If you or someone you love has bipolar disorder, getting the Lamictal dose right can feel like a puzzle. The good news? It’s not as hard as it sounds once you know the basic steps. Below you’ll find the most common starting point, how to move up safely, and what to watch out for.
The usual adult starter is 25 mg once a day for the first two weeks. That tiny amount may seem pointless, but it helps your body get used to lamotrigine and cuts the risk of a rash, which is the most serious side effect. If you’re already on another mood stabiliser, your doctor might keep you at 25 mg for four weeks before any increase.
After the initial two‑week period, the dose typically rises to 50 mg daily for the next two weeks. From there you add another 50 mg every two weeks until you hit the target range of 200 mg‑300 mg per day. Most people end up staying around 200 mg daily for maintenance, but some need up to 400 mg if symptoms aren’t controlled.
Always follow the exact two‑week schedule—jumping ahead can trigger skin reactions. If you miss a day, take the missed dose as soon as you remember, unless it’s already close to the next dose. In that case, just skip the missed one; don’t double up.
Kids and teens start at a lower weight‑based dose, usually 0.1‑0.2 mg/kg per day, and then follow a similar slow‑rise plan. Seniors may stay at the lower end of the adult range because they process the drug more slowly.
People with liver or kidney problems often need a modest reduction—typically 25‑30% less than the standard dose. Your doctor will check blood work if you have these issues.
When you reach your maintenance dose, keep taking it at the same time each day. Consistency helps keep mood swings at bay and makes it easier to spot any side effects.
Common side effects include dizziness, headache, and mild nausea—usually fade after a few weeks. A rash anywhere on the body, especially if it’s itchy or spreads fast, means you should stop the medicine and call a doctor right away.
If you’re pregnant or planning to become pregnant, talk to your doctor. Lamictal is generally safer than many alternatives, but dosage may need tweaking to keep both mother and baby safe.
In summary, start low (25 mg), titrate up every two weeks by 50 mg, aim for 200‑300 mg daily for most adults, and adjust for age, weight, or organ function. Stick to the schedule, watch for rash, and keep your doctor in the loop. With the right dose, Lamictal can smooth out the highs and lows of bipolar disorder without the roller‑coaster feeling.
