Medicines and sexual problems
Key points about medicines and sexual problems
- Some medicines have side effects that can cause sexual problems.
- How this affects someone will vary depending on the individual person and medicine.
- It’s only a problem if it bothers you. If you’re concerned about this issue, talk to your healthcare provider.

Medicines can cause various sexual problems for adults, including:
- A lack of sexual desire or interest in sex (low libido).
- Reduced ability to become physically aroused during sexual activity, including problems achieving and maintaining an erection (erectile dysfunction).
- Delayed or absence of orgasm (climax).
- Pain during intercourse (this mostly affects women).
- Sustained erection lasting longer than 4 hours (priapism).
The following is a list of medicines that are known to cause sexual problems for some people. It's important to note that not everyone responds in the same way to these medicines. The risk of sexual side effects is increased if you're taking more than 1 of them.
If you're taking a medicine and you're worried about its effects, don't stop taking it suddenly. Talk with your healthcare provider first. Sometimes there might be a different medicine you can take that's less likely to cause sexual problems.
Examples of medicines that are known to cause sexual problems for some people
- Antidepressants
- Antipsychotics
- High blood pressure medicines
- Some anti-seizure medicines
- Treatments for cancer
- Medicines for bladder and prostate problems
- Corticosteroids.
Alcohol and recreational drugs
Recreational drugs such as alcohol, narcotics, stimulants and hallucinogens also affect sexual function.
Short-term use of alcohol affects sexual desire, diminishes performance and can delay orgasm or ejaculation.
Drinking alcohol or using recreational drugs while taking some medicines can make sexual side effects worse.
Not all sexual problems are caused by medicines, so it isn’t always easy to know whether medicines are the cause.
Erectile dysfunction can be caused by physical and emotional factors, or a combination of both. Sexual problems may be due to relationship difficulties or other causes.
Sometimes the underlying medical condition being treated can also affect erectile function. For example, high blood pressure (hypertension), depression and psychosis are associated with sexual problems.

If you’re worried about your medicines causing sexual problems, don’t stop taking your medicine suddenly. Discuss this with your healthcare provider. Some medicines need to be stopped gradually, as sudden withdrawal can make you feel very unwell.
Sometimes a more suitable medicine can be found or your dose can be reduced.
For erectile dysfunction, your healthcare provider will consider if taking a phosphodiesterase type 5 inhibitor (such as sildenafil or tadalafil) is suitable for you. However, these medicines aren’t suitable if you have certain medical conditions or take certain medicines.
For vaginal dryness, your healthcare provider will consider if oestrogen vaginal cream is suitable for you.
