About Zithromax 500 (Azithromycin)

Azithromycin 500, the active ingredient in Zithromax, was discovered in 1980 and since then become one of the world’s most popular antibiotics. It is the most frequently prescribed antibiotic in America and is included on the World Health Organization list of essential medicines. It is available in online Canadian pharmacies under several generic names, Zithromax being the best-known among customers. When buying Zithromax from Canadian Pharmacy, you can be sure that you receive a top-quality product from a trusted supplier, manufactured under an official license;

Azithromycin belongs to the group of macrolide antibiotics and is used to treat a wide range of bacterial infections, including tonsillitis, otitis, pneumonia, chlamydia, gonorrhea, cervicitis, and others. The active ingredient in Zithromax works by attaching itself to phagocites (cells that ingest and destroy harmful bacteria, dead cells, and foreign particles), using them as transport to reach the areas where bacterial populations are most prevalent. Azithromycin then attaches itself to bacteria, preventing them from producing proteins, thus inhibiting their growth;

Zithromax 500 acts on a very wide variety of bacterial species, though its action is not particularly deep – some bacteria (especially those causing gonorrhea) have developed strands resistant to azithromycin. For this reason, Zithromax should sometimes be taken together with other antibiotics;

One of the advantages of Zithromax, which makes it so popular among customers of large online Canadian pharmacies, such as Canadian Pharmacy, is that it reaches its maximum concentration in the body just 2-3 hours after taking a pill and remains in the tissues for much longer that most other antibiotics. The half-life period of azithromycin equals almost three days, meaning that one larger dose can maintain its effect in the body for several days. On the other hand, the safety of Zithromax and the rarity of side effects mean that relatively large doses can be taken without the risk of adverse reactions;

Here at Canadian Pharmacy, we never cease to remind our customers: antibiotics can only be used to treat bacterial infections, and they are useless against viruses. Only take Zithromax if you have very good reasons to believe that your disease has a bacterial origin!

Buy Zithromax 500 at Canadian Online Pharmacy

When buying antibiotics online, one should be particularly careful with their choice of a pharmacy. Antibiotics are potent drugs, and low-quality or counterfeit product can lead to serious health damage. Unfortunately, a lot of pills sold online as antibiotics are counterfeit or – in the best-case scenario – contain much less of the active ingredient than stated on the package.

Low prices by themselves do not constitute a cause for doubt. For example, the purchasing team of Canadian Pharmacy continuously negotiates with suppliers in order to be able to offer its clients the best prices on the market. A large pharmacy has the necessary resources to organize regular sales and publish special deals.

When choosing a good online pharmacy in Canada to buy antibiotics like Zithromax 500, do not forget to check the payment and delivery options. Canadian Pharmacy accepts payment by all major credit cards and delivers both across Canada and overseas. Moreover, we make the safety of our clients’ personal details our priority and use the most advanced technologies to protect their data.

Finally, do not forget to study the sales in progress. While small pharmacies simply cannot afford to offer significant discounts, Canadian Pharmacy, being one of the market leaders and thus benefiting from economy of scale, continuously organizes sales that cover the whole product range, including the most expensive drugs. And our registered users can save even more by using the exclusive discount coupons that we regularly send them by email.

How To Take Zithromax

The correct dosage of Zithromax depends largely on specific bacterial infection. In general, efficacy is reported to be higher when Zithromax is taken together with food.

For those suffering from pneumonia, tonsillitis, otitis and other pulmonary and nasal infections, as well as for skin infections, the recommended dose is 500-600 mg on the first day and 250 mg daily afterwards for up to a week.

If you are taking Zithromax to treat STDs such as gonorrhea, chlamydia,  urethritis, or cervicitis, it is recommended to take just one dose of 1000 mg. If you have purchased Zithromax as oral suspension, dissolve the contents of the package in a glass of water and drink it all, adding some water to make sure you have taken the whole dose. Since azithromycin remains in your system for a whole week, this one dose will be enough to inhibit the growth of bacteria.

Side Effects & Overdose

Azithromycin is considered one of the safest antibiotics available from online Canadian pharmacies: only up to 8% of users experience any side effects at all, and less than 1% have to stop taking the drug due to the severity of side effects. The most common adverse reactions include headaches, nausea, and occasional stomach ache and nausea. Contrary to a popular misconception, most antibiotics (including Zithromax) do not reduce the effectiveness of birth control pills. It is quite safe to take Zithromax during pregnancy; however, caution should be exercised by breasfeeding women.

Canadian Pharmacy technicians would like to remind you that antibiotics inhibit the growth not only of harmful bacteria, but of many beneficial ones, too. Our intestinal tract is home to more “good” bacteria than there are cells in our body. These bacteria, collectively known as microbiome, play many complex functions in our body, and the reduction in their population caused by antibiotics can result in abdominal pain, diarrhea, cramps, or constipation. These symptoms are not side effects of Zithromax per se – they are consequences of a bacterial imbalance in the gut. Dysbacteriosis can result in serious issues such as colitis, so whenever you take antibiotics, make sure to include a lot of yogurt and other fermented dairy products in your diet or take probiotic supplements.

Very few cases of azithromycin have been reported; however, you should make sure to never take more than 600 mg when using it daily, or over one 1000mg dose in a week when administering just one dose. Seek urgent medical help if you develop any of the following: chest pain, severe dizziness, swelling or hives, jaundice, or irregular heart beat.

Zithromax 500 Alternatives

If you feel that you are not responding well to Zithromax, or if your illness does not fall into the list of those best treated with azithromycin, Canadian Pharmacy offers a large variety of alternatives.

Here are some of our most popular antibiotics that have gained enthusiastic reviews from our clients:

  • Amoxicillin – this famous and very affordable antibiotic is included on the WHO list of essential medicines and works great against ear infections, pneumonia (often in combination with Zithromax), bacterial sinusitis, some skin infections, and stomach infections caused by Helicobacter pylori. It can be used during pregnancy and breastfeeding but should not be taken by people who are allergic to penicillin.
  • Cipro – ciprofloxacin can act as an alternative to azithromycin in the treatment of respiratory and skin infections, and it is a better option than Zithromax when treating infections of bones and joints and urinal infections. Unfortunately, this wide-range antibiotic is often used to treat minor infections for which older, narrow-range antibiotics would work just as well. As a result, many bacteria are rapidly developing resistance to ciprofloxacin.
  • Keflex – the active ingredient, cefalexin, is the 5th most prescribed antibiotic in Canada. Keflex can be used to treat pneumonia, otitis, pharyngitis, urinary tract infections, and certain skin infections. It can be used by patients who are allergic to penicillin and by pregnant and breastfeeding women. Its side effects include nausea and vomiting, but in general Keflex is a very safe drug. Keep in mind that Keflex, just like any other antibiotic, cannot treat viral infections.


What STD is Zithromax used to treat?

Azithromycin is widely used to treat a whole range of sexually transmitted bacterial infections, including gonorrhea, chlamydia, urethritis, ureaplasma, and mycoplasma. For the treatment of gonorrhea, Zithromax is most efficient when used together with ceftriaxone.

Can you buy azithromycin without prescription?

Yes. Azithromycin was among the first antibiotics made available without a prescription, which reflects both its essential nature and its safety for most patients. However, when ordering Zithromax without prescription from an online Canadian pharmacy, make sure to acquaint yourself with its principle of action, correct mode of use, and contraindications.

How long does it take Zithromax to work?

If you are using Zithromax to treat a pulmonary, ear, or nose infections, such as tonsillitis or otitis, you should feel a relief after just one day. If you take azithromycin to treat an STD, simple infections like Chlamydia should be gone in about a week.

How long does it take Zithromax to leave your system?

The half-life period of Zithromax is 68 hours, and it will be fully out of your system in about a week. Such a long period is due to the fact that tissues actively absorb azithromycin.
