HRT
HRT Side Effects and Review
Common side effects of HRT, when they warrant review, and why structured follow-up matters as much as the initial prescription.
Some women begin HRT and notice a clear improvement within weeks. Others find the picture less straightforward. Side effects may emerge, bleeding patterns may change, mood may be unpredictable, or the original symptoms may not have fully resolved. This does not necessarily mean that HRT is unsuitable. It more often means that the treatment needs reviewing — the dose may need adjusting, the formulation may need changing, or the progestogen component may need reassessing.
The difficulty is that many women are started on HRT without a clear plan for follow-up, or they are told to wait several months before seeking review. Structured follow-up should be part of any HRT prescription, not an afterthought. If you are considering HRT for the first time, start with menopause and HRT.

Common side effects in the first few months
Some side effects are common when starting HRT and often settle within the first three months as the body adjusts. These include breast tenderness, bloating, headaches, nausea, irregular bleeding or spotting, and mood fluctuation. Skin irritation can occur with transdermal patches. These are generally not reasons to stop treatment immediately, but they should be monitored and discussed at follow-up. If side effects persist beyond three months or are significantly affecting quality of life, review is warranted rather than waiting longer.
When side effects warrant clinical review
Review is clinically appropriate when side effects have not settled after three months, when bleeding is heavy, prolonged, or has restarted after a period of absence, when mood has worsened rather than improved, when the original symptoms have not responded, or when new symptoms have appeared that were not present before treatment. In many cases the solution is a dose adjustment, a change in the oestrogen delivery method (for example, switching from tablets to patches or gel), or a change in the progestogen component. Stopping HRT entirely is sometimes appropriate, but it should be a considered clinical decision rather than a reaction to manageable early side effects.
Structured review
What an HRT review covers
A structured review assesses whether the original symptoms have improved, whether side effects are settling or persisting, whether bleeding patterns have changed, whether the current preparation and dose remain appropriate, whether other symptoms need addressing, and whether any adjustment to the treatment plan would be beneficial. This is a clinical conversation, not a box-ticking exercise.
Depending on the situation, the review may also consider whether blood tests would be useful, whether a different delivery method should be tried, or whether specialist referral is appropriate.

Why follow-up matters as much as the initial prescription
HRT is not a fixed prescription. The dose and preparation that suit a woman at the start of treatment may not remain optimal over time. Symptoms may evolve, risk factors may change, new treatments may become available, and the balance between benefit and side effects may shift. Regular review ensures that treatment continues to match the clinical picture rather than continuing on autopilot. At Basuto, menopause care includes structured follow-up as standard, with prescription adjustments made as part of ongoing clinical management.
Ongoing care
Transferring HRT care to Basuto
Some patients come to Basuto because they were started on HRT elsewhere and want more structured follow-up. Others want a second opinion on whether their current treatment remains appropriate. A review appointment gives time to assess the current prescription, discuss any concerns, and establish an ongoing care plan with a GP who has time to explain things properly.
An online appointment may be suitable for straightforward HRT reviews where no examination is needed.
Frequently asked questions
How long should I wait before expecting side effects to settle?
Most common side effects — breast tenderness, bloating, spotting, headaches — typically settle within three months. If they persist beyond this, or if they are significantly affecting your quality of life, review is appropriate. You do not need to endure months of discomfort without clinical input.
Is bleeding on HRT normal?
Some bleeding or spotting is common in the first three to six months, particularly with sequential (cyclical) HRT. Unexpected bleeding on continuous combined HRT, heavy bleeding, or bleeding that restarts after it has stopped should be reviewed. Your GP can assess whether the bleeding pattern is expected or whether investigation is needed.
Can I switch to a different type of HRT?
Yes. Switching between preparations — for example, from oral to transdermal, or from one progestogen to another — is common and can resolve side effects that are related to the specific formulation rather than to HRT as a concept. A menopause review can help determine whether a change would be beneficial.
