Mental Health Home > Vivactil Side Effects
Possible Vivactil side effects include weight gain or weight loss, flushing, and difficulty urinating. Although side effects of the medication are generally minor and easily treated, certain problems may require immediate medical attention. Let your healthcare provider know right away if you develop serious side effects of Vivactil, such as changes in heart rhythm, fast heart rate, seizures, or any breast changes.
As with any medicine, side effects are possible with Vivactil® (protriptyline hydrochloride). However, not everyone who takes the medication will experience side effects. In fact, most people tolerate it quite well. If side effects do occur, in many cases, they are minor, meaning they require no treatment or can easily be treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Vivactil. Your healthcare provider can discuss a more complete list of Vivactil side effects with you.)
Vivactil has been studied thoroughly in clinical trials, in which a group of people taking the drug have side effects documented and compared to another group not taking the medicine. This way, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine.
In these studies, some of the side effects of Vivactil included:
- Dizziness or lightheadedness
- Difficulty urinating
- Dry mouth (see Vivactil and Dry Mouth)
- Weight gain or weight loss (see Vivactil and Weight Gain)
- Erectile dysfunction (ED or impotence) or changes in sex drive (see Vivactil Sexual Side Effects)
- Changes in blood sugar levels
- Increased sweating
- Shakiness (tremor)
- Nausea and vomiting
- Hair loss
- Flushing (redness of the skin, especially the face).
Vivactil seems less likely to cause drowsiness than other tricyclic antidepressants.
Withdrawal side effects have been reported in people who have stopped taking the drug suddenly. Side effects of Vivactil withdrawal include:
- A general ill feeling
