Key Information
What is Acyclovir Stada Tablet and who is it for?
Acyclovir Stada Tablet is a prescription medicine that contains aciclovir, and it comes in three strengths: 200mg, 400mg and 800mg.
In Malaysia, you can only get it with a valid prescription from a registered doctor. It’s meant only for the person it was prescribed to, so please don’t share it, even with someone close to you.
Your doctor decides whether it’s right for you, and which strength to start with. If you have questions at any point, our pharmacists are happy to help.
Which strength should I choose?
There are three strengths, and the right one depends on what your doctor prescribed for you. That’s why we’ll always confirm it with you during your consultation, so you never have to guess.
If you already have a prescription, simply choose the strength written on it. If you’re not sure which one it says, send us a photo on WhatsApp and we’ll help you check.
Please don’t switch strengths on your own, and don’t change how often you take it unless your doctor tells you to. It’s also best to check with your doctor before you stop, delay or change your dose, even if you feel fine.
Delivery, packaging and ordering
Ordering is simple. Search for Acyclovir Stada Tablet on the DoctorOnCall website, choose your strength and place your order. A licensed doctor then reviews your order through an online consultation, and a registered pharmacist prepares it before it’s sent out.
We pack every order discreetly, so nothing on the outside shows what’s inside. Delivery is free when you spend RM120 or more.
Every pack also carries its MAL number, so you can double-check it with the Ministry of Health Malaysia if you’d like.
Side effects, safety basics, and when to get help
Most people take Acyclovir without any trouble, but it helps to know what to look out for. Some people get a headache, an upset stomach or feel a little tired. These usually settle on their own.
Please use it with extra care if you have kidney problems, and tell us if you’re older, as your kidneys may need a gentler approach. The same goes for liver problems, so let your doctor know about both. Tell your doctor too if you take lithium, as acyclovir may affect lithium levels in your blood.
Please don’t take it if you’ve ever had an allergic reaction to acyclovir, valacyclovir, or any ingredient in the tablet. If you’re pregnant, speak to your doctor before you take it.
Get help straight away if you notice swelling of the face or lips, trouble breathing, a rash that spreads, passing much less urine than usual, or feeling confused.
How to take your Acyclovir Stada Tablet
Check with your doctor first. Make sure Acyclovir Stada and your strength are right for you, and mention the other medicines you take, any kidney or liver conditions, and any allergies. It helps your doctor pick the right strength for you.
Take it the way your doctor said. Your doctor sets how much you take and how often, so stick to that. Spreading your doses evenly through the day, as prescribed, usually works best.
Swallow it with water. Take it with or after food if you can, as it can be gentler on your stomach. Swallow the tablet whole with a full glass of water, and drink plenty of water through the day to help your kidneys.
If you miss a dose, don’t double up. Take it as soon as you remember, unless your next dose is almost due, in which case just skip the missed one. If you often forget, let your doctor or pharmacist know. They can help you find a routine that works.

If your order arrives damaged
We’re sorry if that happens. Please don’t use the tablets if the box is damaged, the strip is torn or opened, or the pack looks like it’s been tampered with.
Take a few photos of the box and the strip, and message us on WhatsApp. If it’s a verified delivery issue, we’ll send you a replacement at no extra cost.
Returns policy
Acyclovir Stada is a prescription medicine, so we can’t take it back once it’s left our pharmacy. The exception is a verified delivery issue, like damaged packaging, or a wrong or missing item.
If something’s wrong with your order, message us within 24 hours of delivery and we’ll sort it out together.
The dose and duration of Acyclovir Stada Tablet depend on the type and severity of the infection being treated – for example, cold sores, genital herpes, or chickenpox/shingles each have different typical regimens, and doses may be adjusted in people with reduced kidney function. Your doctor will prescribe the specific dosing schedule and course length for your condition.
Storage Instructions
Do
Keep it below 30°C in a cool, dry place, away from direct sunlight. Heat and humidity can change how the tablets look and feel.
Leave the tablets in their original strip until you’re ready to take one, so they stay protected from moisture and light.
Keep them out of the reach and sight of children.
Check the expiry date on the pack before each use. Shelf life is typically 3 years from the manufacturing date, and the date is printed on the pack.
Store them somewhere dry that’s easy to remember, like a bedroom drawer or kitchen cupboard away from the stove and sink.
Don't
Don’t leave them in a hot car, on a sunny windowsill, or in the bathroom.
Don’t use them if the tablets look, smell or feel different from usual. Ask your pharmacist instead.
Don’t take them after the expiry date.
Don’t move them into an unlabelled container, as it’s easy to forget what they are.
Don’t share them with anyone. They were prescribed for you.
Don’t throw unused or expired tablets in the toilet or household rubbish. Take them to a pharmacy for safe disposal.

Contraindications

Drug / Food Interactions

Mycophenolate mofetil (used after organ transplant) may have increased blood levels when combined with aciclovir
Ensure adequate fluid intake, as dehydration increases the risk of aciclovir affecting the kidneys

Frequently Asked Questions
Yes. Acyclovir Stada Tablet is a prescription-only medicine (POM). It can only be supplied against a valid prescription written by a registered doctor, and it should be used only by the person named on the prescription label.
Acyclovir Stada Tablet is supplied as a tablet and contains Aciclovir. The full composition is listed in the Composition section on this page and on the product packaging.
Malaysian rules for prescription medicines limit public product pages to product, safety and handling information. Your doctor decides whether this medicine is appropriate for you and will explain it during your consultation, and your pharmacist can answer further questions when the medicine is dispensed.
Follow your doctor’s instructions and the directions on the dispensing label without changing them. If anything on the label is unclear, check with your pharmacist before taking the first dose, and read the Directions for Use section on this page.
Take it as soon as you remember, unless your next dose is nearly due. In that case skip the missed dose and carry on with your usual schedule. Never take two doses together to make up for a missed one. If you miss doses often, tell your doctor or pharmacist.
Store below 30°C in a dry place, away from direct sunlight and out of reach of children. Keep it in the original pack until use, and do not use it after the expiry date printed on the packaging.
Tell your doctor or pharmacist about any reaction that concerns you, and seek medical care immediately for signs of a severe reaction such as difficulty breathing, swelling of the face, lips or throat, or a widespread rash. Reported reactions are listed in the Side Effects section on this page.
No. Speak to your doctor before stopping, pausing or changing the dose, even if you feel well or think you no longer need the medicine.
Customers in Malaysia can complete an online consultation with a DoctorOnCall doctor, who decides whether a prescription is appropriate, or upload a valid prescription already issued by their own doctor.
Orders going to Singapore are dispatched from Malaysia as an international delivery, so you need to hold a valid prescription or doctor’s letter for the medicine. Check the consultation and prescription upload options shown at checkout for your delivery address before placing the order.
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.
