Overview
Lenzetto 1.53mg Transdermal Spray is a transdermal spray with Estradiol hemihydrate (equivalent to 1.53mg estradiol per spray) declared as its active content. It is supplied in a pack size of 8.1ml.
This is a non-prescription product and can be purchased without a prescription. Only product, safety and handling details are published on this page.
An online consultation with a DoctorOnCall doctor or pharmacist is available for this product, and a registered pharmacist reviews each order before dispatch to Malaysia or Singapore. Follow the directions on the label and on the leaflet inside the pack.
Directions for Use
Lenzetto must only be used exactly as prescribed by the assessing doctor. It is typically sprayed once daily onto a clean, dry area of the inner forearm, allowed to air-dry for a couple of minutes before clothing touches the site, and the application area should be rotated slightly each day. Hands should be washed after each application, and the sprayed skin should not be washed, rubbed, or covered with sunscreen or moisturiser for at least one hour afterwards.
Dosage
The usual starting dose is one spray (1.53mg estradiol) once daily, and the prescribing doctor may adjust this up to a maximum of three sprays a day depending on how symptoms respond. Dosage must never be increased, decreased, or stopped abruptly without medical advice, as the appropriate dose depends on individual symptom control and risk assessment.
Shelf Life
Lenzetto should be used within the manufacturer’s stated shelf life printed on the carton and pump bottle, and should not be used past its expiry date. Once first opened, the metered-dose pump should be used within the period stated in the product leaflet, after which it should be discarded even if some solution remains.
Storage Instructions
Store Lenzetto below 25°C in a cool, dry place away from direct sunlight and out of reach of children and pets. As the spray contains alcohol and is flammable, keep it away from naked flames, lit cigarettes, and other sources of ignition until the sprayed area has fully dried.

Drug / Food Interactions
Enzyme-inducing medicines such as rifampicin, carbamazepine, and phenytoin may reduce the effectiveness of estradiol
St John’s Wort (a herbal supplement) can lower estradiol levels in the blood
Some antibiotics and antifungal medicines may alter how estradiol is broken down in the body
Concurrent use with blood thinners or anticoagulants should be discussed with a doctor, as HRT can affect clotting risk
Smoking increases the risk of blood clots when combined with hormone therapy
Quick Tips
Apply Lenzetto at roughly the same time each day for consistent hormone levels
Allow the sprayed area to air-dry fully before dressing or applying other skin products
Never apply near an open flame or while smoking until the site is completely dry

Relevant Information
Lenzetto is dispensed only against a valid prescription obtained through an online consultation with a DoctorOnCall doctor, who will assess your medical history, menopausal symptoms, and risk factors such as personal or family history of breast cancer or blood clots before prescribing. Hormone replacement therapy is generally recommended at the lowest effective dose for the shortest duration needed to control symptoms, with periodic medical review to reassess ongoing need and monitor for side effects. Continuing regular follow-ups, including breast examinations and blood pressure checks as advised by your doctor, is an important part of using this medicine safely.

Within Malaysia, standard delivery takes 3 to 5 working days. Same-day delivery is available in the Klang Valley for orders placed before 12pm; orders placed after 12pm arrive by the end of the next day.
Orders to Singapore are sent as international deliveries and take 5 to 9 working days. A lump-sum shipping and handling fee applies to every overseas delivery and is shown at checkout.
Customers in Malaysia can pay by FPX online banking, credit or debit card (Visa and Mastercard), and supported e-wallets including Touch ‘n Go eWallet, GrabPay and ShopeePay.
FPX and local e-wallets are tied to Malaysian bank and wallet accounts, so if your delivery address is in Singapore, use the payment options displayed at checkout for that address rather than assuming the same list applies.
Yes. DoctorOnCall ships to Singapore as an international order dispatched from Malaysia, arriving in 5 to 9 working days with a lump-sum shipping and handling fee.
Singapore’s Health Sciences Authority (HSA) allows personal imports of up to three months’ supply of a medicine for your own use or an immediate family member’s, as long as it contains no controlled drugs, psychotropic substances or prohibited items. Keep the product in its original labelled packaging and keep a copy of your prescription or doctor’s letter with it. Quantities above three months’ supply, and medicines containing controlled substances, require prior HSA approval.
Products listed on DoctorOnCall are registered with Malaysia’s Ministry of Health for supply in Malaysia, and each pack carries its MAL registration number.
An order delivered to Singapore arrives as a personal import of a Malaysia-registered product; HSA product registration is not required for personal-use quantities, but it is also not the same as a product registered for sale in Singapore. If you need a locally registered Singapore product, buy it from a pharmacy in Singapore.
DoctorOnCall’s customer care team handles order, delivery and product queries through the contact channels on the site, including WhatsApp and the online help centre.
For deliveries to Singapore, allow more time before chasing an order than you would for a local Malaysian delivery, as the parcel passes through customs clearance and tracking updates can appear later in the journey.
