Generic Keflex (Cephalexin 250 mg) guide:
What is Keflex?
Keflex is a brand name of the antibiotic drug that has been used since the 1960s. The antibiotic itself is named Cephalexin. It is currently manufactured and marketed by numerous manufacturers who either leave the original name of the substance to sell the drug or come up with their own trade names. Such drugs are collectively called generics. They are usually much cheaper than the brand drugs, especially, if they are sold in the developing world.
Cephalexin is a beta-lactam antibiotic, i.e. it is included in the class of broad spectrum antibiotics that have beta-lactam ring in their formula. It is a first generation cephalosporin that works almost the same as the other drugs from this group but its main advantage is that it renders the same effect when taken orally. The medication treats Gram-positive and some Gram-negative bacteria and is used in the therapy of infections of various body organs.
Does Generic Keflex provide the same effect as the branded drug?
In general, generics were created to make essential medications affordable to anyone. As Cephalexin is included in the List of Essential Medicines by the World Health Organization, it is one of the drugs that are available in any corner of the world either in a form of branded drug or generic. Perfectly, generics should be absolutely equal to the branded drugs by the formula, quality of ingredients, and of course, efficacy and safety. However, some manufacturers in order to cut the production costs use inferior ingredients. To avoid purchasing the bad quality drug, you should buy Generic Keflex from a reputable seller, for instance, like our online pharmacy about which service and quality of the medications you can find multiple reviews.
When the therapy with the drug is prescribed?
You can buy Keflex or a generic version of the drug when your doctor prescribes you any antibiotic based on Cephalexin. The drug is prescribed in pathologies of respiratory tract caused by the pathogen susceptible to Cephalexin such as bronchitis, pneumonia, abscess of lungs, pleurisy; otitis media, pharyngitis, tonsillitis, and others; urinary tract infections such as cystitis, pyelonephritis, and others; infections of the reproductive system vulvovaginitis, endometritis, Epididymitis, and others; skin infections such as phlegmon, pyoderma, abscess, furunculosis, and others; infections of the musculoskeletal system such as osteomyelitis, and different types of arthritis.
If you don’t have a precise diagnosis and hadn’t made a susceptibility test to find out whether the disease you suffer from is caused by a bacteria sensitive to the antibiotic, you shouldn’t order Cephalexin. It is necessary to get the direct indication and instruction from your doctor before you start using any antibiotic drug because their incorrect use can cause serious health damage and result in superinfection development, i.e. the infection that would be much harder to treat and would require the use of more potent and harmful antibiotics.
Treatment courses and dosages of Cephalexin for different infections
The instruction recommends for adults to use the drug in the dosage of 1-4 grams a day if the infection is caused by Gram-positive bacteria. In the case of Gram-negative bacteria, the dosage can be increased to 4-6 grams a day. The daily dosage is divided into several intakes with an interval of 6 hours. The standard treatment course is one to two weeks.
For children, the instruction recommends 25-50 milligrams per kilogram of the body weight in the case of Gram-positive bacteria. If the disease is caused by Gram-negative bacteria, the dosage can be increased to 100 mg a day.
In uncomplicated infections of urinary tract, skin, soft tissue or pharyngitis, the daily dosage can be divided into two intakes with an interval of 12 hours.
The drug should be taken for 2-5 days after the symptoms elimination.
Generally recommended dosages for adults for various infections:
– Treatment of otitis media: 0.5 grams (500 mg) taken 3 times a day with an interval of 6 hours. The treatment course is from 10 to 14 days.
– Therapy of pharyngitis: 0.25 grams (250 mg) taken 3 times a day with an interval of 6 hours or 0.5 grams (500 mg) taken 2 times a day with an interval of 12 hours.
– Treatment of prostatitis: 0.5 grams (500 mg) taken 3 times a day with an interval of 6 hours. The treatment course duration is 14 days.
– Treatment of pyelonephritis: 0.5 grams (500 mg) taken 3 times a day with an interval of 6 hours. The treatment course is for 14 days.

Cephalexin adjustments of dosages
If you have mild to moderate liver function impairment, you can use standard dosages of the drug. If you have kidney function impairment, before you buy Cephalexin you need to undergo tests to identify your creatinine clearance rate so that your doctor will be able to choose the correct dosage and intake regimen. For example, in creatinine clearance from 10 to 40 milliliters per minute the standard dosage should be taken every 8 to 12 hours. In creatinine clearance below 9 milliliters per minute, the standard dosage is taken with an interval of 12 or 24 hours.
How Cephalexin acts?
The drug has bactericidal effect; it disrupts the synthesis of the cell wall of microorganisms. It is effective against a wide range of organisms including Staphylococcus, Streptococcus, Pneumococcus, Escherichia coli, Salmonella, Shigella, Haemophilus influenza, and others. The medication is ineffective against Mycobacterium tuberculosis, enterococci, and enterobacter.
Cephalexin is quite promptly absorbed from the gastrointestinal tract. The max concentration in the blood plasma is achieved 1-1.5 hours after the pill intake. The drug penetrates all organs, tissues, and fluids. The drug is excreted predominantly through urine.
Is Cephalexin safe during pregnancy?
The drug can be used in pregnant women but only under a doctor’s supervision. The drug penetrates the breast milk; therefore, it is better to avoid using it during lactation.
Contraindications for Cephalexin use
The drug is contraindicated in intolerance of cephalosporins and penicillin antibiotics, given the possibility of cross-allergy.
Adverse effects that can occur during the treatment
When you order Keflex and start using it, you need to be prepared that you may develop certain unpleasant side effects such as dyspepsia (indigestion, heartburn, etc.), diarrhea, and in very rare cases, pseudomembranous colitis. Other possible adverse reactions include allergic reactions, general weakness, changes in blood indicators, dizziness, tremor, and others.
Regardless of the type of side effects, if you have any negative symptoms using the medication, you should inform your doctor immediately.
Combination of Keflex pills with other drugs
The antibiotic has a bactericidal effect. Therefore, it is useless to take it along with antibiotics that render bacteriostatic action (for example, tetracycline antibiotics and chloramphenicol).
The drug should be cautiously used with nephrotoxic drugs (aminoglycosides, polymyxin) and loop diuretics (ethacrynic acid and furosemide).
Some other drug interactions influence the blood indicators and excretion time of the antibiotic. Therefore, if you use any medicines or plan on using any when you buy Generic Cephalexin, make sure to consult your doctor on their compatibility first.
Overdose detection and treatment
The common symptoms are nausea, vomiting, pain in the stomach, and diarrhea. If the symptoms are mild, you can use activated carbon at home and wait for the symptoms to be gone. If the symptoms are moderate to severe, you need to seek medical assistance as symptomatic therapy and monitoring of vital functions could be needed.
