Paxil CR, containing the active ingredient paroxetine, is a widely prescribed antidepressant specifically tailored for women grappling with various mental health concerns in the United Kingdom. This controlled-release formulation offers a nuanced approach to treating psychological disorders while addressing the intricate relationship between mental well-being and sexual health.

- Obsessive-Compulsive Disorder (OCD)
- Panic Disorder
- Social Anxiety Disorder
- Generalised Anxiety Disorder (GAD)
- Post-Traumatic Stress Disorder (PTSD)
- Premenstrual Dysphoric Disorder (PMDD)
Additionally, some healthcare providers prescribe Paxil CR off-label to alleviate menopausal symptoms, particularly hot flashes.
Dosage and Administration
The controlled-release formulation of Paxil CR allows for once-daily dosing, typically administered in the morning with or without food. Dosage varies based on the condition being treated and individual patient factors:

Pregnancy and Breastfeeding Considerations
Pregnancy: Paroxetine CR may potentially affect an unborn baby. It's crucial to inform your GP or specialist if you are pregnant or planning to conceive. In the UK, the Medicines and Healthcare products Regulatory Agency (MHRA) advises against the use of paroxetine during pregnancy, particularly in the first trimester, due to a possible increased risk of congenital malformations.

Breastfeeding: Paroxetine, the active ingredient in Paroxetine CR, is known to pass into breast milk in small amounts. If you are breastfeeding or plan to breastfeed, it's essential to discuss this with your GP or specialist. They will advise you on whether continuing Paroxetine CR during breastfeeding is appropriate in your situation, considering the benefits of breastfeeding alongside your need for treatment.
If you do breastfeed whilst taking Paroxetine CR, monitor your baby closely and contact your GP, health visitor, or midwife immediately if you notice:
- Unusual sleepiness
- Increased irritability
- Difficulty feeding
- Poor weight gain
These symptoms could indicate that the medication is affecting your baby.
Your healthcare team, which may include your GP, psychiatrist, and/or a perinatal mental health specialist, will work with you to balance the potential risks and benefits of Paroxetine CR use during pregnancy and breastfeeding. They will consider your individual health needs, the severity of your condition, and potential alternative treatments.
Remember, never stop taking Paroxetine CR abruptly without consulting your healthcare provider, as this can lead to withdrawal symptoms. Any changes to your medication should be made under medical supervision.
Sexual Health and Paxil CR:
Many women experience sexual side effects when taking Paxil CR, including:
- Decreased libido
- Difficulty achieving orgasm
- Vaginal dryness
Strategies to mitigate sexual side effects include:
- Open communication with healthcare providers
- Dosage adjustments
- Timing of medication intake
- Exploration of adjunctive treatments
- Consider sex therapy or counselling
- Use of lubricants for vaginal dryness
It's crucial to contextualise these effects within the broader scope of mental health treatment. Untreated depression and anxiety can significantly impact sexual function and overall quality of life. For many women, the benefits of improved mood and reduced anxiety outweigh the potential sexual side effects.
It's worth noting that as mental health improves, some women report enhanced sexual satisfaction due to reduced anxiety and improved self-esteem.
Reporting Side Effects: In the UK, you can report side effects directly to the Medicines and Healthcare products Regulatory Agency (MHRA) through the Yellow Card Scheme. Visit https://yellowcard.mhra.gov.uk/ or search for 'MHRA Yellow Card' in the Google Play or Apple App Store.
Long-Term Effects
While Paxil CR can be effective for extended periods, it's crucial to consider the implications of long-term use:
- Tolerance: Some patients may develop tolerance over time, necessitating dosage adjustments.
- Discontinuation syndrome: Abrupt cessation can lead to withdrawal symptoms, including:
- Dizziness
- Nausea
- Electrical shock sensations
- Anxiety
- Bone health: Long-term use may be associated with an increased risk of bone fractures, particularly in older adults.
- Weight changes: Some individuals experience weight gain over extended periods of use.
- Sexual function: While sexual side effects often emerge early in treatment, they can persist with continued use.
Positive long-term effects may include:
- Sustained improvement in mood and anxiety symptoms
- Enhanced quality of life
- Reduced risk of relapse in depression and anxiety disorders
Regular follow-ups with healthcare providers are essential to monitor long-term effects and adjust treatment as needed.
The National Institute for Health and Care Excellence (NICE) recommends that antidepressant treatment should be continued for at least 6 months after remission of a depressive episode. For patients with a history of recurrent depression, treatment may need to be continued for two years or longer. Always discuss the duration of your treatment with your GP or specialist.
Drug Interactions
Paxil CR can interact with various medications, potentially altering their effectiveness or increasing the risk of side effects:
| Drug Class | Potential Interaction | Recommendation |
|---|---|---|
| MAOIs | Serious, potentially fatal interactions | Contraindicated; allow 2 weeks between stopping MAOIs and starting Paxil CR |
| NSAIDs | Increased bleeding risk | Use with caution; monitor for signs of bleeding |
| Warfarin | May enhance anticoagulant effect | Close monitoring of INR; potential dosage adjustment |
| Tamoxifen | Reduced effectiveness of tamoxifen | Consider alternative antidepressants |
| Thioridazine | Increased risk of cardiac arrhythmias | Contraindicated |
| Other SSRIs | Increased risk of serotonin syndrome | Avoid concurrent use |
| Triptans | Increased risk of serotonin syndrome | Use with caution; monitor closely |
Additional considerations:
- Alcohol: Can increase drowsiness and dizziness
- St. John's Wort: May increase risk of serotonin syndrome
- Grapefruit juice: May increase blood levels of paroxetine
It's crucial to inform healthcare providers about all medications, supplements, and herbal products being used to prevent potential interactions.
Alcohol Consumption
The NHS advises that while it's not necessarily dangerous to drink alcohol while taking antidepressants, it may make you feel drowsy and affect your coordination. It's best to avoid alcohol when first starting treatment or changing doses. If you do drink, stick to the UK's low-risk drinking guidelines: no more than 14 units of alcohol per week, spread over three or more days.

FAQs
Some patients may indeed experience weight gain with long-term use of Paxil CR. However, this doesn’t occur in everyone. We’ll monitor your weight throughout the treatment and, if necessary, adjust your diet and exercise plan accordingly.
The duration of treatment is individual. Generally, it’s recommended to continue taking the medication for at least 6-12 months after symptoms improve. We’ll regularly assess your condition and decide together on the length of therapy.
It’s best to abstain from alcohol, especially when starting treatment. Alcohol can exacerbate side effects such as drowsiness and dizziness. If you do choose to drink, do so in moderation and pay close attention to how you feel.
Some painkillers, particularly NSAIDs, may increase the risk of bleeding when taken with Paxil CR. Always consult me before taking any medicines, even over-the-counter ones. We’ll find a safe painkiller option for you.
If you miss a dose, take it as soon as you remember. However, if it’s almost time for your next dose, skip the missed one and continue with your regular schedule. Never take a double dose to make up for a missed one.
Paxil CR use during pregnancy and breastfeeding requires careful consideration. There’s a potential risk of birth defects, particularly in the first trimester, and possible withdrawal symptoms in newborns. Small amounts of the drug can pass into breast milk. It’s crucial to discuss the risks and benefits with your GP or specialist if you’re pregnant, planning to become pregnant, or breastfeeding. They may suggest alternative treatments or adjust your care plan accordingly.
The adjustment period to Paxil CR usually lasts about 2-4 weeks. During this time, you may experience side effects as your body adapts to the medication. Most side effects tend to improve or resolve within this period. However, the full therapeutic benefits may take 8-12 weeks to manifest. Keep your GP or psychiatrist informed about any persistent or troublesome side effects during this period.
Paxil CR can potentially affect cognitive functions and work performance, particularly in the initial stages of treatment. Some people may experience drowsiness, difficulty concentrating, or mild memory issues. However, these effects often improve as your body adjusts to the medication. In the long term, by effectively treating depression or anxiety, Paxil CR may actually improve cognitive function and work performance for many individuals. If you notice any significant cognitive changes, discuss them with your GP or psychiatrist. They may adjust your dosage or suggest taking the medication at a different time of day to minimise any impact on your daily activities.
