Lantus is the brand name for insulin glargine, a long‑acting insulin that smooths out blood‑sugar spikes throughout the day. If you’re living with type 1 or type 2 diabetes and need a steady baseline insulin, Lantus might be the right choice. This article breaks down the basics, so you can feel confident when you’re on it.
Unlike rapid‑acting insulins that kick in after a meal, Lantus forms a tiny depot under the skin and releases insulin slowly for up to 24 hours. That means you only need one injection a day, usually at the same time each night. It’s perfect for keeping fasting glucose stable, but you’ll still need a fast‑acting insulin for meals.
Doctors typically prescribe Lantus when a person’s basal insulin needs aren’t being met by shorter‑acting products. It’s also a go‑to for patients who have trouble remembering multiple daily shots. If you’re new to it, your provider will start you on a low dose and adjust based on your blood‑sugar logs.
Starting doses often range from 10 units to 20 units once daily, but the exact amount depends on body weight, diet, and current glucose levels. Always follow your doctor’s titration plan and check your blood sugar before making changes.
Most people tolerate Lantus well, but you might notice low‑blood‑sugar (hypoglycemia) if the dose is too high or if you skip a meal. Other side effects can include a mild rash at the injection site or a feeling of tingling. If any reaction seems severe, call your healthcare provider.
Store unopened pens in the fridge, but once you start using them, they can stay at room temperature for up to 30 days. Keep them away from direct heat and sunlight. Throw away any pen that looks cloudy or has particles inside.
Practical tips: set a daily alarm for your injection, rotate injection sites to avoid lipodystrophy, and keep a log of doses and glucose readings. These habits make it easier to spot patterns and keep your A1C in check.
If you travel, pack Lantus in a cooler bag and bring a backup pen in case the first one fails. Most airlines allow you to carry it in your hand luggage, but having a doctor’s note handy never hurts.
Finally, remember that Lantus is just one piece of diabetes management. Pair it with a balanced diet, regular exercise, and routine check‑ups. When you combine these steps, you’ll give yourself the best chance at stable sugars and fewer complications.
