It's important to take this medicine as advised by a doctor or pharmacist. Following the prescribed guidelines ensures optimal effectiveness and safety in using the medication.
If you have a private prescription for tadalafil, read the information that comes with your medicine carefully. The strength and dosage instructions can vary, and it is crucial to follow them precisely to avoid any potential complications.
Dosage and strength
Tadalafil comes as 2.5mg, 5mg, 10mg, and 20mg tablets, allowing for a range of dosages based on individual needs and health conditions.
Dose for erectile dysfunction
The usual dose of tadalafil for erectile dysfunction is typically 10mg when required. It is crucial not to take more than 1 tablet a day to prevent potential adverse effects.
Your doctor may adjust your dose, increasing or decreasing it based on your response to the medication and how often you find yourself needing it.
The effects of tadalafil can last longer than 24 hours, so you are not recommended to take the higher doses of 10mg or 20mg tablets on a daily basis, as it may lead to unwanted complications.
To ensure the tablet works effectively, it is essential that you are sexually excited or stimulated to achieve the desired outcome.
Dose for benign prostate enlargement
Tadalafil for treating an enlarged prostate is available in 2.5mg and 5mg tablets, with the typical effective dose being 5mg, taken once daily for best results.
If you are prescribed tadalafil for both benign prostate enlargement and erectile dysfunction, the recommended dose remains at 5mg.
Dose for pulmonary hypertension
Tadalafil for the treatment of pulmonary hypertension is typically provided in 20mg tablets.
The usual prescribed dose for this condition is generally 40mg, which involves taking two 20mg tablets once daily to maintain effective control of your symptoms.
If you have underlying kidney or liver issues, your healthcare provider might consider reducing your starting dose to 10mg or 20mg for safety reasons.
Swallow your tablets whole with a full glass of water or juice, but be cautious to avoid grapefruit juice, as it can interfere with the medication's effectiveness.
For erectile dysfunction purposes, take 1 tablet at least 30 minutes before the anticipated sexual activity to give it enough time to take effect.
If you are using tadalafil for prostate enlargement, you may take your tablet in either the morning or evening; however, establishing a routine by taking it at the same time each day can enhance reliability.
Tadalafil tablets used for pulmonary hypertension are relatively large and may pose a challenge for some individuals to swallow comfortably, so ensure you drink enough fluid while taking them.
If you forget to take it
If you have:
- benign prostate enlargement – it is advisable to take it as soon as you remember and continue your usual dosing schedule thereafter
- pulmonary hypertension – aim to take it within 8 hours if possible. If you remember after this window, skip the missed dose and resume with the next scheduled dose at the regular time
Never take 2 doses simultaneously, and do not take an additional dose to compensate for a missed one.
If you frequently forget to take your medications, consider setting an alarm as a reminder. Consulting with your pharmacist may also provide helpful strategies tailored to your routine to enhance medication adherence.
If you take too much
Taking excessive amounts of tadalafil can lead to various side effects that may be uncomfortable or concerning, including:
- headache
- dizziness
- indigestion
- stuffy nose
- changes to your vision such as blurred sight
