Amoxicilina/ácido clavulánico is an antibiotic that eliminates the bacteria that cause infections. It contains two different medicines called amoxicilina and ácido clavulánico.Amoxicilina belongs to a group of medicines known as “penicilinas” that sometimes may lose its effectiveness (become inactivated). The other component (ácido clavulánico) prevents this from happening..

Amoxicilina/ácido clavulánico is used in adults and children to treat the following infections:

• Acute ear, nose, and throat infections,
• Respiratory tract infections,
• Urinary tract infections,
• Skin and soft tissue infections, including dental infections,
• Bone and skin infections,
• Intra-abdominal infections,
• Genital infections in women.

Amoxicilina/ácido clavulánico is used in adults to prevent infections associated with major surgical procedures.

No use Amoxicilina/Ácido clavulánico Sandoz:

• if you are allergic to the active ingredients or to any of the other components of this medication (listed in section 6)
• if you have ever had a severe allergic reaction (hypersensitivity) to any other antibiotic. This could include skin rash or swelling of the face or neck,
• if you have ever had liver problems or jaundice (yellowing of the skin) when taking an antibiotic.

? Do not take Amoxicilina/Ácido clavulánico Sandoz if any of the above points apply to you. If you are unsure, consult your doctor, pharmacist, or nurse.

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting to use amoxicilina/ácido clavulánicoif:

• you have infectious mononucleosis,
• you are receiving treatment for liver or kidney problems,
• you do not urinate regularly.

If you are unsure whether any of the above symptoms affect you, inform your doctor, pharmacist, or nurse before receiving Amoxicilina/ácido clavulánico.

In some cases, your doctor may investigate the type of bacteria causing your infection. Depending on the results, you may be prescribed a different presentation of amoxicilina/ácido clavulánico or another medication.

Be aware of the following symptoms

Amoxicilina/ácido clavulánico may worsen existing conditions or cause serious side effects. These include allergic reactions, convulsions, and inflammation of the large intestine. Be aware of the following symptoms while you are receiving amoxicilina/ácido clavulánico, to reduce the risk of problems. See “Be aware of the following symptoms” in section 4.

Blood and urine tests

If you are having blood tests (such as red blood cell studies or liver function studies) or urine tests (to control glucose levels), inform your doctor or nurse that you are receiving amoxicilina/ácido clavulánico. This is because amoxicilina/ácido clavulánico may alter the results of these types of tests.

Use of Amoxicilina/Ácido clavulánico Sandoz with other medications

Inform your doctor or pharmacist if you are using, have used recently, or may need to use any other medication, including those obtained without a prescription and herbal medications.

If you are taking allopurinol (used for gout) with amoxicilina/ácido clavulánico, you may be more likely to have a skin allergic reaction.

Probenecid (used to treat gout), concomitant use of probenecid may reduce the excretion of amoxicilina and is not recommended.

If you are taking anticoagulants (such as warfarin) with amoxicilina/ácido clavulánico, more blood tests will be required.

Methotrexate (a medication used to treat cancer and severe psoriasis), penicillins may reduce the excretion of methotrexate and cause a potential increase in side effects.

Amoxicilina/ácido clavulánico may affect the way micophenolate mofetil (a medication used to prevent organ rejection in transplant patients) works.
