    How effective is Omeprazole?

    Omeprazole is an approved brand and generic drug that is used to treat a variety of digestive conditions caused by excessive production of gastric acid. The active ingredient, which also goes by the same name as that of the drug, omeprazole is highly effective in preventing the secretion of excess gastric acid. This allows the intestinal and stomach ulcers to heal as well as relieving heartburn discomfort when used as advised.

    Can I buy Omeprazole online?

    Although omeprazole is often available as a prescribed drug, you can still buy over-the-counter omeprazole tablets/capsules. These tablets are used to treat frequent heartburn that occurs a few times within a given period. 

    You can buy the tablets online packs of 28 tablets that can be sent to you by Next Day Delivery. You are free to book an appointment with a health expert at Click Pharmacy to discuss how best to use this drug.

    What dose should I choose?

    A pack of omeprazole tablets come in 28 tablet size. Each of these tablets contains 20 or 40 mg of the active ingredient omeprazole, which should be taken once daily for at least 4 weeks by patients above 18 years. 


    How should I take Omeprazole?

    Omeprazole is taken orally in the form of tablets or capsules, as well as suspension which is administered using a syringe. Usually, the medication is taken once a day, first thing in the morning. It does not upset the stomach so that you can take it before or after a meal.

    Note that pharmacists and doctors do not recommend taking the medication for immediate relief of acid reflux symptoms, particularly heartburn. Instead, it should be taken for 4 to 8 weeks but some patients may end up taking for 14 weeks, depending on the severity of the symptoms. Also, it may take several days for this medication to alleviate stomach pains which is why it should be taken with antacids, as advised by the doctor. If you are taking sucralfate, take omeprazole half an hour before sucralfate. 

    When taking omeprazole capsules/tablets, you should not chew or crush them in food, since doing so prevents the activation of the medicinal properties of the drug. If unable to swallow the capsules, some brands of omeprazole capsules can be opened and the contents mixed in a small amount of water that should be taken right away.  You should take to a pharmacist to know which type of capsules can be opened. 

    If you forget to take the medication, take it as soon as you remember. However, if it is within 12 hours to your next dose, you can skip the missed dose. It would be best if you didn't take a double dose to make up for a forgotten dose.

    How does Omeprazole work?

    The active ingredient omeprazole works by targeting proton pumps in your stomach, hence its classification under proton pump inhibitor class of drugs. These tiny pumps are responsible for the chemical reaction that produces stomach acid. Once omeprazole is ingested, it is absorbed in the bloodstream and signals the acid-forming cells on the stomach lining, to reduce the amount of acid they produce. With the acidity reduced, the patient is relieved of acid reflux symptoms and the intestinal ulcers start healing.

    How long should I take Omeprazole before I notice any difference?

    It takes 2 to 4 days of consumption to realize the full effect, as such it should not be taken to provide immediate relief. Instead, it is meant to treat acid reflux symptoms occurring a couple of times in a week. Usually, omeprazole is prescribed for 8 weeks when treating short-term gut conditions, but the period can be extended to 14 weeks if the patient's condition does not improve. 

    If you are self-medicating, you should not take omeprazole for more than 2 weeks, unless advised otherwise by a pharmacist or doctor.

    What are the side effects of Omeprazole?

    Similar to other PPIs, most patients well tolerate omeprazole. However, it causes some mild side effects on a few patients, which fade away with time. 

    Some of these common side effects include:

    • Diarrhoea

    • Nausea

    • Headaches

    • Rash

    • Abdominal pain

    In addition to these effects, younger patients, aged 1 to 17 years, complain about fever and breathing issues such as pharyngitis and sinus infections. 

    Using omeprazole for an extended period, more than 1 year, can make it difficult for your body to absorb vitamin B-12. The deficiency manifests itself through feeling nauseated, numbness, poor muscle coordination and changes in menstruation cycle. Serious side effects that should warrant a visit to the doctor include bone fractures, severe diarrhoea, pale skin and swellings in the mouth. 

    If you experience any of these severe side effects, be sure to consult us at Click Pharmacy for urgent assistance.

    When shouldn't I take Omeprazole?

    You should not take this treatment if you are on any antifungal, bloodthinning, and anti-epilepsy medications. Heart-related drugs such as digoxin and some antibiotics, do not go well with omeprazole. These medications make it more likely to develop severe omeprazole side effects. Thus you should inform your doctor if you are on any medication before beginning omeprazole treatment. 

    Nonetheless, the treatment is safe for pregnant and nursing mothers. But first, you are advised to try alternative treatment methods such as eating smaller meals and less spicy foods, to ease acid reflux symptoms, before you can start treatment.

    What is the difference between Omeprazole and Nexium/Aciphex?

    Omeprazole and Nexium as well Aciphex are similar since they are all proton pump inhibitors. They can be prescribed to treat ulcers and GERD. 

    The only difference is in their active ingredient component. Both omeprazole and Nexium contain the same active ingredient, but omeprazole contains two isomers of the ingredient while Nexium contains only one isomer. Aciphex, on the other hand, contains rabeprazole as the active ingredient, which is also under the proton pump inhibitor class of medications. 

    Side Effects

    After using Omeprazole Capsules you are likely to experience lots of different side effects. Common side effects and how to overcome them include the following:

    • Headaches: rest and drink plenty of water to ensure you are hydrated
    • Feeling sick: take your medication after a meal or snack
    • Diarrhoea: drink lots of fluids to prevent dehydration
    • Stomach pains: eat smaller more frequent meals
    • Constipation: try to increase your intake of foods that contain lots of fibre
    • Wind: avoid foods such as lentils, beans and cereals.
