[ 20 ] [ 31 ] [ 106 ] Sexual side effects in males may include erectile dysfunction , frequent erections, or prolonged erections . [ 20 ]
Because some adverse effects may only emerge during chronic use of methylphenidate, a constant watch for adverse effects is recommended.

The certainty of the evidence was stated as very low.
The researchers said that caffeine consumption of 400 mg daily “was shown to significantly impact the autonomic nervous system, raising the heart rate and blood pressure over time,” a news ...
ADHD medication tied to 19% lower death risk. An observational study conducted in Sweden, whose results appeared in JAMA in March 2024, further emphasized the positive impact of ADHD medication on ...
