Tadalafil is a prescription medicine used to treat conditions such as erectile dysfunction and benign prostatic hyperplasia. The 2.5 mg dose is usually prescribed to be taken once daily at the same time each day and works by maintaining a steady level of the medicine in the body rather than giving an immediate effect before sexual activity. Taking tadalafil 2.5 mg only before sex may not be effective. The dose, timing, and suitability of tadalafil vary from person to person and should be determined by a doctor after a proper medical evaluation. Patients should not start, stop, or change this medicine without consulting a healthcare professional.

Frothy urine does not always indicate a kidney stone, as it can also occur due to dehydration or a urinary infection. You should not take two Tadalafil 2.5 mg tablets on your own without medical advice. It is better to consult a doctor, get proper urine tests and use medicines only after the cause is confirmed.

Taking two Tadalafil 2.5 mg tablets will not make it work faster, as the start time stays almost the same. A higher dose may increase the effect, but it also raises the risk of side effects. Dose changes should not be done on your own. It is better to consult your doctor before increasing the amount.

Tadalafil 2.5 mg Tablet usually starts working within 30-60 minutes after taking it, though this can vary from person to person. Its effect may be influenced by food, alcohol, or other medications. For best results and safety, follow your doctor's instructions on timing and dosage.

Tadalafil 2.5 mg is usually given as a daily dose, but the correct dose and duration depend on your age, the condition being treated, the severity of your symptoms, your kidney and liver health, any other medicines you are taking, and your doctor's overall treatment plan. So, you should not start or change this medicine without medical guidance.

The directions you mentioned seem unclear, as Tadalafil 5 mg is usually taken only once daily, with or without food. Taking “2 after meals and one at dinner” is not a typical dose for this medicine. The exact dosage depends on your specific medical condition and overall health, so it’s vital to confirm directly with your doctor before taking it. Do not change or start the dose on your own without medical advice.
