Tadalafil is a medicine that should be purchased with a prescription.

1. Risks of over-the-counter purchase

-buying tadalafil without a prescription from unauthorized sources (for example, on some unregulated websites or from illegal sources) may expose the user to counterfeit, low-quality or contaminated drugs. These products may not have the expected effectiveness and, worse still, can cause serious adverse health effects, including heart damage, changes in blood pressure, and other problems.

2. Legal purchasing process

-if you have a medical condition for which a doctor has determined that tadalafil is appropriate, the prescription should be obtained. It can then be purchased from an authorized pharmacy, either from a local physical pharmacy or, in some cases, from an online pharmacy that operates legally and accepts electronic or physical medical prescriptions.

-in addition, the doctor should evaluate the general health of the patient, possible interactions with other medications that the patient may be taking, and any risk factors before prescribing tadalafil.
