What about alcohol?
It is officially recommended that people taking nefazodone should not drink alcohol. This is because both nefazodone and
alcohol can cause drowsiness. If the two are taken at the same time, severe drowsiness can result. This can lead to falls or
accidents. As well as this, drinking alcohol often makes depression worse. Excessive drinking is especially likely to do this.
Once people are used to taking medication, they can sometimes drink alcohol in small amounts without any harm. Avoid
alcohol altogether for the first one or two months. After this, if you want a drink, try a glass of your normal drink and see
how you feel. If this doesn’t make you feel drowsy, then it is probably OK to drink small amounts. It pays to be very cautious
because alcohol affects people in different ways, especially when they are taking medication.
Don’t stop taking your medication because you fancy a drink at the weekend. If you do drink alcohol, drink only small
amounts. Never drink any alcohol and drive while on nefazodone. Discuss any concerns you may have with your
pharmacist, nurse or doctor.
When I feel better, can I stop taking nefazodone?
No. If you stop taking nefazodone, your original symptoms may return. To reduce your chances of becoming depressed
again, you may need to take your antidepressant for at least 6 months after you feel better, and sometimes longer. This is
not thought to be harmful. You should decide with your doctor when you can come off it.
