Dydrogesterone is a synthetic hormone that mimics natural progesterone. Doctors prescribe it for menstrual problems, infertility, and to support early pregnancy. Because it’s a lab‑made version, it’s more predictable than the body’s own hormone, which makes dosing easier.
If you’ve been told to start dydrogesterone, you’ll usually take a tablet once or twice a day. The exact amount depends on why you’re using it – for example, a typical dose for luteal‑phase support is 10 mg daily, while treating heavy periods might require 20 mg split into two doses. Always follow your doctor’s instructions; jumping to a higher dose without advice can cause unwanted symptoms.
Most people use dydrogesterone for three reasons: to regularise a shaky menstrual cycle, to help the uterine lining stay ready for a fertilised egg, and to reduce the risk of miscarriage in early pregnancy. For irregular periods, doctors often start with 10 mg a day for 10‑14 days, then pause and repeat the cycle. When it’s given after IVF, the medication may be taken from day 2 or 3 of the cycle until the pregnancy test.
Because dydrogesterone is absorbed well, you’ll notice its effect within a few days. If you miss a dose, take it as soon as you remember – unless it’s almost time for the next one, then just skip the missed pill. Don’t double up; that can increase the chance of nausea or breast tenderness.
Side effects are usually mild. Some people get a bit of nausea, a headache, or feel more tired than usual. Rarely, you might see mood swings or spotting between periods. If any reaction feels severe – like sudden swelling, severe rash, or trouble breathing – get medical help right away.
Before you start, tell your doctor about any other meds you’re on, especially blood thinners or hormonal birth control. Dydrogesterone can interact with certain antibiotics and anti‑epileptic drugs, changing how well it works.
When you look to buy dydrogesterone online, stick to pharmacies that require a prescription and show clear contact details. Check for a UK‑based licence number or a CIPA verification badge – those are good signs the site is legit. Compare prices, but don’t pick the cheapest option if the site looks sketchy. A reputable pharmacy will also give you a clear shipping timeline and a way to track your order.
Finally, keep your medication in a cool, dry place and check the expiry date before using. If you’re unsure about any step – dosage, side effects, or where to order – ask a pharmacist or your doctor. They can clear up doubts and make sure you get the right treatment without extra hassle.
