Taking tadalafil 2.5 mg tablets exactly as directed by your healthcare professional is crucial for optimal efficacy. Be sure to thoroughly read the patient information leaflet that accompanies your medication, as dosage recommendations can vary significantly depending on individual health conditions and responses to treatment.
Dosage and strength
Tadalafil is available in various formulations, including 2.5 mg, 5 mg, 10 mg, and 20 mg tablets, each designed to address different medical needs.
Dosage for erectile dysfunction
For the treatment of erectile dysfunction, the standard dosage of tadalafil is typically 10 mg, administered on an as-needed basis. It is critical not to exceed one tablet within any 24-hour timeframe.
Your healthcare provider may modify your dosage according to how well it works for you and your tolerance. If the 10 mg dosage suffices, you might find that lower doses of 2.5 mg or 5 mg are more practical for frequent use.
Due to tadalafil's long duration of action, which can extend beyond 24 hours, daily consumption of higher doses is discouraged unless specifically instructed by your healthcare provider.
It's important to note that for tadalafil to achieve its intended effects, sexual arousal must still occur.
Dosage for benign prostate enlargement
When addressing benign prostate enlargement, tadalafil is provided in 2.5 mg or 5 mg doses, with 5 mg typically being the recommended daily intake.
If you require treatment for both benign prostate enlargement and erectile dysfunction, your healthcare provider may prescribe a 5 mg dosage to address both issues effectively.
Dosage for pulmonary hypertension
For the management of pulmonary hypertension, tadalafil comes in 20 mg tablets, with a common dosage being 40 mg, taken once daily, which corresponds to two 20 mg tablets.
Individuals with liver or kidney issues may be advised by their healthcare provider to initiate treatment with a lower dosage, such as 10 mg or 20 mg, to minimize the risk of adverse effects.
It is advisable to swallow tadalafil tablets whole, accompanied by water or juice. Avoid grapefruit juice, as it may interact negatively with the medication.
If you're using tadalafil for erectile dysfunction, make sure to take the tablet at least 30 minutes before you anticipate engaging in sexual activity.
When prescribed for benign prostate enlargement, you may choose a time that suits you best for daily dosing, ideally maintaining a consistent schedule.
It's worth noting that tablets formulated for pulmonary hypertension may be quite large, posing a challenge for some individuals during swallowing.
If you forget to take it
In the event you miss a dose:
- benign prostate enlargement – take the dose as soon as you recall and continue with your regular schedule
- pulmonary hypertension – if you remember within 8 hours, take the dose. If it's been more than 8 hours, skip the missed dose and resume your normal dosing schedule
Never take a double dose to compensate for a missed one. If you frequently forget doses, consider using phone reminders or consulting your pharmacist for effective strategies.
If you take too much
Surpassing the recommended dosage of tadalafil can lead to side effects, which may include:
- headaches
- dizziness or lightheadedness
- upset stomach or indigestion
- nasal congestion
- visual alterations, such as blurred vision

Important information:
If you need to get to an emergency room, do not drive yourself. Seek assistance from someone else or contact 999 for an ambulance.
When going to a medical facility, bring the packaging of your tadalafil, any remaining doses of the medication, and details of any other medications you are using.
