5. Lightheadedness or Dizziness
You stand up from the sofa, and the room sways for a second. Not enough to fall, but enough to make you grab the armrest.
This occurs when blood pressure drops slightly upon standing—a common adjustment period effect. WebMD reports it’s often temporary and improves with simple habits.
Many only notice it early on or during dose changes.
4. Occasional Fatigue
Mornings start okay, but by afternoon you feel unusually drained, like your energy battery is low.
Fatigue can stem from your body adapting to lower pressure levels. It’s not constant for everyone, but when it hits, it feels unpredictable.
Research suggests it often fades as treatment continues.
3. Mild Headaches
A dull ache appears, especially when starting or increasing your dose. It feels like tension, not migraine-level pain.
Headaches relate to shifting blood flow in the head’s vessels. They typically resolve within days to weeks.
2. Awareness of Your Heartbeat (Palpitations)
Lying in bed, you suddenly feel your pulse thumping gently in your chest or neck. Not racing—just more noticeable.
This “palpitation” sensation is simply heightened awareness from improved blood flow. Daniel, 63, noticed it while watching TV and worried at first. It passed quickly.
It’s rarely serious but can feel startling.
1. Heaviness or Warmth in the Legs
After a short walk, your legs feel heavier or mildly warm, like post-exercise fatigue without the workout.
Increased blood flow to relaxed limb vessels causes this under-discussed effect. Once understood, most find it far less bothersome.
Here’s a quick comparison to help spot patterns:
Side Effect Possible Reason When It Often Appears Typical Duration
Ankle/Foot Swelling Fluid shift due to vessel relaxation Late afternoon/evening Improves overnight
Facial Flushing Rapid vessel widening Random, often brief Minutes
Dizziness Blood pressure adjustment When standing quickly Seconds to minutes
Fatigue Body adapting to lower pressure Midday or irregular Comes and goes
