It's absolutely crucial to take this medicine as directed by a healthcare professional, such as your doctor or pharmacist, to ensure optimal results.
If you receive a private prescription for tadalafil, it is essential to thoroughly read the accompanying information that comes with your medication. The strength and detailed dosage instructions can differ based on individual needs and prescriptions.
Dosage and strength
Tadalafil is available in several strengths: 2.5mg, 5mg, 10mg, and 20mg tablets, each designed to meet different patient requirements.
Dose for erectile dysfunction
The recommended initial dose of tadalafil for treating erectile dysfunction is typically 10mg when needed. It is advised not to exceed more than one tablet in a 24-hour period.
Your prescribing doctor may decide to adjust your dosage based on your response to the treatment and how frequently you are taking the medication.
Bear in mind that the effects of the medication may last longer than 24 hours, which is why daily use of the 10mg or 20mg tablets is generally not recommended.
To ensure that the tablet works effectively, it is important that you are sexually stimulated at the time of taking the medication.
Dose for benign prostate enlargement
When prescribed for an enlarged prostate, tadalafil is available in 2.5mg or 5mg strengths. The usual recommended dose is 5mg, taken once daily to help manage symptoms.
If you are treating both benign prostate enlargement and erectile dysfunction concurrently, the recommended dose remains at 5mg.
Dose for pulmonary hypertension
For the management of pulmonary hypertension, tadalafil is available in 20mg tablets specifically formulated for this condition.
The typical prescribed dose for pulmonary hypertension is 40mg, which equates to two 20mg tablets taken once a day.
However, if you have any pre-existing kidney or liver conditions, your healthcare provider might opt to reduce your starting dose to either 10mg or 20mg.
When taking the tablets, ensure that you swallow them whole with a full glass of water or juice (just avoid grapefruit juice, as it may interact negatively).
For those using tadalafil for erectile dysfunction, it’s advisable to take one tablet at least 30 minutes prior to engaging in sexual activity for it to be effective.
If taking tadalafil for prostate enlargement, you can choose to take your tablet either in the morning or evening, but consistency is key — try to take it at the same time every day for best results.
Please note that tadalafil tablets used for pulmonary hypertension are significantly larger and may pose a challenge for some individuals to swallow easily.
If you forget to take it
If you happen to forget a dose of tadalafil, the actions you should take depend on the specific condition you are treating:
- For benign prostate enlargement: Take the tablet as soon as possible upon remembering, then continue with your usual dosing schedule thereafter.
- For pulmonary hypertension: Attempt to take it within 8 hours of your missed dose. If you recall after this time frame, skip the missed dose and return to your regular dosing routine.
Do not attempt to take two doses at once, and never compensate for a missed dose by taking an extra pill.
If you frequently forget your doses, consider setting a daily alarm to serve as a reminder. Additionally, consulting with your pharmacist for strategies that can assist in remembering your medication regimen could be beneficial.
If you take too much
Overdosing on tadalafil can lead to several potential side effects, which may include:
- headache
- dizziness
- indigestion
- stuffy nose
- visual disturbances (such as blurred vision)
Urgent advice: Reach out to 111 for immediate assistance if you experience:
- an instance of having taken more than your prescribed amount of tadalafil
