The Z-Pak is an oral antibiotic that is sometimes used to treat conditions such as bronchitis, sinus infections, ear infections, certain types of pneumonia and strep throat, depending on the judgement of the prescribing provider. Farmington Drugs & Medical Supplies provides  patients who need Z-Pack prescriptions at our home pharmacy or via free local deliveries for prescription refills.

More information

  • Z-Pak versus Zithromax

    What is a Z-Pak (Z-Pack)? A Z-Pak is a convenient package that contains six tablets of the medication Zithromax. Each Zithromax pill in the Z-Pak is a 250-milligram dose. The reason that a Z-Pak is packaged this way is that some regimens that utilize Zithromax for the treatment of various conditions consist of two 250mg tablets on the first day followed by one tablet daily for four days. The Z-Pack is packaged in a convenient blister pack that makes it easy to remember how many azithromycin pills to take and which day of treatment one is on. And so, in comparing a Z-Pak versus Zithromax, the Z-Pak actually contains six tablets of the 250mg form of Zithromax. However, Zithromax is available in dosages different than what is found in the Z-Pak.

  • Zithromax – Side Effects

    Side effects of a Z-Pack (Zithromax) include an upset stomach, nausea, dizziness, rash, and vomiting. More severe side effects of Zithromax include cardiac arrhythmias and allergic reactions. People who are allergic to macrolides or ketolide drugs should not take Zithromax. Also, a Z-Pak is not recommended for people with a history of certain types of liver disease. Zithromax can also cause drug interactions with warfarin and nelfinavir. Questions regarding the side effects of taking a Z-Pak should be discussed with one’s pharmacist and medical provider.

  • Cost Information

    The Z-Pack and Zithromax are prescription medications that are not available over-the-counter (OTC) in the United States. Fortunately, Zithromax is a Z-Pak is relatively affordable at under $2 per pill at many pharmacies. Z-Pak and Zithromax coupons may also be available through Pfizer to help reduce the cost. Getting a Z-Pack (Zithromax) without a doctor can be difficult but Push Health can connect people in need of a Z-Pak prescription with a licensed medical provider who can prescribe the medication if it is appropriate to do so. Farmington Drugs & Medical Supplies takes pride in offering the most cost efficient services and prescriptions to our patients.

  • Dosage

    Zithromax 250 mg pills – the kind found in both bottles and Z-Pak blister cards – are pink modified capsular shaped tablets that actually contain azithromycin dihydrate equivalent to 250mg. These Zithromax tablets are typically engraved with “306” on one side and “Pfizer” on the other side of the medication. Zithromax also comes in the form of 500mg tablets that appear similar to the 250mg Zithromax pills except that they are engraved with “ZTM500” on one side and “Pfizer” on the other side instead. Zithromax is also available as an oral suspension in 100mg/5mL and 200mg/5mL suspensions.

  • Azithromycin vs. Amoxicillin – Antibiotic Choices

    When comparing Zithromax versus amoxicillin as antibiotic choices, it is not always clear how they are different and it can be helpful to know distinguishing factors. Zithromax, as found in the Z-Pak, belongs to a class of antibiotics known as macrolide antibiotics. Amoxicillin, on the other hand, is a derivative of penicillin. Some people are allergic to macrolide antibiotics while others are allergic to penicillins. Also, Zithromax is useful in treating different types of infections in some cases. As a result, when deciding on a Z-Pak versus amoxicillin in treating an infection, a number of factors are important in the decision, including the likelihood of antibiotic resistance, the patient’s medical history and allergy profile, and cost considerations.
