Mood Changes: Causes, Medicines, and Practical Tips
Mood swings and low mood are common. Sometimes they come from life stress, sleep loss, or diet. Other times it’s a medical issue — thyroid problems, diabetes, neurological conditions, or side effects from medication. Even useful drugs like antidepressants or pain medicines can shift mood. If you notice sudden or severe mood changes, don't ignore them.
Quick checks
Track patterns for two weeks. Note sleep hours, appetite, alcohol use, stressful events, and any new medicines. Apps or a simple notebook work. If mood dips line up with starting a drug — for example moving onto Amitriptyline or switching antidepressants — mention this to your doctor. Some posts here, like our Lexapro guide and the Amitriptyline article, explain what to expect and which side effects might affect mood.
When medicines are the cause
Some medications change mood more often: steroids, some blood pressure drugs, certain pain killers, and even some antibiotics. Antidepressants can also cause early mood shifts before benefits appear. If a medication is likely, never stop it abruptly. Instead call your prescriber and ask about dose changes, timing, or alternatives. Our site reviews show how to buy and compare drugs safely if you need a different option.
Small changes often help fast. Prioritize sleep, move your body daily, cut back on booze, and eat regular meals. Try short walks, breathing breaks, or 10 minutes of sunlight every morning. Supplements like omega-3 (fish oil) can help some people — our fish oil article covers doses and brands. Therapy, peer support, or online programs are also effective and worth trying.
Watch for signs that need quick help: thoughts of harming yourself, confusion, extreme agitation, or very rapid mood swings. If someone talks about suicide or self-harm, call emergency services or a crisis line now. Your doctor can also fast-track assessments if medications or medical problems look responsible.

Practical checklist: Record mood three times daily and note exact start dates for any new medication. Cut caffeine and alcohol for two weeks while you watch for change. Ask your doctor for basic blood tests — thyroid, blood sugar, and vitamin D are common checks linked to mood. Finally, write three key questions to bring to your appointment: could this drug be the cause? Are there safer options? What short-term steps should I try?
