Tadalafil is a widely-prescribed medication indicated for the treatment of erectile dysfunction (ED), benign prostatic hyperplasia (BPH), and pulmonary arterial hypertension (PAH). Adhering to your healthcare provider's instructions is crucial for safe and effective use of this medication.
If you are prescribed tadalafil, it's important to read all provided materials carefully because the dosages and guidelines may vary depending on your specific medical needs.
Dosage and strength of tadalafil 5mg
Tadalafil is dispensed in various strengths, including 2.5mg, 5mg, 10mg, and 20mg tablets. Typically, the 5mg dosage is favored for managing a range of medical conditions effectively.
Typical dose for erectile dysfunction
The most common dose for treating erectile dysfunction with tadalafil is 10mg, taken as needed prior to sexual activity. However, for ongoing management, the 5mg pill can be taken daily, ensuring not to exceed one tablet in a 24-hour period.
Your healthcare provider may modify your dosage based on your response and tolerance to the treatment.
The duration of effectiveness for tadalafil can extend beyond 24 hours; therefore, repeated use of higher daily doses like 10mg or 20mg is not recommended.
Note that sexual stimulation is necessary for tadalafil to work effectively.
Typical dose for benign prostatic enlargement
For benign prostatic enlargement, a daily dose of 5mg is commonly prescribed, taken at the same time each day to optimize therapeutic benefits.
In cases where both benign prostatic enlargement and erectile dysfunction are present, the 5mg tablet may be administered.
Typical dose for pulmonary hypertension
Tadalafil is generally prescribed in higher doses, typically 20mg for patients with pulmonary arterial hypertension.
Some patients may require a total of 40mg, achieved by taking two 20mg tablets once daily.
For patients with renal or hepatic impairments, your clinician may start you on a reduced dose of 10mg or 20mg.
It is critical to swallow tadalafil tablets whole with a full glass of water or juice, but grapefruit juice should be avoided due to potential interactions.
If using tadalafil for erectile dysfunction, it is advised to take the tablet at least 30 minutes prior to anticipated sexual activity.
For benign prostatic enlargement, the tablet can be consumed at any time of the day; regular timing can help maintain even levels of the drug in your system.
Keep in mind that tadalafil tablets prescribed for pulmonary hypertension may be relatively large, which could present challenges for some patients when swallowing.
If you forget to take tadalafil 5mg
In case you forget to take your scheduled dose:
- For benign prostatic enlargement – Take your missed dose as soon as you remember, and then continue with your regular dosing schedule.
- For pulmonary hypertension – If you remember within 8 hours of the missed dose, take it. If more than 8 hours have passed, skip the missed dose and resume your standard dosing schedule.
Do not double up on doses to make up for any missed ones and avoid taking two doses at once.
To enhance adherence to your medication regimen, consider utilizing alarms or consult with your pharmacist for tips to maintain your dosing schedule.

Excessive intake of tadalafil can lead to side effects, including:

Urgent advice: Seek medical help immediately if:
