Tegaserod Side Effects and Adverse Reactions

Like all medications, Tegaserod may cause side effects. Some are more common, while others are rare but potentially serious. If you experience any side effects, contact your healthcare provider immediately. You can also schedule a telemedicine visit to discuss your symptoms.

Contraindications for Tegaserod

A contraindication is a specific situation or condition where a medication should not be used because it may cause harm. It’s important to be aware of these situations to avoid serious side effects or complications.

Tegaserod is contraindicated in the following situations:

1. History of heart attack, stroke, or unstable angina: Tegaserod may increase the risk of cardiovascular events, especially in individuals with a history of heart problems. It is not recommended for people with these conditions.
2. Severe kidney impairment: Tegaserod is processed by the kidneys. If kidney function is impaired, the drug may accumulate in the body, leading to potential toxicity.
3. Severe liver impairment: The liver also plays a role in processing Tegaserod. If liver function is compromised, the medication may not be broken down properly, which could lead to harmful effects.
4. Bowel obstruction: Tegaserod increases intestinal movement. If there is a blockage, this could lead to complications such as perforation (a hole in the bowel) or worsening of the obstruction.
5. Gallbladder disease: Tegaserod can affect the digestive system and may worsen gallbladder issues, leading to pain or other complications.

Drug Interactions with Tegaserod

Before starting Tegaserod, inform your healthcare provider about all medications you are taking, including over-the-counter drugs, supplements, and herbal products. Some medications can interact with Tegaserod, potentially causing harmful side effects or reducing its effectiveness.

Medications that may interact with Tegaserod include:

1. Warfarin (Coumadin): This blood thinner may increase the risk of bleeding when taken with Tegaserod.
2. Ketoconazole (Nizoral): An antifungal medication that can increase Tegaserod levels in the body, raising the risk of side effects.
3. Atorvastatin (Lipitor): A cholesterol-lowering medication that may interact with Tegaserod, increasing the risk of muscle-related side effects.
4. Digoxin (Lanoxin): A heart medication that may have altered effectiveness when taken with Tegaserod.

Tegaserod in Pregnancy

Is it safe to take Tegaserod when pregnant?

Tegaserod is generally not recommended during pregnancy unless absolutely necessary. There is limited data on its safety in pregnant women, and animal studies suggest potential risks to the developing fetus. If you are pregnant or planning to become pregnant, it’s important to discuss the potential risks and benefits of Tegaserod with your healthcare provider. Our telemedicine providers are available to help you make an informed decision about your treatment options.

Tegaserod While Breastfeeding

Is it safe to take Tegaserod while breastfeeding?

There is not enough information to determine whether Tegaserod passes into breast milk or if it could affect a nursing infant. Due to this lack of data, it is generally advised to avoid Tegaserod while breastfeeding. If you are breastfeeding or planning to breastfeed, consult your healthcare provider to discuss safer alternatives. You can also speak with one of our telemedicine providers to explore other treatment options that may be more suitable for you and your baby.

Estimated Cost of Tegaserod Medication

The estimated cost of a 30-day supply of Tegaserod without insurance typically ranges from $450 to $500. However, using a GoodRx coupon, the price may be reduced to around $400. Prices can vary depending on the pharmacy, so it’s worth checking for discounts or savings programs.

Possible Alternatives to Tegaserod

If Tegaserod is not the right option for you, other treatments and lifestyle changes may help manage your symptoms. Always consult your healthcare provider before making any changes to your treatment plan. Our telemedicine providers are available to help you explore these alternatives.

1. Irritable bowel syndrome (IBS): Alternatives include dietary changes (such as a low-FODMAP diet), fiber supplements, probiotics, and medications like lubiprostone (Amitiza) or linaclotide (Linzess).
2. Constipation-predominant IBS: In addition to dietary changes and fiber supplements, medications like polyethylene glycol (MiraLAX) or prucalopride (Motegrity) may be considered.
3. Functional constipation: Increasing fiber intake, staying hydrated, and engaging in regular physical activity can help. Medications like bisacodyl (Dulcolax) or lactulose may also be effective.
4. Chronic constipation: Lifestyle changes such as a high-fiber diet, regular exercise, and adequate water intake are important. Medications like lubiprostone (Amitiza) or linaclotide (Linzess) may also be prescribed.
5. Abdominal pain, bloating, and discomfort: Antispasmodic medications like dicyclomine (Bentyl) or hyoscyamine (Levsin) may help relieve these symptoms. Probiotics and dietary changes can also be beneficial.
6. Gastrointestinal motility disorders: Medications like metoclopramide (Reglan) or erythromycin may be used to improve gut motility. Dietary adjustments and physical activity can also play a role in managing symptoms.
7. Bowel irregularity: A high-fiber diet, increased water intake, and regular exercise can help regulate bowel movements. Over-the-counter laxatives like polyethylene glycol (MiraLAX) may also be useful.
8. Colonic inertia: This condition may require more specialized treatment, including medications like prucalopride (Motegrity) or, in severe cases, surgery. Consult your healthcare provider for the best approach.
