What Dothep is used for

Dothep belongs to a group of medicines called tricyclic antidepressants (TCAs).TCA medicines work by correcting the imbalance of certain chemicals in the brain.These chemicals, called amines, are involved in controlling mood.By correcting this imbalance, TCAs can help relieve the symptoms of depression.
Ask your doctor if you have any questions about why Dothep has been prescribed for you.
Your doctor may have prescribed Dothep for another reason.
Dothep is not approved for use in children and adolescents below 18 years of age for the treatment of depression.
The safe use and effectiveness of Dothep in treating depression, for this age group, has not been established.
Dothep is available only with a doctor’s prescription.

How to take Dothep

Follow all directions given to you by your doctor and pharmacist carefully.
They may differ from the information contained in this leaflet.
If you do not understand the instructions on the pack, ask your doctor or pharmacist.

How much to take

The dose varies from person to person.
Your doctor will tell you how much Dothep you need to take each day and when to take it.This depends how well you respond to Dothep and whether or not you are taking any other medicines.
The usual starting dose is 25 mg three times daily for one to two weeks.Your doctor may then increase your dose, up to a maximum of 200 mg per day.
Once your symptoms improve, your doctor will then slowly reduce your dose to the lowest effective dose which maintains relief of symptoms.
Elderly people over 65 years of age and those with liver or kidney problems may need smaller doses.

How to take it

Swallow the tablets or capsules with a glass of water.
The 75 mg tablets can be divided in half along the breakline if advised by your doctor or pharmacist.

When to take it

Dothep can be taken as a single dose (e.g. at bedtime) or as divided doses (e.g. three times a day).Your doctor will advise you.
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 long to take it for

Keep taking Dothep for as long as your doctor recommends.
The length of treatment will depend on how quickly your symptoms improve.
Most medicines for depression take time to work, so do not be discouraged if you do not feel better right away.Some of your symptoms may improve in 1 or 2 weeks but it can take up to 4 or 6 weeks to feel the full benefit of Dothep.
Even when you feel well, you will usually have to take Dothep for several months or longer, to make sure that the benefits last.

If you forget to take it

If you forget to take Dothep before you go to bed and wake up late in the night or early in the morning, do not take the missed dose until you have checked with your doctor.
You may have difficulty waking up, or experience drowsiness in the morning and during the day.
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 Dothep 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.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor, or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think you or anyone else may have taken too much Dothep.
Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
Too much Dothep may make you tremble, agitated and/or have difficulty walking. Other signs include fitting or convulsions, unusual muscle movements, difficulty breathing, a very high temperature or irregular heartbeat as well as other serious heart problems.
Keep Dothep out of the reach of children.
Children are much more sensitive than adults to medicines such as Dothep.An accidental overdose is especially dangerous in children.

While you are taking Dothep

Things you must do

Tell your doctor immediately if you have any suicidal thoughts or other mental/mood changes.
Occasionally, the symptoms of depression or other psychiatric conditions may include thoughts of harming yourself or committing suicide.
These symptoms may continue or get worse during the first one to two months of treatment until the full antidepressant effect of the medicine becomes apparent. This is more likely to occur in young adults under 25 years of age.
Contact your doctor or a mental health professional right away or go to the nearest hospital for treatment if you or someone you know is showing any of the following warning signs of suicide:
worsening of your depression
thoughts or talk of death or suicide
thoughts or talk of self-harm or harm to others
any recent attempts of self-harm
increase in aggressive behaviour, irritability or any other unusual changes in behaviour or mood.
All mentions of suicide or violence must be taken seriously.
Families and caregivers of children and adolescents being treated with Dothep need to monitor these patients for the emergence of:
panic attacks
restlessness or difficulty sitting still
unusual changes in behaviour
This will help your doctor determine the best way to control these feelings.
Tell your doctor if you feel Dothep is not helping your condition.
Keep all of your appointments with your doctor so that your progress can be checked.
If you are taking Dothep for a long time, your doctor may ask you to have your eyes tested regularly.

Your doctor may ask you to temporarily stop taking Dothep a few days before elective surgery.
Tell your doctor if, for any reason, you have not taken your medicine exactly as prescribed.
Otherwise, your doctor may think that it was not effective and change your treatment unnecessarily.

Dothep may cause drowsiness, dizziness or light-headedness in some people.If any of these occur, do not drive, operate machinery or do anything else that could be dangerous.

Your doctor may suggest you avoid alcohol while being treated for depression.
Be careful getting up from a sitting or lying position.
Dizziness, light-headedness or fainting may occur, especially when you get up quickly. Getting up slowly may help.
Be careful if you are older than 65 years of age.
Elderly people may become confused when taking Dothep.Families and carers should be aware of this.Special care may be needed.
Tell your doctor or dentist if your mouth continues to feel dry for more than 2 weeks.
Dothep may cause dry mouth.This can be relieved by frequent sips of water, sucking sugarless lollies or chewing sugarless gum.However, continuing dryness of the mouth may increase the chance of dental disease, including tooth decay and gum disease.
