Cefadroxil

Recognized as a cephalosporin antibiotic, Cefadroxil is used to treat various different types of bacterial infections.

Overview

As an antibiotic, patients are prescribed Cefadroxil when they are suffering from a bacterial infection. Although Cefadroxil can be used to treat any type of bacterial infection, it is routinely prescribed to treat infections of the urinary tract, skin, throat and/or tonsils. It can also be used to treat infections to the sinuses, windpipe, ears, kidneys, bone and/or joints.

Cefadroxil may also be used to prevent infections occurring in some patients. If an individual has an established heart condition and is allergic to penicillin, for example, Cefadroxil may be given prior to any surgery in order to prevent a bacterial infection from developing.

In order to take effect, the cells of bacterial infections must replicate. As this happens, more bacterial cells emerge and the infection worsens. By interfering with the way the bacterial replicates, Cefadroxil effectively prevents the infection from getting worse and kills the bacteria which is present.

If the bacteria is to survive, the cell walls must prevent anything from invading the cell and also stop the contents of the cell from leaking. Cefadroxil prevents bacterial cell walls from forming correctly and, therefore, inhibits the efficacy of the bacteria. Once the cell walls have been weakened, Cefadroxil kills the bacteria and, therefore, the infection and this enables the patient to recover from their illness.

As Cefadroxil can be used to treat numerous different types of bacterial infections, it is widely used. It should be noted, however, that Cefadroxil should only be used to treat infections which are bacterial in nature, as the medication will not have an effect on viral and/or fungal infections.

If a patient is diagnosed with a bacterial infection, a short or moderate course of Cefadroxil may be used in order to rid the body of infection. Once treatment is complete, patients do not typically require further treatment and the vast majority of individuals are able to make a swift recovery.

Conditions Treated:

  • Bacterial Infections

Type of Medicine:

  • Cephalosporin Antibiotic

Side Effects:

Whenever medication is prescribed to a patient, there is a chance that they could experience side-effects when taking it. Although the majority of side-effects are fairly mild, patients should seek medical advice if they feel the side-effects are severe or debilitating.

When taking Cefadroxil, patients may experience the following side-effects:

  • Acid or sour stomach
  • Belching
  • Thick, white vaginal discharge with no odor or with a mild odor

If patients do experience these side-effects, they can seek help and advice from their doctor or pharmacist. Often, additional treatments are available to reduce the impact of any side-effects which occur when taking antibiotics, such as Cefadroxil.

If patients wish to take additional medications in order to treat the side-effects associated with Cefadroxil, they should discuss this with their doctor and/or pharmacist first. In some cases, standard remedies may not be appropriate when taking Cefadroxil. Patients should not, therefore, by over-the-counter medication to take alongside the antibiotic, unless they have sought medical advice first.

If patients experience any other side-effects when taking Cefadroxil, they should consult their physician and/or pharmacist. In addition to this, they may wish to report them to the Food and Drug Administration on 1-800-FDA-1088.

Dosage:

When Cefadroxil is prescribed, physicians will determine the dose by assessing the patient’s current condition. The appropriate dose of medication may depend on various factors, such as the severity of the infection, the patient’s weight, and their medical history.

The dose may also be dependent on the format the medication is prescribed in. Although most patients receive Cefadroxil in tablet form, it is also available in powder for use as a solution and a capsule.

Every time medication is prescribed, patients will be given dosage instructions by their physician. These instructions are tailored to their needs and should be followed at all times. If patients are concerned about their treatment, they should seek medical help before adjusting the dose.

Although every patient will receive specific dosage instructions, a typical dose of Cefadroxil is 1000-2000mg per day for adult patients. Thye may be advised to take this amount as one dose or told to split the dose and take the medication twice daily.

If Cefadroxil is prescribed to children, the standard dose will depend on their weight. In most circumstances, a dose of 30mg per kg of body weight will be given. Once again, patients may be given the daily dose in one sitting or advised to split the dose and take the medicine twice daily.

In most instances, Cefadroxil can be taken with or without food. If Cefadroxil has been prescribed in a liquid form, it’s essential that patients measure the dose appropriately. Using a designated medicine spoon, medical syringe or medicine cup will enable the patient to measure the liquid correctly, whereas regular household spoons will not provide an accurate measure of Cefadroxil.

When taking antibiotics, it’s important that patients follow the instructions they have been given. Even if they begin to feel better while taking the medication, it’s vital that they finish the course of treatment. Unless they have been advised to discontinue the medication by a physician, patients should always complete the treatment with Cefadroxil as failure to do so can lead to a recurrence of infection and antibiotic resistance.

If a patient misses a dose of Cefadroxil, they should take it as soon as it is possible to do so. If the next dose is almost due, however, they will need to skip the missed dose completely and take their next dose as normal. Patients should not take a double dose of antibiotics unless they are advised to do so by their doctor. If patients are unsure how to proceed with their dosage regime, they can seek advice from their doctor and/or pharmacist.

Potential Drug Interactions:

When taking Cefadroxil alongside other medications, it is possible that interactions will occur. Although this may not prevent the medicine from being prescribed, patients may experience an increase in side-effects when taking the following medications in conjunction with Cefadroxil:

  • Cholera vaccine
  • Ethinyl estradiol
  • Pemetrexed
  • Levonorgestrel
  • Norethindrone
  • Desogestrel
  • Probenecid
  • Entecavir
  • Bumetanide
  • Drospirenone
  • Levomefolate calcium
  • Mycophenolate mofetil
  • Chloramphenicol
  • Balsalazide
  • Furosemide
  • Torsemide
  • Ethacrynic acid
  • Warfarin
  • Norgestimate
  • Folic acid
  • Mycophenolic acid
  • Typhoid vaccine
  • Indium Oxyquinoline in-111
  • Norelgestromin

Due to the possibility of interactions occurring, patients should inform their physician of any other medications they are taking before using Cefadroxil. Similarly, patients should seek medical advice before taking any over-the-counter medications, vitamins and/or supplements when taking antibiotics, such as Cefadroxil.

Warnings:

If patients are due to undergo any medical tests, they must inform the relevant medical professional that they are taking Cefadroxil or that they have taken Cefadroxil recently. The medication may affect the results of any medical tests so physicians should be aware if patients are taking the medicine.

Normally, patients should experience some relief from their symptoms within a few days of taking Cefadroxil. If symptoms do not improve or if they begin to worsen, patients should seek medical advice from their doctor.

Cefadroxil is a suitable medication for most patients and it can be given to elderly or geriatric patients. As older people may experience age-related kidney or liver problems, however, it can take longer for the medicine to be absorbed and voided from the body. Due to this, older patients may be given a lower starting dose than is standard.

Cefadroxil is classified as a category B drug by the Food and Drug Administration. Based on this, it is not thought to represent a significant risk to pregnant women or their unborn fetus. Patients should inform their physician if they are pregnant before taking the medication, however, and if patients become pregnant whilst taking Cefadroxil, they should seek medical advice.

When breastfeeding, it is possible for Cefadroxil to be passed from the mother to the infant. Due to this, patients may need to refrain from breastfeeding whilst they are receiving treatment. Patients should seek medical advice from their doctor or physician before breastfeeding whilst taking this medication.

If patients have any of the following conditions, they may be unable to take Cefadroxil:

  • Colitis or gut inflammation
  • History of severe diarrhea
  • Kidney disease or poor kidney function

Although the presence of these conditions may rule out Cefadroxil as a suitable medication, physicians may be willing to prescribe Cefadroxil to patients with these conditions in some cases. A lower dose of the medicine may be given, for example, or additional monitoring may take place while the patient is taking Cefadroxil.

Storage

In most cases, patients will be prescribed Cefadroxil for home use and will, therefore, be required to store the medicine at home. When doing so, patients should ensure that Cefadroxil is in a secure location and that it cannot be accessed by pets or children.

Although the oral solution should generally be kept in a refrigerator, other forms of Cefadroxil can typically be kept at room temperature. The medicine should not be frozen and it should be kept away from moisture, heat and direct light.

If the patient is advised to stop taking Cefadroxil, they should seek medical advice regarding the safe disposal of the medicine.

Summary

Bacterial infections are not uncommon and most people will experience one or more of these conditions throughout their lifetime. With the appropriate treatment, bacterial infections can normally be treated quickly and effectively, without any long-term complications occurring.

Cefadroxil is a first-choice medication due to its effectiveness. As well as working quickly, the medicine can be used to treat various different types of infections. In addition to this, Cefadroxil has relatively few contra-indicators which means that it is an appropriate form of treatment for the majority of patients.
