It’s critical to follow the guidance provided by your healthcare professional when taking this medication. Adherence to the prescribed regimen is essential for the effectiveness of tadalafil.
If you possess a private prescription for tadalafil, familiarize yourself with the accompanying information. The recommended dosage and strength may differ from what you're accustomed to if you've taken similar medications in the past.
Dosage and strength
Tadalafil is available in various forms: 2.5mg, 5mg, 10mg, and 20mg tablets. Each strength serves specific medical needs and should be selected based on your doctor's advice.
Typical dosage for erectile dysfunction
For erectile dysfunction, a standard initial dose of tadalafil is 10mg, typically taken as needed. It’s important not to exceed one tablet per day to avoid any adverse reactions.
Your healthcare provider may adjust your dosage based on your response to the medication and any side effects experienced. This customization is vital for optimizing treatment efficacy.
Note that the effects of tadalafil can persist for more than 24 hours, which is why daily intake of the 10mg or 20mg tablets is not recommended.
For maximum effectiveness, a sexual stimulus is necessary when using tadalafil for erectile dysfunction.
Dosage for benign prostate enlargement
When prescribed for benign prostatic hyperplasia (BPH), tadalafil comes in the form of 2.5mg or 5mg tablets. The usual starting dose is 5mg, taken daily.
In cases where patients are being treated for both BPH and erectile dysfunction, the recommended dosage remains at 5mg.
Dosage for pulmonary hypertension
For pulmonary hypertension treatment, tadalafil is administered as 20mg tablets.
The standard dosages are typically 40mg, achieved by taking two 20mg tablets once a day.
If you have existing kidney or liver issues, your doctor may choose to start you on a lower dose of 10mg or 20mg.
Swallow your tablets whole, accompanied by a beverage such as water or juice (just avoid grapefruit juice).
For erectile dysfunction, it’s advisable to consume 1 tablet at least 30 minutes prior to engaging in sexual activity.
When taking tadalafil for prostate enlargement, you can choose to take it in the morning or evening, but try to establish a consistent routine by taking it at the same time every day.
Be aware that tadalafil tablets prescribed for pulmonary hypertension may be larger than other medications, making them harder to swallow.
If you forget to take it
If you forget a dose, act accordingly:
- For benign prostate enlargement: Take it as soon as you remember and return to your regular schedule.
- For pulmonary hypertension: If you recall within 8 hours, take it; otherwise, skip the missed dose and continue as normal.
Under no circumstances should you double your doses or take two at once to compensate for a missed one.
To aid in remembering your doses, consider setting a daily alarm. Additionally, consulting with a pharmacist may offer insights into effective reminders to ensure you take your medicine as prescribed.
If you take too much
Overconsumption of tadalafil may lead to side effects, including:
- headaches
- dizziness
- indigestion
- nasal congestion
- visual disturbances (such as blurred vision)
Urgent advice: Contact 111 immediately if:
