It is of utmost importance to take this medication precisely as directed by your healthcare provider, either a doctor or pharmacist, to ensure safety and effectiveness.
If you have received a private prescription for tadalafil, make sure to thoroughly read the accompanying information that comes with your medicine packet. The strength and dosage recommendations may vary based on individual health considerations.
Dosage and strength
Tadalafil is available in several strengths, provided as 2.5mg, 5mg, 10mg, and 20mg tablets.
Dose for erectile dysfunction
The typical dosage of tadalafil recommended for the treatment of erectile dysfunction is 10mg, which should be taken when needed prior to sexual activity. It is essential to adhere to the guideline of not exceeding more than one tablet in a 24-hour period.
Depending on the efficacy of the medication and your individual response, your doctor may suggest adjustments in either increasing or decreasing your prescribed dose.
Keep in mind that the effects of tadalafil can persist for more than 24 hours; hence, it is not advisable to take the higher doses of 10mg or 20mg on a daily basis.
For the medication to demonstrate its full effectiveness, it is essential for you to be sexually stimulated.
Dose for benign prostate enlargement
When used for the treatment of an enlarged prostate, tadalafil is offered in 2.5mg or 5mg tablet forms. The standard dose is 5mg per day, taken once.
For individuals concurrently receiving treatment for both benign prostate enlargement and erectile dysfunction, the recommended dosage remains at 5mg.
Dose for pulmonary hypertension
In cases of pulmonary hypertension, tadalafil is provided in higher strength tablets of 20mg.
The usual dose for this condition is 40mg, which equates to taking two 20mg tablets, administered once daily.
In patients with kidney or liver impairments, the healthcare provider may opt to lower the starting dose to either 10mg or 20mg to ensure safety.
It is recommended to swallow the tablets whole with a full glass of water or juice, but avoid grapefruit juice as it may interact negatively with the medication.
For erectile dysfunction, it is advisable to consume one tablet at least 30 minutes prior to the anticipated sexual activity for optimal results.
If you are taking tadalafil for benign prostate enlargement, you have the flexibility to take your medication either in the morning or evening, although it is best practice to take it at the same time every day to maintain a steady routine.
Tadalafil tablets designed for pulmonary hypertension are relatively large and may pose challenges for some patients in swallowing.
If you forget to take it
In the event that you miss a dose of tadalafil:
- benign prostate enlargement – take the missed dose as soon as you remember, and then continue with your usual schedule
- pulmonary hypertension – you should take the missed dose within 8 hours of the scheduled time, but if more than 8 hours have elapsed, skip that dose and proceed with your next scheduled dose at the regular time
Under no circumstances should you take two doses simultaneously. Additionally, do not take an extra dose to compensate for a forgotten one.
If forgetting doses becomes a frequent occurrence, consider setting an alarm as a reminder. You may also consult with your pharmacist for additional strategies to help you remember to take your medications consistently.
If you take too much
Excessive intake of tadalafil can lead to a variety of side effects, which may include:
- headache
- dizziness
- indigestion
- stuffy nose
- visual disturbances, such as blurred vision
