Can I take Sirdalud as a 17 year old?

At the outset, it should be noted that Sirdalud mentioned in the question is a prescription drug, so the legitimacy and need for its use in therapy should be determined by a doctor.

According to the summary of product characteristics, Sirdalud is contraindicated in patients below 18 years of age. This means that a 17-year-old should not take this medication.

However, your doctor may decide to use Sirdalud in a patient under 18 years of age if he or she considers that the benefits of treatment outweigh the potential risks. However, such a decision must be made individually in consultation with the attending physician. You can read more about it here:
