Livial Side Effects: Complete Safety Guide

Common Side Effects of Livial

Like all HRT products, Livial can cause side effects. Most are mild and tend to occur during the first few months of treatment as your body adjusts. The frequency categories below are based on clinical trial data and the Summary of Product Characteristics.

Very common (may affect more than 1 in 10 women)

• Breast pain or tenderness – often improves within 3–6 months.
• Stomach or pelvic pain – usually mild and transient.

Common (may affect up to 1 in 10 women)

• Vaginal bleeding or spotting – most common in the first 3–6 months. If it continues beyond 6 months or starts later, see your doctor.
• Unusual hair growth (hirsutism) – due to the androgenic activity of the Δ4‑isomer.
• Vaginal discharge, itching, or thrush – usually mild and manageable.
• Thickening of the womb lining or cervix – requires monitoring.
• Weight gain – usually modest (1–2 kg) and stabilises with continued use.

Uncommon (may affect up to 1 in 100 women)

• Swollen hands, ankles, or feet (fluid retention)
• Stomach upset, nausea
• Acne
• Painful nipples
• Vaginal infections

Rare (may affect up to 1 in 1000 women)

• Itchy skin (pruritus)
• Depression, dizziness, headache
• Joint or muscle pain
• Skin rash, vision changes, changes in liver function tests

Serious Side Effects: When to Stop and Seek Help

Livial, like other HRT preparations, carries risks of serious adverse events. While these are rare, they require immediate medical attention. The following risks are increased in women taking Livial:

Breast Cancer

Tibolone increases the risk of breast cancer. The extra risk is similar to that seen with combined HRT. The risk increases with duration of use and returns to baseline after stopping. For women in their 50s, over 5 years, approximately 4–7 in 1000 non‑users develop breast cancer; with HRT (including Livial) this rises to 9–12 in 1000.

Endometrial Cancer

Livial does not stimulate the endometrium, so the risk of endometrial cancer is not increased compared to oestrogen‑only HRT. However, any unexpected bleeding after the first 6 months of use should be investigated.

Blood Clots (Venous Thromboembolism)

The risk of deep vein thrombosis (DVT) or pulmonary embolism is increased with Livial, though the risk is lower than with oestrogen‑progestogen HRT. If you develop painful leg swelling, sudden chest pain, or difficulty breathing, seek emergency help.

Stroke and Heart Disease

Livial slightly increases the risk of stroke, especially in women over 60. The risk of heart attack is not significantly increased in healthy women near menopause but rises with age. If you experience sudden numbness, severe headache, or chest pain, seek urgent care.

Gallbladder Disease

HRT, including tibolone, may increase the risk of gallstones and gallbladder disease.

When Do Livial Side Effects Start?

The timing of side effects depends on the type of reaction:

• Immediate (first days to weeks): Mild side effects such as breast tenderness, nausea, headache, or fluid retention often appear within the first few days to weeks of starting Livial. These are usually due to the hormonal adjustment and often resolve spontaneously.
• First 3–6 months: Irregular bleeding or spotting is most common during this period. It occurs because the endometrium is adapting to the progestogenic effect of the Δ4‑isomer. Up to 40% of women may experience some spotting in the first 3 months.
• Long‑term (after 1–2 years): Risks such as breast cancer, blood clots, and stroke are cumulative and increase with longer duration of use. These do not have an acute onset but develop over time.

If any side effect appears suddenly after you have been stable on Livial for many months, it may indicate a new condition – always report it to your doctor.

How Long Do Livial Side Effects Last?

The duration of side effects varies:

• Transient side effects: Breast pain, nausea, headache, and fluid retention usually improve within 3–6 months as the body acclimatises to the hormonal environment. If they persist beyond 6 months, discuss alternative options with your doctor.
• Bleeding/spotting: Most women experience some bleeding or spotting only during the first 3–6 months. If bleeding continues beyond 6 months, stops and then restarts, or occurs after you stop Livial, it requires investigation.
• Serious risks: If a serious adverse event such as a blood clot or stroke occurs, the effects may be permanent. Treatment is stopped immediately, and the underlying condition is managed separately.
• After stopping Livial: Most side effects resolve within a few weeks to months after discontinuation. The risk of breast cancer decreases after stopping, returning to baseline after about 5–10 years (similar to other HRT).

Livial Contraindications: Who Should Not Take Livial

Livial is not suitable for everyone. Do not take Livial if any of the following apply to you. If you are unsure, ask your doctor.

• You have or have ever had breast cancer, or are suspected of having it.
• You have cancer sensitive to oestrogens (e.g., endometrial cancer).
• You have unexplained vaginal bleeding that has not been investigated.
• You have excessive thickening of the womb lining (endometrial hyperplasia) that is not being treated.
• You have or have ever had a blood clot in a vein (deep vein thrombosis, pulmonary embolism).
• You have a blood clotting disorder (e.g., protein C, protein S, antithrombin deficiency).
• You have or recently have had a heart attack, stroke, or angina.
• You have or have ever had liver disease and liver function tests have not returned to normal.
• You have a rare inherited blood disorder called porphyria.
• You are allergic to tibolone or any of the other ingredients (lactose, potato starch, etc.).
• You are pregnant or think you might be pregnant, or you are breastfeeding.

Additionally, you should not start Livial until at least 12 months after your last natural period. If you have a premature menopause (due to surgery or ovarian failure), your doctor will advise on the appropriate timing.

Food and Drug Interactions with Livial

Certain medications and herbal products can affect how Livial works, potentially reducing its effectiveness or increasing side effects.

Medicines that interact with Livial

• Warfarin and other anticoagulants – Livial may alter the anticoagulant effect; close monitoring of INR is needed.
• Antiepileptics – phenytoin, carbamazepine, phenobarbital – these induce liver enzymes and can accelerate the metabolism of Livial, reducing its effectiveness.
• Rifampicin (tuberculosis treatment) – also a potent enzyme inducer that may lower Livial levels.
• St John’s Wort (Hypericum perforatum) – a herbal remedy that induces CYP3A4 and can significantly reduce tibolone exposure.

Food interactions

There are no specific foods that must be avoided with Livial. However, avoid grapefruit juice if you are sensitive to CYP3A4 interactions, as it may modestly increase tibolone levels. Alcohol does not directly interact but excessive alcohol consumption is a risk factor for breast cancer and should be minimised.
