Hi -

Using alcohol in conjunction with nortriptyline is risky, and there are specific recommendations against doing so. Both substances are metabolized by the liver and excreted in the urine, although that's not the primary reason to avoid using them at the same time. Using alcohol with nortriptyline can result in potentiating the side effects of nortriptyline; the central nervous system effects and the cardiovascular effects are most notable, but excessive use of alcohol can result in suicidal thoughts and attempts, or in overdosage of nortriptyline. Central nervous system effects can include dizziness, confusion, headache, anxiety, nervousness, panic, tremors, overstimulation, weakness, fatigue, insomnia, nightmares and/or memory impairment. Cardiovascular effects may include orthostatic hypotension (dizziness or fainting on standing, or sitting if the person had been lying down), heart racing, and/or irregular heartbeat. Other effects that may be increased are dry mouth, sedation, increased appetite and constipation. Finally, alcohol can trigger migraines.

Nortriptyline has a half-life (the time it takes for about half the medication to clear from your system) of between 16 and 90 hours; the higher the dose, the longer the half-life. The maximum recommended dosage is 150mg per day in divided doses. Since you take 100mg, the half life would be quite long. The time for the medication to clear entirely would take considerably longer. If you're thinking of discontinuing the medication, it would be best to discuss that with your doctor before doing so.

I hope you have a very enjoyable, alcohol-free birthday! Good luck.
