• have ever had any problems with your kidneys;
• have an intolerance to some sugars e.g. lactose.
Taking other medicines
Please tell your doctor before you start to take your capsules if you are taking any of the
following:
• probenecid (used to treat gout)
• aminoglycosides or diuretics, such as furosemide, etacrynic aced or piretanide
• oral contraceptives,(“the pill”) – this medicine may reduce the effectiveness of the pill, so
other precautions, such as condoms should be used.
Tell your doctor if you know you are allergic to other drugs. He or she can then decide
whether it will be safe for you to take Cefalexin Capsules.
If you need to test for glucose in your urine, (for example, because you are diabetic),
Cefalexin Capsules may give a false result.

How to take your capsules
For oral use.
Adults
You must take your capsules are your doctor has told you to. To label will tell you how many
to take and how often to take them. The number of capsules you take is called the “dose”.
The usual daily dosage for adults is 1g-4g, in divided doses. However, for most infections,
500mg every 8 hours is effective.
For certain infections such as skin, throat and urinary (i.e. painful when passing water)
infections, your doctor may tell you take 250mg every 6 hours, or 500mg every 12 hours.
If a daily dose of more than 4g is required your doctor may provide you with an ‘injectable’
dose of the drug.
Patients with kidney problems
Your doctor may reduce your dose.
Elderly patients
If you are elderly you should take the normal adult dose, unless you have severe kidney
problems, when the dose may be lower.
Children
Children can take Cefalexin Capsules. Your doctor will work out the correct dose for them
depending on their weight. The usual daily dose is 25mg to 60mg for each kilogram of their
weight. The daily dose is usually split up into smaller amounts and taken every 8 or 12 hours
i.e. 250mg every 8 hours. If the child is taking Cefalexin Capsules for an ear infection, he or
she may have to take 75mg to 100mg for each kilogram of their weight, split up into four
doses throughout the day. The maximum dose for children is 4g/day.
Higher doses may be required for more serious infections.
Swallow the capsules whole with water. Take all the capsules your doctor has given you.
Do not stop taking them just because you feel better.
If you forget to take a dose at the right time, take it as soon as you remember. Do not take
two doses together.
If it is almost time to take the next dose, wait until then and then carry on as before.
What to do if you take too many capsules
It is important not to take too many capsules.

swallowed too many capsules or if you think a child has accidentally swallowed any.
