Tibolone side effects: common, rare and warning signs
Like any active medication, Tibolone (Tibolone) can produce side effects. Most are mild and transient at the standard 2.5mg dose, but a small subset are serious and call for stopping the medication and seeking medical help. This page summarises what is typical, what is rare, and what should never be ignored.
Common side effects of Tibolone
According to the prescribing information for Tibolone, the most frequent side effects are usually dose-related and resolve on their own within hours of dosing. They typically reflect the medication's mechanism: Tibolone is a prodrug; on absorption it is rapidly converted to three active metabolites (3α-OH-tibolone, 3β-OH-tibolone and Δ4-tibolone) with different tissue-selective activity. For most users on Tibolone at 2.5mg, side effects fade as the body adjusts, often within the first few weeks of regular use.
Serious or warning signs
Rare but serious adverse effects deserve immediate medical attention. These include severe allergic reactions, sudden vision or hearing changes, chest pain, prolonged or painful effects on cardiovascular tissue, severe abdominal pain or signs of bleeding. Anyone experiencing these on Tibolone should stop the medication and contact emergency services or a healthcare provider promptly.
