Uses
Zithromax is useful for the treatment of various types of infections which are caused by bacteria, including sexually-transmitted diseases, infection of the ear, the skin, and the respiratory tract, bronchitis, tonsillitis, and pneumonia.

How to take Zithromax
Zithromax is an oral ingestion drug, which comes in liquid, capsule, and tablet form. It is normally taken once a day, within two to five days. Take the medication upon careful observation of the doctor's prescription. The capsule or tablet should be taken on an empty stomach, about an hour before or two hours after a meal, with a tall glass of water. Shake the liquid well before mixing the single dose evenly in two ounces of water and drinking all of it immediately.

Side effects
If symptoms of an allergic reaction or liver damage (severe fatigue, yellowing of the eyes or the skin, bruising or bleeding, nausea, and abdominal pain) are experienced, the user is advised to discontinue use and seek immediate medical help. If symptoms such as nausea, an increased sensitivity to sunlight, vomiting, rashes, diarrhea, vaginal yeast infection, abdominal pain, headaches, unusual dizziness, and fatigue are experienced, continue medication and consult with a doctor.

Drug precautions
Antibiotic medications may cause diarrhea, which can be a sign for new infection. If diarrhea has blood in it or is watery, seek medical help; do not take any medication for stopping the diarrhea unless otherwise instructed by a doctor. People under the treatment of Zithromax should also avoid being exposed to natural or artificial UV rays, as the drug can increase the sensitivity of the skin to such rays; apply sunscreen or wear protective clothing when going out under the sun.
