Taking tadalafil as prescribed by your doctor is crucial for maximizing its benefits. Adherence to the prescribed regimen ensures optimal therapeutic outcomes.
If you have a private prescription for tadalafil, ensure you read the accompanying information thoroughly, as strength and dosage instructions may vary.
Dosage and strength
Tadalafil is available in various strengths: 2.5mg, 5mg, 10mg, and 20mg tablets, catering to diverse medical needs.
Dose for erectile dysfunction
For erectile dysfunction, the typical initial dose is 10mg, taken as needed. Do not exceed 1 tablet per day, as your healthcare provider may adjust the dosage based on efficacy and tolerability.
Due to tadalafil's prolonged effects, which can last over 24 hours, taking 10mg or 20mg tablets daily is not recommended without professional guidance.
For optimal results, it is crucial that sexual arousal occurs, as tadalafil facilitates the physiological processes necessary for an erection.
Dose for benign prostate enlargement
For treating benign prostate enlargement, tadalafil is typically prescribed in 2.5mg or 5mg doses, with 5mg being the standard daily intake.
If you are addressing both benign prostate enlargement and erectile dysfunction, a combined daily dosage of 5mg is standard practice.
Dose for pulmonary hypertension
In instances of pulmonary hypertension, tadalafil is commonly available in 20mg tablets. The usual dosage for treatment is 40mg, achieved by taking two 20mg tablets once a day.
Individuals with renal or hepatic impairment may require a reduced initial dose of 10mg or 20mg, emphasizing the importance of medical supervision.
It is advised to swallow the tablets whole with a glass of water or juice, while avoiding grapefruit juice due to its potential interaction.
For erectile dysfunction, take one tablet at least 30 minutes prior to the anticipated sexual activity to ensure adequate absorption and effect.
For benign prostate enlargement, the tablet can be taken at any time of the day, but maintaining consistency in your daily regimen is essential for effectiveness.
If you forget to take it
In case of a missed dose:
- benign prostate enlargement – take the missed dose as soon as you remember, then continue with your usual schedule
- pulmonary hypertension – take the missed dose within 8 hours if possible; otherwise, skip it and resume your standard schedule.
Avoid taking two doses simultaneously. Never double up to make up for a missed dose, as this may increase the risk of side effects.
If you find yourself frequently forgetting doses, consider setting a reminder or consulting a pharmacist for tips on how to improve your adherence to the medication schedule.
If you take too much
Overdosage of tadalafil may result in a range of side effects, including:
- headache
- dizziness
- indigestion
- nasal congestion
- visual disturbances (such as blurred vision)
Urgent advice: Contact 111 for immediate assistance if:
- you have taken more than your prescribed dose of tadalafil

Important information:
In emergencies, do not attempt to drive yourself to the hospital. Arrange for someone else to drive you, or call 999 for ambulance services.
Remember to bring the tadalafil packaging, any remaining tablets, and a comprehensive list of your other medications for the medical team.
