Erectile dysfunction is an incredibly common medical condition, affecting more than 30 million men in the United States alone.

Since the introduction of erectile dysfunction prescription medications to the market in the late 1990s, men today have more choices than ever for the treatment of this frustrating condition, but many avoid speaking to their doctors about their symptoms out of embarrassment. 

Although tadalafil, a popular treatment for erectile dysfunction, is only available with a prescription, it is possible to buy both brand name and generic tadalafil online.

We’ve put together a list of the best online sources for Cialis, which is also sold under the generic name of tadalafil.

What is tadalafil?

Tadalafil is the generic version of the PDE5 inhibitor Cialis, and is most well known for its treatment of erectile dysfunction in men.

The medication is sold under the brand names Cialis and Adcirca and works by relaxing the blood vessels and increasing blood flow to certain parts of the body, including the penis. It also works in conjunction with other medications as an alpha-blocker to help improve urinary symptoms caused by BPH. 

When sold under the brand name Cialis, tadalafil is used to treat erectile dysfunction and benign prostatic hyperplasia (enlarged prostate); when sold under the brand name Adcirca, the drug is used to treat pulmonary arterial hypertension and can also improve exercise capacity when used in both men and women. 

Tadalafil is one of the most popular medications to help with sexual stimulation in men and is available by prescription only due to its potential to cause serious side effects in patients with certain medical histories.

How do I use tadalafil to treat sexual dysfunction?

Unlike sildenafil (generic Viagra), tadalafil can be taken either daily or on an as-needed basis for the treatment of sexual dysfunction.

Therefore, how a patient chooses to use the medication to treat sexual dysfunction depends on their specific lifestyle, needs, and budget.  

Men who want to have sex spontaneously and frequently may choose to take tadalafil daily.

The medication can be taken with or without food and at any time of day, but patients should not take more than one pill every 24 hours.

The drug can also be taken on an as-needed basis about 30 minutes prior to sexual activity, similar to Viagra.

Note that tadalafil does not protect against sexually transmitted disease.

While some patients find that planning out sex is difficult or impossible, this option works well for patients with a limited budget, since the drug will remain in your system for up to 36 hours and can provide the desired effect even if taken well before intercourse. 

Are there any side effects associated with tadalafil?

Most people tolerate tadalafil well, but the medication can cause some side effects.

The side effects most commonly associated with tadalafil are:

  • Stuffy or runny nose
  • Headache
  • Difficulty falling asleep or staying asleep
  • Back pain
  • Upset stomach
  • Flushing (feeling of warmth)
  • Indigestion
  • Pain in the limbs
  • Muscle aches

Medical attention should be sought immediately if any of the following side effects occur during sexual activity:

  • Dizziness
  • Numbness, tingling, or pain in the jaw, arms, chest, or neck
  • Nausea

Other rarely reported, but serious, side effects requiring immediate medical attention include:

  • Priapism - erections lasting longer than four hours
  • Sudden hearing decrease, hearing loss, or ringing in the ears
  • Sudden vision loss in one or both eyes, which is a symptom of a serious eye problem called non-arteric anterior ischemic optic neuropathy (NAION)

Who should not take tadalafil?

Tadalifil is a prescription medication due to its potential to cause dangerous side effects in certain groups of people.

For this reason, any online provider will require a prescription for the medication.

If you are not required to speak with a healthcare provider to seek medical advice and obtain a prescription, you are likely receiving counterfeit tadalafil that could be potentially dangerous at worst and ineffective at best. 

Individuals with any of the following conditions should not take tadalafil unless approved by their physician:

  • Heart problems like irregular heartbeat, angina, or history of any kind of heart disease like heart attack
  • Sickle cell anemia, multiple myeloma, hemophilia, leukemia, or another blood disorder
  • Liver or kidney disease
  • Structural deformity of the penis, such as Peyronie’s disease
  • Stomach ulcer
  • Retinitis pigmentosa
  • High blood pressure / low blood pressure
  • Those taking nitrates to manage chest pain
  • Congestive heart failure or stroke within the last six months, or myocardial infarction within the last three months
  • Any health condition for which they have been advised not to have sexual intercourse
  • Anyone using isosorbide, nitroglycerin, amyl nitrate
  • Those taking doxazosin or tamsulosin should consult with a physician about using these with tadalafil

Best Online Sources for Cialis

Erectile dysfunction can be tough to talk about, and scheduling a trip to the doctor’s office is less than convenient, especially during a pandemic.

Because Cialis is only available by prescription due to its potential to cause serious side effects, you’ll need to consult with a doctor before getting a prescription for the drug.

However, thanks to a number of new online telehealth providers and subscription services, it has never been easier to get the medication you need.


Hims is a men’s healthcare and personal wellness company that strives to make it easier than ever for men to take care of themselves and their bodies.

Using the Hims app or website, you’ll create a profile that includes information about your medical history, symptoms, general health, and lifestyle.

In order to ensure that your doctor is treating you and not someone else, you’ll also supply your government-issued ID card, like a driver’s license, and a credit card, all of which are stored on a secured, encrypted platform.

Once your information has been entered, you’ll be virtually connected with a licensed healthcare provider in your state who will talk to you about your diagnosis and potential treatment options.

If your diagnosis and medical history warrants a prescription, your doctor will write a prescription for the medication you need, such as Cialis, and your medications will be shipped to you discretely by mail.

Each of your doses will be either individually wrapped or in a bottle, depending on the medication that is prescribed.

In addition to the convenience associated with medication shipped directly to your door, Hims helps you avoid an in-person trip to the doctor’s office and the copay that comes with it.

You can also be confident that you’re receiving genuine Cialis or its generic equivalent, tadalafil, if you choose.

Cialis and other erectile dysfunction medications are frequently counterfeited and sold through unscrupulous online retailers, so finding an online source you can trust, like Hims, is key.

Tadalafil is available from a cost of 240 dollars per month for daily use through Hims, compared to Cialis, which costs 570 dollars per month for daily use.
