It is essential to take tadalafil exactly as instructed by your healthcare provider. This adherence ensures its effectiveness and minimizes the risk of side effects.
When you receive a private prescription for tadalafil, take the time to thoroughly read the accompanying informational leaflet. The instructions regarding strength and dosage may differ based on individual health requirements.
Dosage and strength
Tadalafil is available in several strengths including 2.5mg, 5mg, 10mg, and 20mg tablets.
Dose for erectile dysfunction
Typically, the recommended starting dose for erectile dysfunction is 10mg, taken as needed. It is crucial not to exceed one tablet per day.
Your healthcare provider may adjust your dosage based on efficacy and your frequency of use. Therefore, it is important to follow their guidance closely.
Due to the potential for prolonged effects, tadalafil is not usually advised for daily use in the higher doses of 10mg or 20mg.
For optimal effectiveness, sexual arousal is necessary for the medication to work.
Dose for benign prostate enlargement
For individuals with benign prostate enlargement, tadalafil is generally available in 2.5mg or 5mg formats, with a typical dose being 5mg once daily.
If you are undergoing treatment for both benign prostate enlargement and erectile dysfunction, the recommended dose remains at 5mg.
Dose for pulmonary hypertension
For the treatment of pulmonary hypertension, tadalafil is prescribed in 20mg tablets.
The usual regimen includes two 20mg tablets, administered once per day, totaling 40mg.
In cases of liver or kidney issues, your doctor might lower the initial dosage to either 10mg or 20mg to ensure safety.
To take your tablets effectively, swallow them whole with a glass of water or juice, steering clear of grapefruit juice which may interfere with the medication.
For erectile dysfunction, take one tablet at least 30 minutes ahead of anticipated sexual activity for the best results.
If you are using tadalafil for prostate enlargement, you have the flexibility to take it in the morning or evening, though consistency is key; try to take it at the same time each day.
Note that tadalafil tablets prescribed for pulmonary hypertension are relatively large, which may pose a challenge for some individuals.
If you forget to take it
In the event that you miss a dose, the following guidelines apply:
- benign prostate enlargement: Take the missed dose as soon as you remember, then return to your regular schedule.
- pulmonary hypertension: If you recall within 8 hours, take it immediately. If more than 8 hours have passed, skip the missed dose and continue with your regular dosing schedule.
Do not take two doses simultaneously and avoid trying to make up for a missed dose by taking extra. If you frequently overlook taking your medication, consider setting alarms to remind you or consult your pharmacist for helpful strategies.
If you take too much
Overdosing on tadalafil can lead to several side effects which may include:
- headache
- dizziness
- indigestion
- stuffy nose
- visual disturbances such as blurred vision
Urgent advice: Contact 111 for immediate assistance if you
- have taken more than your prescribed dose of tadalafil
