Other medicines and Clasteon
Tell your doctor or pharmacist if you are taking or have
recently taken any other medicine including those
obtained without a prescription. This is particularly
important if you are taking any of the following:
● antibiotics
● non-steroidal anti-inflammatory medicines such as
ibuprofen or diclofenac
● antacid indigestion tablets
● mineral supplements
● estamustine, used to treat prostate cancer.

Pregnancy and breastfeeding
Clasteon Capsules are not normally given to people
during pregnancy. If you think you might be pregnant or if
you are planning a family, tell your doctor before taking
this medicine.
Do not breastfeed while you are taking Clasteon

Always take the capsules as your doctor tells you to.
Clasteon is for use in adults only.
The usual dose is 4 capsules daily taken as a single dose
or, if more than 4 capsules, divided into two doses. Your
doctor may tell you to take fewer than 4 capsules, but no
more than 8 capsules daily.
● Swallow the capsules whole, with water (NOT milk see below)
● Single daily dose: Take in the morning on an empty
stomach, with a glass of water. Do not eat, drink
(except water) or take any medicines for 1 hour after.
● Twice daily dose: Take the first dose as above.
Take the second dose between meals, more than 2
hours after and 1 hour before eating, drinking
(except water) or taking any other medicines.
● Make sure you drink a lot of fluid (water or diluted
squash) during treatment with Clasteon.
Clasteon should not be taken with food or with drinks
containing milk as it is harder for the medicine to be
absorbed into the blood and so it does not work as well.
If you forget a dose take it as soon as possible.
However, if it is nearly time for your next dose, skip the
missed dose and carry on as before. Do not take a
double dose.
If you take too many Clasteon Capsules or someone
else accidentally takes your medicine, contact your
doctor, pharmacist or nearest hospital immediately.
Symptoms of an overdose may be a feeling of sickness,
or being sick (nausea or vomiting).
