Sign inBefore taking tryptophan
Before taking tryptophan make sure your doctor or pharmacist knows:
- If you are pregnant, trying for a baby, or breast-feeding.
- If you have a rare condition called eosinophilia-myalgia syndrome.
- If you have ever had an allergic reaction to this or to any other medicine.

How to take tryptophan
- Before starting to take tryptophan, read the manufacturer's printed information leaflet.
- Try to take tryptophan at the same times each day to avoid missing any doses.
- Take tryptophan exactly as your doctor has told you to. The usual dose is two tablets taken three times each day, although your dose may be slightly higher or lower than this.
- If you forget to take a dose, take one as soon as you remember unless it is nearly time for your next dose in which case skip the missed dose. Do not take two doses at the same time to make up for a missed dose.
Getting the most from your treatment
- You must keep your regular appointments with your doctor who will want to check on your progress.
- Suicidal thoughts may be associated with depression and the medicines used to treat it. You may be at risk of such thoughts early in your treatment, after a change in your dose, soon after stopping treatment, if you have previously thought about harming yourself, or if you are a young adult. Tell your doctor straight away if you are having any thoughts of harming yourself.
- If you buy any medicines, check with a pharmacist that they are safe to take with tryptophan.
- If you are having any treatment like an operation or dental treatment, tell the person carrying out the treatment which medicines you are taking.
