Tadalafil is a widely used generic medication known for its role in treating erectile dysfunction (ED) and providing therapeutic benefits for various other medical conditions in adult males. Often recognized as the active ingredient in the well-known brand Cialis, tadalafil mechanism focuses on enhancing blood flow to the penis, thus supporting men in achieving and sustaining an erection during sexual stimulation. Beyond erectile dysfunction, tadalafil also offers relief for symptoms linked to benign prostatic hyperplasia (BPH) and serves as a treatment option for pulmonary arterial hypertension (PAH). The successful application of tadalafil can significantly improve the quality of life for individuals dealing with these health concerns.
The Food and Drug Administration (FDA) has sanctioned the use of tadalafil for the following medical indications:
- Management of erectile dysfunction (ED)
- Relief from benign prostatic hyperplasia (BPH), commonly referred to as enlarged prostate
- Combined treatment approach for both ED and BPH
- Treatment of pulmonary arterial hypertension (PAH)
This article aims to explore the specific dosages of tadalafil, while also outlining its various forms, strengths, and guidelines for proper administration. For further details, consider reviewing reliable medical sources.
Note: The dosages included herein reflect standard practices recommended by the manufacturer. Always follow the specific dosage instructions provided by your healthcare provider.
The following section provides insight into the recommended dosages for tadalafil.
Tadalafil Form
Tadalafil is offered in an easy-to-swallow oral tablet formulation.
Tadalafil Strengths
The medication is available in four distinct strengths:
- 2.5 milligrams (mg)
- 5 mg
- 10 mg
- 20 mg
Typical Dosages
Your healthcare provider will typically initiate treatment with a lower dose of tadalafil and may gradually adjust it based on individual response to the medication. The primary aim is to identify the smallest effective dosage that achieves the desired therapeutic outcome.
Outlined below are the common dosages recommended for different indications. However, strictly adhere to the unique dosage prescribed by your healthcare professional.
Dosage for Erectile Dysfunction (ED)
For the management of erectile dysfunction, two primary dosing regimens are available: once daily and as needed.
Once Daily: If prescribed a daily regimen, the initial dose is frequently set at 2.5 mg. Depending on individual response and tolerability, your physician may raise the dose to a maximum of 5 mg for daily administration.
As Needed: When taking tadalafil on an as-needed basis for ED, the initial dose is generally 10 mg, taken shortly before anticipated sexual activity. If this initial dose does not yield satisfactory results, your physician may increase it to the maximum limit of 20 mg within a 24-hour timeframe.
If side effects occur with the 10 mg dose, your doctor may suggest reducing the dose to 5 mg before engaging in sexual activity. For additional information on potential side effects, refer to the “Side Effects” section of the complete article.
Dosage for Benign Prostatic Hyperplasia (BPH)
Tadalafil is also utilized in the treatment of symptomatic benign prostatic hyperplasia (enlarged prostate). The standard beginning dosage for this condition is 5 mg, taken once daily. The maximum dose for BPH also remains 5 mg per day.
In conjunction with tadalafil, healthcare providers may prescribe finasteride (Proscar) to optimize treatment effects.
For inquiries about your specific dosage, always consult your healthcare provider.
Dosage for ED and BPH
Patients exhibiting both erectile dysfunction and benign prostatic hyperplasia should start with a dosage of 5 mg of tadalafil, administered once a day, paralleling the dose for BPH alone.
It is essential to discuss your dosage and treatment options thoroughly with your healthcare professional.
Dosage for Pulmonary Arterial Hypertension (PAH)
To treat pulmonary arterial hypertension, physicians generally initiate treatment with a dosage of 40 mg of tadalafil, given once daily. This typically involves taking two 20 mg tablets at the same time.
The upper limit for PAH is set at 40 mg per day.
For any clarifications or concerns regarding your dosage for PAH, engage in a conversation with your doctor for tailored guidance.
How to Take Tadalafil
Tadalafil should be taken as an oral tablet, which must be swallowed whole. Patients are advised against splitting, crushing, or chewing the tablets. Tadalafil can be consumed with food or on an empty stomach, providing flexibility for the patient’s routine.
For those on a once-daily regimen, it is recommended to take tadalafil at the same time each day to maintain stable drug levels in the body, thereby enhancing its efficacy.
For patients prescribed tadalafil on an as-needed basis, it is vital to discuss the timing of your dose with your healthcare provider. Tadalafil supports sexual activity anywhere from 30 minutes post-ingestion to 36 hours after taking the medication.
Note: Taking tadalafil more than once in a 24-hour period is prohibited.
Length of Treatment
Tadalafil may be indicated for either short-term or long-term treatment, contingent upon the particular condition it is addressing and the medical plan established by your healthcare provider.
For benign prostatic hyperplasia and pulmonary arterial hypertension, tadalafil can often be a long-term therapeutic solution. However, if used alongside finasteride for BPH management, the duration for tadalafil may be limited to 26 weeks. Explore additional treatment alternatives for BPH and PAH.
Conversely, tadalafil may be employed as a temporary measure for erectile dysfunction should the underlying cause be identified and resolved. Alternatively, it can also serve as a long-term strategy for ongoing management.
Your healthcare provider will discuss the treatment plan in detail prior to initiating tadalafil therapy, addressing any queries you have concerning the duration of treatment tailored to your individual circumstances. For further insights, refer to our article on tadalafil treatment.
The following are commonly asked questions regarding tadalafil dosages.
What Should I Do for a Missed Dose of Tadalafil?
If you miss a dose of tadalafil, take it as soon as you remember. If the time for your next scheduled dose is approaching, skip the missed dose and continue with your regular medication schedule. Never take two doses to make up for one missed dose. To help prevent missed doses, consider setting up a medication reminder system, such as an alarm or placing notes in visible locations. Smartphone applications can also assist in managing your medication regimen.
When is 60 mg of Tadalafil Prescribed?

- ED: 20 mg as needed prior to sexual engagement
- BPH: 5 mg taken once a day
- PAH: 40 mg administered once daily
