The choice between Tadalafil 5 mg or 20 mg influences the medication’s duration of action in the body, making it important to consider the individual clinical profile. This treatment for erectile dysfunction can be occasional or continuous. Learn more.
Tadalafil 5 or 20 mg are safe medications widely used to treat erectile dysfunction, provided they are prescribed by a physician.
Each dosage has specific indications, which should be adjusted according to the patient’s health conditions and the therapeutic goals defined between doctor and patient.
The final decision between these doses must be evaluated by both the doctor and the patient. Below are some factors to consider. Keep reading!
What Is the Difference Between Tadalafil 5 mg and 20 mg?
The main difference between the two dosages lies in the intensity and duration of effect. Both act similarly in the body, as the active ingredient is the same.
What sets them apart is that a 20 mg concentration provides a more intense and faster effect, indicated for occasional use before sexual activity.
Meanwhile, the 5 mg dose is generally recommended for daily use, ideal for maintaining a more consistent effect.
In situations where a continuous effect is desired, the 5 mg dosage may be considered, always under medical guidance.

Which Tadalafil Dosage Is Best: 5 mg or 20 mg?
The best dosage depends on each patient’s goals and health conditions.
To maintain a constant effect in the body, the 5 mg dose may be recommended. This regimen can be associated with a more predictable response during sexual arousal, in some cases, according to medical evaluation.
On the other hand, the 20 mg dose is more suitable for occasional use and should be taken a few minutes before sexual activity, similar to Sildenafil.
The therapeutic effect of 5 mg Tadalafil lasts for about 24 hours, which is why it is indicated for daily use. Meanwhile, 20 mg Tadalafil lasts around 36 hours, often called the “weekend pill.”
Important to clarify: this does not mean that the man will have an erection throughout the entire period. Rather, while the medication is active, he will be more likely to achieve a good-quality erection when sexually aroused.
Which Tadalafil Can Be Used Daily?
Tadalafil 5 mg was specifically developed for daily use.
This lower dosage can help maintain steady levels of the medication in the body, favoring a more spontaneous response in certain scenarios.
However, the question “Can I take 2 tablets of 5 mg Tadalafil?” is common. The answer depends on medical evaluation, since increasing the concentration in the body may lead to unwanted side effects.
How Does 5 mg Tadalafil Work in the Body?
The medication inhibits phosphodiesterase type 5 (PDE5), an enzyme present in the penile corpora cavernosa. This inhibition increases cGMP levels, a substance that promotes relaxation of smooth muscle and dilation of blood vessels. As a result, more blood flows to the penis during sexual stimulation, making erection easier.
Hence, 5 mg Tadalafil is essentially an erection facilitator. For it to have a practical effect, arousal is required.
Does 5 mg Tadalafil Used Daily Work Forever, or Does the Body Adapt?
According to a 2008 study that assessed the medication’s effectiveness in patients using it long-term, men observed a gradual reduction in response over time.
In some cases, this happened because erectile dysfunction worsened due to associated conditions such as diabetes or cardiovascular problems. In others, the body became accustomed to the medication, potentially reducing the perceived efficacy in certain patients, especially when the clinical condition worsened.
It is important to note that 5 mg Tadalafil does not stop working for all patients. Frequent follow-up and case-by-case evaluation are necessary.
Is It Necessary to Take Tadalafil Forever?
It is not always necessary to take Tadalafil indefinitely in cases of erectile dysfunction.
Continuous use depends on the cause of the dysfunction. If the patient addresses underlying causes, such as controlling diabetes, hypertension, body mass, hormones, anxiety, and even stops using medications like antidepressants, the treatment can be discontinued.
In chronic or vascular-origin cases, use may be prolonged. Intermittent use in specific situations is also possible.
Benefits of Tadalafil for Men’s Health
Tadalafil use may be indicated in certain cases, according to medical evaluation, taking into account its potential effects on the lower urinary tract and erectile function.
Besides helping treat erectile dysfunction, it promotes relaxation of prostate muscle, beneficial in some cases of benign prostatic hyperplasia.
Potential risks linked to Tadalafil should be carefully assessed by a healthcare professional, especially in patients with pre-existing clinical conditions.
When Is the Medication Recommended?
Tadalafil is primarily recommended for men with erectile dysfunction and benign prostatic hyperplasia.
It works by acting on blood vessels, possibly increasing blood flow to the penis in specific situations.
Side Effects of Use
Tadalafil side effects are generally tolerated but can vary among individuals. They include:
- Headaches
- Nasal congestion
- Muscle pain
- Priapism (rare cases)
Indiscriminate use of any dosage can worsen these effects and pose serious risks, such as a severe drop in blood pressure.
Another common question is whether Tadalafil can cause a heart attack. In rare cases, misuse or use by individuals with heart problems may indeed lead to cardiovascular complications, underscoring the need for medical supervision.
Also, be mindful of combining it with other medications, which may intensify adverse effects.
Seek Medical Advice and Avoid Self-Medication
To find out if Tadalafil is right for you, determine the ideal dose, how long you can take 5 mg or 20 mg Tadalafil, and other medication-related questions, you need to consult a specialist.
Although it may be possible to obtain Tadalafil without a prescription, you should not decide on your own, because many factors—such as health history, other medications in use, and cardiovascular status—must be considered before starting this type of treatment.
Therefore, before choosing between Tadalafil 5 mg or 20 mg, consult Dr. Paulo Egydio and avoid self-medication.
Medical advice is crucial for safety and treatment effectiveness, in addition to contributing to improvements in men’s sexual health. There are various treatments for erectile dysfunction, and a specialized urologist can help find the most suitable approach for each case.
