Can I take Omeprazole and Pyridostigmine together?

Why this happens

Pyridostigmine works best in an acidic stomach environment. Omeprazole reduces stomach acid, which can prevent pyridostigmine from being absorbed properly into your bloodstream.

What you should do

Speak to your doctor before taking these together. They may suggest timing the doses further apart or monitoring your symptoms closely. If you notice increased muscle weakness or difficulty swallowing, contact your healthcare provider immediately.

Important precautions

Asthma or COPD

Pyridostigmine can cause narrowing of the airways and increase mucus production, which may severely worsen breathing problems or trigger an asthma attack.

Cholinergic Crisis (Overdose) - pyridostigmine

If you experience severe muscle weakness, abdominal cramps, or difficulty breathing, seek urgent medical help. These can be signs of an overdose, which can look very similar to the condition being treated.

Severe diarrhoea

Contact your doctor immediately if you develop severe or persistent watery diarrhoea, as omeprazole can increase the risk of a serious bowel infection called Clostridium difficile.

Vitamin B12 deficiency

Long-term use of omeprazole can prevent your body from absorbing Vitamin B12 properly, which may lead to nerve damage or anaemia.

Lupus (SLE)

Seek medical advice if you develop a skin rash, especially in areas exposed to the sun, as omeprazole can trigger or worsen a rare autoimmune condition called Subacute Cutaneous Lupus Erythematosus.

Food and drink warnings

Alcohol

It is best to avoid or strictly limit alcohol while taking omeprazole. Alcohol can increase the amount of acid your stomach produces, which may worsen your symptoms or make the medicine less effective. Additionally, both alcohol and omeprazole can irritate the stomach lining.

It is best to avoid or strictly limit alcohol while taking pyridostigmine. Combining alcohol with this medication can increase the risk of side effects such as dizziness, drowsiness, and blurred vision. Alcohol may also worsen the symptoms of the condition for which you are taking pyridostigmine.

General Food Timing

Omeprazole works best if you take it 30 to 60 minutes before a meal, preferably breakfast. Taking it with food can slow down how quickly the medicine starts to work.
