It's crucial to take this medication precisely as directed by your healthcare provider or pharmacist. They will provide guidance tailored to your individual health needs.
If you possess a private prescription for tadalafil, ensure to read thoroughly the accompanying information that is provided with your medication. The prescribed strength and dosage instructions can fluctuate based on your specific medical circumstances.
Dosage and strength
Tadalafil is available in tablet form, with dosages of 2.5mg, 5mg, 10mg, and 20mg tablets accessible for those who need them.
Dose for erectile dysfunction
The standard dose of tadalafil prescribed for erectile dysfunction typically begins at 10mg, taken as needed. It's important to not exceed taking more than one tablet in any given 24-hour period.
Your healthcare provider may decide to adjust your dose higher or lower based on the effectiveness of the treatment and your frequency of use.
The effects of tadalafil can last longer than 24 hours, hence it is not recommended to take the 10mg or 20mg tablets on a daily basis.
For the medication to be effective, it is necessary for you to be sexually stimulated.
Dose for benign prostate enlargement
For those experiencing benign prostate enlargement, tadalafil is available in 2.5mg or 5mg strengths. The typical dose is 5mg, taken once per day, ideally at the same time each day for consistency.
If you are being treated concurrently for both benign prostate enlargement and erectile dysfunction, a dose of 5mg is usually recommended.
Dose for pulmonary hypertension
For treating pulmonary hypertension, tadalafil is dispensed in 20mg tablet strength.
The common dosage for pulmonary hypertension is 40mg, which consists of two 20mg tablets taken once daily.
If you have any kidney or liver concerns, your healthcare provider may opt to start you on a lower dosage, such as 10mg or 20mg, to ensure your safety and adjust as necessary.
Swallow the tablets whole, accompanied by a drink of water or juice, while avoiding grapefruit juice as it can interact with the medication.
For erectile dysfunction, it is advisable to take 1 tablet at least 30 minutes prior to anticipated sexual activity for optimal results.
For benign prostate enlargement, you can take your tablet in the morning or evening, but consistency is key, so try to take it at the same time daily.
Tadalafil tablets intended for pulmonary hypertension are relatively large, which may present difficulties when swallowing. Consider discussing concerns with your pharmacist.
If you forget to take it
If you inadvertently forget a dose, follow these guidelines:
- benign prostate enlargement – take the missed dose as soon as you recall and then continue with your usual schedule
- pulmonary hypertension – aim to take it within 8 hours of the scheduled time. If too much time has passed, skip the missed dose and continue with your next scheduled dose.
Never take two doses simultaneously. Never attempt to compensate for a missed dose by taking an extra tablet.
If you find that you frequently miss doses, setting an alarm to remind you may be beneficial. Additionally, consider seeking advice from a pharmacist on effective strategies to ensure compliance with your medication regimen.
If you take too much
Overdosing on tadalafil may lead to several side effects, including but not limited to:
- headache
- dizziness
- indigestion
- stuffy nose
- changes in vision (such as blurred vision)
