Tadalafil is a potent medication primarily used for the treatment of erectile dysfunction (ED), benign prostatic hyperplasia (BPH), and pulmonary arterial hypertension (PAH). It is imperative that tadalafil is taken exactly as directed by your healthcare provider to ensure optimal results. This article aims to provide comprehensive information regarding the appropriate dosage, detailed administration guidelines, and essential precautionary measures for the medication to maximize efficacy while minimizing risks.
Dosage and Strength
Tadalafil is available in several strengths: 2.5 mg, 5 mg, 10 mg, and 20 mg tablets, providing flexibility in management for different conditions.
Dosage for Erectile Dysfunction
In the treatment of erectile dysfunction, the typical starting dosage for tadalafil is 10 mg, taken as needed approximately 30 minutes prior to engaging in sexual activity. Under no circumstances should you exceed one tablet within a 24-hour period without consulting your healthcare provider.
Individual responses to the medication may vary; thus, your healthcare provider may adjust your dosage based on your response and overall health condition.
Tadalafil may remain effective for up to 36 hours post-administration, providing greater flexibility regarding the timing of sexual activity. Due to this extended duration of action, daily dosages of 10 mg or higher are generally not advised for on-demand use.
For tadalafil to elicit its effects, sexual arousal is necessary.
Dosage for Benign Prostatic Hyperplasia
When prescribed for benign prostatic hyperplasia, the commonly recommended dosage is 5 mg taken once daily.
If you require treatment for both erectile dysfunction and benign prostatic hyperplasia, the same recommended dose of 5 mg daily applies.
Dosage for Pulmonary Hypertension
For individuals with pulmonary hypertension, the typical prescribed dosage of tadalafil is 40 mg per day, which can be taken as two 20 mg tablets.
Patients with renal or hepatic impairments may require dosage adjustments, starting at lower strengths such as 10 mg or 20 mg as guided by the healthcare provider.
Administration Guidelines
Tadalafil must be ingested whole with a full glass of water. It is advisable to refrain from consuming grapefruit juice, as this can interfere with the medication’s effectiveness.
If using tadalafil for erectile dysfunction, consume the tablet no less than 30 minutes before engaging in sexual activity.
For benign prostatic hyperplasia treatment, the medication can be taken either in the morning or evening; however, it is important to maintain a consistent dosing schedule, taking it at the same time each day to ensure stability in medication levels.
What to Do If You Forget a Dose
In the event that you miss a dose of tadalafil, follow these guidelines:
- For benign prostatic hyperplasia: Take the missed dose as soon as you remember, then continue with your regular schedule.
- For pulmonary hypertension: If you recall the missed dose within 8 hours, administer it; if more than 8 hours have passed, forgo the missed dose and revert to your usual dosing pattern.
It is crucial not to take two doses simultaneously, nor should you take an extra dose to compensate for a missed one.
What to Do If You Take Too Much
An overdose of tadalafil can culminate in various side effects, which may include:
- Severe headache
- Dizziness or lightheadedness
- Indigestion or upset stomach
- Nasal congestion
- Visual disturbances (e.g., blurred vision)
Urgent advice: Contact your healthcare provider immediately if:
- You have ingested more tadalafil than prescribed.

Important Information:
Do not attempt to drive yourself to the emergency room; it is advisable to have someone else take you or to call for emergency services by dialing 999 if necessary.
When seeking medical attention, bring the tadalafil packaging, any remaining medication, and a comprehensive list of all medications you are currently taking.
Additional Information
Tadalafil has the potential to interact with various medications, including nitrates and certain antihypertensives. Always disclose to your healthcare provider all medications and supplements you are taking to prevent adverse interactions.
Patients with a history of cardiovascular issues, severe hepatic or renal dysfunction, or those frequently engaging in sexual activity should exercise caution and discuss their treatment options with a healthcare professional prior to starting tadalafil.
