Mood stabilizers: What they do and how to stay safe

Mood swings that disrupt work, sleep, or relationships are treatable — mood stabilizers reduce mania, cut relapse risk, and help steady daily mood. These drugs are not one-size-fits-all: lithium, valproate (valproic acid/divalproex), carbamazepine, and lamotrigine each work differently and come with different monitoring needs. Some antipsychotics like quetiapine also act as mood stabilizers, especially when depression or psychosis is present.

How the main options compare

Lithium is the oldest and most studied mood stabilizer. It lowers suicide risk but needs regular blood tests to check levels, kidney, and thyroid function. Valproate is effective for mania but can harm the liver and cause birth defects, so avoid it in pregnancy and get liver tests and platelet counts. Carbamazepine helps some patients but can affect the blood and liver and interacts with many drugs. Lamotrigine is a good option for preventing depression episodes but must be started slowly to lower the risk of a severe rash.

Choosing a drug depends on your symptoms, sex, age, other health conditions, and other medicines you take. For example, valproate is usually a bad choice if you plan a pregnancy. Lithium may be risky for people with advanced kidney disease. Your prescriber will weigh benefits and risks and set up a monitoring plan.

Safety, side effects, and interactions

Common side effects vary: lithium can cause tremor, increased thirst, and weight gain; valproate may cause tiredness, nausea, and hair thinning; carbamazepine can cause dizziness and blood changes; lamotrigine can cause rash. Serious problems are rare but possible, so watch for fever, rash, severe stomach pain, unusual bleeding, confusion, or fainting and get medical help.

Drug interactions matter. NSAIDs, some diuretics, and ACE inhibitors can raise lithium levels. Carbamazepine speeds up liver enzymes and can reduce the effectiveness of hormonal birth control and other drugs. Always tell every prescriber and your pharmacist which meds and supplements you use.

Alcohol makes mood swings worse and can worsen side effects. Avoid mixing heavy drinking with mood stabilizers. If you need pain relief, ask a clinician which options are safest with your medication.

Buying prescriptions online? Only use reputable pharmacies that require a prescription, show clear contact details, and have verified reviews. We review many online pharmacies and publish buying tips to help you choose safely. Never buy controlled medicines from sites that skip prescriptions.

Finally, medication works best with routine: stick to dosing times, keep follow-up blood tests, and pair drugs with therapy and sleep, exercise, and a stable daily rhythm. If side effects start or mood symptoms change, contact your prescriber promptly for an adjustment.

Talk to your doctor about what to expect: how often you'll need blood tests, what symptoms to report, and how long to try a medicine before switching. Keep a mood diary for two months to track patterns. Bring a list of medicines to appointments. If you travel, carry a note about your prescription and lab schedule. Our guides cover monitoring schedules and safer online pharmacies.
