Lithium Side Effects: What You Should Watch For

Lithium is a common treatment for mood disorders like bipolar disorder, but like any medicine, it comes with side effects you should be aware of. Knowing these effects helps you spot issues early and work with your doctor to keep your treatment on track. Lithium works great for many people, but it isn’t without some risks.

Some side effects pop up pretty often. You might feel a bit shaky, thirsty, or notice you’re going to the bathroom more. These are usually mild and don’t require stopping lithium, but it’s good to mention them during your check-ups.

There’s also a chance of weight gain or some nausea, especially when you first start taking lithium. Your body can take a bit of time to adjust. Eating small, balanced meals and staying hydrated helps manage these early issues.

When Side Effects Become Serious

More serious side effects include confusion, extreme tiredness, or severe trembling. These can mean your lithium levels in the blood are too high, which needs quick attention to avoid harm. Regular blood tests can catch these warning signs early.

Kidney and thyroid problems may develop with long-term lithium use. Doctors usually keep an eye on kidney function and thyroid hormones with lab tests. If any trouble shows up, they can adjust your dose or suggest other steps.

Tips for Managing Lithium Side Effects

Keeping hydrated is important when on lithium—dehydration can increase side effects and cause lithium levels to spike. Avoid sudden changes in salt intake because that affects lithium balance too. Don’t stop lithium suddenly without talking to your doctor; doing so can cause mood shifts.

Overall, lithium can be a lifesaver, but it’s smart to stay informed about side effects. Open communication with your healthcare provider and regular lab work help you stay safe. If anything feels off, don’t wait—reach out to your doctor. This way, lithium can work well for you without causing unnecessary troubles.
