Can diltiazem capsules be opened?

In general, you should not open diltiazem capsules. These are often extended‑release formulations, and opening or crushing them can change how the medicine is released in your body, which can increase side effects or risk.

That said, some specific diltiazem products may allow sprinkling the contents on a small amount of soft food (like applesauce) if the label explicitly says so. If you see instructions like that on your package or patient information leaflet, follow them exactly. If there’s no such instruction, don’t open the capsule.

What to do now:
- Check the exact product name/strength on your bottle and read the instructions or patient leaflet.
- If you have trouble swallowing, talk to your pharmacist or prescriber about alternative forms (e.g., another tablet or liquid) or whether sprinkling is recommended for your exact product.
- If you’ve already opened or crushed a capsule and you’re unsure, contact your pharmacist or doctor for guidance.

If you can share the exact product name and strength, I can help confirm the proper guidance for that formulation.
