Levonelle One Step

Levonorgestrel, the active ingredient in Levonelle One Step, is a progestin presented as a 1.5 mg oral tablet for oral use. It provides emergency contraception by preventing pregnancy after unprotected intercourse or contraceptive failure. It works when taken within a defined time window after the event.

Levonorgestrel is used as an emergency contraceptive to prevent pregnancy after unprotected sexual intercourse.

- Unprotected intercourse: reduces the risk of pregnancy when administered promptly after the event. - Contraceptive failure: offers a backup method following missed hormonal dose or condom break. - Delayed ovulation: inhibits or delays ovulation to prevent fertilization. - Prevention of implantation: may alter the endometrial lining to reduce the chance of implantation. - Post‑coital contraception: provides an effective option within 72 hours after intercourse.

Levonorgestrel may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects: - Nausea: mild stomach upset that usually resolves without treatment. - Headache: transient headache that may be relieved with over‑the‑counter analgesics. - Fatigue: temporary feeling of tiredness or low energy. - Abdominal pain: mild cramps or discomfort in the lower abdomen. - Menstrual changes: spotting, earlier or later onset of the next period.

Serious or Rare Side Effects: - Allergic reaction: rash, itching, swelling of face or throat requiring medical attention. - Severe abdominal pain or persistent vomiting: may indicate a more serious condition and should be evaluated. - Unusual vaginal bleeding: heavy or prolonged bleeding that is not typical for the menstrual cycle.

When using Levonelle One Step, certain precautions help ensure safety and effectiveness.

- Timing of administration: take as soon as possible after unprotected intercourse, preferably within 72 hours. - Contraindications: avoid if you have a known hypersensitivity to levonorgestrel or any tablet excipients. - Pregnancy status: not intended for use if you are already pregnant; a pregnancy test is not required before taking the tablet. - Breastfeeding: consult a healthcare professional, as limited data are available on exposure through breast milk. - Drug interactions: review concomitant medications that may reduce levonorgestrel efficacy, such as certain antibiotics or anticonvulsants. - Store at ambient temperature: keep below 25 °C, retain in the original packaging, and protect from moisture.

Levonelle One Step may interact with other medicines, affecting its effectiveness or safety.

Major Interactions (Avoid): - Rifampicin and other enzyme‑inducing antibiotics: these agents can markedly lower levonorgestrel plasma concentrations, reducing contraceptive efficacy. - Antiepileptic drugs (phenytoin, carbamazepine, phenobarbital): enzyme induction by these medicines may diminish the effectiveness of emergency contraception. - St. John’s wort: this herbal supplement induces hepatic enzymes and can decrease levonorgestrel activity.

Moderate Interactions (Monitor Closely): - Hormonal contraceptives taken concurrently: combined use may lead to reduced overall contraceptive protection, so additional precautions are advised. - Antifungal azoles (ketoconazole, itraconazole): these can increase levonorgestrel levels, potentially heightening side‑effect risk. - Antiretroviral efavirenz: may lower levonorgestrel effectiveness, requiring consideration of alternative emergency contraception.
