Since the late 1980s, pharmaceutical companies have been attempting to tackle the issue of erectile dysfunction and its symptoms. Along the way, they have developed drugs that effectively treat erectile dysfunction in various ways, and can be used to treat a variety of other conditions. Currently, there are at least three well-known and FDA-approved types of drugs used mainly to treat erectile dysfunction. These drugs tend to work by lowering blood pressure and relaxing muscles in certain areas of the body.

What Is Dosage and Side Effects of Tadalafil?

The nature of these drugs means that they can sometimes be used to treat other conditions, such as high blood pressure. One of these main drugs is Tadalafil, known in the U.S. as brand name Cialis. While the main competitors on the market all work similarly and treat many of the same conditions, there are key differences in their uses, dosages, and side effects. Knowing these differences is key to selecting the right medication for you. Below is a guide for finding the dosage that is best for you, being able to identify common side effects, and advice for starting use of Tadalafil.

What Is Tadalafil Used For?

Tadalafil is the generic form of Cialis. It is sold most commonly as a tablet, but can also be found as a capsule. Generic Tadalafil has a few main uses: the treatment of erectile dysfunction, to alleviate symptoms of benign prostatic hypertrophy (an enlarged prostate), and to treat pulmonary arterial hypertension (a sort of high blood pressure). It has become a popular method for treating erectile dysfunction specifically because it is the only erectile dysfunction drug that can be taken daily, instead of only before sexual activity. Taking a lower dosage of Tadalafil at the same time every day has been proven to improve overall sexual performance. This removes the need to worry about when you anticipate sexual activity, how long before activity you need to take it, and how long its effects will last for the duration of activity.

Dosage of Tadalafil

The below chart outlines the most common uses and dosages for Tadalafil. It’s important to notice that for its main use, treatment of erectile dysfunction, there are a few different methods for taking the drug. One way is to take Tadalafil before sexual activity (in most cases, this would call for Cialis 10 mg, though this can be adjusted depending on how the body reacts).

Another is to take Tadalafil daily, for overall alleviation of symptoms of erectile dysfunction. In that case, it is recommended that patients start with 2.5mg, taken daily at the same time each day. If this is ineffective, the patient can adjust up to 5mg daily. For treatment of symptoms of pulmonary arterial hypertension, the recommended dosage is 40mg. For treatment of benign prostatic hypertrophy, the recommended dosage is 5mg, taken once daily, at the same time each day. If you do overdose on Tadalafil, it’s important to seek medical attention.

Tadalafil Doses by Usage

Use Dose Frequency
Treatment of erectile dysfunction 10mg to 20mg Just before sexual activity
Treatment of erectile dysfunction 2.5mg to 5mg Once per day
Treatment of pulmonary arterial hypertension 40mg Daily
Treatment of benign prostatic hypertrophy 5mg Daily, taken at the same time each day

For Erectile Dysfunction

For erectile dysfunction, Tadalafil can be taken either daily or just before sexual activity. If taken daily, the recommended dosage is 2.5mg-5mg. It is recommended that if you begin using this method, you start at a lower dose and adjust as needed. If taken before sexual activity, the recommended dosage is 20mg. This can be adjusted anywhere from 10mg to 20mg. Tadalafil lasts the longest of erectile dysfunction medications, so one dosage may be all you need over a number of hours, even days. It’s best to start with one lower dosage and see how your body reacts before taking another dosage in a short time period. For recreational use, one tablet of the average dosage can sometimes last a few days (about 36 hours, on average). It’s best to not take more than one dose daily when being used for recreational use. If it is not effective, simply raise the dosage the next time you take it.

For Pulmonary Hypertension

If taken for pulmonary hypertension (a type of high blood pressure), the recommended dosage is 40mg. This is usually taken in two tablets, as many are sold in tablets of 20mg (since the most common 40mg dose is for erectile dysfunction, and 20mg is the maximum recommended for erectile dysfunction). If you’re just beginning treatment, it can be a good idea to just start with one 20mg tablet for a few days, and build up to 40mg. This dosage can be taken with or without food.

Does Age or Weight Influence on a Dosage?

Most studies have shown that age and weight have little influence on the effectiveness of Tadalafil in properly treating the mentioned conditions. It’s recommended that anyone who wants to begin using Tadalafil daily for erectile dysfunction starts with 2.5mg and adjusts from there. For use just before sexual activity, it is recommended that patients start with 10mg. In all cases of using Tadalafil, the patient can adjust their dosage depending on how the body responds, until they find the Cialis dose that works best for them.

Tadalafil Side Effects

Though Tadalafil is largely successful in treating the mentioned conditions and usually causes no side effects or complications, it is important to understand what possible side effects could occur. There are both common and rare side effects to taking Tadalafil, and depending on severity and frequency, it is a good idea to check with your doctor if you experience any of these. Most common symptoms will go away fairly quickly, and can be amended by adjusting the dosage you are taking. If they persist, speak to a doctor. Depending on your body, there may be minor side effects that will often occur but aren’t cause for worry.


The most common side effects of Tadalafil include:

  • headache;
  • stomach pain;
  • flushing;
  • indigestion;
  • acid reflux;
  • back pain;
  • muscle pain (especially in legs);
  • stuffy or runny nose.

These symptoms usually go away in 24-48 hours if they occur, and relate to how Tadalafil thins blood in the body. These slight discomforts can be very normal, and usually are easily amended by adjusting the dosage of Tadalafil you are taking. If they become especially severe, ask a doctor for advice.


Rarer, more severe side effects of taking Tadalafil include loss of sight and/or hearing, shortness of breath, irregular heartbeat, fainting, red eyes, seizures, and very severe chest or leg pain. If any of these side effects occur, it is important to seek medical attention. The rarest and dangerous side effects often occur as a result of Tadalafil being mixed with a citrate, a base for many other medications, especially those used to treat heart conditions. If you are currently on any citrate medications or are unsure, it’s vital to check with your doctor before taking Tadalafil. Over the long term, Tadalafil (because it is a blood-thinning drug) can have other effects on the body. If you ever begin to notice common changes or reoccurring symptoms, you should check with your doctor.

How Does Tadalafil Work?

Tadalafil is a PDE5 inhibitor, that works to relax the muscles and increase blood flow to targeted areas of the body. Compared to similar drugs, that are used to treat conditions like erectile dysfunction, Tadalafil has a longer half-life, and thus its effects tend to last longer.
