Re: When Citalopram stops working... what next?

Most days I have that feeling of being on the edge of bursting into tears, along with uncontrollable health anxiety
...So, what's next? CBT seems to be ineffective for me too - I just can't make it work.
Health anxiety is on the Obsessive-Compulsive Disorders spectrum and while as a generalisation no antidepressant is intrinsically better than any other, either generally or for a specific disorder, the exception to the rule seems to be the SSRI fluvoxamine (Luvox) and the TCA anafranil (Clomipramine) for OCD spectrum. If upping the citalopram isn't on the cards, or doesn't work then I think switching to anafranil is the better option, especially if there are other health issues as fluvoxamine interacts with many other meds which can complicate treatment. Anafranil also has the advantage of inhibiting noradrenaline/epinephrine reuptake in addition to serotonin.
BTW - A number of small scale studies have found the amino acid analogue supplement N-acetylcysteine (NAC) can reduce OCD intrusive and compulsive thought patterns and also boost the effectiveness of antidepressants for OCD and other OCD spectrum disorders [1]. There is a large scale multinational study currently underway to test this. NAC is generally a safe supplement with few side-effects. It is mostly used medically to protect the liver in cases of paracetamol, aka acetaminophen, overdose and has other medical uses. Doses of 1,800-3,000mg/day taken in 3 divided doses seems to work (start with one dose per day of around 500-600mg and increase by the same amount every 2-3 days to avoid triggering diarrhoea). NAC is best taken on an empty stomach about an hour before meals.
As an added bonus NAC may also reduce blood coagulation which seems to be one of the most serious symptoms of Covid-19 (Youtube, 7:57m)
HOWEVER, be aware that a study [2] found NAC (also Vitamin E) may increase the risk of lung cancer in smokers, or those with some specific lung diseases (note, it doesn't cause lung cancer, only maybe reduces the ability of the immune system to detect and destroy existing cancerous cells). This finding has been the subject of much debate because there are many other studies showing NAC protects against lung cancer so it is probably not the final word on the subject. FWIW, I'm a lung cancer survivor and have take NAC for over 14 years because it is the best thing I've found for reducing fluid build up in my remaining lung.
Seek your GP's advice before taking NAC. While it can be beneficial for asthmatics with fluid buildup in lungs, it may cause shortness of breath in some, so caution is needed if you have asthma. It is contraindicated for those taking nitroglycerin, vitamin K and some blood pressure meds.
