Micardis Plus side effects: What you need to know

When you’re taking Micardis Plus, a combination blood pressure medication containing telmisartan and hydrochlorothiazide. Also known as a dual-action antihypertensive, it’s designed to lower blood pressure by relaxing blood vessels and helping your body get rid of extra fluid. Many people take it without issues, but like any medicine, it can cause side effects—and some of them are easy to miss if you don’t know what to look for.

The two parts of Micardis Plus work differently but together. Telmisartan, an ARB (angiotensin II receptor blocker). Also known as a blood vessel relaxer, it stops a hormone from narrowing your arteries, which lowers pressure. Hydrochlorothiazide, a thiazide diuretic. Also known as a water pill, tells your kidneys to flush out more salt and water. That’s why some people feel the need to pee more often. But this combo can also drop your potassium too low, cause dizziness when you stand up, or make you feel unusually tired. These aren’t rare—they happen often enough that doctors check your blood levels every few months.

If you’re on Micardis Plus, watch for signs like muscle cramps, irregular heartbeat, extreme dry mouth, or confusion. These could point to low potassium or dehydration. People over 65 or those with kidney problems are more at risk. You might not feel anything at first, but over time, unmanaged side effects can lead to bigger problems. That’s why tracking how you feel matters more than just taking the pill. Keep a simple log: note dizziness, fatigue, or changes in urination. Bring it to your next appointment. It’s not about fear—it’s about control.

Some side effects are mild and fade after a few weeks. Others need action. If you get swelling in your face, lips, or throat, stop taking it and get help right away—that’s a rare but serious allergic reaction. Same if you stop urinating or notice yellowing skin or eyes. These aren’t common, but they’re serious enough that you need to know them. The goal isn’t to scare you, but to make sure you’re not ignoring signals your body is sending.

What you’ll find in the posts below are real, practical guides from people who’ve been there. You’ll see how others managed dizziness, what foods help balance potassium, how to tell if your blood pressure is dropping too far, and when to call your doctor instead of waiting. No fluff. No jargon. Just what works—and what doesn’t.
