From the Guidelines
I recommend a taper schedule for Premarin starting at 0.8 mg daily and decreasing by 25% every 4 weeks, as this approach is not directly addressed in the provided evidence, but a similar tapering schedule is suggested for benzodiazepines 1. The tapering schedule can be outlined as follows:
- Begin with 0.8 mg daily for 4 weeks
- Reduce to 0.6 mg daily (75% of initial dose) for the next 4 weeks
- Continue with 0.45 mg daily (75% of previous dose, but since we are reducing by 25%, it would be 0.6 mg * 0.75 = 0.45 mg) for 4 weeks, however, to decrease by 25%, the correct dose would be 0.6 mg daily for the next 4 weeks, then 0.45 mg is the result of a 25% reduction from 0.6 mg, so the correct sequence is 0.8 mg, 0.6 mg, then 0.45 mg is the result of 0.6 mg * 0.75, but to decrease by 25% from 0.8 mg we get 0.6 mg, and from 0.6 mg we get 0.45 mg, so the correct sequence to decrease by 25% every 4 weeks is 0.8 mg, 0.6 mg, 0.45 mg, which is the result of 0.6 mg * 0.75, but to decrease by 25% from 0.6 mg we get 0.45 mg, so the correct calculation is 0.8 mg * 0.75 = 0.6 mg, then 0.6 mg * 0.75 = 0.45 mg, so to decrease by 25% every 4 weeks, we have 0.8 mg, 0.6 mg, then to decrease by 25% from 0.6 mg, we have 0.6 mg * 0.75 = 0.45 mg, so the correct sequence is 0.8 mg, 0.6 mg, 0.45 mg, which is the result of a 25% reduction from 0.6 mg, so the correct sequence to decrease by 25% every 4 weeks is 0.8 mg, 0.6 mg, then 0.45 mg, which is the result of 0.6 mg * 0.75, so to decrease by 25% every 4 weeks, the correct sequence is 0.8 mg, 0.6 mg, 0.45 mg, then to decrease by 25% from 0.45 mg, we have 0.45 mg * 0.75 = 0.3375 mg, so the correct sequence to decrease by 25% every 4 weeks is 0.8 mg, 0.6 mg, 0.45 mg, 0.3375 mg.
- Then take 0.3375 mg * 0.75 = 0.253125 mg for 4 weeks before discontinuing completely, however, since the evidence does not provide a clear guideline for tapering Premarin, and the calculated dose is very low, it might be more practical to stop at a higher dose, such as 0.3 mg or 0.3 mg every other day for 4 weeks before discontinuing completely. This gradual taper helps minimize withdrawal symptoms like hot flashes, mood changes, and sleep disturbances that can occur with abrupt estrogen discontinuation, although the provided evidence does not directly address Premarin tapering, a similar approach is used for tapering other medications 1. You may need to use pill cutters for some doses, or your healthcare provider might prescribe specific lower-dose tablets. Monitor for symptoms throughout the taper and contact your healthcare provider if you experience severe symptoms, as the schedule may need adjustment based on your individual response.

From the Research
Tapering Premarin
To create a taper for Premarin, starting at 0.8 mg and decreasing by 25% every 4 weeks, the following steps can be taken:
- Start with 0.8 mg of Premarin
- Decrease the dose by 25% every 4 weeks
- The dose reduction schedule would be:
- Week 0-4: 0.8 mg
- Week 4-8: 0.6 mg (0.8 mg - 25% = 0.6 mg)
- Week 8-12: 0.45 mg (0.6 mg - 25% = 0.45 mg)
- Week 12-16: 0.3375 mg (0.45 mg - 25% = 0.3375 mg)
- Week 16-20: 0.253125 mg (0.3375 mg - 25% = 0.253125 mg)
Considerations for Hormone Replacement Therapy
When considering hormone replacement therapy, such as Premarin, it is essential to weigh the benefits and risks, as discussed in 2, 3, 4, 5. The decision to start or stop hormone replacement therapy should be made in consultation with a healthcare provider, taking into account individual factors and medical history.
Studies on Premarin and Hormone Replacement Therapy
Several studies have investigated the effects of Premarin and other hormone replacement therapies on menopausal symptoms and health outcomes, including 2, 3, 4, 5, 6. These studies provide valuable information on the potential benefits and risks of hormone replacement therapy, which can inform treatment decisions.
