Product Description
Evra is a combined hormonal contraceptive patch with norelgestromin and ethinylestradiol that absorb through the skin. It stops ovulation, thickens cervical mucus, and thins the womb lining, preventing pregnancy much like the pill — but with no daily tablet, just one patch a week. See more oral pill options.
- 📊 Evra has a Pearl Index of 0.90 — used correctly it prevents pregnancy up to around 99% (Drugs.com, 2024)
- 📊 In typical use, the patch is about 91-93% effective, similar to the pill, as it uses the same hormones (Planned Parenthood, 2024)
- 📊 One patch releases hormones steadily for 7 days, avoiding the missed doses that make the daily pill less effective (NHS, 2024)
- 📊 Evra may work less well in women weighing 90 kg or more, so ask a pharmacist if your weight is high (NHS, 2024)
🏭 Manufacturer: Abbott (Thailand distributor: Siam Pharmaceutical). Active: norelgestromin 6 mg + ethinylestradiol 600 mcg per patch.
⚠️ Warning: The patch contains oestrogen, so it is not for heavy smokers over 35 or those with a clot history. With a chronic condition, consult a pharmacist first.
About Evra
What is Evra?
Evra is a combined hormonal contraceptive patch — a thin, beige patch worn on the skin, 3 patches per box for one cycle. The active ingredients are norelgestromin 6 mg and ethinylestradiol 600 mcg per patch.
How it works: The contraceptive patch releases hormones steadily through the skin into the bloodstream. The two hormones work in three ways: they stop ovulation, thicken cervical mucus so sperm cannot pass easily, and thin the womb lining.
Because Evra uses the same group of hormones as the pill, its contraceptive effectiveness is similar. The difference is that the patch is not taken daily — you simply change it once a week — making it suitable for people who tend to forget pills.
What is Evra Used For — Who Is It Suitable For?
Evra is used mainly for contraception. It suits women of reproductive age who want a combined hormonal method but find a daily pill inconvenient.
- People who forget pills: the patch is changed weekly, lowering the chance of missing a dose
- People who feel nauseous on pills: hormones absorb through the skin, bypassing the stomach and liver
- Busy or frequent travellers: no pill strip to carry or take at the same time daily
Besides contraception, the combined hormones may help make periods more regular. However, women weighing 90 kg or more, heavy smokers over 35, or those with a clot history should consult a pharmacist before choosing Evra.
How and Where to Apply Evra
To make the contraceptive patch Evra work, apply it to the right place at the right time:
Where to apply: Choose dry, clean, smooth skin. Recommended sites are the buttock, abdomen, upper outer arm, or upper back. Never apply on the breasts or on red, irritated, or broken skin, and do not place a new patch on the exact same spot twice in a row.
How to apply and the schedule:
- Pick a weekly "Patch Change Day", e.g. every Sunday
- Weeks 1-3: apply one new patch each week (3 patches total)
- Week 4: remove the patch and have one patch-free week — your period usually comes now
- After the patch-free week, start a new box on the same Change Day
Before applying, do not use cream, lotion, or powder on the area. Press the patch firmly for about 10 seconds, especially the edges. The patch-free interval must not exceed 7 days, otherwise use backup contraception such as condoms.
Evra Side Effects
The Evra contraceptive patch is generally well tolerated, but some people may have side effects, especially in the first 1-3 months as the body adjusts:
Common (usually settle):
- Irritation or itching at the patch site
- Breast tenderness, headache, nausea
- Spotting or breakthrough bleeding between cycles
- Mood changes or slight weight change
Seek medical care:
- Calf pain or one-sided leg swelling, chest pain, or difficulty breathing (signs of a blood clot)
- Unusually severe headache or vision changes
Allergic reaction — remove the patch and stop immediately:
- Hives, swelling of the face, lips, or tongue, or trouble breathing
Contraindications and Precautions
Contraindications:
- History of blood clots in the leg or lung, or previous stroke/heart attack
- Heavy smoking and over 35 — greatly raises clot risk
- Breast cancer or other hormone-sensitive cancer
- Severe liver disease or migraine with aura
- Suspected pregnancy
Precautions:
- Weighing 90 kg or more: the patch may work less well — ask a pharmacist
- High blood pressure, diabetes, high cholesterol: use under guidance
- Breastfeeding: oestrogen may reduce milk supply — consult a doctor
- Avoid prolonged heat or strong sun over the patch area
Evra Patch vs the Contraceptive Pill
Both the contraceptive patch and the pill are combined hormonal methods with similar effectiveness; they differ in how they are used and convenience. Here is how Evra compares with pills in our store:
- Evra (patch): one patch a week, no daily tablet, ideal if you forget pills
- Mercilon — low-dose, gentle daily pill
- Yaz — 24+4 pill that also helps acne and PMS
- Marvelon — popular, budget-friendly combined pill
In short: If you often forget pills or feel nauseous on them, the Evra patch suits you because you only change it weekly. If a daily pill is fine and you want a lower price or specific formula (e.g. for acne), an oral pill works well.
If the Evra Patch Comes Off or You Forget to Change It
The patch is designed to stay on through showering or exercise, but if it falls off or you forget to change it:
If the patch comes off:
- Off under 24 hours: re-apply if still sticky, or apply a new one now; keep the same Change Day, no backup needed
- Off over 24 hours or unsure: start a new cycle as Day 1 and use condoms for 7 days
If you forget to change it:
- Forgot at the start (week 1): apply when you remember, set a new Change Day, use backup for 7 days
- Forgot mid-cycle (weeks 2-3) by up to 48 hours: apply a new patch now, same Change Day
- Forgot by more than 48 hours: start a new cycle and use backup for 7 days
If you had sex during a gap in cover, ask a pharmacist about emergency contraception.
When to Start Evra and How Soon It Works
Starting the Evra patch at the right time helps it protect you promptly:
- Start on day 1 of your period: apply the first patch on cycle day 1 for immediate protection — no backup needed
- Start another day (day 2-5 or later): protection begins after 7 continuous days of wear; use condoms meanwhile
- Switching from the pill: start the patch per a pharmacist's advice to keep hormones continuous
Once in the rhythm of 3 weeks on + 1 week off, the patch keeps protecting you as long as you change it on time, including during the patch-free week. If unsure about starting, ask a pharmacist.

Frequently Asked Questions
The Evra contraceptive patch comes as 3 patches per box, enough for one cycle. The price at Intimo Life is affordable given the convenience of not taking a daily pill. You can see the latest price and order online on the product page, with discreet delivery across Thailand.
Yes. The contraceptive patch is designed to be water-resistant and stay on, so you can shower, swim, use a sauna, or exercise as normal. Press the edges firmly when applying and avoid scrubbing soap or heavy lotion on the area. Check daily and replace the patch if more than half lifts off.
Weight change is a side effect some people notice with hormonal contraception, but most studies do not show the patch clearly causes weight gain. Some feel slight water retention early on that settles. If you are concerned, manage diet and exercise alongside, and ask a pharmacist if your weight changes a lot.
The combined hormones in the patch may improve hormone-related acne in some people and make periods more regular, but Evra is not a dedicated acne treatment. If you want contraception and acne care together, some pills such as Yaz are designed for that. Consult a pharmacist to choose what suits your skin and health.
The Evra patch contains oestrogen, which can reduce milk supply, so it is generally not recommended in early breastfeeding. Breastfeeding mothers who want contraception should consult a doctor or pharmacist, as a progestogen-only method may be more suitable.
Mild itching or redness at the patch site is common and usually settles. Rotate the site each week to let the skin rest. If irritation is severe, the rash spreads, or it stings, remove the patch and consult a pharmacist. Do not apply over still-red or broken skin. If you have reacted to plasters or patches before, tell a pharmacist first.
The Evra patch is a small, thin, beige patch. Worn under clothing — on the buttock, abdomen, or upper back — it is usually not obvious. For a smooth look, choose a spot where clothing does not rub much. After removal there may be slight adhesive residue, which baby oil or lotion can wipe away.
After 3 weeks of wearing the patch, in the 4th patch-free week, a withdrawal bleed (period-like bleeding) usually occurs. Some people have spotting between cycles in the first 1-3 months while adjusting, which usually settles. If your period is missing and you suspect pregnancy, take a test and consult a pharmacist.
