Tadalafil 20 mg dose: variations by condition and Doctor.

tadalafil (20 mg) should be taken according to the following general guidelines, but it is very important that it be done under medical supervision:

1. Mode of ingestion

-it should be taken with a glass of water, whether with or without food. However, a large amount of fat in the food can delay the absorption and start of action of the drug.

2. Frequency

-it shouldn't be taken more than once a day.

3. Special precautions

-it should not be combined with nitrates (used, for example, for angina pectoris), as the combination can cause a drastic drop in blood pressure, which can be dangerous.

-before taking tadalafil, you should tell your doctor if you have kidney or liver problems, as this may require a dose adjustment.

-you should also tell your doctor if you are taking other medications, as there may be interactions.

Remember that the use of tadalafil should be authorized by a doctor, who will assess whether it is suitable for you based on your general health status and specific medical needs.
