Do not exceed the stated dose.
Interactions with other medicine
Concavit may react with other medicines you are taking. If
you are taking any of the medicines listed then consult your
pharmacist or doctor.
Contraceptive pills may increase levels of Vitamin A.
Agents such as Bile Acid Resins e.g. Cholestyramine and
Colestipol impair the absorption of fats including the fat
soluble vitamins A and D.
Thiazide diuretics and Vitamin D both increase blood
calcium levels so when used together very high levels of
calcium in the blood may occur.
High blood levels of calcium from the vitamin D
administration may enhance the toxic effects of glycoside
heart drugs (e.g. digoxin).
Vitamin D also enhances magnesium absorption.
Barbiturates or anticonvulsants may reduce the effects of
Vitamin D on the absorption of calcium from the diet and
from resorption from the bones.
Liquid Paraffin taken orally and other agents that affect
the mobility of the gut (e.g. antispasmodics) may interfere
with the absorption of the fat soluble vitamins.
Pyridoxine reduces the effects of L-dopa (usually
prescribed for the treatment of Parkinson’s disease). Your
doctor may also prescribe a medicine known as a dopadecarboxylase inhibitor which helps prevent this
All ages: 0.5ml to be taken by mouth daily.
If you miss a dose take it as soon as you remember unless it is
almost time for your next dose. Do not take a double dose.
Overdose is only likely to occur if doses in excess of those
recommended are taken and/or for prolonged periods. If you
have taken too much Concavit Drops then consult your doctor.
Vitamin A toxicity initially causing irritability, vomiting, loss
of appetite and skin changes has been reported especially in
children. With long term vitamin A overdose liver and brain
disorders may occur. The symptoms usually disappear after
withdrawal of the treatment.
Vitamin D toxicity causes disturbances of calcium metabolism
leading to calcium deposits forming in soft tissue including
the lungs and kidneys. Brain and circulatory damage can also
occur especially in infants. In infants showing increased
Vitamin D sensitivity there is especial risk of elevated blood
Symptoms of elevated blood calcium levels include anorexia,
nausea, vomiting, constipation, abdominal pain, muscle
weakness, thirst, increased urine production, drowsiness,
confusion, calcium deposits in the kidneys and in severe cases
heartbeat disturbances, coma and heart failure.
If you suffer any of these effects or have any other reaction
that you believe may be due to taking Concavit then consult
Some of the non-active ingredients may also cause
undesirable effects. One ingredient is glycerin (sometimes
called glycerol). Glycerin is harmful in high doses. It can
cause headaches and can cause stomach upsets and diarrhoea.
