The Side Effects Most People Experience

Let’s start with the things you’re more likely to notice in terms of levofloxacin side effects. Your stomach might not be too happy with this medication at first. You could feel a bit queasy, have some diarrhea, or find yourself dealing with constipation instead. Your appetite might dip, or your stomach might feel a little off. These symptoms are usually pretty mild and often improve after the first few days as your body adjusts to the medicine.

Headaches happen to quite a few people taking levofloxacin. You might also feel dizzy, especially when you stand up too quickly. If you’ve ever gotten up too fast and felt lightheaded, it might be more noticeable while you’re taking this medication. Take your time getting out of bed in the morning or standing up from your couch. Some people also find it harder to fall asleep at night or feel more restless than usual. If sleep becomes a problem, ask your doctor if you can take your dose earlier in the day.

The Serious Stuff You Need to Know About

Now for the more concerning side effects. These are things you really need to watch for. Levofloxacin can cause problems with your tendons. You might suddenly feel pain in your ankle, shoulder, hand, or other joints. The area might swell up, bruise, or you might find you can’t move it properly. This can happen even after you’ve stopped taking the medication. If this happens, stop taking levofloxacin right away and call your doctor. Don’t push through the pain or keep using that joint, because the tendon could actually tear.

This medication can also mess with your nervous system in ways that need immediate attention. Some people feel confused or shaky. Others have experienced depression or even scary thoughts about hurting themselves. Seizures can happen, though they’re rare. There’s also something called nerve damage that can develop. You might feel pain, burning, tingling, numbness, or weakness in your arms, hands, legs, or feet. If you notice any weird sensations like this, call your doctor right away. The concerning thing about nerve damage is that it can become permanent if you keep taking the medication.

How It Might Affect Your Heart and Blood Sugar

Levofloxacin can change how your heart beats. Your heart might feel like it’s racing or pounding, or you might feel suddenly dizzy or like you’re going to faint. This is more likely if you already have heart issues or take other medications that affect your heart rhythm, but it’s worth knowing about regardless.

If you have diabetes, pay extra attention to your blood sugar while taking this medication. Actually, even if you don’t have diabetes, your blood sugar can still go haywire. If your blood sugar drops too low, you might suddenly feel sweaty, shaky, or hungry, and you might notice tingling in your hands or feet. If it goes too high, you’ll probably feel really thirsty, need to urinate more often, have a dry mouth, or notice your breath smells fruity. Either way, let your doctor know.

Allergic Reactions and Sun Sensitivity

Sometimes people are allergic to levofloxacin. You might get a rash or start itching. If you develop hives, have trouble breathing or swallowing, or notice swelling in your face, lips, tongue, or throat, that’s an emergency. Call for help right away. The same goes if you develop a severe skin reaction with fever, sore throat, burning eyes, skin pain, and a rash that spreads and causes blistering.

Here’s something that surprises a lot of people: this medication makes you burn in the sun much more easily. You’re at greater risk of getting a bad sunburn even on a cloudy day or after just a short time outside. While you’re taking levofloxacin and for a few days after, really limit your sun exposure. Wear long sleeves and pants whenever possible, use a strong sunscreen, and skip the tanning bed entirely.

Other Things You Might Notice

This medication could affect your liver. Watch for yellowing of your skin or the whites of your eyes, dark urine that looks like tea, pale or clay-colored stools, severe stomach pain, or feeling unusually exhausted. These are signs your liver might be struggling.

Some people notice weird changes in how things taste. Food might taste off, or you might have a bad taste in your mouth that won’t go away. Less commonly, you might hear ringing in your ears or notice your vision getting blurry. Your muscles might ache or feel weak, and some people experience joint pain throughout their bodies.

Watch out for severe diarrhea, especially if it’s watery or contains blood. This could mean you’ve developed a more serious intestinal problem. Don’t just grab some anti-diarrhea medicine from the pharmacy without talking to your doctor first, as it could make things worse.

Making This Easier on Yourself

Taking your medication with food or a glass of milk might help your stomach feel better, though you can also take it on an empty stomach if that works better for you. Drink plenty of water throughout the day. This helps your kidneys and keeps you hydrated.

Try to take your dose at the same time every day. If you forget a dose, take it when you remember, unless your next dose is coming up soon. Never double up on doses.

Here’s something important: don’t take levofloxacin at the same time as antacids, iron or zinc supplements, or dairy products. They can interfere with how well the antibiotic works. Space them out by at least two hours.

When You Should Reach Out for Help

Call your doctor about any side effect that worries you. Don’t stop taking the medication on your own, though, because stopping antibiotics early can let your infection come roaring back. That said, if you experience tendon pain, nerve problems, changes in heart rhythm, signs of an allergic reaction, or liver problems, contact your doctor immediately or seek emergency help.

Reading through all these potential problems might make you nervous about taking your medication. Remember, many people take levofloxacin and feel fine, or experience only minor symptoms such as a mild headache or stomach upset. The point of knowing all this isn’t to frighten you; it’s to help you recognize when something needs attention. Your doctor prescribed this medication because they believe the benefits outweigh the risks for your particular situation. If you have questions or concerns while taking it, don’t hesitate to call your doctor or pharmacist. They’re there to help you get through your infection safely.
