It’s crucial to take tadalafil precisely as directed by your doctor or pharmacist. Always follow the instructions provided with your prescription for personalized dosing.
If your tadalafil comes with a private prescription, ensure you read through the accompanying information thoroughly, as strengths and dosage instructions can vary widely among individuals.
Dosage and strength
Tadalafil is available in several strengths including 2.5mg, 5mg, 10mg, and 20mg tablets, providing flexibility based on individual needs.
Typical dose for erectile dysfunction
The standard starting dose of tadalafil for erectile dysfunction is commonly 10mg, which can be taken prior to engaging in sexual activity. However, do not exceed one dosage in a 24-hour period.
Your healthcare provider may adjust your dose depending on its effectiveness and how you respond to treatment. Note that effects can last for over 24 hours, making daily intake of higher doses inadvisable.
To ensure that tadalafil works effectively, you should be sexually stimulated when taking the medication.
Typical dose for benign prostate enlargement
Tadalafil prescribed for benign prostate enlargement often comes in 2.5mg or 5mg dosages. The usual recommendation is 5mg, taken once daily.
If you are addressing both benign prostate enlargement and erectile dysfunction simultaneously, the advised dosage remains at 5mg.
Typical dose for pulmonary hypertension
For those taking tadalafil for pulmonary hypertension, the standard tablet strength is 20mg. Patients typically start with a dose of 40mg, which consists of two 20mg tablets taken once daily.
If you have existing kidney or liver problems, your doctor may opt to lower the initial dose to 10mg or 20mg for your safety.
Always swallow tablets whole with a glass of water or juice, but avoid grapefruit juice, which can interact adversely with tadalafil.
For erectile dysfunction, be sure to take your tablet at least 30 minutes before you intend to have sexual intercourse.
When taking tadalafil for prostate enlargement, you may take it in the morning or evening, but it is best to maintain consistency by taking it at the same time each day.
Note that tadalafil tablets for pulmonary hypertension can be large; if you find them difficult to swallow, consult your healthcare provider for advice.
If you forget to take it
If you miss a dose of tadalafil for:
- benign prostate enlargement: Take it as soon as you remember and then resume your regular schedule.
- pulmonary hypertension: If it's within 8 hours of the missed dose, take it. If more than 8 hours have passed, skip the missed dose and continue with your usual schedule.
Never take two doses simultaneously, nor should you double up to make up for a missed dose.
If forgetting doses is a frequent occurrence, setting an alarm might help. Additionally, asking your pharmacist for other strategies can be beneficial.
If you take too much
Taking excessive tadalafil may lead to a variety of side effects, such as:
- headache
- dizziness
- indigestion
- nasal congestion
- visual changes, including blurred vision
Urgent advice: Contact emergency services if:
- You have ingested more than your prescribed amount of tadalafil.

Information:
If you need to visit an emergency room, do not drive yourself. Arrange for someone else to drive or call for an ambulance by dialing 999.
Be sure to bring the tadalafil packaging or leaflet, any remaining tablets, and any other medications you currently take with you.
