Side Effects of Hormonal Medications in Women's Health

Drug side effects

Hello doctor, my period was 15 days late, so I visited a doctor on March 10.
Due to the pandemic, I didn't want to go to a distant obstetrics and gynecology clinic, so I went to a family medicine clinic near my home.
The doctor had me take a pregnancy test, which confirmed that I was not pregnant, so he prescribed me medication to induce my period (Premarin 0.625 mg and Norcolut 5 mg) for five days.
On the morning of the third day, I woke up feeling dizzy for a moment, but it passed quickly, so I didn't think much of it and continued taking the medication as prescribed.
However, on the fourth day, I started feeling intense dizziness, weakness, and nausea.
I called the family medicine doctor to ask if I could stop taking the remaining medication, but the doctor advised me to finish it, stating that it was a side effect.
I completed the medication...
The day after finishing the medication, I still experienced significant dizziness and a persistent feeling of weakness until the fifth day, when my period finally started...
but the dizziness sensation remained, and I felt heavy in my body.
Today, the dizziness is not as severe, but I still feel heavy...
Could you please explain why this is happening? Is it related to progesterone, or am I just feeling weak?

More Info

The experience you've described regarding the side effects of hormonal medications, particularly the use of Premarin (conjugated estrogens) and Norcolut (norethisterone), is not uncommon. Hormonal treatments can lead to a variety of side effects due to their impact on the body's hormonal balance. Let's break down the potential reasons for your symptoms and provide some insights into the effects of these medications on women's health.

Understanding Hormonal Medications
1. Premarin: This medication is primarily used to treat symptoms of menopause and to regulate menstrual cycles. It contains estrogen, which can influence various bodily functions. Common side effects include headaches, nausea, dizziness, and mood changes. Estrogen can also cause fluid retention, which may contribute to feelings of heaviness or lethargy.

2. Norcolut: This is a synthetic progestin that is often used to regulate menstrual cycles and treat conditions like endometriosis. Side effects can include nausea, headaches, breast tenderness, and mood swings. Progestins can also lead to changes in mood and energy levels, which might explain your feelings of dizziness and fatigue.

Your Symptoms
- Dizziness and Nausea: The dizziness you experienced could be attributed to the hormonal fluctuations caused by these medications. Both estrogen and progestin can affect blood pressure and circulation, leading to feelings of lightheadedness or dizziness. Additionally, nausea is a common side effect of hormonal treatments, particularly in the early stages of use.

- Fatigue and Weakness: Feeling weak or fatigued can be a result of hormonal changes, especially if your body is adjusting to the introduction of these medications. Hormonal treatments can also affect your metabolism and energy levels, leading to feelings of lethargy.

- Delayed Menstruation: It’s important to note that hormonal medications can sometimes cause a delay in menstruation before they induce a period. This is because they work to regulate the hormonal signals that control your menstrual cycle.

Should You Be Concerned?
While the symptoms you experienced can be distressing, they are often temporary and may subside as your body adjusts to the medications. However, if the dizziness and feelings of weakness persist, or if you experience any severe side effects (such as severe headaches, vision changes, or chest pain), it is crucial to seek medical attention promptly.

Hormonal Balance and Health
Long-term use of hormonal medications can have various effects on women's health. For instance, while they can help regulate menstrual cycles and alleviate symptoms of conditions like endometriosis, they may also carry risks such as increased chances of blood clots, especially in women who smoke or have other risk factors.

Recommendations
1. Monitor Your Symptoms: Keep track of how you feel over the next few days. If symptoms improve, it may indicate that your body is adjusting to the medication.

2. Consult Your Doctor: If dizziness and fatigue continue, or if you have concerns about the medications, it’s advisable to consult with your healthcare provider. They may consider adjusting your dosage or switching medications.

3. Lifestyle Considerations: Ensure you are staying hydrated, eating a balanced diet, and getting enough rest. These factors can significantly influence how your body responds to hormonal treatments.

4. Follow-Up: Regular follow-ups with your healthcare provider are essential to monitor your health and the effects of any medications you are taking.

In conclusion, while hormonal medications can be effective in managing menstrual irregularities and other health issues, they can also lead to side effects that require careful monitoring. Always communicate openly with your healthcare provider about any concerns or symptoms you experience while on these medications.
