How Sinequan Affects Patients
Doxepin is a type of antidepressant that works by decreasing the activity of the brain. It can also help with insomnia and anxiety. It may take two weeks for the antidepressant effects to show, but the sedative effects are immediate. At high doses, it can cause central nervous system depression and its anticholinergic and antiadrenergic effects can limit its efficacy.
How Sinequan works in the body
Doxepin works by blocking histamine receptors in the skin to reduce inflammation. It also works on the central nervous system to increase levels of serotonin and norepinephrine. This helps improve mood and reduce depression symptoms. Doxepin may also desensitize serotonin 1A receptors and beta-adrenergic receptors. It is believed to increase dopamine transmission in the frontal cortex which is thought to help improve mood.

Sinequan Toxicity & Overdose Risk
Doxepin is toxic in high doses, with a lethal dose of 180mg/kg in mice and 147mg/kg in rats. Overdosing on doxepin can cause seizures, heart rhythm problems, loss of consciousness, low blood pressure, central nervous system depression, changes on an EKG, and even death. In fertility studies, doxepin was found to reduce the time of copulation, decrease the number of viable embryos, decrease litter size, and decrease sperm motility. There is no evidence that doxepin causes cancer or mutations.
