What is Azithromycin?

Azithromycin treats an extensive range of bacterial infections by stopping their growth. It belongs to class Macrolide comprising a broad antibacterial spectrum similar but not identical to Penicillin. As a macrolide antibiotic, it inhibits the protein synthesis of bacteria by targeting its ribosome.

Its work works against some penicillin-resistant bacteria. Doctors sometimes prescribe Azithromycin as an alternative treatment for penicillin-allergic patients.

What does Azithromycin treat?

Azithromycin aids in treating bacterial infections such as bronchitis, pneumonia, ear infections, lung infections, sinuses, sexually transmitted diseases (STDs) and infections of skin, throat and reproductive organs.

It also helps prevent disseminated Mycobacterium Avium complex (MAC) infection (rare lung infection) that affects people with HIV.

What are the drug interactions of Azithromycin?

When taken with nelfinavir (HIV drug), Azithromycin can increase the risk of developing liver diseases and hearing problems. It can also increase the potential of blood thinners such as warfarin. Other drugs that interact with Azithromycin include digoxin (heart medication), colchicine (gout medicine), phenytoin (seizure medicine), and magnesium or aluminum-based antacids.

We have not listed all the drugs; make sure to provide your medical history and ongoing medication details with your doctor before prescribing the drug.

What are the side effects of Azithromycin?

Some common side effects of Azithromycin include diarrhea, nausea, vomiting, stomach pain and headache. However, you must seek emergency help if the symptoms persist or worsen.

Some severe side effects that require immediate emergency help include severe stomach pain, water or bloody diarrhea, heart palpitations, sudden dizziness that felt passing out, fast-beating or pounding heartbeats, and shortness of breath. Some side effects may occur in your livers, including symptoms like loss of appetite, dark urine, jaundice, clay-colored stools, itching, upper stomach pain, nausea, and tiredness.

Azithromycin may cause allergic reactions to some people, including swelling on the face or throat, hives, breathing difficulties, fever, swollen glands, muscle pain, flu-like symptoms, severe weakness, rash, unusual bruising, and yellowing of skin or eyes. These reactions may occur while taking Azithromycin or may occur weeks after you complete the course. However, if you notice any allergy symptoms, you need emergency help as soon as possible.

No Azithromycin is only available by prescription. However, asymptomatic chlamydia patients above 16 years can buy Azithromycin over the counter under the brand name Clamelle. The drug comes with strength of 500 mg. The person needs to test positive in the lamellae chlamydia testing kit and show the results at the pharmacy to purchase the drug.
One can take Azithromycin during pregnancy, breastfeeding or trying to get pregnant. Studies on animals consuming high doses of Azithromycin shows no increased risk of congenital disabilities or miscarriage. However, there are no significant studies on its effect on pregnant humans. So, your doctor may prescribe you Azithromycin only if they rule out all other alternatives.Azithromycin can transfer into breast milk and remain for 48 hours after the last dose. Sometimes it may cause diarrhea, rash or vomiting in some infants. You must call your doctor if you need any side effects.
Doctors usually prescribe only a single dose of Azithromycin for treating gonorrhea. Your symptoms start you clear up within 1-2 days, but it will take around two weeks for all symptoms to subside. However, we recommend you get tested again after one week of starting your treatment. CDC recommends that doctors treat gonorrhea with dual therapy, including two antibiotics- Cephalosporin and Azithromycin. Each of these carries a unique mechanism of action against the N. Gonorrhea bacteria. Actually, cephalosporin helps kill the bacteria, while Azithromycin helps slow down the bacteria from becoming resistant to the cephalosporin. Another reason behind the dual therapy is that people infected with gonorrhea are more likely to have chlamydia. Since Azithromycin is a powerful, effective treatment for chlamydia, dual therapy works great in both ways.
Azithromycin tablets in 500mg help treat acute bacterial sinusitis, skin & soft tissue infections, mild to moderately severe pneumonia, pharyngitis, tonsillitis, acute bacterial otitis media, acute exacerbation of chronic bronchitis, and uncomplicated chlamydia trachomatis urethritis and cervicitis.
Yes, there are various online pharmacies in the UK selling Azithromycin. However, you need a valid prescription from a certified medical professional.
A brick-and-mortar pharmacy is less likely to sell medicines below the retail price as it requires money to run and manage a shop. Meanwhile, online pharmacies do not have to do that, and they also buy directly from the manufacturer, cutting the whole middlemen scenarios. As a result, you can buy Azithromycin at a cheap price online.
