Moxatag is a penicillin antibiotic that fights bacteria.

Moxatag extended release tablets are used to treat tonsillitis and/or pharyngitis secondary to Streptococcus pyogenes (S. pyogenes) in adults and children 12 yrs and older.

Moxatag is an extended release tablet consisting of three parts, an immediate-release and two delayed-release components, each containing amoxicillin.

Do not use Moxatag if you are allergic to amoxicillin or to any other penicillin antibiotic, such as ampicillin (Omnipen, Principen), dicloxacillin (Dycill, Dynapen), oxacillin (Bactocill), penicillin (Beepen-VK, Ledercillin VK, Pen-V, Pen-Vee K, Pfizerpen, V-Cillin K, Veetids), and others.

Before using Moxatag, tell your doctor if you are allergic to cephalosporins such as Omnicef, Cefzil, Ceftin, Keflex, and others. Also tell your doctor if you have asthma, liver or kidney disease, a bleeding or blood clotting disorder, mononucleosis (also called "mono"), or any type of allergy.

Amoxicillin can make birth control pills less effective. Ask your doctor about using a non-hormone method of birth control (such as a condom, diaphragm, spermicide) to prevent pregnancy while taking this medicine. Take this medication for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Amoxicillin will not treat a viral infection such as the common cold or flu. Do not share this medication with another person, even if they have the same symptoms you have.

Antibiotic medicines can cause diarrhea. This may happen while you are taking Moxatag, or within a few months after you stop taking it. This may be a sign of a new infection. If you have diarrhea that is watery or bloody, stop taking Moxatag and call your doctor. Do not use anti-diarrhea medicine unless your doctor tells you to.

Take Moxatag exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.

The recommended dose of Moxatag is one 775 mg tabet taken once daily with food. The tablet should be taken within one hour of finishing a meal.

Take Moxatag around the same time every day for 10 days. Complete the full 10-day course of therapy for effective treatment. Do not skip any doses or stop taking Moxatag until you finish your prescribed treatment, unless you have a serious allergic reaction or your doctor tells you to stop.

Do not crush, chew, or break a Moxatag extended-release tablet. Swallow it whole. Breaking the tablet may cause too much of the amoxicillin to be released at one time.

While using this medicine, you may need frequent blood tests. Your kidney and liver function may also need to be checked.

Use this medicine for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics. Moxatag will not treat a viral infection such as the flu or a common cold.

Do not share this medicine with another person, even if they have the same symptoms you have.

This medicine can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using Moxatag.

Store at room temperature away from moisture, heat, and light.

You should not use Moxatag if you are allergic to any penicillin antibiotic, such as ampicillin, dicloxacillin, oxacillin, penicillin, or ticarcillin.

To make sure Moxatag is safe for you, tell your doctor if you have:

• kidney disease;

• mononucleosis (also called "mono");

• diarrhea caused by taking antibiotics; or

• food or drug allergies (especially to a cephalosporin antibiotic such as Omnicef, Cefzil, Ceftin, Keflex, and others).

It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.

Amoxicillin can make birth control pills less effective. Ask your doctor about using a non-hormonal birth control (condom, diaphragm, cervical cap, or contraceptive sponge) to prevent pregnancy.

It may not be safe to breastfeed while using this medicine. Ask your doctor about any risk.

Skip the missed dose and use your next dose at the regular time. Do not use two doses at one time.
