Period delay tablets are a safe and effective way for many women to postpone their period for holidays, special events, or other personal reasons. They are a trusted method of reproductive health control, allowing women to temporarily adjust their menstrual cycle with minimal side effects.
At onlinemeds, we provide safe and regulated access to period delay tablets, ensuring peace of mind when you need them. However, while these medications are generally safe, they are not suitable for everyone. Certain medical conditions or health risks may make them unsuitable or require additional medical advice before use.
This guide will explain who shouldn’t take period delay tablets, potential risks, and how to use them safely.
How Do Period Delay Tablets Work?
Period delay tablets, such as norethisterone, work by temporarily maintaining high levels of progesterone in the body. This stops the lining of the uterus from shedding, effectively delaying your period until you stop taking the medication.
They are usually taken three days before your period is due and can delay menstruation for up to 17 days. Once you stop taking them, your period should return within two to three days.
For most women, period delay tablets are a safe and effective option, but they may not be suitable for those with certain health conditions.
Who Shouldn’t Delay Their Period?
While most women can take period delay tablets safely, there are some groups who should avoid them or consult a doctor before use.
1. Women with a History of Blood Clots (Deep Vein Thrombosis or Pulmonary Embolism)
Period delay tablets contain progestogen, a hormone that may slightly increase the risk of blood clots. If you have a personal or family history of deep vein thrombosis (DVT), pulmonary embolism (PE), or thrombophilia, you should not take period delay tablets without consulting a doctor first.
2. Women with Uncontrolled High Blood Pressure
High blood pressure (hypertension) increases the risk of cardiovascular complications, and some hormone-based medications can contribute to further increases in blood pressure. If you have poorly controlled or severe hypertension, period delay tablets may not be suitable for you.
3. Women with a History of Hormone-Sensitive Cancers
If you have had breast cancer, ovarian cancer, or other hormone-sensitive cancers, you should avoid period delay tablets. These cancers can be influenced by hormonal changes, and using additional progestogen may not be safe.
4. Women with Liver Disease
The liver helps metabolise hormones, including the progestogen in period delay tablets. If you have liver disease or a history of liver tumours, your body may struggle to process the medication properly, increasing the risk of side effects.
5. Women with Unexplained Vaginal Bleeding
If you are experiencing irregular bleeding or spotting between periods and the cause is unknown, you should not take period delay tablets without speaking to a doctor first. This could be a sign of an underlying issue that needs medical attention.
6. Women Who Are Pregnant or Suspect They May Be Pregnant
Period delay tablets are not a contraceptive and should not be taken if you are pregnant or think you might be pregnant. They will not stop pregnancy and are not designed for use during pregnancy.
7. Women with Severe Migraines (With Aura)
If you experience migraines with aura, taking hormone-based medications like period delay tablets may slightly increase the risk of stroke. Women with severe migraine conditions should speak to a doctor first before using these tablets.
Are Period Delay Tablets Safe for Most Women?
For the majority of women, period delay tablets are a safe and convenient option to postpone their period without long-term effects on fertility or health. They are widely used and trusted in reproductive health management.
However, if you have any underlying medical conditions, it’s best to check with a doctor or pharmacist before taking them. At onlinemeds, we offer a safe and regulated service, ensuring that all patients receive appropriate advice and medication based on their health history.
Possible Side Effects
Most women experience little to no side effects, but some may have mild reactions, including:
–> Nausea or bloating
–> Breast tenderness
–> Mild headaches
–> Changes in mood
–> Spotting or irregular bleeding after stopping the medication
These symptoms usually resolve once the medication is stopped, and your next period should return to normal. If side effects persist, consult a healthcare professional.
