Does Sudafed have a reaction on pupils?

Yes, Sudafed (pseudoephedrine) can cause pupil dilation, a condition known as mydriasis. This occurs because the medication stimulates the sympathetic nervous system, which can affect the muscles controlling pupil size. Additionally, some individuals may experience other side effects such as dry eyes or blurred vision. If you have concerns about this reaction, it's advisable to consult a healthcare professional.
