I recently started taking Diltiazem Hcl ER 180mg tablets to manage my high blood pressure and angina. The medication has been effective in reducing my symptoms, but I've also experienced some side effects that I want to share. I've been taking it once a day as prescribed, and it seems to be working well, but I've noticed some mild dizziness and fatigue. I wanted to know if anyone else has had similar experiences or if there are any tips for managing these side effects. Additionally, I'm curious about the long-term effects of this medication. Has anyone been on it for an extended period? I'd love to hear your thoughts and experiences.

I've heard that Diltiazem can also cause a significant drop in blood pressure, especially in the morning. If you're experiencing this, try taking it at night instead.

It's interesting how different people react to the same medication. I've had no issues with Diltiazem, but my friend had to switch because of severe dizziness.

I'm only on my first month of Diltiazem, I've had a few dizzy spells. I'm hoping it's just my body adjusting.

I tried Diltiazem once. It didn't agree with me at all. I've since switched to a different calcium channel blocker with much better results. It's all about finding what works for you.

Something to be aware of: Diltiazem can cause constipation. It's not a common side effect, but it's worth mentioning. Make sure you're staying hydrated and eating plenty of fiber.
