How Do ED Drugs Work: Everything Men Should Know


Erectile dysfunction (ED) is a common condition, but modern ED medications can help a great number of men overcome it swiftly and safely. With commonly prescribed medications like Viagra and Cialis, men have multiple options for treating erectile dysfunction.

In this guide, we will examine how these ED medications function. We’ll also provide advice on how to maximise their benefits while minimising adverse effects.

How do ED pills function?

In the United States, the most common ED medications are:

Cenforce 100

Cenforce 150

All of these medications are FDA-approved and considered safe and effective for treating erectile dysfunction in the majority of men. Medications for erectile dysfunction increase blood flow to the penile.

They are Phosphodiesterase type 5 (PDE5) inhibitors, a class of medicines. These medications inhibit the enzyme PDE5, which relaxes the smooth muscles in the penis’ blood vessels, allowing more blood to circulate and facilitating erection. Inadequate circulation is frequently an indication of erectile dysfunction.

Among the most prevalent causes of ED are:

  • Elevated blood pressure
  • Cardiac disease
  • Diabetes
  • Peronei‚Äôs disease
  • However, there are additional potential causes, such as:
  • Physical sedentary
  • Anxiety
  • Depression
  • Smoking

Since the majority of approved ED medications require a prescription, a physician will determine the best course of treatment based on a patient’s symptoms and overall health.

How quickly do ED medications work?

On average, it takes ED medications about an hour or less to take effect. Some tablets may provide increased blood flow to the penis within 15 minutes, while others may take 30 minutes or longer. In the case of Tadalafil (Cialis), some men may be prescribed a daily dose to facilitate spontaneous and frequent erections. Tadalafil onset of action after a single dose is between 30 and 45 minutes.

It is crucial to remember that ED medications do not always produce instant erections, but rather make it easier to achieve one when sexually aroused. In general, these medications will begin to function within 30 to 60 minutes after ingestion, but there are exceptions. Individual factors such as metabolism, the specific medication, and whether the medication is taken with or without sustenance can affect how long it takes for ED medications to take effect.

If you are experiencing problems with both arousal and erectile dysfunction. It can assist in enhancing libido and erectile function, thereby enhancing your overall sexual health.

How long do ED drugs typically last?

Each of the leading erectile dysfunction medications has a unique duration of action. It is essential to note that everyone will experience the medication differently. In certain instances, a medication may be effective for five hours on one day, but only three hours on the following day.

Different factors, such as consuming the medication on an empty stomach versus with food, may affect the duration of the drug’s effects. However, the duration of action for some of the most prevalent ED medications is as follows:

Sildenafil is efficacious for four to five hours. Tadalafil (Cialis) is one of the longest-lasting ED medications available. Those desiring more spontaneity with their erections will find its duration to be a wonderful advantage. Those who are more sensitive to the side effects of a medication may benefit more from a shortened duration. The duration can vary depending on the dosage and the individual’s metabolism.

How Rapidly Do ED Medications Work?

In the majority of cases, all of the ED medications mentioned in this guide should begin functioning on the first day of use. However, individuals respond variably to various medications. In some instances, it may take time to observe positive results. Here are some of the most common reasons why erectile dysfunction (ED) medications may not work immediately.

A lack of stimulation

The medications for erectile dysfunction do not cause arousal, but they make achieving an erection easier when one is aroused. This means that if a man is not in the mood or is anxious about his performance due to erectile dysfunction, he may not become sufficiently aroused to achieve an erection, even if he is taking medication.

Tension or Anxiety

ED-related anxiety can manifest as a self-fulfilling prophecy. Men must relax and avoid worrying about erectile dysfunction during sex in order to avoid becoming anxious. The medication has a higher chance of being effective if the patient is calm and in a good mood.

Needing a Different Dosage

In some instances, a higher dose of the prescribed medication may be required to attain optimal results. If the prescribed medication is not producing results, consult your physician to determine if a higher dose is required.

Medication for Erectile Dysfunction Side Effects

Despite being safe and effective for the vast majority of men, all ED medications carry certain risks that consumers must be aware of. Clark lists the following as prevalent side effects of ED medications:

  • Headaches
  • Upset stomach
  • Flushing (typically facial)
  • Stuffy or runny nostrils
  • Indigestion
  • Dizziness
  • Backache or muscle ache

Some uncommon and potentially serious side effects that males should report immediately to their doctor include:

  • Alterations in blood pressure
  • Vision impairments or other visual alterations
  • Accelerating cardiac rate
  • Persistent migraine

In extremely rare instances, ED medications may induce priapism, a condition in which blood becomes trapped in the penis, resulting in an erection that lasts four or more hours. Untreated priapism can result in dire consequences, such as amputation or even mortality. However, it is typically readily treatable if caught early. It is essential to consult a physician if you experience any adverse effects while taking ED medication.  Occasionally, a basic dose adjustment may be sufficient to mitigate these side effects. Occasionally, switching to a similar medication can eliminate adverse effects while maintaining the best ED outcome.

What Causes ED Medications to Fail?

Several factors can contribute to the ineffectiveness of medications for erectile dysfunction. Inadequate sexual stimulation, incorrect dosage, incorrect timing of medication ingestion, excessive alcohol consumption, underlying health conditions such as diabetes or cardiovascular disease, and medication interactions may all contribute.

If medications for erectile dysfunction (ED) are not producing the intended results, it is prudent to consult a healthcare professional to explore potential causes and alternative treatments.


Medications for erectile dysfunction are highly effective and secure for the majority of men. Since prescriptions are required, a doctor will work with a patient to find a treatment that has the greatest chance of curing erectile dysfunction. If ED medications are ineffective, men can consider other options to treat erectile dysfunction.

Today, begin enhancing your sexual health to regain your confidence and live the sex life you desire.
