Azithromycin
About Azithromycin
Azithromycin is an oral antibiotic medication prescribed to treat a wide variety of bacterial infections. It works by stopping the growth of bacteria, allowing your body's immune system to naturally clear the infection. Doctors frequently prescribe it for infections of the lungs, throat, sinuses, and skin.
To ensure the medicine works effectively, you must take Azithromycin consistently at the same time each day as directed by your doctor. You can take this medication with or without food, though taking it with a meal can help prevent stomach upset. Eating a balanced diet and resting well can also help your body recover faster from the infection.
While taking this medication, you may experience mild side effects like nausea, vomiting, or diarrhoea. However, if you develop severe watery diarrhoea, a very fast heartbeat, or yellowing of your skin or eyes, you should contact your doctor right away.
Before you begin taking Azithromycin, talk to your doctor if you have a history of liver disease, kidney problems, or heart rhythm disorders. Do not take this medication if you are allergic to it or similar antibiotics, or if you have previously suffered liver damage from using this type of medicine.
Azithromycin is also commonly prescribed for certain bacterial infections in children. The dose is usually calculated according to the child's body weight and must be determined by a doctor or pharmacist.
This medication can interact with other substances; for example, taking it with antacids can lower its absorption, making it less effective. If you are pregnant, breastfeeding, or managing health conditions as an elderly individual, consult your doctor or pharmacist before starting treatment.
