Never stop, pause, reduce, or change a prescribed medicine because of anything on this page. Some of the medicines listed here are dangerous to stop suddenly, and the condition being treated does not pause while you experiment. Everything here exists to make your next conversation with a prescriber more specific — not to replace it.

Aplenzin and sexual side effects
Aplenzin is a brand name for bupropion, which belongs to the class this site calls Bupropion. Everything below describes that class.
This page exists because people search for a medicine by name, not by drug class. Everything below describes the class this medicine belongs to. Nothing here says this particular medicine is better, worse, or different from the others in its class — this site does not rank medicines against each other, and that is a conversation for whoever prescribed it.
How this class affects sex
Bupropion works on dopamine and noradrenaline rather than serotonin, and it is consistently the antidepressant with the lowest reported rate of sexual side effects. Some people report the opposite of the usual pattern — desire returning rather than fading. It is not free of effects, and it is not suitable for everyone, which is a prescribing conversation rather than a preference.
What the rating means: For the symptoms this site covers, this class more commonly improves things than worsens them. It still has its own effects to discuss.
What is reported
Editorial categories for the class, not percentages, and not a prediction about you. Published rates vary enormously depending on study design and on whether anyone thought to ask the question.
Wanting sex less often, or losing the spontaneous interest that used to arrive on its own. This is the effect people most often assume is psychological and most often is not only psychological.
Reaching orgasm needs far more time or stimulation than before. Some people find this a welcome effect and some find it exhausting; both reactions are worth saying out loud.
Erections that are slower, softer, or do not hold. Because this depends on blood vessels and nerves, it can also be an early signal of something cardiovascular — which is why it is worth a clinical conversation rather than only a product.
When it tends to show up
Where desire changes for the better, people usually notice over weeks rather than days. If sexual function got worse rather than better after starting it, that is worth reporting — it is the less expected direction.
What helps without touching the medicine
If sexual function is a priority for you, say so explicitly at the review — it is a factor prescribers can weigh, but only if they know it matters to you.
Worth asking whoever prescribed it
Is sexual function something you can factor into which antidepressant we use?
Aplenzin is a brand name for bupropion, which belongs to the class this site calls Bupropion. Everything below describes that class. For the symptoms this site covers, this class more commonly improves things than worsens them. It still has its own effects to discuss.
Can bupropion affect your sex life?
More often helps for this class. Bupropion works on dopamine and noradrenaline rather than serotonin, and it is consistently the antidepressant with the lowest reported rate of sexual side effects. Some people report the opposite of the usual pattern — desire returning rather than fading. It is not free of effects, and it is not suitable for everyone, which is a prescribing conversation rather than a preference.
Does bupropion improve anything?
For many people it improves lower sexual desire. That is the more usual direction for this class, which is why a change in the opposite direction is worth reporting.
How soon would bupropion cause a change, and does it reverse?
Where desire changes for the better, people usually notice over weeks rather than days. If sexual function got worse rather than better after starting it, that is worth reporting — it is the less expected direction.
What should I do if I notice this while taking bupropion?
No. Never stop, pause, or reduce a prescribed medicine on your own because of a side effect — several medicines on this site are dangerous to stop suddenly, and the condition being treated does not pause while you experiment. Bring the observation to the person who prescribed it; a dose review, a different preparation, or a different approach may all be options, and only they can weigh them against what the medicine is doing for you.
What should I ask about bupropion at my appointment?
A specific question gets a better answer than a general one. For this class: Is sexual function something you can factor into which antidepressant we use? Is this suitable given the rest of my history? What should I watch for in the first few weeks?
The full class page
This page exists so a name is findable. The class page is where the detail lives.
Educational information about categories of medicine only — not medical advice, not a diagnosis, and not a statement about your prescription. It does not cover doses, interactions between medicines, or alternatives, and it cannot know what else is going on with your health. Sexual symptoms often have more than one cause at once. Pain, bleeding, or a symptom that is new and unexplained always deserves assessment.
