Tolterodine cost without insurance
Cash prices for Tolterodine without insurance vary widely by pharmacy, strength and quantity — the same prescription can cost very different amounts at two pharmacies in the same town. That is the problem a membership solves.
Tolterodine is on Tab's covered $0 generic list. With an active Tab membership, every covered strength is $0 — not a percentage off, not a coupon that changes month to month — at participating pharmacies nationwide or through mail order. You do not need insurance, and Tab works whether or not you have a health plan.
Tab is a membership, not insurance. Covered medications require a prescription from a licensed clinician.

ADVERSE REACTIONS Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The most common adverse reactions (incidence > 4% and >placebo) were dry mouth, headache, constipation, and abdominal pain. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Inventia Healthcare Limited, at 1-800-270-7585 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience The efficacy and safety of tolterodine tartrate extended-release capsules was evaluated in 1073 patients (537 assigned to tolterodine tartrate extended-release capsules; 536 assigned to placebo) who were treated with 2, 4, 6, or 8 mg/day for up to 15 months.

Tolterodine drug interactions
7. DRUG INTERACTIONS Potent CYP3A4 inhibitors: Coadministration may increase systemic exposure to tolterodine tartrate extended-release capsules. Reduce tolterodine tartrate extended-release capsules dose to 2 mg once daily. ( 7.2 ) Other Anticholinergics (antimuscarinics): Concomitant use with other anticholinergic agents may increase the frequency and/or severity of dry mouth, constipation, blurred vision, and other anticholinergic pharmacological effects. ( 7.6 ) 7.1 Potent CYP2D6 Inhibitors Fluoxetine, a potent inhibitor of CYP2D6 activity, significantly inhibited the metabolism of tolterodine immediate release in CYP2D6 extensive metabolizers, resulting in a 4.8-fold increase in tolterodine AUC.
