It is crucial to take tadalafil 20mg precisely as prescribed by your healthcare provider. The specific instructions of your doctor or pharmacist should be adhered to closely in order to promote safety and ensure the medication's effectiveness during treatment.
For individuals who possess a private prescription for tadalafil, thoroughly review the accompanying information provided with your medication. This information is vital as the dosage and strength may differ based on your unique health condition and therapeutic needs.
Dosage and strength
Tadalafil is available in an array of strengths, including 2.5mg, 5mg, 10mg, and 20mg tablets, allowing treatment to be tailored effectively.
Dose for erectile dysfunction
For managing erectile dysfunction (ED), a common starting dose of tadalafil is 10mg, taken before anticipated sexual activity. It is vital that you do not exceed more than one tablet within a 24-hour timeframe.
Your healthcare provider may choose to alter your dosage depending on your individual response to the medication and its effectiveness in treating your condition.
The beneficial effects of tadalafil may persist for over 24 hours, thus daily consumption of the 10mg or 20mg dosages is typically not advocated.
For the medication to have the desired effect, it is essential that sexual arousal occurs.
Dose for benign prostate enlargement
In the treatment of benign prostatic hyperplasia (BPH), tadalafil is generally prescribed in lower strengths, with the typical dosage being 5mg taken once daily.
For patients managing both BPH and ED, the advised daily dose remains at 5mg.
Dose for pulmonary hypertension
When treating pulmonary arterial hypertension, a higher strength of tadalafil, typically 20mg, is employed.
The usual dose for this condition is 40mg, which consists of taking two 20mg tablets daily.
If you have renal or hepatic impairment, your healthcare provider may initiate treatment with a reduced dosage, such as 10mg or 20mg, due to potential alterations in the medication's metabolism.
Always swallow the tablets whole, accompanied by water or juice (it is essential to avoid grapefruit juice as it may interact adversely).
For individuals taking tadalafil for erectile dysfunction, it is advisable to take one tablet at least 30 minutes before engaging in sexual activity to enable optimal effectiveness.
For BPH, the time of day you consume the tablet is flexible, whether it be morning or evening, yet consistency in timing is encouraged for optimal results.
Be cautious that tadalafil tablets prescribed for pulmonary hypertension may be larger and may present a challenge for some patients when swallowing.
If you forget to take it
In the event that you miss a dose:
- For benign prostate enlargement – Take the missed dose as soon as you remember. Resume your scheduled dosing thereafter as per your usual regimen.
- For pulmonary hypertension – Ensure you take it within 8 hours following the missed dose. Should more than 8 hours elapse, forgo the missed dose and maintain your standard dosing schedule.
Never double up on doses to make up for a missed one. If you find that you frequently overlook doses, consider employing reminders or consult your pharmacist for additional assistance and strategies.
If you take too much
Overdosing on tadalafil can result in a range of side effects, including:
- Headache
- Dizziness
- Indigestion
- Stuffy nose
- Vision alterations (for instance, blurred vision)
Urgent advice: Reach out to your healthcare provider immediately if:
- You inadvertently consume an amount exceeding your prescribed dose of tadalafil.
