If you’ve been prescribed roxithromycin, you’re probably dealing with a bacterial infection. It belongs to the macrolide family, the same group as erythromycin and azithromycin. Doctors often choose it for respiratory infections, skin infections, and some ear or sinus problems. The drug works by stopping bacteria from making proteins they need to grow, so the infection can’t spread.
Roxithromycin is taken by mouth, usually in tablet or capsule form. It’s absorbed well, which means you get reliable blood levels without needing injections. Because it stays in the body longer than some other antibiotics, you often only need to take it once or twice a day.
Take roxithromycin exactly as your doctor tells you. Most adults start with 150 mg twice a day, but the dose can change based on the infection’s severity and your kidney or liver health. Swallow the tablets whole with a glass of water; don’t crush or chew them.
It’s best to take the dose at the same times each day—like breakfast and dinner—to keep a steady level in your bloodstream. If you forget a dose, take it as soon as you remember, unless it’s almost time for the next one. In that case, skip the missed dose and continue as normal. Never double up to make up for a missed pill.
Most people tolerate roxithromycin well, but a few side effects are common. Stomach upset, nausea, and mild diarrhea happen in some patients. If you notice these symptoms, taking the drug with food can help, even though it’s not required.
More serious reactions are rare but need attention right away. Look out for rash, itching, swelling, or trouble breathing—these could be signs of an allergic reaction. A rapid heartbeat, severe stomach pain, or yellowing of the skin or eyes might indicate liver trouble. If any of these appear, stop the medication and seek medical help.
Because roxithromycin can affect the heart’s rhythm, especially in people with existing heart issues, tell your doctor about any history of arrhythmias or if you’re on other drugs that lengthen the QT interval.
Interactions matter, too. Antacids containing aluminum or magnesium can lower how much roxithromycin your body absorbs, so space them at least two hours apart. Blood thinners like warfarin may need closer monitoring, as roxithromycin can increase their effect.
When you finish the prescribed course, don’t stop early even if you feel better. Cutting the treatment short can let the bacteria survive and become resistant, making future infections harder to treat.
In summary, roxithromycin is a handy antibiotic for many common infections. Follow the dosing schedule, watch for side effects, and keep an eye on possible drug interactions. If you’re unsure about anything—dosage, timing, or how you feel—talk to your pharmacist or doctor. They can clear up concerns and help you finish the treatment safely.
