Pharmacist tips for Rolaids
- If you take prescription medications, talk to your provider or pharmacist before taking Rolaids. Sometimes calcium and magnesium will affect how much medication is absorbed. Ask them if any of your medications interact. Usually the medications have to be taken a few hours before or after Rolaids.
- Take Rolaids at the first sign of stomach discomfort for it to work the best.
- You can continue to take Rolaids throughout the day whenever you have symptoms. But, don't take more than the maximum recommended amount of tablets per day (see your product label for details).
- Contact your provider if your symptoms don't improve after 2 weeks, and you're still needing to use Rolaids regularly (for example, every 2 hours). Also contact them if your symptoms are getting worse or feel severe. Your provider might need to check to see if you need more medical attention.
- There are a lot of different antacid products that have similar ingredients. Some contain simethicone (Gas-X) and others famotidine (Pepcid). Always check the active ingredients on the back so you know what you're buying. If you're not sure, ask your pharmacist for help.
Risks and warnings for Rolaids
Rolaids can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Medication interactions
- Risk factors: Taking certain prescription medications
Rolaids interacts with many prescription medications, which can lower their absorption and weaken their effect. You might need to separate Rolaids from other medications by several hours. Talk to your provider or pharmacist about the medications you're currently taking so they can check for interactions and help you manage them.
High blood calcium
- Risk factors: Kidney problems | Dialysis | Overactive parathyroid gland
Rolaids contains calcium, which can build up in your blood and lead to dangerously high calcium levels. There's more risk of high calcium if you have a condition (e.g., kidney problems) that causes you to have problems with your calcium levels. Talk to your provider before taking Rolaids if you've ever been told you have abnormal calcium levels.
