What DYTREX is used for
DYTREX belongs to a group of medicines known as Serotonin and Noradrenaline Reuptake Inhibitors (SNRIs). SNRIs are believed to work by their action on serotonin and noradrenaline in the brain.

DYTREX is used to treat:
- major depressive disorder (depression)
- diabetic Peripheral Neuropathic Pain

How to take DYTREX
Follow all directions given to you by your doctor and pharmacist carefully.
How much to take
The usual recommended dose of DYTREX in Major Depressive Disorder or Diabetic Peripheral Neuropathic Pain is one 60 mg enteric capsule taken once daily. The recommended dose of DYTREX in Generalised Anxiety Disorder is between 30 mg and 120 mg, taken once daily.
Your doctor may start you on a lower dose to help reduce side effects.
If you have severe kidney disease, the recommended starting dose of DYTREX is one 30 mg enteric capsule taken once daily.
Take your medicine at about the same time each day.
Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
How to take DYTREX
Swallow the enteric capsule whole with a full glass of water.
Do not open the enteric capsules and crush the pellets inside because the medicine may not work as well.
DYTREX may be taken with or without meals.
If you forget to take DYTREX
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.
Otherwise, take the missed dose as soon as you remember, and then go back to taking your tablets as you would normally.
Do not take a double dose to make up for the dose you missed.
If you are not sure what to do, ask your doctor or pharmacist.
How long to take DYTREX for
The length of treatment with DYTREX will depend on how quickly your symptoms improve.
