Diora is a combined hormonal contraceptive pill containing ethinylestradiol, a synthetic oestrogen, and levonorgestrel, a synthetic progestin. Together they suppress ovulation each cycle, thicken cervical mucus so sperm struggle to reach the uterus, and thin the uterine lining so it cannot support implantation. This three-layer mechanism makes Diora a standard combined-hormone formula used widely both in Thailand and internationally. The tablets are small, easy to swallow, and have no strong smell or taste.

Diora is used as a primary method of monthly contraception for women of reproductive age who want to prevent pregnancy. It also suits those with irregular cycles, since continuous hormone intake tends to make periods more regular and predictable. Beyond contraception, consistent use of combined hormonal pills can help reduce menstrual cramps and excessive bleeding in some users. It works well both for first-time pill users and for anyone switching from another brand containing ethinylestradiol and levonorgestrel. Anyone planning a future pregnancy can stop Diora at any time without finishing the pack, and fertility usually returns within a few cycles after stopping.

Both Diora packs are taken once daily at the same time, but they differ in the break period. The 21-tablet pack is taken for 21 consecutive days, followed by a 7-day break before starting a new pack — periods usually occur during that break. The 28-tablet pack is designed for continuous use with no break: the first 21 tablets contain hormones, while the last 7 are inactive placebo or iron tablets that help you remember to start the next pack on time. Those worried about forgetting the restart date often prefer the 28-tablet pack, while those used to counting their own break days often choose the 21-tablet pack. Both give equal contraceptive effectiveness when taken correctly.

Common side effects during the first 1-3 months of taking Diora include mild nausea, breast tenderness, headache, mood changes, and spotting between periods, which usually settle as the body adjusts to the hormone levels. If these symptoms are severe or last beyond 3 months, consult a doctor about switching formulas. Rare but urgent side effects requiring immediate medical attention include one-sided leg swelling and redness, severe chest pain, or difficulty breathing — possible signs of a blood clot.

Diora should not be used during pregnancy or suspected pregnancy, in anyone with a history of venous or arterial blood clots, severe liver disease, or hormone-sensitive cancers such as breast cancer. Smokers over 35 face a higher clot risk with combined hormonal pills and should consult a doctor first. Anyone with migraine with aura should also mention it, as it may raise stroke risk. Breastfeeding mothers within the first 6 weeks postpartum should avoid combined hormonal pills, as they may reduce milk supply.

Annylyn (Ethinylestradiol + Gestodene) uses a different progestin, gestodene instead of levonorgestrel, and is positioned as a simple, beginner-friendly option, also available in 21 and 28-tablet packs like Diora. Preme (Cyproterone Acetate + Ethinylestradiol) uses an anti-androgenic progestin, marketed mainly for reducing acne and water retention, and only comes in a continuous 28-tablet pack. In short: choose Diora for a standard levonorgestrel formula with a choice of pack format, Annylyn for a simple beginner formula, and Preme if skin and acne control matter most.

Some medicines can reduce how well Diora works, including certain anti-seizure drugs, the antibiotic rifampicin, and St. John’s Wort. Always tell your pharmacist you are taking a combined hormonal pill whenever buying other medicine. Common antibiotics such as amoxicillin do not significantly reduce pill effectiveness based on current evidence, but severe diarrhoea or vomiting alongside antibiotic use calls for backup contraception, such as condoms, during that period for extra peace of mind.

Starting Diora within the first 5 days of your cycle gives immediate contraceptive protection from the first tablet. Starting on any other day means you need backup contraception, such as condoms, for at least the first 7 days while hormone levels build up enough to fully suppress ovulation. Taking it at the same time every day matters more for effectiveness than which brand or formula is used.
