Sopdet- I'm on both, antidepressants and rescue remedy pastells and drops.

Both the doctor and chemist has said that it is 100 percent safe to take on any antidepressant.
With your particular AD they could be fine, but with others they may not. You have checked with your Dr & Chemist.

We have no idea if the OP has an issue with alcohol (as the drops is an alcohol base), what other medication (including normal pain killers). Everything like this needs to be taken into account when a new drug is started, even a herbal remedy.

For example, blood thinning tablets shouldn't be taken with any medication with garlic in it, even high garlic diets can effect it, because garlic is a natural blood thinner.
