Good evening,
I took the trouble to check the literature regarding your question. Here is what I found that applies to your situation
Chamomile: Short term use only, moderate interaction with amitryptiline
Lemon balm: Short term use only, moderate interaction with amitryptiline
Lavender: Short-term use (up to 12 weeks), moderate interaction with amitryptiline
Linden: No data regarding duration of use or interactions
Passionflower: Short-term use only, moderate interaction with amitryptiline
Skullcap: No data regarding duration of use or interactions
Melatonin: Use for up to 6 months, moderate interaction with amitryptiline
Moderate interaction implies that these products increase the sedative effects of amitryptiline. All of these products combined together increase the risk of excessive drowsiness or may cause residual drowsiness during your day the next day
I hope that answers your question,
Jean-Sébastien Lecompte, pharmacist
