It's essential to adhere closely to the prescribed instructions from your healthcare provider, whether that's a doctor or pharmacist, when it comes to taking this medication.
If you are using a private prescription for tadalafil, it is crucial to thoroughly read the accompanying information leaflet that comes with your medicine. The specifics regarding strength and dosage can vary considerably between different manufacturers and formulations, so ensure you are fully informed before use.
Dosage and strength
Tadalafil is available in various strengths: 2.5mg, 5mg, 10mg, and 20mg tablets, providing flexibility depending on your treatment needs.
Dose for erectile dysfunction
For most individuals dealing with erectile dysfunction, the standard starting dose is typically 10mg, taken as needed. It is important to remember not to exceed one tablet in any given 24-hour period.
Your healthcare provider may adjust the dosage, increasing or decreasing it based on your reaction to the treatment and how frequently you find yourself needing it.
Since the effects of tadalafil can last longer than 24 hours, taking the 10mg or 20mg tablets on a daily basis is generally not recommended to avoid complications.
For the medication to be effective, it is necessary that you are sexually stimulated, as this aids in the pharmacological action of tadalafil.
Dose for benign prostate enlargement
Tadalafil intended for treating benign prostate enlargement is available as 2.5mg or 5mg tablets, with a recommended usual dose being 5mg daily, taken once.
In cases where you are being treated simultaneously for benign prostate enlargement and erectile dysfunction, the recommended dosage remains at 5mg.
Dose for pulmonary hypertension
For pulmonary hypertension, tadalafil is supplied as 20mg tablets.
The typical dosing guideline for this condition is 40mg, which equates to taking two 20mg tablets once daily.
Should you have pre-existing kidney or liver conditions, your healthcare provider may decide to start you on a lower dose of either 10mg or 20mg to better suit your health status.
To take the tablets correctly, swallow them whole with a glass of water or juice, making sure to avoid grapefruit juice as it can interact adversely with the medication.
If using tadalafil for erectile dysfunction, it’s recommended to ingest 1 tablet at least 30 minutes prior to engaging in sexual activity.
For individuals using the medication for prostate enlargement, you have the flexibility to take your tablet either in the morning or evening; however, consistency is key, so aim to take it at the same time each day.
Be aware that tadalafil tablets for pulmonary hypertension are notably larger in size, which may pose difficulties for some patients when attempting to swallow them.
If you forget to take it
Should you forget a dose:
- For benign prostate enlargement: Take the missed dose as soon as you remember, then continue with your regular dosing schedule.
- For pulmonary hypertension: If it’s within 8 hours of your missed dose, take it as soon as you can. If it’s been longer than 8 hours, skip the missed dose and proceed to your next scheduled dose.
Under no circumstances should you take two doses at the same time, nor should you attempt to compensate for a missed dose by taking an additional tablet.
If you find that you frequently forget doses, consider setting an alarm as a reminder. Additionally, consult your pharmacist for further tips on helpful strategies to ensure you remember to take your medication consistently.
If you take too much
Exceeding the recommended dose of tadalafil can lead to various side effects, which may include but are not limited to:
- Intense headache
- Feeling dizzy or lightheaded
- Experiencing indigestion or stomach upset
- Nasal congestion
- Changes in vision, such as blurriness
Urgent advice: Contact 111 for guidance immediately if:
- You have ingested more than your prescribed dose of tadalafil

Information:
If you find yourself needing urgent treatment and need to go to A&E, do not attempt to drive yourself. Instead, request someone to take you or dial 999 for ambulance services.
Make sure to bring along the tadalafil package or leaflet, any leftover tablets, as well as any other medications you may be taking.
