WHAT IS IN THESE TABLETS?

Each white round coated tablet contains 250 mg of naproxen, which is the
active medicine. The tablets come in a box of 9 tablets. The tablet is gastroresistant (also known as enteric coated). This means that it is covered with a
coating which stops the tablet dissolving in the stomach, so that the naproxen
is released further down in your gut.
The tablets also have inactive contents: lactose, maize starch, polyvidone,
sodium starch glycollate and magnesium stearate. Also, the coating contains
colloidal silicon dioxide, polyvinyl acetate phthalate, polyethylene glycol,
stearic acid, hydroxypropyl methylcellulose, sodium alginate, sodium
bicarbonate, purified talc, triethyl citrate, the colour titanium dioxide (E171)
and black printing ink.
