Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thing to know about pairing light therapy with moexipril (Univasc). Some blood pressure medicines, including certain ACE inhibitors like this one, can make your skin a little more sensitive to bright light. Since light therapy uses intense artificial light, the concern is that you might be more prone to a skin reaction, think redness, irritation, or a sunburn-like feeling, mostly on areas of exposed skin.

I want to be honest about how strong this concern is: it's theoretical, based on how these drugs behave rather than lots of real-world reports. Most people use a light box aimed at the face and eyes for short sessions, so a major reaction isn't likely. Still, if you notice unusual skin sensitivity, mention it to your pharmacist or doctor before changing anything.

About Light Therapy

What is Light Therapy?

  • Seasonal affective disorder (SAD)
  • Non-seasonal depression
  • Sleep and circadian rhythm problems
  • Jet lag and shift-work sleep issues
  • Certain skin conditions

Light therapy uses controlled exposure to bright artificial light and is best supported for seasonal affective disorder, where it is a recognized treatment option. It is generally safe for most people when used as directed, but you should talk to a doctor or pharmacist first, especially if you have eye conditions, bipolar disorder, or take medicines that increase light sensitivity.

About Moexipril

What Is Moexipril Used For?

Brand name: Univasc

Moexipril Hydrochloride tablets are used to treat high blood pressure (hypertension). They can be used on their own or combined with thiazide diuretics (water pills) when blood pressure is not controlled by moexipril alone.

It's worth knowing that ACE inhibitors, including moexipril, tend to lower blood pressure less effectively in Black patients than in non-Black patients, and Black patients also have a higher risk of a serious swelling reaction called angioedema with ACE inhibitors.
