Dizziness: what’s really going on and what you can do

Feeling lightheaded or off-balance? That spinning, woozy, or faint feeling is a common reason people search for answers. Dizziness can come on suddenly or slowly. Sometimes it’s harmless and short-lived. Other times it signals a problem that needs medical attention. This page helps you spot likely causes, points out medicines that often play a role, and gives clear, practical steps you can take right away.

Common causes and medicines that can trigger dizziness

There are three broad reasons people feel dizzy: inner ear problems (vertigo), low blood pressure or poor circulation, and nervous system or medication effects. Here are specific, concrete triggers to watch for:

- Inner ear issues: benign positional vertigo is common and causes a spinning sensation when you change head position.

- Blood sugar or dehydration: low sugar or not enough fluids can make you lightheaded quickly.

- Low blood pressure or heart rhythm problems: these can cause faintness when standing up.

- Medicines: older antihistamines (the ones that make you sleepy), some antidepressants, blood pressure drugs, and some pain or migraine meds can cause dizziness. For example, newer antihistamines like fexofenadine tend to cause less drowsiness than older ones. Tricyclic antidepressants and some OTC combos may increase drowsiness and imbalance. If you’ve started, stopped, or changed the dose of a medication recently, that’s a common cause.

Quick steps to take right now

When dizziness hits, do this first: sit or lie down immediately. Don’t drive or operate machinery. Take slow, deep breaths and sip water. If you feel faint, put your head between your knees or lie flat with legs raised to improve blood flow to your brain.

A few practical checks: did you skip meals? Are you dehydrated? Did you stand up too fast? Check your pillbox — a recent change in prescription or a new OTC drug could explain it. If you have a blood pressure cuff, measure your BP sitting and standing; a big drop on standing suggests orthostatic hypotension (low standing blood pressure).

When to call a doctor or get emergency care: fainting, confusion, slurred speech, weakness on one side, chest pain, severe headache, or dizziness that lasts more than a day. Also contact your provider if dizziness began right after starting or changing a medicine.
