When I take enalapril I feel strange: my eyes feel heavy, I feel a bit “drunk”, my hands sweat and look pale. Is this normal?

Hello, Isabel: The symptoms you describe should not be ignored. Enalapril can cause, especially at the start of treatment or after a dose increase, an excessive drop in blood pressure. This can manifest as dizziness, a feeling of unsteadiness, blurred vision, weakness or a sensation of “floating”. However, it is also true that anxiety, low blood sugar or other medical problems can cause similar symptoms. The first thing I would recommend is to measure your blood pressure when those symptoms appear. That information can help determine whether there really is a drop in pressure related to the medication. Do not stop the treatment on your own, but it is important to consult the doctor who prescribed it to assess whether the dose is appropriate or whether it would be advisable to switch to another antihypertensive. If, in addition to that sensation, you develop chest pain, difficulty breathing, loss of consciousness or neurological symptoms, you should go to an emergency department. I hope this has been helpful. Kind regards.
