Hello. Thank you for using JustAnswer. I am sorry that no one answered you earlier. Since no one answered you in the other section of JustAnswer, they transfered it to another section. That is why I am only able to answer you just now. I hope you are doing ok, since you have had to wait.
Rychol is a nutritional supplement containing ingredients that are not monitored or approved by the FDA.
When looking up the ingredients of Rychol I find that it contains Berberine and COQ10.
Berberine is known to "increase noradrenaline and serotonin levels in the brain (rats) while inhibiting dopaminergic activity.
" (per wikipedia article). It is being studied for use in depression in some countries.
So in fact it is likely that the Berberine in the Rychol is interacting with your Venlor. You must stop the Rychol and contact your doctor. You may need to skip a dose or too of your Venlor as well - but this is up to your doctor and you to discuss, since your doctor has prescribed this medication to you.
If you are extremely panic-y and nervous, you may also need to take an anti-anxiety medication until the Rychol is out of your system.
Please reply if you need more information or have further questions. I will stand by to see if you need further help.
