It is essential to take this medicine exactly as instructed by your doctor or pharmacist. Understanding the appropriate dosage and administration methods will enhance the effectiveness of the treatment. Adhering to prescribed guidelines ensures optimal results and reduces the risk of potential complications.
If you have been prescribed tadalafil through a private prescription, please read the accompanying information carefully, as the dosage and strength may differ depending on your specific health needs. Always consult your healthcare provider if you have any questions regarding your treatment plan.
Dosage and strength
Tadalafil is available in various strengths: 2.5mg, 5mg, 10mg, and 20mg tablets, allowing for flexible dosing based on the individual's requirements. Your healthcare professional will determine the best strength for you.
Dose for erectile dysfunction
The typical dose of tadalafil for erectile dysfunction is 10mg, taken before sexual activity. It is crucial to adhere to the guideline of not exceeding one tablet in a 24-hour period. This precaution is vital to ensure safety and minimize side effects.
Your healthcare provider may adjust your dose based on your response to the treatment and frequency of use. While the effects of tadalafil can last over 24 hours, it is not recommended to take the 10mg or 20mg doses daily without medical advice. This approach helps to maintain the effectiveness of the treatment.
For optimal effectiveness, sexual stimulation is necessary for tadalafil to work appropriately. This combination is essential for achieving the desired results when using the medication.
Dose for benign prostate enlargement
For treating benign prostate enlargement, tadalafil is prescribed in the form of 2.5mg or 5mg tablets, with a usual dose of 5mg taken once daily. This consistency in dosing aids in symptom management and improves patient outcomes.
If you are being treated for both benign prostate enlargement and erectile dysfunction, the recommended dose remains at 5mg. It is crucial to follow your doctor's guidance closely to avoid complications.
Dose for pulmonary hypertension
Tadalafil for pulmonary hypertension is available in 20mg tablets, with a standard dosage of 40mg, which consists of taking two 20mg tablets once a day. This higher dosage reflects the increased need for effective management of this condition.
If you have pre-existing kidney or liver problems, your doctor may opt for a lower starting dose of 10mg or 20mg to ensure your safety and reduce the risk of adverse effects.
Swallow the tablets whole with a drink of water or juice (avoid grapefruit juice, as it interacts with the medication). For erectile dysfunction, consume one tablet at least 30 minutes before planned sexual activity to allow the medication to take effect.
For benign prostate enlargement, you may take your tablet in the morning or evening, though consistency in timing each day is recommended to maintain stable drug levels in your system.
Note that tadalafil tablets for pulmonary hypertension are larger and may be more challenging to swallow. If you encounter difficulties, discuss this with your healthcare provider, who may offer alternatives or solutions.
If you forget to take it
If you forget to take your dose:
- For benign prostate enlargement – take it as soon as you remember, then continue with your regular schedule. This will help ensure the medication remains effective.
- For pulmonary hypertension – take the missed dose within 8 hours if possible. If you remember after 8 hours, skip the missed dose and proceed with the next dose at the usual time. Do not double up on doses.
Avoid taking two doses simultaneously. Do not take an extra dose to compensate for a missed one. This can lead to an increased risk of side effects.
If you frequently forget your doses, consider setting an alarm or asking a pharmacist for advice on alternative strategies to help you remember your medication. Consistent use is crucial for the effectiveness of tadalafil.
