It’s essential to adhere to the guidelines provided by your healthcare professional, be it a doctor or a pharmacist.
When using a private prescription for tadalafil, it is crucial to read the accompanying documentation meticulously. The specific dosage and strength may differ based on your individual health needs.
Dosage and strength
Tadalafil is available in strengths of 2.5mg, 5mg, 10mg, and 20mg tablets to suit various treatment requirements.
Dose for erectile dysfunction
The recommended starting dose of tadalafil for erectile dysfunction is typically 10mg, taken as needed. It is important to remember not to exceed a maximum of one tablet daily.
Your healthcare provider may adjust your dosage based on your response to the medication and frequency of use, which is essential for ensuring optimal results.
Effects of tadalafil may persist for over 24 hours; thus, it is not advisable to take the 10mg or 20mg tablets on a daily basis.
For the medication to be effective, it is necessary to engage in sexual stimulation, as tadalafil does not work without this.
Dose for benign prostate enlargement
When used to treat an enlarged prostate, tadalafil is typically available in 2.5mg or 5mg tablet forms, with a common dosage of 5mg once daily.
If you are being treated for both benign prostate enlargement and erectile dysfunction, the standard dosage remains at 5mg.
Dose for pulmonary hypertension
For managing pulmonary hypertension, tadalafil is provided in 20mg tablet form.
The usual prescribed dose for this condition is 40mg, which corresponds to taking two of the 20mg tablets once daily.
For patients with kidney or liver impairments, your healthcare provider may decide to lower the initial dose to either 10mg or 20mg to ensure safety and efficacy.
Make sure to swallow the tablets whole, accompanied by water or juice; however, avoid grapefruit juice due to its potential interactions.
For those taking tadalafil for erectile dysfunction, it is advised to consume one tablet at least 30 minutes prior to planned sexual activity.
If you are utilizing tadalafil for prostate enlargement, you have the flexibility to take the tablet either in the morning or evening, although maintaining a consistent time each day is optimal for effectiveness.
Note that tadalafil tablets used for pulmonary hypertension are relatively large; if swallowing poses a challenge, consult your healthcare provider for solutions.
If you forget to take it
If you happen to miss a dose, the following guidelines apply:
- For benign prostate enlargement – take the missed dose as soon as you recall and continue with your usual schedule.
- For pulmonary hypertension – consume the dose within 8 hours of the missed time if possible. If it has been more than 8 hours, skip the missed dose and resume with your next dose at the regular timing.
Do not take two doses simultaneously, and refrain from taking an extra dose to compensate for a skipped one.
If you frequently forget your doses, consider setting a daily reminder alarm. Seeking advice from a pharmacist on strategies to aid memory can also be beneficial.
If you take too much
Overdosing on tadalafil can lead to various side effects, which may include:
- headache
- dizziness
- indigestion
- stuffy nose
- visual disturbances (such as blurred vision)
