intestine. Consequently, it’s advisable to take these ED pills on an empty stomach. They should particularly be avoided with fatty foods.
  2. Tadalafil and Avanafil: These ED pills are not impacted by food, allowing them to be taken alongside meals. However, it’s recommended to avoid taking these ED medications with excessively large meals.

Which erection pill is the most effective? 

The performance of these drugs for penile dysfunction is generally comparable across the board. There isn’t a single “best” ED pill suitable for every patient. 

Factors like the duration of the drug’s action (whether it’s short-acting or long-acting), cost, and ease of use play significant roles in determining patient preference for these ED medications. Each individual’s experience and needs dictate which of these erection pills might be the optimal choice for them.

Do ED medications assist in treating prostate enlargement?

erection drugs

Erection pills, particularly ED pills, are employed in the pharmacological treatment of benign prostate enlargement (BPH). They are often used in combination with alpha-blocker drugs. 

We frequently recommend this combined therapy to our patients. Specifically, drugs from the tadalafil group, often in 5mg doses daily, are utilized for this purpose.

The use of PDE5i ED medications in BPH treatment serves two primary objectives:

  1. These drugs for penile dysfunction relax the smooth muscles in the bladder neck and prostate capsule, aiding in comfortable urination for patients.
  2. Additionally, they provide treatment if the patient simultaneously experiences erectile dysfunction along with BPH.

Are erection pills habit-forming? 

The PDE5i group of drugs, utilized for managing penile dysfunction, do not lead to addiction in patients usually.

Notably, individuals who have been using these ED pills over an extended period or for enhancing performance often develop a psychological belief that they might encounter erection issues if they cease taking these ED medications. This concern is more of a psychological effect rather than a physical dependency on the medication.

Are erection pills used in conjunction with ESWT therapy?

Extracorporeal Shock Wave Therapy (ESWT), a form of shock wave therapy applied to the penis, is extensively employed in patients with erectile dysfunction. Research indicates that ESWT treatment proves effective for those who haven’t responded well to ED drugs. 

Post-ESWT treatment, it’s observed that patients experience benefits from these drugs for penile dysfunction. Furthermore, combining ESWT with PDE5i group erection pills has shown more favorable outcomes. In our practice, we administer both ESWT and ED medications together to patients, and the results have been quite positive.

Can erection pills be combined with PRP and stem cell therapies?

ED medications are compatible with PRP (P-shot), SVF, and other stem cell treatments administered to the penis. It’s been demonstrated that using these drugs for penile dysfunction in conjunction with such restorative or regenerative therapies enhances their effectiveness. 

The synergistic use of ED pills with these advanced treatments tends to yield more efficacious results.

Do erection pills affect sperm negatively?

ED medications, often utilized by young individuals and men desiring to conceive, raise common concerns about their potential adverse effects on sperm and the risk of infertility. 

However, scientific research indicates that these drugs for penile dysfunction actually have positive impacts on sperm health and do not lead to infertility. Contrary to concerns, ED pills can be beneficial in this regard, offering reassurance to those using these medications.

Can a person switch from one ED drug to another?

Since the effects and mechanisms of action are quite similar across the spectrum of ED drugs, switching from one medication to another within the same group typically poses no issues. 

However, it’s advisable to make such changes under the guidance and supervision of a urologist to ensure the best and safest approach.

Are ED drugs useful for treating female sexual dysfunction?

Trials have been conducted using ED drugs for female sexual dysfunctions, but results show that they are not effective in this context. This conclusion is supported by scientific studies published in internationally respected Urology journals. 

Consequently, the use of these drugs is not recommended for women seeking treatment for sexual dysfunction.

Can erection pills be used by individuals without erection problems for performance enhancement?

A common query is whether these ED drugs are solely for those with erectile issues or if they can boost performance in otherwise normal individuals. 

Indeed, individuals without penile dysfunction can use these ED medications for performance enhancement. However, it’s advised to use these drugs only before sexual activity and not on a prolonged basis.

Do ED pills help with premature ejaculation?

PDE5i group erection pills have also been found effective in addressing premature ejaculation. Our studies, presented at national and international congresses, have shown that ED drugs can alleviate this issue in patients experiencing premature ejaculation. These findings have been published in international medical journals.

Can ED pills be combined with premature ejaculation medications?

Yes, they can be combined. There’s no adverse effect in using ED medications alongside medications for premature ejaculation treatment. In fact, their combined use often yields more effective results in managing premature ejaculation, as evidenced in our studies and published in an international Urology journal.

The Role of ED Pills in Penile Rehabilitation:

PDE5i group drugs, or erection pills, are extensively used in penile rehabilitation following radical prostatectomy surgeries for prostate cancer (whether open, robotic, or laparoscopic). 

These ED medications can be used either alone or in combination with other penile rehabilitation methods. In our practice, we frequently employ this treatment approach for our patients, often preferring low-dose tadalafil group 5 mg drugs for this purpose.

Frequently Asked Questions About ED Medication Side Effects

If you’re concerned about side effects or have specific medical conditions, consider discussing avanafil (Stendra) with your doctor. This second-generation PDE5 inhibitor is known for having a lower rate of side effects compared to older ED medications.

However, if you are taking nitrates for heart conditions, all ED medications could be unsafe due to potential interactions. In such cases, your doctor might suggest alternative treatments like non-surgery or surgical options.

The side effects of ED drugs can vary from person to person, but vardenafil (Levitra), among the first-generation PDE5 inhibitors, is often considered to have fewer side effects.

This might be attributed to its higher potency, which allows for lower effective dosages. Avanafil is another option that tends to have fewer side effects compared to older ED medications.

The most effective treatment for erectile dysfunction (ED) varies depending on the individual’s circumstances, including the underlying cause of the condition, overall health, and personal preferences. It’s important to consult with Istanbul Urology Clinic for a personalized approach.


Erection pills from the PDE5i group represent the foremost choice for oral treatment of penile dysfunction worldwide. To ensure the desired outcomes, their usage should be supervised by a urologist. 

The urologist will determine the suitable dosage, duration, and medication for each patient. In the present day, as these drugs are susceptible to misuse, it is imperative to acquire them from trustworthy sources. 

In instances where ED drugs and alternative non-surgical treatment approaches such as PRP – Shockwaves – Stem cells yield no response, the final recourse may be penile prosthesis surgery.
