Mechanism and Effectiveness of Cephalexin

Cephalexin is a medication that belongs to a group of drugs called antibiotics, namely cephalosporins. Their effects and actions are quite similar to penicillin because they work by slowing down or stopping the growth of harmful bacterial cells, thus, preventing them from forming the new ones. Without cell walls, bacteria can’t survive, and this is how this medicine cures patients. Its use was approved by the FDA in 1971, and now Cephalexin is often prescribed and taken to treat different infections caused by bacteria susceptible to its action and effects. For example, this medication can treat specific infections of the middle ear, bronchitis, tonsils, pneumonia, bone infections and some others.

Possible Side Effects

The use of Cephalexin may cause certain adverse effects, just like other drugs, including:

  • Nausea and diarrhea;
  • Headaches and abdominal pain;
  • Vomiting and fever;
  • Dizziness and skin rash;
  • Vaginitis and abnormal liver tests.

The good news is that most of these symptoms are mild and quite rare. Besides, those patients who have any allergic reaction to penicillin may develop allergies to Cephalexin, including seizures and anaphylaxis. If you notice any signs of allergies or other serious side effects, you need to contact your doctor at once.

Available Preparations and Recommended Doses

Nowadays, it’s possible to find Cephalexin as special powders for suspensions, standard tablets and capsules that all come in different strengths to add more convenience to patients. When it comes to regular doses, adults need to take 1-4 g in divided doses, and their standard dosage is 250 mg of Cephalexin taken every 6 hours. However, there are some bacterial infections that should be treated by taking 500 mg each 12 hours. The recommended dosage of children is decided according to their body weight, and they also need to take their prescribed doses in regular intervals based on seriousness and types of their infections.

Dangerous Drug Interactions and Important Precautions

There are certain medications that shouldn’t be combined with Cephalexin because of possible drug interactions. For instance, it may decrease the effectiveness of BCG and different typhoid vaccines, so its use shouldn’t be combined with them. Before starting this treatment, you need to inform your doctor about any other meds and other pharmaceutical products that you’re taking to avoid drug interactions.

Finally, you also need to take other important precautions to undergo this treatment safely. Pregnant and nursing women should be careful when taking Cephalexin. All patients should inform their healthcare specialists if they have any allergic reactions and other important medical conditions, including stomach and kidney diseases. When using its liquid form, you should be careful if you have diabetes, because it may contain sugar. Start taking Cephalexin when it’s clearly needed to avoid its misuse.
