I am taking Nervijen injections for a B12 deficiency and Tryptomer 10 mg for migraines, but I recently started experiencing an irregular heartbeat and fatigue while working. Could these be side effects of my current medications, or what medicine should I take for these symptoms?

Yes, these symptoms could be side effects of your medication. Tryptomer (amitriptyline), even at a low 10 mg dose, is known to cause fatigue and can sometimes cause heart rhythm changes or an irregular heartbeat. Nervijen (Vitamin B12) is unlikely to cause these symptoms. You should not take any new medicine to treat these symptoms yourself. An irregular heartbeat requires immediate medical attention. Please consult your doctor or visit a clinic promptly for an ECG (heart trace) to evaluate your heart rhythm. Your doctor may need to adjust your Tryptomer dose or switch you to a safer alternative for migraine prevention.

Kindly, sir or madam Can I take a 1000 mcg tablet of nethycobalamin for depression and tinnitus?

Methylcobalamin (often 1000 mcg) can be taken safely in many cases and may help if your symptoms are due to vitamin B12 deficiency, which can sometimes contribute to nerve issues and low mood. However, it is not a primary treatment for depression or tinnitus unless a deficiency is confirmed. It?s better to check your B12 levels and consult a doctor before starting, so you get the right treatment for the actual cause.
