Before you start using Keflex, you should alert your personal physician if you are suffering from known allergies to foods, dyes, preservatives or any other type of substances. Before you start taking Keflex you must alert your personal physician if you are suffering from gastrointestinal disease or from kidney disorders. In these cases, you might not be allowed to start taking Keflex, or you might have to be prescribed a slightly lower dose of Keflex. Your personal healthcare provider should regularly monitor your treatment with Keflex.

Intake Guidelines

Follow the exact instructions that your doctor has given you regarding your treatment with Keflex. If you have any further questions, ask your doctor, a pharmacist or a nurse. You should also carefully read the set of instructions that is written on the drug's label. Each dose of Keflex should be accompanied by a large glass of water (about 8 ounces of liquid). You may take Keflex either on a full or on an empty stomach. However, if you start experiencing stomach upset, you should try to take Keflex with food or at least with milk.
If you are following a treatment with the liquid form of Keflex, you should use a dose-measuring device (such as a dose-measuring cup or spoon), to make sure that you are taking in the correct dose of Keflex. If you do not own such a device, you should buy one from your local pharmacy. Before you measure a dose of Keflex you must shake the drug's suspension.
In order to maintain a proper constant concentration of Keflex in your organism, you should evenly space your prescribed doses of Keflex during the day. In order to get the most benefits from your treatment with Keflex, you should take it on a regular basis. You must not stop your treatment with Keflex without your physician's approval, even if you start to feel better after a few days of treatment, because the infection's symptoms might disappear even if the infection has not completely healed.


Ask your doctor to calculate the dose of Keflex that suits you best. The correct dosage varies from one person to another, as it depends on a couple of factors (among them: age, sex, body weight, the severity of your disorder, general health condition, etc). You must not make any alterations to the dose that you have been prescribed by your physician without asking for your physician's consent to do so.


In order to avoid an overdose with Keflex, you must not take in extra doses of Keflex without your personal physician's approval. If you suspect that you might be suffering from an overdose with Keflex, you are in need of medical attention (inform your doctor immediately, contact your local poison control centre). The average Keflex overdose symptoms usually include vomiting, abdominal cramps, diarrhea, seizures, nausea, tingling and numbness in the legs or arms, and even muscle spasms.

Missed Dose

Keflex should be taken in on a regular basis. If you are following a treatment with Keflex, you must try not to miss any of your prescribed doses. If you happen to miss one, you should take it as soon as possible and then continue with your regular schedule. If it is time for another dose, skip the one that you have missed and proceed with your regular treatment. You should not take in a double dose of Keflex without your physician's consent.

Side Effects

A prolonged treatment with Keflex might trigger some severe allergic reactions and side effects such as severe nausea, diarrhea or vomiting; unusual bruising or bleeding; blood or mucous in the stool; and redness, rash, or itching. If you are experiencing any of these side effects you should immediately stop using Keflex and seek emergency medical care.
Keflex's less severe (but more common) side effects are known to include yeast infection of the vagina or of the mouth and mild diarrhea or nausea. If you are experiencing any of these les dangerous side effects you may continue using Keflex. You should alert your personal physician.
