What is the generic for Singulair?
Singulair is the brand name for montelukast (a leukotriene receptor antagonist). The generic versions use the same active ingredient: montelukast. [1]
What are common generic names you’ll see at the pharmacy?
You may see montelukast listed as the active ingredient on the prescription label, often as:
- Montelukast tablets (including 10 mg)
- Montelukast chewable tablets (often 4 mg or 5 mg, depending on age/indication) [1]
Are generic montelukast and brand Singulair interchangeable?
Generic montelukast is designed to be equivalent to Singulair because it contains the same active ingredient (montelukast). In practice, the key thing is matching the same drug form and strength (for example, tablet vs. chewable, and the mg dose). [1]
Why do some montelukast versions cost less than others?
Price differences usually come from factors such as:
- Brand vs. generic pricing
- Different strengths or formulations (tablet vs. chewable)
- Pharmacy-specific pricing and coverage
If you tell me your dose (mg) and whether it’s tablets or chewables, I can help you identify what to ask for at the pharmacy.
