How To Use Oestrogel

How To Take: Step‑by‑Step Usage Guide

Follow these steps precisely to ensure consistent absorption and safety:

1. Prepare the pump (first use only): Remove the cap, detach the stopper from the spout, and press the plunger down a few times until gel appears. Discard this first dose – it primes the pump.
2. Wash hands and application area: Ensure skin is clean, dry, and free from cuts or irritation. Do not use strong skin cleansers or detergents beforehand.
3. Dispense the gel: Hold the pump with one hand, place the other hand under the spout, and push the plunger down firmly. One pump delivers 1.25 g gel containing 750 micrograms estradiol.
4. Apply to correct site: Spread the gel over a large area of skin on either the outer arm and shoulder of both arms, or the mid‑inner thigh of both legs. Do not apply to breasts, genital area, or near the face.
5. Spread evenly: Use your hand to spread the gel thinly over the chosen area. If you need two pumps, apply one pump to each shoulder/outer arm (or each thigh) – do not combine two pumps on a single limb.
6. Let it dry: Allow the gel to dry for at least 5 minutes before dressing. Do not shower, bathe, or swim for at least 1 hour after application.
7. Wash hands thoroughly: After application, wash your hands with soap and water to remove any residue.
8. Cover the area: Once dry, cover the application site with clothing to prevent accidental transfer to others.

After use, replace the stopper and cap. If you forget a dose, apply it as soon as you remember unless it is less than 12 hours before the next dose; never double dose.

Dosage Guide: How Much & When

Your doctor will prescribe the lowest effective dose for the shortest duration. The standard dosage is:

• Usual starting dose: 2 pumps (2 measures) once daily – one pump on each shoulder/outer arm or each mid‑inner thigh. This provides 1.5 mg estradiol per day.
• Dose adjustment: If symptoms are not controlled, your doctor may increase the dose to up to 4 pumps (4 measures) daily – two pumps on each shoulder/outer arm or each thigh. Never exceed the prescribed dose.
• When to apply: Apply at the same time each day, either in the morning or evening. Consistency helps maintain steady hormone levels.

With or without food? Oestrogel is applied to the skin, so food has no effect. However, avoid applying immediately after a hot bath or sauna, as sweating may affect absorption.

Who Should Use Oestrogel

Oestrogel is indicated for postmenopausal women who need Hormone Replacement Therapy (HRT). It is suitable for:

• Women with moderate to severe vasomotor symptoms (hot flushes, night sweats) that significantly affect daily life.
• Women at high risk of osteoporosis who cannot take non‑oestrogen medicines.
• Women who have had a hysterectomy (no uterus) and require oestrogen‑only therapy.
• Women with an intact uterus must also take a progestogen (e.g., 12 days per cycle) to protect the endometrium, unless prescribed as part of a continuous combined regimen.
• Those who prefer transdermal administration to avoid first‑pass liver metabolism, especially women with mild liver impairment or those at increased risk of blood clots with oral oestrogens.

Before starting, your doctor will assess your personal and family medical history, perform a physical examination, and discuss the risks and benefits of HRT.

Who Should Not Use Oestrogel

Oestrogel is contraindicated in the following situations (do not use if any apply):

• Known allergy to estradiol or any excipient (carbomer, trolamine, ethanol).
• Current or past breast cancer, or suspicion of it.
• Oestrogen‑sensitive cancer (e.g., endometrial cancer).
• Unexplained vaginal bleeding.
• Untreated endometrial hyperplasia.
• Current or past venous thromboembolism (deep vein thrombosis, pulmonary embolism).
• Known thrombophilic disorder (e.g., protein C, protein S, antithrombin deficiency).
• Recent arterial thromboembolic disease (heart attack, stroke, angina).
• Liver disease with abnormal liver function tests.
• Porphyria.
• Pregnancy or breastfeeding.

If any of these develop while using Oestrogel, stop immediately and consult your doctor.

Special Conditions & Precautions

Inform your doctor if you have any of the following before starting Oestrogel, as extra monitoring or dose adjustment may be needed:

• Uterus present: You must use a progestogen to prevent endometrial hyperplasia. Unopposed oestrogen increases the risk of endometrial cancer.
• History of endometriosis or fibroids: Oestrogen may stimulate these; your doctor may prescribe a progestogen or monitor closely.
• Liver impairment: Reduced clearance of estradiol may occur; regular liver function tests are advised.
• Diabetes: Oestrogen can affect glucose tolerance; monitor blood sugar more frequently initially.
• Epilepsy or migraine: Oestrogens may exacerbate these conditions.
• Asthma, SLE, otosclerosis: HRT can worsen these; discuss with your specialist.
• High triglycerides: Oestrogen may raise triglyceride levels; monitor lipids.
• Gallstones: HRT may increase the risk.
• Hereditary angioedema: Oestrogen can trigger or worsen attacks.

Surgery

If you are scheduled for surgery, inform your surgeon that you use Oestrogel. You may need to stop using it 4–6 weeks before the operation to reduce the risk of blood clots. Your doctor will advise when to restart.

Pregnancy & Breastfeeding

Oestrogel is for postmenopausal women only. If you become pregnant while using it, stop immediately and contact your doctor. Do not use during breastfeeding as oestrogens can pass into breast milk and may affect the infant.

Accidental transfer to children

Estradiol can be transferred to children through skin contact. This may cause signs of early puberty (breast development, pubic hair). Always cover the application site with clothing after the gel dries. If accidental contact occurs, wash the child’s skin immediately with soap and water and consult a healthcare provider if any signs appear.

Interaction with other medicines

Certain medications can reduce the effectiveness of Oestrogel, leading to irregular bleeding. These include:

• Antiepileptics (phenobarbital, phenytoin, carbamazepine).
• Antituberculosis drugs (rifampicin, rifabutin).
• HIV protease inhibitors (nevirapine, efavirenz, ritonavir, nelfinavir).
• St. John’s Wort (herbal remedy).

HRT may also affect the action of lamotrigine (an antiepileptic). Tell your doctor about all medicines you take.
