Shipping Update

We are now seeing improvements in our shipping times. However, things are not yet back to normal and there are still some delays occurring.

Our normal shipping time averages 1 - 2 weeks. Shipments may potentially take an additional 2 – 4 weeks to arrive, depending on the source country of your order. Shipments from the United Kingdom and Canada are generally quicker than from other countries.

Please note that these times are averages and individual shipping times will vary. We highly recommend that you place your order at least 2 – 4 weeks or more ahead of your normal reorder time to avoid running out of your medication.

These delays are temporary, and we thank the shipping and delivery personnel who are working hard for all of us during this global crisis.

Full information about Mestinon SR

General Information on Mestinon SR

Mestinon SR is specifically recommended to improve muscle strength in patients suffering from neuromuscular disorders such as myasthenia gravis. It is also used to treat military personnel who have been exposed to nerve gas.

Pyridostigmine, the main active ingredient in the medication, belongs to a group of drugs known as anticholinesterase muscle stimulants. It works by inhibiting the breakdown of acetylcholine in the body. Acetylcholine is a natural substance required by the body for normal muscle functioning.

Mestinon SR is available in the form of an extended release tablet or time span tablet. The extended release tablet is different from a regular tablet. In the extended release tablet, the release of Mestinon SR takes place in a controlled manner over a period of time. Each Mestinon SR tablet contains 180mg Pyridostigmine bromide.

Mestinon SR is a prescription medication and may cause health complications if used for unintended purposes. To reduce the risk of side effects and health complications, consult your doctor before you buy Mestinon SR.

Side effects of Mestinon SR

People with medical problems such as bladder or bowel obstruction or serious stomach conditions such as peritonitis should not use Mestinon SR. Inform your doctor if you have kidney disease or asthma before starting the treatment.

Every drug has side effects. Some people may experience mild to serious side effects after taking a dose of Mestinon SR. Watery eyes, cold sweat, mild nausea, mild rashes, vomiting, urinating more than usual, upset stomach, tingling or warmth, pale skin, or itching are some less serious side effects associated with the drug. These side effects generally wane over time. However, if they persist or become bothersome, consult your doctor.

Mestinon SR may also cause severe side effects such as muscle twitching, severe diarrhea or vomiting, vision problems, extreme muscle weakness, slurred speech, cough with mucus, seizures, panic attacks, or confusion. Consult your doctor immediately if you experience or notice any severe side effects after taking a dose of Mestinon SR.

Dosage of Mestinon SR

Your doctor will give you specific instructions regarding the dosage. The dosage of Mestinon SR mainly depends on two factors- the medical needs of the patient and his/her clinical response to the drug. You are required to swallow the Mestinon SR tablet whole. Do not crush or chew it. You can take the medication with or without food.

The recommended dosage to control the symptoms of myasthenia gravis is one to three Mestinon SR tablets daily. However, a doctor may recommend a different dosage to suit individual requirements. Mestinon SR is an extended release tablet, so the minimum interval between two doses should be 6 hours.


If you are using other drugs, then there is a possibility that Mestinon SR may interact with them and cause side effects. Mestinon SR may interact with medicines such as Benztropine, Dimenhydrinate, Scopolamine, Atropine, Clidinium, Clozapine, Belladonna, Methscopolamine, Mepenzolate, Glycopyrrolate, urinary or bladder medications, allergy medicines, sleeping pills, cold medicines, irritable bowel syndrome medications, some steroids, drugs to treat Alzheimer's and dementia, heart rhythm medications, or bronchodilators.

Before you buy Mestinon SR, inform your doctor about every medicine you are taking, which includes prescriptions medicines, over the counter drugs, and herbal supplements.
