It's essential to take this medication as directed by your healthcare provider. If you have a private prescription for tadalafil, make sure to read the information that accompanies your medication carefully, as the strength and dosage instructions may vary significantly from one patient to another.
Dosage and strength
Tadalafil is prescribed in various strengths to accommodate different medical needs, specifically in the following amounts: 2.5mg, 5mg, 10mg, and 20mg tablets. Each strength serves a distinct purpose depending on the condition being treated.
Dose for erectile dysfunction
When treating erectile dysfunction, the typical starting dose of tadalafil is often 10mg, which patients are advised to take as needed. It is crucial to limit intake to one tablet within a 24-hour period to avoid potential side effects.
Your healthcare practitioner may recommend adjustments to this dosage based on your personal response to the medication and how frequently you engage in sexual activity.
The duration of efficacy for tadalafil can extend beyond 24 hours; therefore, daily usage of the 10mg or 20mg strengths is not advised.
Remember, sexual stimulation is necessary for tadalafil to work effectively.
Dose for benign prostate enlargement
For managing symptoms associated with an enlarged prostate, or benign prostatic hyperplasia, tadalafil is typically prescribed in 2.5mg or 5mg doses, with 5mg being the most common daily dosage recommendation.
If you are treating both benign prostate enlargement and erectile dysfunction, a unified approach with a 5mg dose is standard.
Dose for pulmonary hypertension
In the case of pulmonary hypertension, tadalafil is often available in 20mg tablet form. The standard dosage usually consists of 40mg, achieved by taking two 20mg tablets once daily.
Patients with renal or hepatic insufficiency may start on a lower dosage of either 10mg or 20mg as determined by their healthcare provider.
It is advised to swallow the tablets whole with a glass of water or juice, while grapefruit juice should be avoided due to possible interference with the drug’s metabolism.
For erectile dysfunction, taking one tablet at least 30 minutes before anticipated sexual activity is advisable.
For those using tadalafil in the context of prostate enlargement, it can be consumed any time of day, although establishing a consistent routine is recommended.
Note: Tadalafil tablets for pulmonary hypertension may be larger in size and could pose a challenge for some patients to swallow comfortably.
If you forget to take it
In instances where a dose is missed:
- For benign prostate enlargement: It’s best to take the omitted dose as soon as you remember, then continue with your regular dosing schedule.
- For pulmonary hypertension: If you recall within 8 hours, take it immediately; if not, skip the missed dose and resume your usual schedule without doubling up.
Avoid taking two doses simultaneously or compensating for a missed dose with an extra one later in the day.
For those who frequently overlook their doses, setting an alarm or asking a pharmacist for strategies to help remember can be beneficial.
If you take too much
Taking an excess of tadalafil may result in several side effects, which can include:
- Headache
- Dizziness
- Indigestion
- Nasal congestion
- Visual disturbances (like blurred vision)
Urgent advice: Contact a healthcare provider without delay if:
- You’ve ingested more than the prescribed amount of tadalafil.
