Ranolazine

Ranolazine is used alone or with other medications to treat chronic angina (ongoing chest pain or pressure that is felt when the heart does not get enough oxygen). Ranolazine is in a class of medications called anti-anginals. The exact way that ranolazine works is not known at this time.

🔔 How should this medicine be used?

Ranolazine comes as an extended-release (long-acting) tablet to take by mouth. It is usually taken with or without food twice daily. Take ranolazine at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take ranolazine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Swallow the tablets whole; do not break, chew, or crush them.

Your doctor will probably start you on a low dose of ranolazine and gradually increase your dose.

Do not take ranolazine to treat a sudden attack of angina. Your doctor will tell you what you should do if you experience an attack of angina. Make sure that you understand these directions.

Ranolazine may help control your condition but will not cure it. Continue to take ranolazine even if you feel well. Do not stop taking ranolazine without talking to your doctor.

🔔 What should I know about storage and disposal of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
