Zithromax (azithromycin) is an erythromycin related antibiotic. Some dermatologists prescribe Zithromax for treating acne vulgaris and rosacea, while the effects of this antibiotic in these conditions are still being studied. Still Zithromax does not compete with traditional acne treatments such as Tetracycline, Erythromycin, Minocycline, Doxycycline and Clindamycin Topical.

Zithromax is usually prescribed for treating a series of skin infections, respiratory tract infections such as pharyngitis, strep throat, tonsillitis, sinus infections and pneumonia; sexually transmitted diseases and genital ulcer disease with men. Zithromax is also used with children for treating pneumonia, strep throat and middle ear infections.

Zithromax is forbidden to be used for treating acne if you have a history of allergic reactions to azithromycin or similar medicines like erythromycin (E-Mycin, Ery-Tab, E.E.S.), clarithromycin (Biaxin), telithromycin (Ketek), or troleandomycin (Tao).

Make sure to inform your doctor if you have ever had liver or kidney disease, heart beat disorders or long QT syndrome before going through a course of Zithromax. In case you were diagnosed with any of these your doctor may consider adjusting your dosage or trying a different antibiotic for the treatment.

In very rare cases Zithromax can cause very serious reactions like angioedema and anaphylaxis, which can be very hazardous and even fatal. In case you experience face, lips, and neck swelling that makes it difficult to speak, swallow and breath call your doctor as soon as possible and seek medical assistance immediately.

Most doctors prescribe Zithromax for treating acne vulgaris in pulsed doses consisting of 3 days on and 7 days off for three times. Other form of dosage represents a 250 mg intake on Monday, Wednesday, and Friday during 10 weeks. Both methods are considered to be as effective as the 100mg a day course of Minocin — the medicine, which is regarded as the most effective antibiotic for treating acne vulgaris.
