Are there any contraindications for levonorgestrel tablets

During the use of levonorgestrel tablets, strict dietary restrictions are usually not necessary, but alcohol consumption, excessive caffeine intake, and high-fat diet should be avoided. Levonorgestrel tablets are an emergency contraceptive pill mainly composed of progesterone, and their absorption may be affected by factors such as diet and gastrointestinal status.

1. Avoid drinking alcohol

Alcohol may increase the metabolic burden of drugs on the liver and affect the stability of drug efficacy. Levonorgestrel tablets themselves need to be metabolized through the liver, and drinking alcohol may interfere with the drug breakdown process, reducing the success rate of contraception. Alcohol should be prohibited within 48 hours after taking medication, and individuals with special physical conditions should be more cautious.

2. Limit Caffeine

Excessive intake of caffeinated beverages such as coffee and strong tea may exacerbate adverse reactions such as nausea and dizziness caused by medication. Caffeine can stimulate the central nervous system and, when combined with progesterone, may cause palpitations or insomnia. It is recommended to control caffeine intake within 24 hours after taking medication. 3. Reduce high-fat diet. High fat foods may slow down the absorption rate of drugs in the gastrointestinal tract and affect the peak time of blood drug concentration. Levonorgestrel tablets should reach an effective concentration within a specific period of time, and oily foods such as fried foods and fatty meat should be avoided for 2 hours before and after taking the medication.

4. Pay attention to drug interactions

Some antibiotics, antiepileptic drugs, and Chinese herbal medicines may reduce the effectiveness of levonorgestrel. Factors such as rifampicin and St. John's wort can induce hepatic enzyme activity and accelerate drug metabolism. Long term use of other medications should be consulted with a doctor before using emergency contraception.

5. Caution should be exercised for special constitutions

Lactose intolerant individuals should be aware that the drug contains lactose components, and allergic individuals should confirm the safety of excipients. Some people may experience gastrointestinal discomfort after taking medication. It is recommended to have a light diet and drink small amounts of water in moderation to alleviate symptoms.

After taking levonorgestrel tablets, one should maintain a regular daily routine and avoid vigorous exercise or overwork. If there is persistent vomiting or abnormal bleeding, seek medical attention promptly. Daily supplementation of vitamin B and iron can be achieved through a balanced diet, but it should be taken at least 2 hours apart from the time of medication. Emergency contraceptive pills cannot replace conventional contraceptive measures and should not be used more than three times within a year.
