Oposim is listed as a pregnancy category C. While there are no well-controlled studies that have been done in pregnant women, there have been some deficits reported in mothers who were on Oposim during pregnancy. If you are on Oposim and become pregnant or are considering starting Oposim during pregnancy, discuss this with your medical provider. Together you can determine if the benefits outweigh the risks in your situation.
After giving birth, Oposim is excreted in breast milk and should be used with caution in nursing mothers.
Because of the variable bioavailability of Oposim, the dose should be individualized based on response.
How to take it
Oposim doesn't usually upset your tummy so you can take it with or without food. It's best to do the same each day.
Swallow the tablets whole with a drink of water. If you find them difficult to swallow, some brands have a score line to help you break the tablet in half. Check the information leaflet for your brand to see if you can do this.
If you're taking Oposim as a liquid, it will come with a plastic syringe or spoon to help you measure out the right dose. If you don't have one, ask your pharmacist for one. Don't use a kitchen teaspoon as it won't give you the right amount of medicine.
Before taking this medicine
You should not use Oposim if you are allergic to it, or if you have:
very slow heart beats that have caused you to faint; or
a serious heart condition such as "sick sinus syndrome" or "AV block" (unless you have a pacemaker).
Babies who weigh less than 4.5 pounds should not be given Hemangeol oral liquid.
To make sure Oposim is safe for you, tell your doctor if you have:
a muscle disorder;
bronchitis, emphysema, or other breathing disorders;
low blood sugar, or diabetes (Oposim can make it harder for you to tell when you have low blood sugar);
slow heartbeats, low blood pressure;
congestive heart failure;
liver or kidney disease;
a thyroid disorder;
pheochromocytoma (tumor of the adrenal gland); or
problems with circulation (such as Raynaud's syndrome).
It is not known whether Oposim will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant while using Oposim.
Oposim can pass into breast milk and may harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
Oposim is most widely used for heart conditions. It is one of the medications approved to lower blood pressure. It can control heart rate in people who have fast heart rhythms, such as atrial fibrillation or ventricular tachycardia. Many people also use Oposim to prevent migraines or reduce symptoms of tremors. The liquid formulation is also approved for infants who have proliferating infantile hemangioma.
3. Who can and can't take Oposim
Oposim can be taken by adults and children. But it is not officially approved for treating high blood pressure in children under 12 years old.
It isn't suitable for everyone. To make sure it is safe for you, tell your doctor before starting Oposim if you have:
- had an allergic reaction to Oposim or any other medicine in the past
- low blood pressure or a slow heart rate
- heart failure which is getting worse
- severe blood circulation problems in your limbs (such as Raynaud's phenomenon), which may make your fingers and toes tingle or turn pale or blue
- metabolic acidosis - when there is too much acid in your blood
- lung disease or asthma
Tell your doctor if you're trying to get pregnant, are already pregnant or if you're breastfeeding.
Drug to treat stomach ulcers
Taking cimetidine with Oposim can increase the levels of Oposim in your blood. This can cause more side effects.
7. Pregnancy and breastfeeding
Oposim isn't thought to be harmful during pregnancy, but it is not possible to be certain. So if you're trying to get pregnant or you're already pregnant, talk to your doctor about the benefits and possible harms of taking Oposim. There may be other medicines that are safer for you.
For more information about how Oposim can affect you and your baby during pregnancy, visit the Best Use of Medicines in Pregnancy (BUMPS) website.
Oposim and breastfeeding
It is usually safe to take Oposim if you're breastfeeding. This is because only small amounts get into breast milk, which is not enough to cause any problems to your baby.
However, speak to your doctor before taking Oposim if your baby was premature or has any health problems.
Before Taking Oposim
Before taking Oposim for anxiety, it is important you talk about the medication with your physician and your mental health provider. They can help you determine if this medication is appropriate for you. For some medical conditions, Oposim is not a good medication to take. There are also some forms of anxiety that do not benefit from using Oposim.
For regular (short-acting) Oposim: Take the missed dose as soon as you remember. Skip the missed dose if your next dose is less than 4 hours away. For extended-release Oposim (Inderal LA, InnoPran XL and others): Take the missed dose as soon as you remember. Skip the missed dose if your next dose is less than 8 hours away. Do not take extra medicine to make up the missed dose.
