Thoughts of suicide and worsening of your depression or anxiety disorder
If you are depressed and/or have anxiety disorders you can sometimes have thoughts of
harming or killing yourself. These may be increased when first starting antidepressants, since
these medicines all take time to work, usually about two weeks but sometimes longer.
You may be more likely to think like this:
- If you have previously had thoughts about killing or harming yourself.
- If you are a young adult. Information from clinical trials has shown an increased risk of
suicidal behaviour in adults aged less than 25 years with psychiatric conditions who were
treated with an antidepressant.
- If you have thoughts of harming or killing yourself at any time, contact your doctor or go to
a hospital straight away.
You may find it helpful to tell a relative or close friend that you are depressed or have an
anxiety disorder, and ask them to read this leaflet. You might ask them to tell you if they think your
depression or anxiety is getting worse, or if they are worried about changes in your behaviour.
Pregnancy and breast-feeding
If you are or think you might be pregnant or you plan to become pregnant, or if you are breastfeeding you must tell your doctor before you take this medicine. Your doctor will decide if you
can take these tablets.
Driving and using machines
These tablets can make you feel drowsy. Do not drive, operate machinery or do anything that requires
you to be alert until you know how the tablets will affect you. Feeling drowsy in the day can improve
with time, but if drowsiness becomes a problem, you should tell your doctor.
If you drink alcohol with these tablets this can make the feeling of drowsiness worse.
Important information about some of the ingredients of Prothiaden tablets
These tablets contain a sugar called sucrose. If you have been told by your doctor that you
have an intolerance to some sugars, contact your doctor before taking this medicine. They also
contain a colour called sunset yellow which may cause allergic reactions.
3. HOW TO TAKE PROTHIADEN
Your doctor will tell you how many tablets to take and when you should take them. This will
also be on the carton label. Ask your pharmacist or doctor for help if you are not sure how to
take your tablets or if you want more information. The following information is given as a guide
The tablets should be swallowed whole with a drink of water. Do not chew the tablets as you
may get a bitter taste in your mouth and a temporary numbness of your tongue.
Adults: The usual starting dose is 1 tablet a day. Your doctor may ask you to increase this to
2 or 3 tablets a day. Your doctor will tell you if you should take the tablets as separate doses
throughout the day, or a single dose each evening, usually a couple of hours before you go to
bed. Normally, not more than 3 tablets should be taken each day.
Elderly: The usual starting dose is 1 tablet a day.
It may take two to four weeks of treatment before you begin to see an improvement in your mood
although you might feel there is an improvement in your anxiety symptoms before then. It is
important that you keep taking these tablets until your doctor tells you to stop.
If you stop taking Prothiaden
Do not stop taking these tablets just because you feel better. If you stop taking the tablets too
soon, your condition may get worse. If your doctor wants you to stop taking these tablets, your
doctor will ask you to stop gradually.
If you forget to take Prothiaden
Do not worry. Simply leave out that dose completely and then take your next dose at the right
time. Do not take a double dose to make up for a forgotten tablet. If you are unsure, check again
with your doctor or pharmacist.
If you take more tablets than you should
You should only ever take the number of tablets that your doctor has told you to take. Do not
change the dose yourself. If you think your tablets are not working well enough, speak to your
doctor to see if the dose can be increased.
These tablets may seriously harm you and may be life threatening if you take too many tablets.

accidentally takes too many tablets. Remember to take the pack with you, even if it is
