Key takeaways
Doxepin (Silenor) and imipramine are both tricyclic antidepressants (TCAs) used to treat different conditions. Doxepin is primarily used for insomnia, specifically to help you stay asleep, while imipramine is used for depression and can also help with bedwetting in children. Doxepin is available as a tablet taken once daily before bedtime, whereas imipramine comes in both tablet and capsule forms, with dosing that can be split throughout the day or taken as a single dose at bedtime. Both medications are available as a lower-cost generic. Doxepin's common side effects include sleepiness and tiredness, while imipramine can cause dry mouth, dizziness, and weight changes. Imipramine can be taken with or without food, while doxepin should be taken on an empty stomach, at least 3 hours before or after eating. Both medications can increase the risk of developing or worsening glaucoma. They may also increase the risk of heart problems.

Imipramine is a medication that's used to treat depression. It can also temporarily help with bedwetting in children at night. Imipramine belongs to a class of medications called tricyclic antidepressants (TCAs). There are two different forms of the medication: imipramine hydrochloride and imipramine pamoate. They used to be available under the brand name Tofranil but are now only sold as generic versions. The dosage generally depends on why you need imipramine, how severe your symptoms are, and your age. It's generally not a first-choice option because it can cause a lot of side effects, like sleepiness, dizziness, dry mouth, and changes in weight.
