Information about taking antibiotics

Antibiotics are medicines that inhibit the growth and/or reproduction of bacteria in your body. They are not effective against viral infections, nor for conditions where infection is a seeming thing. For example, after a myocardial infarction, some people may develop a condition similar to pneumonia. However, it is not associated with an infection. In this case, the patient’s immune system attacks the lung tissue that it was originally supposed to protect: the use of an antibiotic here is pointless and the doctor will prescribe other groups of drugs.

Of course, you should not drink alcohol with an antibiotic. With regard to other drinks, there are also nuances. In pharmacology, there is another drink that can play a cruel joke on you, which is not very obvious at first glance. This is grapefruit juice. It contains substances that affect liver enzymes involved in the neutralization of drugs. Therefore, when taking certain drugs and grapefruit juice at the same time, the drugs may not work as prescribed by doctors. For example, they can be quickly removed from the blood, or vice versa, they can stay there longer than usual, which can lead to poisoning. Accordingly, ordinary water at room temperature should be used to take medicines.

Contraindications of Keflex Generic

Individual intolerance to cephalosporins or penicillins can stand in the way of taking this medication. Hypersensitivity to the components of the drug is also another contraindication.

Only when the intended benefit to the mother surpasses the possible harm to the fetus is it permissible to use the medicine throughout pregnancy and nursing. If prescribed medication is used while nursing, breastfeeding should be terminated.

These are just the most common contraindications. Your medical specialist will advise you on whether your current health condition as well as any of the health issues are a reason to raise a red flag or if they will not stand in the way of your treatment with this medicine.

Drug interactions

Whether or not it is safe to take this antibiotic with any of the other medications should only be decided by your doctor. Most doctors have access to specialized databases in their pockets that help evaluate the interactions and the risks of combining them.

Besides some of the other medications, it is worth noting that antibiotics should not be combined with sorbents – substances that supposedly absorb toxins from the intestines. Along with toxins, these drugs will absorb the antibiotic itself, so it will not be able to provide the help that it is supposed.

Usage instructions

Keflex generic treatment and dosages are determined by the doctor individually, taking into account the severity of the disease, the localization of the infection, the data of bacteriological studies, and the sensitivity of the pathogen.

Usually, you will need to continue taking this medication for 7-14 days, but in the case of severe infectious diseases, long-term therapy is possible. The dosage for adults is usually 250 mg, but it can be doubled. For children, the dosage is notably smaller as it is calculated based on their body weight by giving 25-100 mg per kilogram.

Treatment with the drug should be continued for at least another 48-72 hours after the disappearance of the symptoms of the disease and/or according to the results of bacteriological analysis. Here are some of the other points you should keep in mind before and during the use of this medication:

  • The drug should be taken orally 30-40 minutes before a meal or after a meal, without chewing the capsules and drinking plenty of water.
  • The duration of treatment is determined by the doctor depending on the severity and nature of the infection.
  • It is not recommended to independently change the dosage or stop taking the drug without the consent of the doctor. Early discontinuation may lead to a recurrence of the infection.
  • If you are prescribed several doses a day, distribute them evenly throughout the time you are not sleeping.
  • You should not take a missed dose close in timing when the next dose intake is.
  • Avoid drinking alcohol and medicines containing alcohol while taking Keflex, as this may increase the side effects of the drug.
  • The impaired renal function raises the chance of cumulation of the substance in the body, so correction of the dosing regimen is required.
  • Data show that there is no need to adjust the dosage of the drug in elderly patients. However, it is necessary to take into account age-related changes in kidney function. With a significant violation of it, the dose should be reduced and renal function should be carefully monitored during treatment.
  • If you experience side effects such as rash, itching, or swelling, please consult your doctor immediately.

It is important to remember that these recommendations are general and may change depending on your condition and the nature of the infection. Always follow your doctor’s instructions.
