Zithromax is an antibiotic medication that is used to treat many different types of bacterial infections. It’s often used to treat certain skin infections, respiratory infections, ear infections, throat infections, sinus infections, and certain sexually transmitted diseases. It’s also commonly used for certain lung infections that are common in patients who have HIV. As an antibiotic, it works against the growth of bacteria to treat infections caused by them. It can’t treat infections caused by fungi or viruses. It can’t be used to fight a cold or the flu.

Like other antibiotics, it’s important to take this medication exactly as prescribed and not to stop taking it before all of the medication has been taken. When a patient stops taking an antibiotic early, it can lead to the bacteria becoming stronger and becoming an antibiotic-resistant infection. This medication is prescribed when the doctor suspects that the bacteria causing the disease is a type that is susceptible to it.

What Forms Does Zithromax Come In?

Zithromax can be administered as a tablet or as a liquid suspension. There are two types of liquid suspensions that it is available in. These are the extended-release suspension and the regular suspension. It’s common for this medication to be delivered as a powder that has to be mixed with water to create the suspension. If you mix it, be sure to use the amount of water called for. It’s also available as an injectable dose when administered in healthcare settings.

Precautions and Warnings of Zithromax

If you’re allergic to antibiotics, be sure your doctor knows about them. This is especially true if you’re allergic to clarithromycin (such as Biaxin), erythromycin, or telithromycin. If you have other allergies, you can find out the inactive ingredients of this medication by talking to the pharmacist. If you’re allergic to any of the ingredients, don’t take Zithromax.

Antacids shouldn’t be taken near the time when you take Zithromax. If you’ve taken an antacid, allow plenty of time to pass until you take your Zithromax. You can talk to your doctor about how long you specifically need to wait in between taking them. The exception is the extended-release liquid. If you’re taking that form, you can take it with antacids.

If you’ve ever had jaundice or another liver issue, tell your doctor before this medication is prescribed. You most likely will not be able to take this specific antibiotic. If you’ve had prolonged QT interval, a type of heart issue that can cause patients to faint or have an irregular heartbeat, tell the doctor. Your doctor should also know if you have a history of it in your family. If you have low magnesium or potassium or a blood infection, let the doctor know. It’s also important to tell them about your heart problems, myasthenia gravis, cystic fibrosis, or liver or kidney disease.

Pregnant women can take Zithromax if it’s needed as determined by your doctor. It isn’t suspected of causing problems in the unborn. It isn’t known whether it will pass into breast milk. Your doctor might not recommend this medication if you’re breastfeeding because it isn’t approved for use in anyone under six months old.
