It's important to take this medicine as advised by a healthcare professional, as this will ensure the treatment is both effective and safe.
If you have received a private prescription for tadalafil, make sure you read all the information provided with your medicine thoroughly, as details regarding strength and dosage can differ significantly based on individual health needs and circumstances. Understanding this information is crucial for your health.
Dosage and strength
Tadalafil is available in several strengths: 2.5mg, 5mg, 10mg, and 20mg tablets, allowing for flexibility in treatment based on the individual's specific condition.
Dose for erectile dysfunction
The typical starting dose of tadalafil prescribed for erectile dysfunction is 10mg, taken as needed before sexual activity; however, it is crucial to take no more than 1 tablet in a 24-hour period for safety reasons.
Your healthcare provider may adjust your dose according to how well the medication is working for you, as well as how frequently you are using it, ensuring optimal management of symptoms.
It’s important to note that the effects of tadalafil can last longer than 24 hours, which is why taking the 10mg or 20mg doses every day is not recommended, to prevent potential side effects.
For tadalafil to be effective, sexual arousal is necessary; taking the medication does not automatically result in an erection.
Dose for benign prostate enlargement
When prescribed for benign prostate enlargement, tadalafil is available in 2.5mg or 5mg tablets, with the standard recommended dose being 5mg, taken once daily.
For individuals managing both benign prostate enlargement and erectile dysfunction, the appropriate dose remains at 5mg, ensuring effective treatment for both conditions.
Dose for pulmonary hypertension
For the treatment of pulmonary hypertension, tadalafil is formulated in 20mg tablets, which are typically prescribed in a dosage of 40mg – this means taking two 20mg tablets once a day.
If you experience kidney or liver issues, your healthcare provider might decide to lower your starting dose to 10mg or 20mg to ensure safety and effectiveness.
When taking your tablets, swallow them whole with a full glass of water or juice; however, avoid grapefruit juice as it can interact with the medication.
If you are using tadalafil for erectile dysfunction, it’s advisable to take one tablet at least 30 minutes prior to sexual activity to allow the medicine to take effect.
For managing prostate enlargement, you can take your tablet either in the morning or evening; however, it’s recommended to take it at the same time each day to maintain even levels in your system.
Be aware that tadalafil tablets for pulmonary hypertension are notably large, which may pose a challenge for some individuals to swallow comfortably.
If you forget to take it
In the event that you miss a dose:
- benign prostate enlargement – take it as soon as you realize, then continue with your regular schedule.
- pulmonary hypertension – attempt to take it within 8 hours. If more than 8 hours have passed, skip the missed dose and return to your regular dosing schedule.
Under no circumstances should you take 2 doses simultaneously, nor should you take an extra dose to compensate for a missed one, as this could result in adverse effects.
If you frequently forget your doses, consider setting an alarm to remind you. Additionally, you may want to consult with a pharmacist for additional strategies that could help you to remember to take your medication on time.
If you take too much
Overdosing on tadalafil may result in a variety of side effects, which can include:
- headache
- dizziness
- indigestion
- stuffy nose
- changes to vision, such as blurred vision
Urgent advice: Contact 111 for immediate assistance if:
- you take more than your prescribed dosage of tadalafil
