Taking tadalafil correctly is vital for ensuring its effectiveness and your safety. Always follow the guidance provided by your healthcare provider.
If you receive a private prescription for tadalafil, thoroughly review the accompanying information leaflets. Keep in mind that the strength and dosage instructions may differ based on individual circumstances.
Dosage and Strength
Tadalafil is available in several strengths including 2.5mg, 5mg, 10mg, and 20mg. The strength prescribed may depend on the specific condition being treated.
Dose for Erectile Dysfunction
The common dose of tadalafil for erectile dysfunction is 10mg, to be taken as needed. However, it's crucial not to exceed one tablet in a 24-hour period.
Your healthcare provider may adjust your dose based on how you respond to the medication and your tolerance levels.
Effects can last beyond 24 hours; therefore, daily intake of higher doses (10mg or 20mg) is not recommended.
In order for tadalafil to work effectively, sexual stimulation is necessary.
Dose for Benign Prostate Enlargement
For patients with benign prostate enlargement, tadalafil is typically prescribed in 2.5mg or 5mg strengths. The recommended dose is usually 5mg taken once daily.
Individuals being treated for both prostate enlargement and erectile dysfunction often take a combined dose of 5mg.
Dose for Pulmonary Hypertension
For pulmonary hypertension, tadalafil is provided in a 20mg tablet strength.
The usual prescribed dose for this condition is 40mg (two 20mg tablets) taken once daily.
Patients with kidney or liver complications may require a reduced starting dose, typically 10mg or 20mg.
Swallow the tablets whole, accompanied by a glass of water or juice, but avoid grapefruit juice as it can interfere with medication absorption.
For erectile dysfunction, it is advisable to take the tablet at least 30 minutes before engaging in sexual activity.
If using tadalafil for prostate enlargement, you have the flexibility to take it in the morning or at night, although consistency in timing each day is recommended for optimal results.
Tadalafil tablets for pulmonary hypertension are relatively larger and may pose a challenge for those who have difficulty swallowing pills.
If You Forget to Take It
In case you miss a dose:
- For benign prostate enlargement – take the missed dose as soon as you remember, then continue with your regular schedule.
- For pulmonary hypertension – aim to take it within 8 hours of the missed dose. If over 8 hours have passed, do not take the missed dose; instead, return to your regular dosing schedule.
Avoid taking two doses simultaneously, and do not attempt to make up for a missed dose thereafter.
Frequent missed doses might necessitate setting an alarm or consulting with a pharmacist for memory aids.
If You Take Too Much
An overdose may lead to side effects, which can include:
- Headache
- Dizziness
- Indigestion
- Congestion in the nasal passages
- Visual disturbances (for example, blurred vision)
Urgent advice: Contact your healthcare provider immediately if:
- You suspect you have ingested more than your prescribed amount of tadalafil.

Important information:
If you need to go to A&E, do not drive yourself; arrange for someone else to take you or call for an ambulance.
Remember to bring the tadalafil packaging, any leftover tablets, and a list of other medications you are currently taking.
