Do antibiotics delay menstruation?

Although there is speculation on the internet that antibiotics and delayed menstruation may be related, scientific studies mostly do not confirm this theory. There is little evidence to show a direct link between antibiotics and a delayed period. An exception is the drug rifampicin, which is used to treat tuberculosis and has been shown to affect menstruation.

Many women notice that their period is delayed when they take antibiotics. However, this delay is probably not caused by the antibiotics themselves, but rather by the factors that led to their use. Illnesses requiring antibiotic treatment are often accompanied by stress or a general weakening of the body. These factors can play a role in menstrual delay.

Do antibiotics affect menstruation in other ways?

Antibiotics generally do not affect the length or intensity of bleeding. So if you are wondering whether antibiotics and heavy menstruation are related, the answer is probably no.

Another interesting but little-explored question is the relationship between antibiotics and contraception. According to a 2018 article published in the American Journal of Obstetrics and Gynecology, only rifamycin, a substance found in the antibiotic rifampin, has been shown to reduce the effectiveness of hormonal contraception. Nevertheless, some doctors warn that other antibiotics may affect the absorption of hormonal contraception, so they recommend using a barrier method of contraception as a backup protection during treatment.

Are there other medications that can affect menstruation?

Yes, there are other medications that can affect the menstrual cycle. These include:

• Analgesics and antipyretics: Some pain and fever medications can affect menstruation.
• Blood thinners: These medications can cause changes in menstrual bleeding.
• Antidepressants: Some medications used to treat mental health conditions can affect the menstrual cycle.
• Epilepsy medications: Some antiepileptic drugs can affect menstruation.
• Hormone therapy: Any form of hormone therapy can affect menstruation.
• Thyroid medications: Drugs used to treat thyroid problems can affect hormonal balance and menstruation.
• Chemotherapy: Cancer treatment can have a significant impact on the menstrual cycle.

If you are taking any of these medications and notice a change in your period, consult your doctor. In some cases, the change may be a normal side effect; in others, it may indicate that the medication is not suitable for you.

What are the most common reasons for a delayed period?

There are many reasons why a period may be delayed. Sometimes the delay can be a one-time occurrence, and then it returns to normal. Even women with regular cycles can occasionally experience a slight delay. The uterus simply does not adhere to a strict calendar and is not obliged to function like clockwork every month.

More frequent changes, however, may signal a problem that should not be ignored. The main reasons for a delayed period include:

• Pregnancy: If there is a possibility that you could be pregnant, take a pregnancy test.
• Breastfeeding: After childbirth, breastfeeding mothers should expect the return of their period in a few months. Breastfeeding causes temporary amenorrhea because the hormones responsible for milk production prevent the return of ovulation.
• Stress: It is one of the most common reasons for delay. Stress can lead to changes in the part of the brain that regulates menstruation.
• Body weight: Rapid weight loss or gain can affect menstruation. Whether due to physiology and low body fat percentage or the stress that can accompany this change.
• Intense physical exercise: Professional athletes often experience missed periods. This is more common in triathletes, endurance runners, gymnasts, and other professional athletes than in women who ‘just’ regularly go to the gym.
• Vaginal infections: Vaginal infections can have various manifestations. The most common symptoms include discharge, itching, burning, and pain during intercourse. However, they can also cause a delayed period or brown discharge outside of menstruation.
• Polycystic Ovary Syndrome (PCOS): Can increase hormone levels that cause delayed or missed periods. Additionally, women with this syndrome tend to gain weight, which contributes to menstrual irregularities.
• Thyroid disease: Can cause hormonal imbalance.
• Chronic conditions: Diabetes or celiac disease can cause delayed or missed periods.
• Menopause or perimenopause: As menopause approaches, periods can become less regular. If you are under 40, missed periods can be a sign of early perimenopause.
• Serious illness: Although less common, missed periods can be a symptom of vaginal cancer or reduced ovarian function. If you are over 35 and your periods are becoming increasingly irregular, consult your gynecologist.

When should you consult a doctor?

If you notice the following symptoms, you should consult a doctor:

• Your period has stopped and you are under 45 years old.
• You have missed three periods in a row.
• You are bleeding between periods.
• You are bleeding after sex.
• You notice sudden changes in your normal menstrual cycle.
• You have reason to believe you might be pregnant.

How to address changes in the menstrual cycle

The remedy for an irregular menstrual cycle depends on the underlying cause. Some steps you can take on your own include:

• Reducing stress: Find ways to reduce stress, such as meditation, yoga, or deep breathing.
• Adequate physical activity: Maintain a balance between physical activity and rest.
• Maintaining stable body weight: Avoid rapid weight loss or gain.
• Caring for the vaginal microbiome: The health of the vaginal microbiome is crucial for maintaining a regular period. You can support it with vaginal probiotics, appropriate intimate hygiene, and a balanced diet.

If you frequently notice changes in your menstrual cycle, do not leave the situation to chance and consult a doctor.

Conclusion

Antibiotics themselves are not the cause of delayed menstruation. However, this does not mean that your period will not be delayed when you take antibiotics. The stress of illness is often enough to delay menstruation. If your period has been delayed, missed, or otherwise changed from the norm recently, it is good to consult a doctor.
