Tadalafil (tadalafil) is a medicine used primarily for erectile dysfunction and benign hypertrophy of the prostate. In the long term, you may have the following side effects:
1. Cardiovascular effects
Arterial hypotension
Explanation: Tadalafil may cause a decrease in blood pressure, especially when combined with other medications that also affect blood pressure, such as nitrates. This is due to its relaxing effect on smooth vascular muscles, which can lead to a decrease in vascular resistance and a drop in systolic and diastolic blood pressure.
Prevention and management: patients should tell their doctor if they are taking nitrates or other blood pressure medications. In addition, blood pressure should be monitored regularly, especially in patients with a history of cardiovascular disease.
Congestive heart dysfunction
Explanation: in some cases, although less common, tadalafil may exacerbate congestive heart dysfunction. This is because generalized vascular relaxation can affect cardiac hemodynamics, especially in weak hearts.
Prevention and management: patients with congestive heart dysfunction should be carefully evaluated by a specialist doctor before starting treatment with tadalafil. The doctor should consider the severity of heart disease and the possibility of interactions with other medications the patient is taking.
2. Effects on the visual system
Changes in vision
Explanation: some patients may experience changes in vision, such as blurred vision or changes in color perception. This is because tadalafil can affect the function of the pigmentary Epithelium of the retina, which is important for visual adaptation and light perception.
Prevention and management: if a patient notices changes in vision while taking tadalafil, he or she should inform his or her doctor immediately. The doctor may evaluate the severity of the visual changes and determine whether it is necessary to stop treatment or perform additional tests, such as a complete ophthalmological examination.
3. Effects on other systems
Headache
Explanation: the incidence of headache is relatively common with the use of tadalafil. It may be due to medicine-induced cerebral vasodilation. There are different types of headaches that may occur, such as tensional pain or migraines.
Prevention and management: in many cases, headaches are mild and may disappear over time. However, if the headache is severe or persistent, the patient should consult his or her doctor. The doctor may recommend analgesics or evaluate the need to adjust the dose of tadalafil.
Abdominal pain and nausea
Explanation: Tadalafil may cause gastrointestinal discomfort, including abdominal pain and nausea. This is because the medicine can affect the tone and peristalsis of the gastrointestinal organs.
Prevention and management: taking tadalafil with food may in some cases mitigate these side effects. If symptoms are severe or persistent, the doctor should evaluate the situation and consider changing the medication or dose.
Prolonged and painful erections (priapism)
Explanation: although it is a very rare side effect, tadalafil may in some cases cause prolonged and painful erections, known as priapism. This is due to excessive relaxation of the smooth muscles of the penis, which prevents the blood circulation from being properly normalized.
Prevention and management: if a patient experiences an erection that lasts more than 4 hours, he should seek medical attention immediately. Treatment may include blood removal of the penis to relieve pressure and prevent permanent damage.
It is important that the use of tadalafil is supervised by a physician, and that patients report any abnormal side effects for proper evaluation and management.
