An unwanted effect occurring while a medicine is used, not necessarily proof that the medicine caused it.

Medication and sexual function
Ways prescribed, pharmacy and recreational drugs may affect desire, arousal, erection, lubrication, sensation, orgasm, ejaculation, comfort or fertility. Effects vary by medicine, dose, person and health context.
Bodies & function
In brief
Recognise possible effects while reviewing benefits, risks and alternatives safely.
A sexual change may come from a medicine, the condition being treated, another health factor or several influences together. Antidepressants, some blood-pressure medicines, hormonal treatments and other drugs are common considerations, but class-level lists cannot predict one person's response. Do not stop or alter prescribed treatment without a qualified prescriber.
One medicine, supplement, food or recreational drug changing another's effect or safety.
The illness being treated may itself affect sexual function and must remain in the assessment.
Symptoms after reducing or stopping some medicines, especially abruptly, which differ from ordinary side effects.
Possible changes
Medicines may reduce or increase desire, alter genital response, delay orgasm or ejaculation, change sensation, contribute to dryness or affect fertility. The same medicine can affect people differently.
Timing relative to starting, changing dose or adding another substance is useful evidence but does not establish causation by itself.
Review with a professional
A prescriber or pharmacist can review onset, dose, other medicines, supplements, alcohol, recreational drugs and health conditions. Bring a complete list and describe the change directly.
Options may include waiting, dose timing, a supervised adjustment, switching or treating the symptom. The benefits of the original medicine remain part of the decision.
Stopping and interactions
Abruptly stopping antidepressants, steroids, hormones or other medicines can be harmful. Follow an agreed taper where needed and seek urgent help for serious reactions.
Sexual-function medicines such as sildenafil can interact dangerously with nitrates and poppers. Unregulated online products may contain unknown ingredients or doses.
Consent and quality of life
Sexual wellbeing is a legitimate treatment outcome and should not be dismissed, but nobody should be pressured to change an effective medicine for a partner's benefit.
Partners can adapt expectations without interpreting a bodily effect as rejection. The patient decides which trade-offs matter and whether a change is distressing.
Non-graphic examples

- Reviewing erectile difficulty alongside blood-pressure treatment.
