Polymox Suspension : Uses, Side Effects, Interactions & More

Why is this medication prescribed?

Polymox Suspension (Amoxicillin) is used to treat certain infections caused by bacteria, such as pneumonia; bronchitis (infection of the airways leading to the lungs); and ear, nose, throat, urinary tract, and skin infections. It is also used in combination with other medications to kill H. pylori, a bacteria that causes ulcers. Polymox Suspension is in a class of drugs called penicillin-like antibiotics. It works by stopping the growth of bacteria.

Antibiotics like Polymox Suspension do not work for colds, flu, and other viral infections. Taking antibiotics when they are not needed increases the risk of getting an infection later that resists antibiotic treatment.

How should this medicine be used?

Polymox Suspension (Amoxicillin) comes as a capsule, tablet, chewable tablet, and suspension (liquid) to take by mouth. It is usually taken every 12 hours (twice a day) or every 8 hours (three times a day) with or without food. The length of your treatment depends on the type of infection you have. Take Polymox Suspension at around the same times every day. Follow the directions on your prescription label carefully and ask your doctor or pharmacist to explain any parts you do not understand. Take Polymox Suspension exactly as directed. Do not take more or less, or take it more often than prescribed by your doctor.

Shake the suspension well before each use to mix the medicine evenly. The suspension can be placed directly on the child’s tongue or added to formula, milk, fruit juice, water, ginger ale, or other cold liquid and taken immediately.

The chewable tablets should be crushed or chewed completely before swallowing.

Swallow the tablets and capsules whole with a full glass of water; do not chew or crush them.

You should start to feel better during the first few days of treatment with Polymox Suspension. If your symptoms don’t improve or get worse, call your doctor.

Take Polymox Suspension until you finish the prescription, even if you feel better. If you stop taking Polymox Suspension too soon or miss doses, your infection may not be fully treated and the bacteria may become resistant to antibiotics.

Other uses for this medicine

Polymox Suspension is also sometimes used to treat Lyme disease, to prevent anthrax infection after exposure, and to treat anthrax skin infection. Talk to your doctor about the possible risks of using this drug for your condition.

This medicine may be prescribed for other uses; ask your doctor or pharmacist for more information.

What special dietary instructions should I follow?

Unless your doctor tells you otherwise, continue your normal diet.

What should I know about storage and disposal of this medication?

Keep this medicine in the container it came in, tightly closed, and out of the reach of children. Store capsules and tablets at room temperature and away from excess heat and moisture (not in the bathroom). Liquid medicine should preferably be stored in the refrigerator, but can be stored at room temperature. Do not freeze. Throw away any unused liquid medicine after 14 days.

It is important to keep all medicines out of the sight and reach of children, since many containers (such as those containing weekly pills and those for eye drops, creams, patches and inhalers) are not resistant to children and small children can easily open them. To protect young children from poisoning, always close the safety caps and immediately place the medicine in a safe place, one that is upright and out of their sight and reach. http://www.upandaway.org

Unnecessary medications must be disposed of in special ways to ensure they cannot be consumed by pets, children, and others. However, you should not flush this medicine down the toilet. Instead, the best way to dispose of your medications is through a drug take-back program. Talk to your pharmacist or contact your local garbage / recycling department to find out about take-back programs in your community. See the FDA Safe Drug Disposal website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
