It's crucial to follow the guidance of a healthcare professional when taking this medication. Tadalafil is primarily indicated for the treatment of erectile dysfunction, but it is also beneficial for conditions such as pulmonary hypertension and benign prostatic hyperplasia.
If you possess a private prescription for tadalafil, ensure you read the accompanying documentation thoroughly. The recommended dosage and strength may differ based on your specific health needs and circumstances.
Dosage and strength
Tadalafil is available in various strengths including 2.5mg, 5mg, 10mg, and 20mg tablets.
Dosage for erectile dysfunction
Typically, the recommended initial dose for erectile dysfunction is 10mg, taken as necessary. It is critical to refrain from exceeding one tablet in a 24-hour period.
Your healthcare provider may adjust your dosage based on your response to the medication and how often you use it.
Due to the prolonged effects of tadalafil, doses of 10mg or 20mg are not suitable for daily administration.
Remember, for tadalafil to be effective, there must be sexual stimulation.
Dosage for benign prostatic hyperplasia
In cases of benign prostatic hyperplasia, tadalafil is usually prescribed at strengths of either 2.5mg or 5mg, with 5mg being the standard daily dosage.
For patients managing both benign prostatic hyperplasia and erectile dysfunction, a common combined total dosage is 5mg.
Dosage for pulmonary hypertension
For treating pulmonary hypertension, tadalafil is generally offered in 20mg tablets. A typical regimen involves taking 40mg (two 20mg tablets) daily.
Individuals with kidney or liver issues may require dosage modifications, starting at either 10mg or 20mg.
Tablets should be swallowed whole with a sufficient amount of water or juice; however, grapefruit juice should be avoided due to potential interactions.
For erectile dysfunction, it is advised to take 1 tablet at least 30 minutes prior to engaging in sexual activity.
For benign prostatic hyperplasia, you may take the tablet at any time, but maintaining a consistent schedule is recommended.
Please note that the tadalafil tablets prescribed for pulmonary hypertension may be larger and more challenging to swallow.
If you forget to take it
In the event that you miss a dose:
- For benign prostatic hyperplasia: Take it as soon as you remember, then continue with your regular dosing schedule.
- For pulmonary hypertension: Take the missed dose within 8 hours if possible. If more than 8 hours have elapsed, skip the missed dose and resume your regular dosing schedule.
Never take two doses at once, and do not compensate for a missed dose by taking an additional tablet.
If you frequently miss doses, setting reminders or consulting a pharmacist for aids to enhance memory could be beneficial.
If you take too much
Overdosing on tadalafil may lead to several side effects, including:
- headaches
- dizziness
- indigestion
- nasal congestion
- visual disturbances (such as blurred vision)
Urgent advice: Seek immediate guidance by contacting 111 if:
- you have ingested more than your prescribed dose of tadalafil
