This medicine must be taken according to your healthcare provider's instructions. It is crucial to follow their advice regarding dosage, especially if you have a tadalafil 5mg prescription. Always inform your healthcare provider about all the medications you are currently taking to avoid potential interactions.
When you receive a private prescription for tadalafil, thoroughly review the provided information. Dosage instructions may vary based on individual health factors, including other medical conditions or medications.
Dosage and Strength
Tadalafil is formulated in various strengths: 2.5mg, 5mg, 10mg, and 20mg tablets, each serving different purposes depending on the condition being treated.
Dose for Erectile Dysfunction
For erectile dysfunction, the standard initial dose is generally 10mg, administered before sexual activity. Importantly, do not exceed one tablet in a 24-hour period.
Your physician may adjust your dosage according to the medication's effectiveness and your frequency of use.
Remember that the effects of tadalafil can exceed 24 hours, so daily consumption of the 10mg or 20mg doses is typically not recommended, as this can increase the risk of side effects.
For optimal results, sexual arousal is necessary for the tablet's effectiveness.
Dose for Benign Prostate Enlargement
For benign prostatic hyperplasia (BPH), tadalafil is available in 2.5mg or 5mg tablets, with the 5mg dose being the standard for daily use.
If you have both BPH and erectile dysfunction, a combined dosage of 5mg is often recommended.
Dose for Pulmonary Hypertension
In treating pulmonary hypertension, tadalafil is typically prescribed in 20mg doses.
The standard dosage is often 40mg, taken as two 20mg tablets once daily.
If you have existing kidney or liver issues, your healthcare provider may consider lowering the starting dose to 10mg or 20mg to ensure safety.
Always ingest your tablets whole, alongside water or juice (but avoid grapefruit juice, as it may interfere with the medication).
For erectile dysfunction, it is advisable to take one tablet at least 30 minutes prior to planned sexual activity.
When treating prostate enlargement, you can take tadalafil either in the morning or evening, but maintaining a consistent daily routine is advisable for optimum results.
Note that tadalafil tablets designed for pulmonary hypertension may be larger and could pose difficulties in swallowing for some individuals.
If You Forget to Take It
If you missed a dose:
- For benign prostatic hyperplasia – take the dose as soon as you remember, then continue with your regular schedule.
- For pulmonary hypertension – if you remember within 8 hours, take the dose; otherwise, skip it and proceed with your usual regimen.
Never double your dose to compensate for a missed one. If you have trouble remembering to take your medication, setting an alarm or consulting a pharmacist for memory aids might be helpful.
If You Take Too Much
Taking more tadalafil than prescribed may result in side effects, including:
- headache
- dizziness
- indigestion
- stuffy nose
- visual disturbances (such as blurred vision)
