It's crucial to take this medication according to the guidance provided by your healthcare professional, be it a doctor or pharmacist.
When you receive a private prescription for tadalafil, ensure you thoroughly read the accompanying information that comes with your medication. The strength and dosage specifics may differ from one person to another.
Dosage and strength
Tadalafil is available in various strengths: 2.5mg, 5mg, 10mg, and 20mg tablets.
Dose for erectile dysfunction
For erectile dysfunction, the typical starting dose of tadalafil is 10mg, which should be taken as needed. It is important to never exceed one tablet within a 24-hour period.
Your doctor may adjust your dosage based on the medication's effectiveness and your response to it.
Note that the effects of tadalafil may persist beyond 24 hours; hence, daily consumption of the 10mg or 20mg tablets is generally not advised.
To maximize the efficacy of the tablet, ensure you are sexually stimulated.
Dose for benign prostate enlargement
For those needing treatment for an enlarged prostate, tadalafil is available in 2.5mg or 5mg dosages, with the standard recommendation being 5mg taken once daily.
Patients dealing with both benign prostate enlargement and erectile dysfunction typically take a 5mg dose.
Dose for pulmonary hypertension
In the case of pulmonary hypertension, tadalafil is offered in 20mg tablets.
The usual prescribed dosage is 40mg, which involves taking two 20mg tablets once each day.
If you have pre-existing kidney or liver issues, your healthcare provider may reduce the initial dose to 10mg or 20mg.
Make sure to swallow the tablets whole with a drink of water or juice, avoiding grapefruit juice as it can interfere with the medication.
For erectile dysfunction, it is recommended to take a tablet at least 30 minutes before engaging in sexual activities.
If you are using tadalafil for prostate enlargement, you have the flexibility to take it either in the morning or at night; however, consistency in timing is ideal.
Keep in mind that tadalafil tablets used for pulmonary hypertension are relatively large and may present difficulty in swallowing for some patients.
If you forget to take it
In the event you miss a dose:
- For benign prostate enlargement – take your dose as soon as you recall, then resume your usual schedule.
- For pulmonary hypertension – if possible, take it within an 8-hour window. If over 8 hours have passed, skip that dose and return to your regular dosing schedule.
Avoid taking two doses at once and refrain from using extra medicine to compensate for a missed dose.
If forgetting doses is a recurring issue, setting an alarm may help. Additionally, consult a pharmacist for tailored strategies to assist you in remembering your medication.
If you take too much
Overconsumption of tadalafil can lead to adverse effects such as:
- headaches
- dizziness
- indigestion
- nasal congestion
- visual disturbances, including blurred vision
Urgent advice: Contact 111 for assistance immediately if:
